, ,- HAZLETON ENVIRONMENTAL SCIENCES 1979 Hudson River Shortnose Sturaeon Studv Scope of Work I. Objective To determine the relative importance of the Stuyvesant area to the life history of the shortnose sturgeon in the Hudson River estuary.

II. Introduction A study of the Shortnose Sturgeon population will be conducted from river mile (RM) 153 (Troy Dam) through RM65 (Roeston). See Appendix A, Hudson River Navigational Charts. The study program was designed in cooperation with Mr. William Dovel of the Oceanic Society, Stanford, Connecticut, who has been studying the Hudson River Shortnose Sturgeon population in recent years. A Three Phase Program was jointly developed to integrate our studies to provide a comparable data base and minimize duplication of effort between study areas. Phase I will document the distribu-tion of spawning adults, Phase II will document the distribution of early life stages (eggs and larvae) and Phase III will document the distribution of voung-of-the-year Shortnose Sturgeon within the study area. A concerted effort will be made to cample at the proposed Station's intake location. This location will be fished with each type of collection gear at least once during each sampling week. ,

The sampling program to be implemented in Phase I will encom-pass a 47 mile extent of the Hudson River (RM 153 through 106).

, . HAZLETON ENVIRONMENTAL SCIENCES liazleton Environmental Sciences will sample from the Troy Dam to an area approximately 6 miles downriver of the Stuyvesant Site. The Oceanics Society will sample the area immediately below the Hazleton Environmental Sciences' study area.

Drift gill netting will be conducted with 450ft by 8ft experimental mesh gill nets. Each net will consist of alternating panels of 2, 2.5, and 3in bar mesh. During periods of slack tide, nets will be floated perpendicular to shore near the channel bottom.

Nets will be fished four days per week for three weeks beginning on 23 April. Sampling will be initiated north of the site during each sampling week. In general, 2-4 drifts will be conducted during each sampling day at approximately 2 mile intervals for 15 minute duration each. A different segment of the river starting six miles north of the Stuyvesant Site and extending to six miles south of the Site will be sampled during each of three days. On the fourth day,campling will occur at any of the areas requiring additional effort and/or the area near Troy Dam. In addition, 100ft by 6ft gill nets consisting of 2.0, 2.5, 3.0 and 3. Sin bar mesh will be set parallel to shore overnight at Locatic ns 13, 21, 23, 41, 43 and 63 (Figure 1), and 12 additional locations distributed evenly between river segments north and south of the Site. Both sides of the river will be sampled. Six locations will be sampled per day and will provide data comparable to 1977 and 1 gill net data. A' i f

HAZLETON ENVIRONMENTAL SCIENCES locations will be delineated on Hudson River navigational charts.

Sturgeon will be measured for length and weight. Thene measure-ments and spawning condition as determined by extern.1 examination will be recorded. Sturgeon larger than 10in totrl length will ne tagged and all sturgeon will be released at the location of capture.

Tag number and location of capture will be recorded.

B. Phase _II - Documentation of Distribution of Early Life Stages (Engs and Larvae)

The sampling program to be implemented in Phase II will.encom-pass an approximate 88 mile extent of the Hudsor River (RM 153 through 65) . Phase II will be initiated following the documentation of sturgeon spawning and will probably start during the week of 15 Ma . The duration of sampling will be four days per week for approx .. ;ely 2 to 3 weeks. .

Collections will be made using 1.0m dia5.eter Hensen nets of 10 Nitex mesh attached to an epibenthic sled. During the day and at approximately one mile intervals, single three-minuta tows will be taken in the river channel against the current. Occasional side channel samples will be taken to document ure of nearshore habitats. Approximately 20 miles of river and 35 tows will be made each day. The volume of water sampled will be determined for each sample with a net-mounted General Oceanics flow metar. Each week of sampling will commence at the southern extent of the study area and progress northward.

Samples will be sorted and the sturgeon identified and rcoasured immediately after collection. Identification will be aided by use 4

HAZLETON ENVIRONMENTAL GCIENCCG of dissecting microscopes and macroscopes on board the research vessel. Every attempt will be made to return the larvae and young-of-the-year sturgeon alive to the river at the locations captured.

Water depth and temperature will be recorded at each sampling location. Ponar grab samples will be taken at locations where sturgeon are collected to determine substrate type. Sampling loca-tions will be lineated on Hudson River navigational charts.

C. Phase III - Documentation of the Distribution of Young-of-tho-Year Shortnose Sturceon The sampling program to be implemented during Phase III will cover the same sampling area as Phase II. Each week of sampling will commence at the southern extent of the study area and progress northward. Phase III will commence when the shortnose sturgeon larvae collected in Phase II attain 20-30mm in total length.

Trat ling techniques will be implemented in Phase III to minimize the stress and avoidance of y-o-y sturgeon associated with the use of Hensen nets. The duration of sampling will be for 2 to 3 weeku which may be non-consecutive. Each sampling week will consist of four days.

Bottom trawling will be conducted with a 21ft headrope, 26ft foot rope trawl with a 1/2in stretch codend liner. During the day and at approximately one mile intervals, single five-minute tows will be conducted with the current primarily in channel areas.

Approximately 20 miles of river and 25 town will be made each day.

During periods of slack tide, experimental gill nets (200ft by 8ft) consisting of 0.5in bar mesh will be drifted perpendicular s

452 141

HAZLETON ENVIRONMENTAL SCIENCES to shore; along the channel bottom. 'If successful, approximately 2-4 drifts will be conducted during cach sampling day for a duration of approximately 15 minutes.

Samples will be sorted and the sturgeon identified and measured immediately after collection. Identifications will be aided by use of dissecting microscopes and macroscopes on board the research vessel. Every attempt will be made to return the sturgeon alive to the river at the location captured.

Water depth and temperature will be recorded at each sampling location. Ponar grab samples will be taken at locations where sturgeon are collected to determine substrate type. Sampling locaticus will be delineated on Hudson River navigational charts.

IV. Reports A final report will be submitted to UE&C and NYSE&G that will:

1) describe all field and analytical methods; 2) present and discuss results; and 3) make comparisons with data collected by the Oceanic Society and earlier years of study at the Stuyvesant Site. A copy of all field data will be submitted to the New York. State Depart-ment of Environmental Conservation at the completion of each study phase.
