In aquaculture and fisheries, the value chain consists of all the various processes and activities involved in
bringing fish, shellfish, and aquatic plants to market. In some regions it can be an indicator of the
economic welfare of poor communities involved in small-scale operations. In order to maximize
smallholder participation...

Most fish stocks worldwide are not optimally exploited and are therefore are producing less in biologic and economic terms that what it could be obtained. MSY objective for all the stocks by 2015 is put forward by several countries as management target to be achieved, while other countries such as...
Human-induced changes in life-history traits have been observed for many harvested populations, with a component of those changes being attributed to an evolutionary (i.e., genetic) response. Most notably, fish stocks that experience high fishing mortality show a tendency to mature earlier and at a smaller size. Some have suggested that...
The Baltic Sea is referred as the most polluted sea in the world. The most serious problem is the eutrophication that is a consequence of nutrient loading through human based activities. Nutrient enrichment has led to growth of phytoplankton that has induced increased algal blooms and oxygen depletion in the...
The introduction of culture-based fisheries (CBF) in small scale irrigation systems is increasing the marginal value of water in rice farming. The amount of water that is used in Sri Lanka for rice farming could be utilised to generate more profitable non-crop economic activities such as CBF. This paper examines...
Motivated by the evidence that many collapsed stocks have failed to recover despite fishing mortality has been reduced, or even when a moratorium is currently in effect, we develop a spline methodological approach to analyze the stochastic population dynamics of fish stocks at low stock levels. The aim of this...
