                                         SUMMARY

                 A total of 29 fish species representing 13 families were
            collected in a survey of 21 stations at 10 Somerset County
            streams to determine utilization by anadromous fish species.
            Sampling for adult fish and early life history stages commenced
            on March 4 and continued through May 17. Collecting gear
            included plankton net, trap net and electrofisher. Anadromous
            fish species collected included alewife, blueback herring, yellow
            perch and white perch. Yellow perch and white perch were the
            first anadromous species collected (March 13 collections) and
            generally were seen throughout the study. River herring were
            initially collected about March 13 and occurred sporadically
            throughout the study. Based on occurrence of adult fish and
            early life stages tidal freshwater portions of Somerset Creek,
            Kings Creek, Taylor Branch, and Wicomico Creek appeared to be
            most important to anadromous spawners. Streams mot supporting
            anadromous species such as Rehobeth Branch, Marumsco Creek, or
            such as Manokin Branch which had poor utilization by andromous
            species, tended to be channelized or had minimal to no buffers in
            agriculatural areas.











                                      1. INTRODUCTION


                  Directives for Local Program Development (14.15.10)
             contained in Subtitle 15 of the Chesapeake Bay Critical Area
             commission, criteria for Local critical Area Program Development
             (COMAR 14.15.10) indicate that in developing their Critical Area
             Programs, local jurisdictions shall inventory or map the
             watersheds of anadromous fish spawning streams. The objective of
             this study was to inventory streams within Somerset County to
             determine use by spawning migratory species. Streams were
             sampled with fish traps, electrofisher, and plankton nets to
             determine the presence of either spawning adults or early life
             history stages.

             1.A. Background Life History Information

                  Of the 260 fish species that occur in the Chesapeake Bay,
             the most sought after by both sport and commercial fishermen are
             the migratory species. These include anadromous fishes such as
             the herrings including American shad (Alosa sapidissima),
             blueback herring (Alosa aestivalis), alewife (Alosa
             pseudoharengus), and hickory shad (Alosa mediocris) that spend
             most of their adult lives in saltier coastal waters but return to
             freshwater to spawn, as well as the semi-anadromous species such
             as white perch (Morone americana) and yellow perch (Perca
             flavescens) which undergo large scale movements into head water
             streams to spawn. Spawning occurs in spring during increasing
             water temperatures.

             1.A.1. River Herring

                  Blueback, alewife, and American shad are the most abundant
             herrings in the Chesapeake Bay and are found throughout all parts
             of the Bay and its tributaries. Hickory shad were historically
             abundant in the.bay area but numbers are exceptionally low in
             recent times. Peak spawning activity of American shad generally
             occurs from 140 to 210 C. A variety of substrate types may be
             used for spawning but preferred areas are over sand and gravel
             bottom where there is sufficient water velocity to eliminate silt
             deposits. Active spawning occurs over a wide range of velocities
             but generally from 1 - 3 ft/sec. After spawning, adult shad
             return to the sea, leaving the Bay by June. Young shad remain in
             the Bay and its tributaries throughout the summer, some returning
             to the sea in the fall (Lippson 1973; Facey and Van Den Avyle
             1986; Stier and Crance 1985).

                  Alewife runs usually occur from March through April,
             blueback runs from the last half of April through the first half
             of May. Males arrive at mouths of spawning rivers earlier than
             females. Spawning environments vary from streams only a few
             yards wide and a few inches deep to large rivers such as the
             Delaware and Potomac. Blueback herring prefer spawning sites

                                             2









           with fast currents and associated hard substrates. In contrast,
           alewives select a wide variety of spawning site, using standing
           water as well as mid-river sites. Spawning activities of both
           species occur diurnally and nocturnally, though the greatest
           activity apparently is nocturnal. Both males and females migrate
           rapidly downstream after spawning, and total spawning time for a
           single migratory group may be 5 days or less (Lippson 1973; Fay
           et al. 1983). However, numerous migratory groups typically
           utilize a stream reach.


           I.A.2. White Perch

                White perch are resident, semi-anadromous fish in the
           Chesapeake Bay. An ubiquitous, abundant species they can be
           found in all brackish water and tidal freshwater areas at one
           time or another. As early as March, ripe individuals move
           upstream to tidal freshwater or nearly freshwater to spawn,
           remaining there often until early June. Favored within these
           regions are areas where the slightly heavier-than-water adhesive
           white perch eggs will find suitable substrate for attachment such
           as shallow streams with overhanging tree branches and fallen
           limbs, or deeper-water areas with firm, sandy bottoms (Lippson
           1973).

           1.A.2. Yellow Perch

                For most of the year, yellow perch range in the low-salinity
           portions of the Chesapeake Bay tributaries. From late February
           to early March, mature yellow perch migrate upstream to the
           spawning grounds at the heads of streams in freshwater. In most
           cases, the spawning grounds mark the upstream limit of yellow
           perch distribution in Chesapeake Bay tributaries (Lippson 1973).
           Yellow perch spawning migrations occur from deep water into
           tributaries when water temperatures reach 7-130 C. Photoperiod,
           rising water temperatures and completion of maturation may
           trigger spawning. The female releases a gelatinous semi-buoyant
           string of eggs near aquatic or inundated vegetation. Rocks,
           sand, and gravel may be used if submerged vegetation is not
           available. Habitat suitability curves for spawning yellow perch
           indicate preferred water velocity is 0.5-2.5 ft/sec; depth is
           from 1.5-3 ft; and substrate consists of mud/soft clay or silt
           (Krieger et al. 1983). Spawning period may be of short duration
           extending for as little as two weeks for the entire spawning run
           (Lippson and Moran 1974).



                                2. METHODS AND MATERIALS

           2.A. Sampling locations

                Sampling for spawning adults was conducted at 21 sites
           located at 10 streams (Table 1, Figure 1). Criteria used to

                                           3









             select tributary streams were similar to Maryland Department of
             Natural Resources (DNR) investigations in which minimum
             conditions are typically set at: depth = one foot, width = 5
             feet, and two miles of perennial flow. Since spawning of the
             target species takes place in freshwater, sites were selected
             which were upstream of obvious brackish water as indicated by
             dominance of salt intolerant riparian vegetation (i.e., cat tail
             Typha sp, tear thumb Polygonum sp). Also, sampling locations
             were selected at road crossings to facilitate access (Figure 1).
             Typically, sites were at or near the head of tide and were from
             approximately 15 to 22 ft in width and approximately 15 to 24 in
             in depth.

                  In order to obtain as broad coverage as possible, stations
             were dropped if it was obvious that anadromous fish did not
             utilize the area (i.e., Rehobeth Branch). Other stations were
             sampled to investigate use and were included for monitoring if
             anadromous species were located (Kings Creek). The numbers of
             larval fish and adult samples collected at each station are
             presented in Table 1.

             2.B. Adult Fish

                  Adult fish were captured using fish traps and electrofisher.
             Fish traps were patterned after those currently used by DNR in
             stream surveys. Traps were constructed of one inch mesh plastic
             wire and were 4 feet long and 18 inches in diameter with an 18
             inch internal funnel at each end. Traps were placed on the
             stream bottom and parallel to the stream current to capture
             upstream migrating fish. The traps were deployed for one 24-hr
             set per week to obtain quantitative samples. The electrofisher
             was a Smith-Root, Inc. back-pack mounted unit powered by a 24 v
             battery. One qualitative electrofishing sample was conducted per
             week to document utilization by anadromous fishes. Anadromous
             and migrating species were identified, counted, sexed, and
             spawning condition checked. Resident species were also
             identified. Water temperature was monitored at University of
             Maryland Eastern Shore (UMES) during spring. When temperatures
             approached 100 C (late February/early March), sampling for adults
             commenced and continued until it was felt that the major spawning
             pulse of the target species was over in mid-May.

             2.C. Eggs and Larvae

                  Ichthyoplankton collections were obtained in conjunction
             with adult sampling. once adults were observed, plankton nets
             were placed in the streams at the locations of adult fish
             sampling. A stationary plankton net was mounted on a 15 inch
             square frame for fixed sampling. The nets were fished for ten
             minute periods. The net was held on the bottom with the mouth
             facing upstream. Data collected during plankton sampling
             included date, time, water temperature, water velocity, and

                                             4









            conductivity.

                 Ichthyoplankton sampling continued concurrently with adult
            sampling. Eggs and larvae were sorted, identified and counted.
            Because of the similarities in the eggs and larvae of alewife and
            blueback herring, discrimination of these species was not
            conducted. It was assumed that the presence of herring eggs
            and/or larvae in the plankton samples indicates spawning of
            either or both species.

                 Numbers of eggs and larvae were calculated according to the
            following formula:
              Number of eggs and larvae in 5 min set      Number/ft3       (1),
               Water Velocity X Area of net opening

            where the water velocity was the arithmetic average of stream
            velocity at the surface bottom and 60% up from the bottom of the
            stream, and the area of the net opening in the water.

            2.D. Water Quality

                 Water samples were collected and analyzed for dissolved
            oxygen, conductivity, temperature, turbidity, pH, alkalinity, and
            hardness. Water samples were collected in conjunction with fish
            sampling. Dissolved oxygen was determined using a Nestler
            Dissolved Oxygen meter. Conductivity was determined using a
            Yellow Springs Instrument (YSI) Model 33 S-C-T meter; temperature
            was determined using the temperature mode on the S-C-T meter; pH
            using an Orion pH meter. Oxygen saturation-values were
            determined using formulae given in Green and Carritt (1967).
            Water velocity was determined using a Marsh McBirney Model 210
            flowmeter. Water velocity was the arithmetic mean of
            measurements determined at the surface, bottom, and at 60% depth
               theoretical maximum velocity (Buchanan 1968]).

                                        3. RESULTS


            3.A. Adult Fish

                 A total of 29 fish species representing 13 families were
            collected in the Somerset  County streams (Table 2). Species
            collected in the trap nets at each site are presented in Table 3
            and those collected by electrofisher are presented in Tables 4
            through 11. Weekly electrofishing sampling commenced in March 4
            and continued through May 17. Anadromous fish species collected
            included alewife, blueback herring, yellow perch and white perch.
            Yellow perch and white perch were the first anadromous species
            collected (March 13 collections) and generally were seen
            throughout the study. River herring were initially collected
            about March 13 and occurred sporadically.

                  From 11 to 23 fish species were collected at each station.
             Streams were divided into two groups relative to the number of
             species collected. A total of 20 to 23 species were collected
             from Somerset Creek, Kings Creek, and Taylor Branch. Also four
             anadromous species (i.e., alewife, blueback herring, white perch
             and yellow perch) were collected at these locations. From 11 to
             13 species were collected from Manokin Branch, Dividing Creek,
             Rehobeth Branch and Marumsco Creek. Except for white perch at
             Manokin Branch, anadromous, species were not collected from the
             latter four locations. A total of 12 species were collected from
             Wicomico Creek at the dam at Eden Allen Dam and the four
             anadromous species of concern. The station was used to obtain
             information of species in the immediate vicinity of the dam and
             no effort was made to obtain a complete species list of the area
             because of its large size.

             3.B. Ichthyoplankton

                  White perch and river herring eggs and larvae were collected
             at stations in which adults were captured. Species, density and
             life stage of fish collected from the 16 ichthyoplankton sampling
             stations are presented in the Appendix. Histograms of abundance
             from Somerset, Taylor Branch and Kings Creek stations that were
             most productive, are presented in Figures 2 through 4. Taylor
             Branch and Kings Creek were the most productive of all stations
             in terms of white perch and river herring spawning according to
             the following summary of Figures 2 through 4 in which maximum
             numbers per sample are presented:

             Kings Creek     2.5        0.018           0.22       0.035


             Ichthyoplanton  sampling along  a longitudinal gradient at Kings
             Creek (Stations 12, 21, 13, 14, and 15) indicated that most
             spawning activity occurred at or just below head of tide and that
             the lower tidal portions were   used as a nursery for the larval
             and juvenile fish (Appendix).


             3.C. Water Quality

             3.C.1. Temperature

                  Water temperature rose throughout the study from less then 8
             C at March 3 to > 25 C April   27 (Figure 5). Temperatures in all
             the investigated streams were   comparable and no temperature

                                               6









            anomalies were detected. Stream temperatures remained greater
            than 10 C (generally considered the temperature of active feeding
            by fishes) after the April 6 sampling period.

            3.C.2. Dissolved Oxygen

                 Dissolved oxygen ranged from 6.2 to 12.4 mg/l throughout all
            the streams (Figure 6). Oxygen saturation curves indicate that
            waters were typically saturated in oxygen (Figure 7). Super-
            saturated conditions occurred at Manokin Branch, Dividing Creek
            and Marumsco Branch.

            3.C.3. Conductivity

                  Conductivity values typically were less than 200 uS/cm at
            all the streams, which indicates the waters at the time of the
            survey were very fresh (Figure 8). The highest conductivities
            encountered were at Somerset Creek 320 uS/cm, when it was noted
            that the tide was exceptionally high and water was running
            upstream because of it. Also, the consistently low conductivity
            values indicate no anomalies in the source of the stream waters
            such as ground water input from high conductivity aquifers.

            3.C.4 Water Velocity

                 Water velocity typically was less than 1 ft/s (Figure 9).
            Velocity less than 0.2 ft/s was associated with supersaturated
            oxygen levels at Manokin Branch, Rehobeth Branch, and Dividing
            Creek (Figure 7).

            3.C.5 pH

                 pH was typically low, with only one (Taylor Branch) greater
            than 7.0 (Figure 10). One sample from Dividing Creek was
            determined to be 4.5. This sample (April 11) was associated with
            a rain event as indicated by the high water velocity at that
            date. The pH may have been depressed through runoff from the
            rain event.



                                     4.0 Discussion


                 Data collected during the fish survey indicates that most
            stream within Somerset County support a fish fauna indicative of
            healthy stream conditions. The presence of anadromous fishes
            should be viewed that stream quality is good and should be
            maintained. Streams that did not support anadromous species such
            a's Rehobeth, Marumsco and Manokin were observed to be located in
            intensely cultivated watersheds. Problems viewed at the stream
            were associated with channelization, and siltation due to runoff
            from agricultural fields near areas with no stream buffers. The

                                            7









            continued presence of anadromous species such as yellow perch and
            river herring should continue to be used as an indicator of steam
            quality. There is relatively "large" population of river herring
            that are prevented from upstream access at the dam at Edan Allen
            Road. Some thought should be given to the possibility of
            installing a fish ladder at the dam to afford access to fish to
            the upper portion of Wicomico Creek.

                 Fishes such as banded sunfish, mud sunfish and bluespotted
            sunfish were found in a variety of locations (i.e., Rehobeth
            Branch, Manokin Branch, Dividing Creek, Kings Creek). The
            distribution of these fishes is resticted to generally small, low
            gradient streams that drain swampy areas and therefore have low
            pH. Low pH values were observed in streams draining Dividing
            Creek. These streams drain swamps where the buildup of organic
            acids can be quite high naturally.

                 It has been our observation that streams in the upper
            watershed require good riparian buffers to protect lower sections
            of the stream from impacts due to agriculture. The impacts remain
            even if the lower sections do have significant buffers. It
            appears that streams with buffers of 25 to 50 ft were of
            significantly higher quality than streams without any buffer. It
            is our recommendation that further study be conducted on stream
            riparian zone relationship in the streams of Somerset County. At
            the very least good stream buffers (25 to 50 ft wide) should be
            maintained along all streams.

                                     FINAL REPORVADMINISTRATION OF THE
                              ANADROMOUS FISH SURVEY, SOMERSET COUNTY, MARYLAND
                                                  SPRING 1990



                     Somerset County, Maryland signed an agreement with the University of
                Maryland - Eastern Shore in March 1990 to inventory streams within Somerset
                to determine use by spawning migratory species.       This study was funded by
                the Coastal Resources Division, Maryland Department of Natural Resources,
                through a CZM grant.

                     The University's initial proposal included the services of Roman V.
                Jesien, a     fisheries scientist connected currently with Horn            Point
                Environmental Laboratory, Thomas S., Hopkins, Professor of biology and
                Clement L. Counts, III, Director of UMES' Coastal Ecology Research
                Laboratory.    After some discussion and modifications, this proposal became
                the basis for the present survey.

                     The UMES team began visiting sites and talking with property owners
                and fishermen even before the contract was finalized.            As previously
                reported, sampling began March 4, 1990 determined by field conditions.
                Decision as to final sampling stations were altered and moved downstream
                based on observation.    The team had conducted longitudinal transects.along
                streams to determine spawning limits and nursery areas.        A decision was
                also made to focus more on ichthyoplankton than originally planned.
                Collection then continued until it became clear that the major spawning
                pulse of the targeted species had occurred.

                     A no-cost extension was received for the project       due to front-end
                delay in    water sampling and additional time needed for ichthyoplankton
                analysis.   A draft report was submitted to CRD in mid-November.

                     Upon   word that DNR fisheries found methods and procedures outlined in
                the draft report in keeping with their standards, the Department of
                Technical   and Community Services scheduled a final meeting with UKES
                professors  and Dr. Jesien. Suggestion was made to provide the County with
                more site specific information on sites inside and outside the Critical
                Area as well as any management information which could form part of a
                recommendation.


                     The completed report will be presented to the Planning Commission and
                the  County Commissioners with a recommendation that surveyed areas outside
                the  Chesapeake Bay Critical Area which offered suitable fish habitat
                receive the similar protections as those afforded anadromous fish streams
                in the CBCA. These include linitations on the use of concrete or riprap on
                stream beds, construction activities prohibited during the spawning period
                (March 1      June 15) in stream buffers and channelization or blockage of
                streams.

                      Consideration    will   also be given to general stream            buffers,
                 particularly in heavily farmed areas.     The consultants indicated a 25 foot
                 vegetated buffer should be adequate in the absence of steep slopes.
                 Although no major problems seem to exist on the streams tested, an area in
                 the central part of the County shows signs of degradation due to run-off
                 from farm fields.


                      Reduction in soil erosion along these banks may be sufficient to bring
                 anadromous fish into these streams in the future.


                      Any regulations introduced would take the form of special provisions
                 to the Somerset County Zoning Ordinance.

                      Some kind of follow up to this survey should be considered since such
                 a report provides only a "snap shot" of the 1990 spawning season. A wetter
                 or drier year, for example, could lead to different results. Somerset
                 County should, ideally, plan for a second study in the future.          In the
                 interim, local school groups and/or the University should be approached to
                 monitor streams for water quality and record keeping should be coordinated.
