Abstract:Manual survey data was collected to measure striped bass distribution in Plum Island Estuary during the time period that they are in New England during their summer foraging migration. Acoustic telemetry was used to tag and track individual fish and provide measures of abundance at sample sites distributed throughout the estuary.

Methods:TAGGING
The distribution of 50 striped bass (mean total length = 510 48 mm; range = 403 to 597 mm) was quantified with VEMCO V13-R64k coded acoustic transmitters (frequency of 69 kHz, a ping rate of 60 to180 s, estimated tag life of one year). Striped bass were caught via hook-and-line on June 17-18, 2009 (N = 30) and June 29 (N = 20). Using clove oil as the anesthetic (1.5 L of clove oil/L of water; mean application time = 8.9 min, SE = 1.1 min; Cooke et al. 2004, Pautzke et al. 2010), fish were first weighed (g) and measured (TL, mm). Tags were then surgically implanted (Bridger and Booth 2003) using a sterile scalpel to make a 23-cm incision 2 cm above the ventral midline and approximately 1.5 cm behind the pelvic fin. Through this opening, a transmitter was inserted into the peritoneal cavity and the incision was closed with three stitches using sterile dissolvable sutures (Ethicon Monocryl violet monofilament suture with 3/8 curved cutting needle). After tagging, each striped bass was injected with oxytetracycline (0.1 mg/kg of fish; Liquamycin; Pfizer, New York; Callahan 2009) and placed in a recovery tank filled with ambient temperature estuary water until the fish swam upright (mean recovery time = 21.3 min; SE = 1.2 min). All tagged fish were released upon recovery at the approximate site of capture.

MANUAL SURVEY
A VEMCO VR100 tracking receiver with a VH-165 omni-directional hydrophone was used to manually survey tagged fish at forty sample sites once a month from July-October, 2009. The sites were chosen to cover all regions and habitats of the estuary. For one week each month (July-October, 2009), with the hydrophone about 0.5 m below the boat, fish detections were recorded for 15 min at each site. All 40 sites were visited on both an ebbing and a flooding tide each month. Sites were divided into five groups and the order of visitation for each group was randomized for each survey. All sites were visited within six days.
