Creator:: Nuppenau, Ernst-August
Abstract:: There is much talk on recycling organic effluents, closing nutrient cycles, maximising energetic efficiency, and maintaining equilibriums between humans and nature, etc., even for lakes and estuaries. Aquatic systems provide us (humans) the service of recycling decomposable organics and deliver fish at the same time, notably, as long as the...

Creator:: Mohammad-Rezaei, Rassul
Abstract:: In natural resource economics, we sometimes observe a situation in which producers and consumers have direct access to the factors of production or can use some consumable products with little or no transformation. These goods are commonly referred to as “gifts of nature”. A factor of production is considered a...

Creator:: Nashandi, Wilbard
Abstract:: The open access nature of fisheries resources had caused application of excessive fishing effort to most World fisheries. Proper management of fisheries resources is vital for sustainability and its safe future utilisation. Most attempts to salvage fisheries resources had so far succeeded but have also created one or more problems....

Creator:: Matsuda, Yoshiaki
Abstract:: Human beings are now recognizing that fish are no longer free gifts from the nature and we have to manage it wisely. The current management schemes are more or less based on the allocation of fish by individuals or communities through rules and regulations, resulting in illegal fishing, high MCS...

Creator:: Guillotreau, P., Le Grel, Laurent, and Gonzales, Frederic
Abstract:: Fish are marketed with various intermediaries between producers and final consumers. The number and the nature of the intermediaries, market structures at each stage of the value chain and other factors related to the organisation of markets may substantially affect the transmission of information throughout the chain. The present study...

Abstract:: Atlantic salmon aquaculture is a growing industry in the Bay of Fundy on Canada’s Atlantic coast. The vast majority of aquaculture sites are concentrated in a relatively small coastal region of the province of New Brunswick (NB) where the industry is viewed as a major component of regional economic development....

Creator:: Martinez-Cordero, F. J., Seijo, J. C., and Juarez, L. M.
Abstract:: Sustainable aquaculture can be achieved when risk and uncertainly are incorporated in the analysis of the activity. This paper presents a precautionary approach to the feasibility analysis of a project for a commercial hatchery, applying decision theory. Two production scenarios were assessed, continuous and periodic, the later a combination of...

Creator:: Gonzales, Frederic, Guillotreau, Patrice, Le Grel, Laurent, and Simioni, Michel
Abstract:: A recent study in agricultural products has brought out evidence of asymmetrical transmission of price changes according to the sign (positive or negative) of past variation. Interestingly, asymmetry was more commonplace for products with a lower elasticity of supply due to the perishable nature of products. A similar study based...

Abstract:: En quelques années, l'Indonésie est devenue un des premiers pays producteurs de crevettes. L'extension et l'intensification rapide des élevages a des répercussions socio-économiques et écologiques majeures. Après un pic de 130.000 tonnes en 1992, la production est tombée à 100 000 tonnes en 1993. Depuis, le développement de nouveaux sites...
