This study examined the sea cucumber industry in the Philippines through the value chain lens. The intent was to identify effective pathways for the successful introduction of sandfish culture as livelihood support for coastal communities. Value chain analysis is a high-resolution analytical tool that enables industry examination at a detailed level. Previous industry assessments have provided a general picture of the sea cucumber industry in the country.
The effects of two common weedy grasses in sub-saharan Africa were evaluated as fertilisers in small-scale Nile tilapia ponds for 21 weeks.
Investigations in laboratory, tank and pond systems were carried out at teh Domasi Experimental Fish Farm, Zomba, Malawi to evaluate the liming properties of firewood (sterculia quinquiloba Garcke, Schumach) ash. This article suggested that firewood ash has potential both as a low-cost liming agent and as a phosphorous fertilizer for smallholder fish ponds in developing countries.
Fisheries in the USA are managed under the Magnuson Fishery Conservation and Management Act of 1976 (MFCMA). By 1991, it was reported that fish stocks had declined considerably since the act came into force. A national Committee in Fisheries was set up in 1992 to investigate ways of improving fisheries management regimes. The committee's seven recommendations framed in four broad areas are: (1) prevent overfishing; (2) improve the institutional structure; (3) improve the quality of fishery science and data; and (4) move toward an ecosystem approach to fishery management.
L’essor de la pêche commerciale, notamment de l’exportation de la perche du Nil, a entraîné la réduction des stocks de poissons et de la disponibilité du poisson auprès des populations de la région du Lac Victoria. Cette baisse ne menace pas seulement les moyens d’existence des pêcheurs artisanaux et des transformateurs mais elle met également en danger la sécurité nutritionnelle et alimentaire des populations de la région.
Information on fisheries resources in Bangladesh and S.E. Asia is fragmented and has not taken account of poor people and their livelihoods. Research has been supply-led, resulting in limited uptake and gains for the non-poor. Often decisions are based on national level priorities, overlooking the needs of local people, especially the poor, and thus posing a severe threat to local livelihood assets including fisheries.
Aquaculture is a rapidly expanding sector of the global economy. Development of the industry under various national and regional jurisdictions has resulted in a diversity of regulatory frameworks. This manual has been produced in response to requests for guidance on the application of risk analysis with respect to aquaculture production.
This study aims to update the typology of shrimp farms in a province of the Mekong Delta’s coastal area. We analyzed technical and economic characteristics of 170 farms using factor and cluster analysis on the different variables collected during the survey. This allowed us to characterize four different shrimp production systems: intensive commercial and intensive family farms, and the more extensive brackish water polyculture and rice–shrimp farms. The systems differed in their level of intensification, diversification and origin of labor.
The article features two most commonly techniques for gene transfer in fish, microinjection and electroporation.
Fisheries management is still an infant discipline fighting to gain status and recognition among fishery scientists. For some, fisheries management is the "art" of inducing fishermen to fish as much as possible with the best available technology. For others it is determining optimum sustainable yield levels of fish populations and of identifying measures to restrict effort or access so that conservation principles are not violated. For others, it is the way fishing activity should be conducted in order to obtain the highest possible catch and net benefits to society over time.
