The current state of many freshwater fish stocks worldwide is largely unknown but suspected to be vulnerable to exploitation from recreational fisheries and habitat degradation. Both these factors, combined with complex ecological dynamics and the diffuse nature of inland fisheries could lead to an invisible collapse: the drastic decline in fish stocks without great public or management awarene...
Background During the past few decades several international initiatives have been adopted to promote the implementation of an Ecosystem Approach to Fisheries Management (EAFM). The 1995 FAO Code of Conduct for Responsible Fisheries has been developed as a reference framework for sustainable fisheries addressing ecosystem considerations, principles and goals needed for EAFM (Garcia & Cochrane, ...
There is great variation in discarding practice among fisheries in different parts of the world. Management systems result in some fisheries discarding mostly fish offal, much of which is macerated into small chunks, while other fisheries discard large (ca. 25 cm) whole fish. Scavenging seabirds consume high proportions of most categories of discarded fish and offal (typically 60 to 80% of disc...
IN THEIR REPORT “EFFECTS OF MARINE reserves on adjacent fisheries” (30 Nov., p. 1920), C. M. Roberts and co-authors present data indicating that fishery yields have increased in waters adjacent to marine reserves in St. Lucia and east Florida. In many developing island nations like St. Lucia in the Caribbean, fisheries are seriously overexploited, and little or no fisheries management exists. I...
BACKGROUND Ecosystem modeling applied to fisheries remains hampered by a lack of local information. Fishers' knowledge could fill this gap, improving participation in and the management of fisheries. METHODOLOGY The same fishing area was modeled using two approaches: based on fishers' knowledge and based on scientific information. For the former, the data was collected by interviews through t...
The Gulf of Alaska and Bering Sea Aleutian Islands groundfish fisheries have been managed under fishery management plans since 1978 and 1981, respectively. The range of the Steller sea lion overlaps the waters where the fisheries are conducted. Under the Endangered Species Act, Steller sea lion west of Cape Suckling, Alaska, are listed as endangered; east of Cape Suckling they are listed as thr...
