Video technology has been used as a tool in research for many years. However, its widespread use as a fisheries management tool has been limited due to its relatively high cost. This is changing as video technology becomes a household commodity now widely available throughout the world.
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.
Worldwide, there are many substantial coastal aquaculture and stock enhancement operations based on collection of wild juveniles. These include: growout of shrimp (Penaeidae), milkfish (Chanos chanos), eels (Anguilla spp.), yellowtail (Seriola quinqueradiata), southern bluefin tuna (Thunnus maccoyii), edible oysters (Ostreidae) and mussels (Mytilidae); stock enhancement of scallops (Pectinidae); and the culture of pearls in farmed blacklip pearl oysters (Pinctada margaritifera). The growout of wild puerulus larvae of spiny lobsters (Palinuridae) is also developing rapidly.
There are 58 species of Clarias recognized in FishBase (as of January 2009), 33 in Africa and 25 in Asia. Aquaculture of clariids is important with 30 countries reporting a total production of over 300 000 t worth nearly US$400 million in 2006. Most production involves the African Clarias gariepinus (Burchell, 1822) and three Asian species, Clarias batrachus (Linnaeus, 1758), Clarias macrocephalus (Günther, 1864) and Clarias fuscus (Lacep'de, 1803). In much of Asia, hybrids of introduced C.
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.
This report provides an assessment of the livelihoods strategies of the poor people dependent on inland fisheries in Bangladesh, Cambodia, the Lao PDR and Vietnam. Drawing upon the results of a one year investigation under the Project entitled "Understanding Livelihoods Dependent on Inland Fisheries", policies and institutions for fisheries management and livelihoods assets of the stakeholders in inland fisheries in the four countries. The report also discusses the trends and changes in fisheries and wetland resources.
This chapter discusses the collection of data on small-scale fisheries in developing countries, the limitations of national data systems and progress in synthesizing collected data.
Early computer applications in temperate stock assessment are briefly reviewed, along with some properties of present lines of programmable calculators and microcomputers. Differences and similarities between temperate and tropical fish stocks are also reviewed, emphasis being given to implications for stock assessment.
Muscular injection has become one of the direct methods for transferring foreign DNA into organisms. The technique has been recently introduced in the development of vaccines and gene therapy. Vaccine development, in particular, would be desirable in managing viral diseases in farmed fish. In this study, the technique was performed on seabass (Lates calcarifer) and was found that the foreign gene could be transferred successfully through injection into the muscles.
A discussion is presented on the role played by customary marine tenure (CMT) institutions in the regulation of fisheries in the Pacific Ocean Islands. Particular reference is made to the system in operation in Marovo Lagoon, in the Solomon Islands, whereby a number of defined clans control resource use within defined areas of land and sea. It is believed that such systems have considerable capacity for handling and adapting to new circumstances, thereby becoming potentially important tools in the contemporary management of fisheries and of the coastal zone in general.
