Abstract:: It is well known that world production of shrimp, particularly farm-raised product, has increased significantly since the early-to-mid 1980's and that much of the product is directed to the U.S. market. Less well known is the fact that the product composition of the U.S. imported product (e.g., headless shell-on, peeled)...

Abstract:: The Southeast U.S. shrimp harvesting sector is one component of the shrimp industry that has generally been unable to make the adjustments needed in response to the growing import base and the resulting supression in prices. Not unexpectedly, therefore, requests for relief from the perceived problems associated with increasing imports...

Abstract:: 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,...

Abstract:: Research on omega-3 fatty acids of marine origin consistently indicates the value of these substances to human health, while seafood processors face the challenge of creating value-added products rich in omega-3 compounds that consumers identify as being both healthful and tasty. In particular, albacore tuna is considered to have large...

Abstract:: This research analyzes the effects that a redistributive fishing quota policy, within a collective rights quota assignment system, might have on the profits and employment of artisanal fisher organizations. The Chilean authorities have been pursuing a deliberate quota redistributive policy between ship-owners of different vessel categories. This policy has affected...

Abstract:: The main instrument used in fishery management is the total allowable catch (TAC). Fishery management often fails because TACs are set too high and do not sufficiently restrict fisheries. The question we address in this paper is why do decision makers choose inefficiently high TACs? Our approach is to model...

Abstract:: Investors in aquaculture are biased against the mangrove areas and prefer to site their farms in the upland parts of Southwest, Nigeria. This study was carried out to compare the yield performance in the two fish farm locations. The tools utilized included descriptive statistics, budgetary and cash flow analyses and...

Abstract:: 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...

Abstract:: 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...

Abstract:: En dépit de sa production halieutique qui occupe la première place dans le monde arabe et africain, le Maroc connaît une consommation de poisson de 7.5 Kg/personne/an, largement inférieure à la moyenne mondiale qui est voisine de 13 Kg/personne/an. Cette consommation est inégalement répartie. Généralement moyenne à forte, en bordure...
