Estimating Relative Abundance Of Young Of Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay (Spring 2007), Troy D. Tuckey

Reports

The Atlantic States Marine Fisheries Commission (ASMFC) adopted the Interstate Fishery Management Plan (FMP) for the American eel in November 1999. The FMP focuses on increasing coastal states’ efforts to collect American eel data through both fishery dependent and fishery independent studies. Consequently, member jurisdictions (including Virginia) agreed to implement an annual survey for YOY American eels. The survey is intended to “…characterize trends in annual recruitment of the YOY eels over time [to produce a] qualitative appraisal of the annual recruitment of American eel to the U.S. Atlantic Coast” (ASMFC, 2000). The development of these surveys began in 2000 …

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2007 Annual Report, John E. Olney, Brian Watkins

Reports

Concern about the decline in landings of American shad (Alosa sapidissima) along the Atlantic coast prompted the development of an interstate fisheries management plan (FMP) under the auspices of the Atlantic States Marine Fisheries Management Program (ASMFC 1999). Legislation enables imposition of federal sanctions on fishing in those states that fail to comply with the FMP. To be in compliance, coastal states are required to implement and maintain fishery-dependent and fishery-independent monitoring programs as specified by the FMP. For Virginia, these requirements include spawning stock assessments, the collection of biological data on the spawning run (e.g., age-structure, sex ratio, and …

Reports

Harvests of American eel along the U.S. Atlantic Coast have declined in recent years, and similar patterns have been noted in the Canadian Maritime Provinces as well as in Europe with its congener, A. anguilla (Ciccotti et al., 4 1995). Fishery independent indices of abundance have also shown a decline in American eel populations in recent years (Richkus and Whalen, 1999; Geer, 2003; Montane and Fabrizio, 2006). Possible explanations for this decline include Gulf Stream shifts, pollution, overfishing, parasites, and barriers to fish passage (Castonguay et al., 1994; Haro et al., 2000). In addition, local factors such as unfavorable wind-driven …

Reports

Fisheries management techniques are not often applied to American eels because basic biological information is not well known. Unknown biological parameters such as variation in growth rates and length at age have complicated stock assessment and management efforts. Though American eel are not usually considered a sport fish, their ubiquity and readiness to take a bait leads them to be caught by recreational fishermen (Collette and Klein-MacPhee, 2002). Young American eel are also used as a baitfish in coastal areas (Jenkins and 4 Burkhead, 1993.) Absence of basic population dynamics data has hampered attempts at evaluation of regional exploitation rates …

Reports

Internal anchor tags with external tubes were used to tag 1,986 striped bass in the James River in the Spring of 1987. The total number tagged was adjusted (at this time) to 823 because of observed and suspected tagging mortality. The available stock of striped bass in the Spring contained both young resident fish and mature nonresident fish which left the area of capture after spawning, presumably to migrate north in coastal waters. The exodus of the mature fish after spawning and the absence of a commercial fishery resulted in only 42 tag returns as of Spring 1988. This proportion …
