~ oastal zone management (CZM), ~ a multidisciplinary activity par excellence. involves branches of the natural and social sciences in which the concept of overfishing has no operational meaning. Thus, fishery biologists working alongside representatives of other disciplines are often hard-pressed to define this concept, which is of crucial importance to fishery management. This essay is an att...

In the U.S. West Coast groundfish bottom trawl fishery, Pacific halibut (Hippoglossus stenolepis) bycatch can impact some fishers’ ability to fully utilize their quota shares of groundfishes. this study, we compared catch efficiency for and four commercially important species between an illuminated non-illuminated trawl. The caught significantly fewer sablefish than For Dover sole (Microstomus ...

The US Pacific Coast has been largely free of fishery collapses that have occurred elsewhere, but the situation appears to be changing. Here, we show results from the first systematic study of demersal fishes along the US Pacific Coast. Using data from a quarter-century long, fishery-independent, coast-wide trawl survey, we document fundamental shifts in the demersal fish assemblage along the U...

The shrimp fishery is the most economically important fishery in Mexico. The trawler-based portion of this fishery results in high rates of by-catch. This study quantifies and describes the biodiversity of by-catch associated with trawling in the Bahía de Kino region of Sonora, Mexico. Data were collected from 55 trawls, on six boats, over 14 nights, during November of 2003, 2004, 2006-2009. By...

The increase of anthropogenic pressures on the marine environment together with the necessity of a sustainable management of marine living resources have underlined the need to map and model coastal environments, particularly for the purposes of spatial planning and for the implementation of integrated ecosystem-based management approach. The present study compares outputs of a process-driven b...

Two surveys were carried out in the Ross Sea region during February and March 2004 and 2008 from the New Zealand RV Tangaroa. Fishes were sampled on the continental shelf and slope of the Ross Sea, and on adjacent seamounts to the north, mainly using a large demersal fish trawl and a large mesopelagic fish trawl. Parts of the shelf and slope were stratified by depth and at least three random de...

• Trawlers are profit-oriented, and increasing fishing revenue is a more important business objective than minimizing risk. The seasonal migration of North-east Arctic cod determines the dynamics trawl fishery in generating profit. Vertical integration Norwegian codfish industry spatial temporal flexibility to allocate effort make trawlers less vulnerable fluctuations. Minimizing risk leads ine...
