A couple weeks ago, Daniel Pauly and I got the paper Funding Priorities: Big Barriers to Small-scale Fisheries published in the journal Conservation Biology. In our analysis, we try to demonstrate that conservationists attempts to encourage sustainable fisheries at the market level should place at least equal emphasis on eliminating harmful fisheries subsidies as on consumer-based approaches (e...
Global fisheries statistics exist since 1950, as part of the United Nations’ effort to generate statistics suitable for monitoring the development of the world economy (Ward, 2004). With some limitation to be discussed later, the statistics assembled and maintained by the Food and Agriculture Organization of the United Nations (FAO) allow tracking the growth and expansion of fisheries by countr...
Globally, small-scale fisheries are influenced by dynamic climate, governance, and market drivers, which present social and ecological challenges and opportunities. It is difficult to manage fisheries adaptively for fluctuating drivers, except to allow participants to shift effort among multiple fisheries. Adapting to changing conditions allows small-scale fishery participants to survive econom...
The National Marine Fisheries Service (NMFS) is charged with restoring and protecting anadromous Pacific salmon stocks in all habitats of U.S. waters, including their period of residence in estuarine and oceanic waters. Recent studies have implicated the estuarine and coastal phase of the salmon life cycle as being of equal importance to the freshwater phase in determining production. Evaluatio...

The Great Lakes Fishery Commission, recognizing the importance of social impacts on Great Lakes fisheries and the shortage of information on ‘‘human dimensions,’’ launched a new research theme. It seeks to fill knowledge gaps in the areas of legal and institutional frameworks governing fisheries, constructing effective processes that better inform management decision making, and the role and im...

The aim of the Sea Around Us Project is to quantify, in ecological and economic terms, the impact of fisheries on the marine ecosystems of the North Atlantic, and to evaluate the costs and benefits of various scenarios of mitigation, such as status quo, rebuilding of depleted resources and implementation of closed areas. Dealing with these issues requires a methodological package related to, bu...
the bottom trawl selectivity parameters (22mm cod-end mesh size) were determined for saurida undosquamis , mullus barbatus , upeneus pori , and pagellus erythrinus along karatas coasts of turkey in northeastern mediterranean waters during fishing season for the year 2002-2003. the lengths at first capture (l 50 ) values for s. undosquamis , m. barbatus , u. pori and p. erythrinus were 12.57, 9....
