This paper attempts to review the use of antibiotics in aquaculture in Malaysia because of the heightened concerns over its use and abuse and its impact on human health and the environment. Health and environmental issues relating to antibiotic use and measures that can reduce or control the impacts are also discussed.
Urban agriculture is prevalent in Cameroon, the first country examined in this book of case studies, yet its role in urban life was little studied until the 1990s. At that time researchers began to look at some aspects of this complex phenomenon, such as the role of traditional leafy vegetables in the diet and incomes of the urban poor.
This is one of the four countries reports which provides an assessment of the livelihoods strategies of the poor people dependent on inland fisheries in Vietnam. The project aimed to characterise the poor, identify their dependence upon aquatic resources, the nature and status of those resources, and their vulnerabilities in relation to loss or mismanagement. Constraints and possible research priorities have been identified through consultations with poor fishers and other aquatic resource users, and with other organizations. Fisheries resource status has been summarized.
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.
This paper describes fishing activities of households in four communities located in a floodplain lake system of the lower Amazon river. An average of 42 households were interviewed about their fishing activity on a monthly basis. The fishery is a typical multi-gear, multi-specific artisanal fishery. Approximately ten types of fishing gear are utilized, of which the three main types of gillnets account for 51% of the total catch. The catch per trip averaged 15 kg, for an annual total of 2,295 kg per household.
Two opposing views exist in the literature on the potential role that international fish trade plays in economic development. While some claim that fish trade has a pro-poor effect, others denounce the negative effect of fish export on local populations’ food security and doubt its contributions to the macro-economy. In this paper, we explore this debate in sub-Saharan Africa. Our analysis did not find any evidence of direct negative impact of fish trade on food security; neither did it find evidence that international fish trade generates positive, pro-poor outcomes.
Tilapia farming in Kuwait is in its early stages. Slow growth, high production cost and poor demand are the major constraints to the expansion of tilapia culture in Kuwait. This article presents some suggestions for overcoming these problems to improve the economic feasibility of tilapia culture in Kuwait.
