Fisheries management is an issue that draws out conflicting responses
about the role of the state, the market and civil society over the
management of natural resources. As an individual, anybody who is
exploiting the common resource will not think of any conservation because
the benefits in the short term...
Marine conservation measures such as moratoriums challenge the economics of fisheries. Efficiency of moratoriums depends on the acceptation by fisheries of such conservation measures. If the measure is unaccepted by fisheries the moratorium is not respected which leads the stock to extinction. The purpose of this article is to identify...
The need for management of the marine ecosystem using a broad perspective has been recommended under a variety of names. This paper uses the term Ecosystem Management, which is seen as a convergence between the ecological idea of an organisational hierarchy and the idea of strategic planning with a planning...
Ecosystems are one of the most productive fishing grounds in the world, with important commercial and valuable fish stocks. However, overfishing, IUU activities, discards, habitat destruction and alteration of the biogeochemical conditions of the ecosystem combined with an increase in fish demand continue to drive fisheries to an alarming situation....
