Abstract:: Several factors currently threaten blue crab (Callinectes sapidus) in the Chesapeake Bay. In addition to poor water quality, degraded habitat, and shifting environmental conditions, derelict gear has recently been recognized as a significant source of mortality for this economically and culturally significant species. From 2008 through 2014, commercial watermen in...

Abstract:: We empirically disentangle the efficiency mechanism of revenue sharing, in which a group of harvesters shares catch and/or revenue among members of a fishery cooperative, by incorporating the influence of social capital. In addition to each of revenue sharing and social capital influencing a fishery independently we hypothesize social capital...

Some of the reasons are: an increase in demand from China, the distance of these fisheries to China, and the high rate of fisheries development. Most sea cucumber fisheries are small-scale with a simple management system. To overcome overexploitation,...

Abstract:: The Baltic fishery is managed under the European Union Common Fisheries Policy (CFP) which defines procedures for setting annual total allowable catches (TAC) for major commercially harvested species. TACs are given as fixed shares to each member state by applying the principal of relative stability. Poland uses non-tradable individual vessel...

Abstract:: Management objectives of vulnerable fish species must focus on maintaining healthy population status. Hence, reference points should be constrained to ensure recruitment. We assessed bioeconomic reference points for the totoaba (Totoaba macdonaldi), an endemic fish to the Gulf of California, reaching lengths of 2 m and 25 years. Totoaba fishing...

Abstract:: Informal fisheries (including unreported legal, illegal and discarded catch) have significant benefits for communities that official statistics often ignore, yet there is an associated loss in potential economic impacts compared to catch that is processed and marketed formally. This represents a significant global issue, as recent estimates suggest that about...
