Climate change may cause significant changes in the distribution, abundance, and species mix of commercial fishery resources. In any given area stocks of some species may decline; stocks of other species may increase; and new species may appear in commercially significant volumes. However, it is difficult to predict what specific...
A scientific knowledge gap exists with regard to how benthic habitat is affected by destructive fishing methods, such as bottom trawling, and how this impacts upon the productivity of commercial fish stocks. This
article addresses analytically the effects of destructive fishing practices of a single gear fishery on a non-renewable...
Fishing activities within the Galapagos Marine Reserve (GMR) are restricted to small-scale levels by national law. The fishing sector has relied on just two fisheries, sea cucumber and spiny lobster, and a
strong Asian export market. Despite a series of input and output controls and a co-management scheme, stocks have...
Spiny lobster (Panulirus argus) and related species represent one of the most important commercial fisheries targeted within the Gulf of Mexico and Caribbean regions. This important fishery extends from Florida (USA) to Brazil. The longlived, pelagic larval stage within the life cycle of spiny lobster reveal this species to be...
NOAA’s National Marine Fisheries Service (NMFS) recently completed two reports on excess harvesting capacity, National Assessment of Excess Harvesting Capacity in Federally Managed Commercial Fisheries and Excess Harvesting Capacity in U.S. Fisheries: A Report to Congress. This paper presents the definitions of harvesting capacity, excess capacity, and overcapacity used in...
A model for studying how destructive fishing practices may affect commercial fish stocks through their effect on habitat is presented. It may be used both for renewable habitat-types, like eelgrass (Zostra marina) or sponges, and also practically non-renewable habitats like corals. The model demonstrates the trade-offs between using destructive and...
Environmental concerns about seafood consumption generally are associated with the status of target stocks as well as bycatch and/or habitat issues. The more recent concept of "food miles" hails from terrestrial food production, and focuses on "consuming locally" in an effort to reduce the carbon footprint of a consumer's diet....
The aim of this paper was to compare the nutritional value of some low price fish (Sardina pilchardus, Engraulis encrasicholus, Anguilla anguilla, Salmo trutta, Mugil chepalus) to high price fish with high consumption rate (Sparus aurata, Merluccius merluccius, Dicentrarchus labrax).In general, the commercial values of several fish species in Greece...
Molluscan shellfish culture is an important component of the commercial aquaculture industry in Florida, USA. The primary species cultured is the hard clam, Mercenaria mercenaria. Currently, annual grower revenues total approximately $15 million, which generate $40 million in economic impact to the state. However, hard clam production in other USA...
Fisheries exploited under open-access conditions create externalities, resulting in a range of problems associated with over-capitalisation and stock depletion. One answer to this is to shift the mode of production away from hunting and towards husbandry, an approach which becomes feasible where some control can be exercised over the resource...
