Bycatch of Marine Mammals in U.S. and Global Fisheries

Conservation Biology, 2006
Abstract:  Fisheries bycatch poses a significant threat to many populations of marine mammals, but there are few published estimates of the magnitude of these catches. We estimated marine mammal bycatch in U.S.

Cyclical harvesting in fisheries with bycatch

Resource and Energy Economics, 2015
Abstract Bycatch is often a concern in sustainable fisheries management due to its contribution to overfishing problems. This paper examines bycatch in a multi-sector fishery in which the gear of one sector is imperfectly selective while in the other it is perfectly selective. In the model, the two stocks are biologically independent so the fisheries

Standards for the effective management of fisheries bycatch

Marine Policy, 2014
Abstract Mitigating the environmental impact of commercial fishing, by avoiding, minimizing and compensating for adverse effects, is core business for fisheries management authorities globally. The complex interplay of ecological, economic, and social considerations has often resulted in bycatch management being reactive, confrontational and costly ...

Ingredients for Addressing the Challenges of Fisheries Bycatch

Bulletin of Marine Science, 2011
Minimizing fisheries bycatch, the incidental capture of non-target species, is a global environmental challenge. In many regions, bycatch of imperiled species is one of a number of issues that threatens species viability and impedes the development of sustainable fisheries. effectively addressing bycatch of species of conservation concern and improving

Bycatch and discards of the Kuwait shrimp fishery

Fisheries Research, 2000
Abstract The landings and survey data for the Kuwait shrimp fishery were analyzed. The estimated bycatch-to-shrimp ratios exhibited a seasonal pattern, with summer having the highest ratio. There was a significant difference in bycatch-to-shrimp ratio between Kuwait Bay and the rest of the Kuwaiti waters.

Sustainability of fishery bycatch: a process for assessing highly diverse and numerous bycatch

Environmental Conservation, 2001
In tropical prawn (shrimp) trawl fisheries it is daunting to assess the sustainability of bycatch species because they are diverse and there is little historical and biological information for quantitative stock assessments. We developed a process to examine the likely impact of prawn trawling on the sustainability of bycatch species and applied this ...

Healthy fisheries can reduce bycatch

Science, 2018
Fisheries Bycatch of marine mammals, turtles, and birds during commercial fishing is a considerable threat. Activities intended to reduce bycatch are often thought to conflict with commercial fishing. However, Burgess et al. show that in the majority of cases, managing fishery stocks to best promote long-term sustainability would also reduce bycatch ...
