Management of the Mediterranean demersal stocks has proven challenging mainly due to the multi-species character of the fisheries. In the present work, we focus on the multi-species demersal fisheries of the Aegean Sea (eastern Mediterranean) aiming to study the effects of different management measures on the main commercial stocks, as well as to explore the economic viability of the fisheries ...
Marine Protected Areas (MPAs) have been widely proposed as a fisheries management tool in addition to their conservation purposes. Despite this, few studies have satisfactorily assessed the dynamics of fishers' adaptations to the loss of fishing grounds. Here we used data from before, during and after the implementation of the management plan of a temperate Atlantic multiple-use MPA to examine ...
Background Bangladesh is basically a low lying flat land country, is endowed with enormous inland fishery resources which contribute a significant part of freshwater fish production. Inland fisheries in Bangladesh contain different types of water bodies’ character e.g. flowing rivers, beel—usually deeper depression in the floodplain, haor—extensive low lying areas comprising several perennial b...
Bycatch is an old fisheries problem, but a relatively new topic in fisheries management. The increased awareness is often credited to the growth of conservation movements, but also a more recent understanding – especially by the industry that marine resources are exhaustible, and that worldwide fishing efforts are excessive and threatening to marine stocks. The issue of bycatch and discards has...
This paper uses GIS and spatiotemporal analysis of a historically and culturally modified marine ecosystem to evaluate Pacific herring abundance, declines, vulnerabilities, and future prospects, about which a Native Tribe and state fisheries managers disagree. In 2008, the Sitka Tribe of Alaska (STA) requested that an area within its traditional waters be closed to commercial sac roe fishing to...
Recent work suggesting that fisheries depletions have turned the corner is misplaced because analysis was based largely on fisheries from better-managed developed-world fisheries. Some indicators of status show improvements in the minority of fisheries subjected to formal assessment. Other indicators, such as trophic level and catch time series, have been controversial. Nevertheless, several de...
Marine reserves are areas of the sea where fishing is not allowed. They provide refuges where populations of exploited species can recover and habitats modified by fishing can regenerate. In some places, closed areas have been used for fisheries management for centuries [1] and, until recently, natural refugia also existed, inaccessible through depth, distance or adverse conditions. Development...
This chapter presents the history of Norwegian fisheries management since 1900, focusing on the system for implementing resource conservation goals. It describes how the Norwegian implementation system has developed incrementally in response to new implementation challenges and outlines in detail the system for handling the most difficult legal and administrative issues in TAC-based management....
Inland fisheries are a vital component in the livelihoods and food security of people throughout the world, as well as contributing huge recreational and economic benefits. These valuable assets are jeopardized by lack of research-based understanding of the impacts of fisheries on inland ecosystems, and similarly the impact of human activities associated with inland waters on fisheries and aqua...
During the past 12 years fishery managers responsible for federal fisheries off Alaska have developed and implemented three new fishery management limited access/quota share programs in place of traditional open access management. The three limited access programs are unique but each provides for the allocation of quota shares to individual participants in the halibut and sablefish longline fis...
