Female spiny dogfish experienced high fishing pressure on the US east coast during the 1990’s. This led to a skewed population sex-ratio of 7 males per female which later declined to 4:1 as the stock was rebuilt. The current fishery still targets m

This study examines the potential uncertainty in survey biomass estimates of Spiny Dogfish Squalus acanthias in the Northeast U.S. Continental Shelf Large Marine Ecosystem (NES LME). Diel catch-per-unit-effort (CPUE) estimates are examined from the N

A difficult question often confronting fisheries assessment scientists and managers is whether or not to accept that a shift in stock productivity has occurred. This is particularly the case when a stock has remained at historically low biomass despi

Marine ecosystems are characterized by many complex interactions. Fisheries managers face the challenge of maintaining or restoring sustainability for individual living resources which are affected by both ecological and economic interactions with ot

Depletion experiments are conducted to estimate efficiency of sampling gear and density of organisms. Traditional models for analyzing these experiments make restrictive assumptions that are often violated. We present a new spatial model, suitable fo

Biomass and commercial catch rates of Atlantic sea scallops Placopecten magellanicus in the USA generally declined from the 1960s through the mid-1990s as fishing mortality increased. Sporadic large recruitment events temporarily increased landings b

We evaluated the spatial distribution of otter trawl fishing effort and catches resulting from the imposition in 1994 of year-round and seasonal groundfish closed areas off the NE USA. Vessel locations were available from logbooks, vessel monitoring

In this paper, we concentrate on spatial aspects of growth and reproduction for sea scallops (Placopecten magellanicus) to advance the general theory for development of reference points for sessile animals and to illustrate the general points with se

Parametric relationships of recruitment to an index of parental stock size assume the latter is proportionally related to spawning potential, irrespective of the demographic composition of adults. Recent empirical information, however, suggests that
