Description
Summary:No abstracts are to be cited without prior reference to the author.The status of the spiny dogfish (Squalus acanthias) stock in the US portion of the Northwest Atlantic has become a contentious issue. Distributed from Maine to Florida, this species was once considered to be the most abundant shark throughout its US range. As a result of reported declines below biomass threshold levels, in early 2000 the Mid-Atlantic, New England Fishery Management Councils, and Atlantic States Marine Fisheries Commission implemented a management plan which imposed annual quotas and possession limits for vessels fishing in both Federal and State waters. Because of characteristics such as slow growth, extended gestation period, small litter size, and a spawning-stock biomass (SSB) below threshold levels as recent as 2005, the spiny dogfish population was not anticipated to rebound for more than a decade. Recent Northeast Fishery Science Center (NEFSC) survey data, however, suggest a fourfold increase in SSB has occurred ...
