Recognition of the need for a more holistic, ecosystem approach to the assessment and management of living marine resources has renewed interest in quantitative community eco logy and fueled efforts to develop ecosystem metrics to gain insight into system status. This investigation utilized 12 years (2008 to 2019) of fisheries-independent bottom trawl survey data to quantify and synthesize the spatiotemporal patterns of species assemblages inhabiting the nearshore Mid-Atlantic Bight (MAB). Assemblages were delineated by ecomorphotype (EMT), and all species collected by the survey were allocated among 9 EMTs: demersal fishes; pelagic fishes; flatfishes; skates; rays; dogfishes; other sharks; cephalopods; and …

The continental shelf of the United States was once the preserve of commercial fishermen. This is no longer the case. The exclusive economic zone is increasingly becoming the focus of other economically powerful, sometimes incompatible uses, including green energy, shipping, communications, mining, military exclusion zones, and conservation regions. These other uses generally have fixed boundaries. The distribution of fished species moves in relation to warming of shelf waters, presenting challenges to both federal regional fishery management councils and industry alike. There is need for continued engagement between user groups with respectful use of guiding science and legal structure to ensure …
Comparisons Of Mean Length-Based Mortality Estimators And Age-Structured Models For Six Southeastern Us Stocks, Quang C. Huynh, Nancie J. Cummings, John M. Hoenig
Comparisons Of Mean Length-Based Mortality Estimators And Age-Structured Models For Six Southeastern Us Stocks, Quang C. Huynh, Nancie J. Cummings, John M. Hoenig

Length-based mortality estimators have been developed as alternative assessment methods for data-limited stocks. We compared mortality estimates from three methodologically related mean length-based methods to those from an age-structured model (ASM). We estimated fishing mortality and determined overfishing status, i.e. if F/FMSY > 1, for six stocks which support important recreational and commercial fisheries in the southeastern United States. The similarities in historical fishing mortality between the length-based methods and the most recent assessments varied among the case studies, but the classification of overfishing status in the terminal year did not differ based on the choice of model …

Fishing skillis perceived to play a crucial role in catching fish. The
question arises for fishery managers as to whether or not there are observable
and measurable attributes of the skipper or vessel hat can be monitored and
regulated to account for skipper skill and, hence,this source of fishing capacity.
Equating technical efficiency with skipper skill, this paper evaluates technical
efficiency and skipper skill in the Kedah, Malaysia,trawl fishery to address this
issue.
