Simping clam are found spreadly in the nourthern coast of Java sea. Its taste is sweet and delicious. People in the coast served in boiled or fried with mixed vegetable for their dish. In fact, simping clam is considered as the pretigeous menu in international hotel and restaurant. At the...
The coastal zone is a dynamic area surrounding the interface between land and sea. The coastal area and its resources offer great benefits and opportunities for human use. Most coastal activities in Tanzania rely on the natural resources that the coast offers (fishing, forestry, agriculture, tourism, mining, salt production mariculture...
In the past three and a half a century since fisheries development was embarked upon in West Africa, the significant contributions of women in sustaining the socio-economic livelihoods of their families has been neglected and taken for granted. Development and support systems have paid much less attention to the economic...
In this paper an extended version of the well-known Faustmann model is developed for solving the rotation problem in fish farming. Two particularly important aspects of the problem are emphasized: namely first, the possibilities for cycles in relative price relationships and second, the problem with limitations in release time for...
The presents a theoretical analysis of the operation of a commercial fishery in the presence of marine reserves. The sustainable yield and revenue curves for reserves are derived and compared to the analogous curves with no reserves. It is shown that reserves will always reduce the sustainable harvest for any...
While most bioeconomic models assume that vessel operators use profit maximizing behavior, it is sometimes argued that participants use other operational goals. The purpose of this paper is to compare how vessel behavior, the bioeconomic equilibrium and the path to achieve it are changed if participants use profit goal behavior....
The current Senate Bill to reauthorize the Magnuson/Stevens Act, the key US fishery management law,
will allow some significant changes in the way that Individual Transferable Quota programs can be
developed. First, the bill will expand the range of individuals who will be permitted to obtain harvesting
privileges. In addition...
Auparavant le secteur des pêches ne s’intéressait guère qu’aux ressources et aux captures. Nos spécialités étaient des biologistes, des techniciens des pêches ; nos administrations de tutelle étaient celles des marins pêcheurs, nos recherches étaient essentiellement orientées vers la biologie des espèces, l’environnement de leur habitat, les modèles de gestion...
This paper examines the constitution of 'sustainable management' within the context of the New Zealand marine environment. Firstly this paper examines the difference between 'sustainable ecosystems' and 'sustainable utilisation'. The distinction is important if we are to make sense of the different ways in which various stakeholders (fishers, fisheries companies,...
Generalised linear estimation and multi-layer perception neural network modelling techniques were applied to the Scottish trawler fleet data in order to estimate which inputs have the greatest impact on boat profits and output. Both produced comparable estimates that revealed inelastic and non-linear response to vessel power and length, negative response...
