When dealing with time, a fishery manager faces a major difficulty. On an N-period time horizon, should he follow
several short-run objectives for every n sub-period, or should he consider only the long-run objective? If a European
manager trying to implement a stock recovery plan prefers to achieve the long-run...
El-Nino Southern Oscillation has many impacts on marine environment. During El-Nino 1997-1998, there has been a change in sea surface temperature in Bali water. Bali water is an important contributor for pelagic fisheries, such as Sardinella lemuru, Thunnus sp, Katsuwonus pelamis, and Euthynnus sp. Sardinella lemuru is emphasized, because the...
A key conclusion of 'Net Benefits' - the landmark 2004 strategic review of the UK fishing industry - was that a sustainable UK fleet must make long-run profits adequate to invest in new boats, improve safety levels, pay good wages for skilled staff and be able to survive in years...
Traditionally, European fisherwomen were often involved in fisheries sector by selling fish. Today, their contribution is more diversified with very limited legal recognition: management of fishing enterprise, maintenance of gears. Fisherwomen continue to sell fish because it is often a good way to get a better price. Confronted with economic...
The introduction of modern trawl fishing in Norway after the Second World War was intended to be the very platform for the modernisation of the fishing industry. Right up to the end of the seventies, market orientation and the absence of state regulation of fishing were on the agenda. However,...
The paper examines fisheries co-management arrangements in enhancing organizational resilience and social equity at the municipal and city level in Western Visayas, Philippines in the 1992-1998 and the post-1998 periods. Field visits and interviews, conducted intermittently from April 2001 to March 2002, reveal that a perceived deterioration and degradation of...
Managed fisheries are frequently structured on a sector by sector basis with each sector defined by the type of user or use, for example commercial, recreational and indigenous sectors. Management arrangements for a sector, however, may not be formally integrated with those for other sectors. Consequent competition between sectors for...
Fishing communities have always had an obvious economic interest in fishery management as it affects their short-run and long-run prosperity. Many fishing communities are now interested in a more active role in the form of co-management, community-based management, or community property rights. The primary research focus in communities and fishery...
In this paper, a new test for causality in demand on markets supplied by both farmed and captured fish is
presented. This method is applied on markets for trout and potential substitutes imported to Germany, to
identify market delineation and causality in demand. It is found that markets for small...
This paper analyses the effect of adopting certain policies of internalising environmental costs on the optimal management of farms. In particular, the optimal harvesting time is analysed once these policies have been implemented. Fish growth and contamination diffusion are represented by means of dynamic stochastic models, including the uncertainty inherent...
