Developing countries dominate the shrimp scene.

Of the 101 shrimp-producing countries listed in the 1983 FAO Yearbook of Fishery Statistics, 70% are developing countries; the 4 leading producers from the Asia/Pacific region were India, China, Thailand, and Indonesia. Thedemand for shrimps in the world market and the shrimp supply situation are examined, considering also the need for aquaculture. Shrimp culture in India, Indonesia, Philippines, Ecuador, Brazil and Mexico is described briefly.

An intra-farm study of production factors and productivity for shrimp farms in Bangladesh: an index approach

The production characteristics of shrimp farming in Bangladesh are reported based on a panel of farms for the period 1998 to 2002. The data allow for a profit decomposition based on the Törnqvist index, where differences in relative profits can be explained by differences in productivity, prices, and pond size. The indices indicate that pond size is the most important factor in determining profitability and that the largest farms are the most profitable. However, productivity measured as profit per hectare is only weakly positively correlated with pond size.

Sandfish (Holothuris scabra) with shrimp (Penaeus monodon) co-culture tank trials

Seven tank trials were undertaken involving the co-culture of sandfish and shrimp on sand. Sizes, stocking densities, feeding and other conditions were all varied. Results indicated that powdered sargassum did not support sandfish growth, although it may have prevented starvation, which otherwise killed juveniles within three to six weeks.

Incidence of human pathogenic bacteria in shrimp feeds - a study from India

The incidence of various human pathogenic bacteria in commercially available and home-made shrimp feeds used on some farms in India was analyzed. The Total Heterotrophic Bacteria in the commercial feed samples ranged between 103–105 cfu g-1 and those in the farm-made feeds between 106-107 cfu g-1. No bacteria of significance to human health were found to be associated with any of the commercial feed samples analyzed, while farm-made feeds analyzed during the study showed a high incidence of various human pathogens such as Vibrio parahaemolyticus, V.

Environment and aquaculture in developing countries.

Contains 15 reviews on the environmental impact of aquaculture including inland and coastal ecosystems, integration of agriculture and aquaculture, shrimp culture, antibiotics and other trace environmental contaminants, toxic algal blooms, socioeconomic aspects and regional overviews for Africa, Asia and Latin America. These are also transcripts of discussions on these topics, with recommendations and a framework for decisionmaking when considering the environmental impact of aquaculture development.

Developing a consultative Bayesian model for integrated management of aquatic resources: an inland coastal zone case study.

This article presents the methodological aspects of the development of a decision support system (DSS) based on Bayesian networks and aiming at assisting in the management of water-dependent resources (rice, fish, shrimp and crab). The principles of Bayesian networks are introduced, then the steps of model development are detailed and illustrated by the BayFish model being developed in the inland coastal zone of Bac Lieu Province (Vietnam). The particular feature of this DSS is that it is based on the contribution of local stakeholders.

Typology of shrimp farming in Bac Lieu Province, Mekong Delta, using multivariate statistics

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.

On holism, reductionism and working from 9 to 5

A discussion is presented on the 2 approaches - holism and reductionism - in the study of environmental sciences, making reference to various projects presently being conducted by ICLARM and its collaborators using the holistic approach. Schematic representations are given of ICLARM's FISHBASE, the ECOPATH II model of the Peruvian upwelling ecosystem and submodels which may be incorporated in large simulation models of the upwelling system, and also material flows in a rice-fish/shrimp integrated farming systems of the Mekong Delta, Vietnam.
