The Sustainable Fisheries Act of 1996 and the amended Magnuson-Stevens Fishery Conservation and Management Act elevated habitat and conservation as priorities in federal fisheries management. In particular, the Essential Fish Habitat (EFH) amendment to the Magnuson-Stevens Fishery Conservation and Management Act establishes guidelines to assist fishery managers in the description and identifica...

The inability of fishers to avoid bycatch when operating in a multispecies fishery can create problems when the bycatch species itself is the subject of conservation-based controls. Increased protection of the bycatch species can only be achieved through a reduction in the overall catch of the fishery. Such a problem has arisen in the Australian south east fishery where the stock of one bycatch...

As well as serving valuable biodiversity conservation roles, functioning no-take fishery reserves protect a portion of the fishery stock as insurance against future over-fishing. So long as there is adequate compliance by the fishing community, it is likely that they will also sustain and even enhance fishery yields in the surrounding area. However, there are significant gaps in scientific know...

Perhaps the most fundamental insight from fishery science is that ecosystems impose important and predictable constraints on food production from the sea. The familiar hump-shaped growth curve implies that the growth rate and carrying capacity of a species limit its production: Once stocks are depleted, further increasing fishing pressure will only lead to decreases in catch. This logic underpi...

The Goliath grouper, Epinephelus itajara, a large-bodied (approximately 2.5 m TL, > 400 kg) and critically endangered fish (Epinephelidae), is highly vulnerable to overfishing. Although protected from fishing in many countries, its exploitation in Mexico is unregulated; a situation that puts its populations at risk. Fishery records of E. itajara are scarce, which prevents determination of its f...

TAC, total allowable catch, is always setting to be the goal of fishery management. No matter what TAC is taken to be the goal of fishery management, some fundamental limitation of TAC is required. Generally, dome shape is used to express the relationships between the biomass and net production. There is unique point of biomass having the maximum net production (BMNP). This paper attempts to sh...

The Pacific Coast groundfish fishery is conducted along the entire coastline of Washington, Oregon, and California, and includes a diverse range of habitats, species, and participants. The Pacific Fishery Management Council’s (PFMC) Groundfish Fishery Management Plan (FMP) contains more than 90 species organized into several sub-fisheries, including 1) the Dover sole, thornyheads, and sablefish...

A coastal fishery brings high productivity and economic profit while supporting cultural norms. However, it also causes environmental degradation and political conflicts, which sometimes collapse a fishery. With the current global shift from capture fisheries to aquaculture, appropriate management is required for social and environmental sustainability. To identify essential factors in coastal ...

North Carolina’s Blue Crab Fishery As North Carolina’s number one fishery, blue crabs, Callinectes sapidus, are part of an important industry for numerous coastal communities. The fishery supports commercial fishermen, dealers, gear providers and processors throughout the year. Fluctuations in landings have led to concerns over crab populations and the livelihood of the commercial crabbers they...

Time series datasets are widely used in many areas. When the size of a dataset grows large or the number of datasets increases, it becomes difficult for a human to observe the structure of a dataset or to understand the underlying relationships. In this report, we present an interactive visualization tool called Fishery View to display and interact with fish population data obtained from the UB...
