This study was carried out to evaluate the dietary threonine requirement by measuring the plasma free threonine and ammonia concentrations in rainbow trout, Oncorhynchus mykiss after dorsal aorta cannulation. A total of 70 fish (average initial weight 506±8.2 g) were randomly distributed into each of the 14 net cages (5 fish/cage). After 48 hours (h) of feed deprivation, each group was intubate...

Stocking density is considered one of the important factors affecting fish growth. But, information related to impact of stocking density on growth performance of monosex tilapia population under the ecological conditions of Gangetic plains in West Bengal, India is limited. The aim of our study was to compare the growth potential of monosex tilapia at various stocking densities and to determine...

In the present study, a semi-analytical model based on small-amplitude wave theory is developed to describe fields around single gravity-type cylindrical open fish net cage. The cage may be submerged different depths below free-water surface. modelled as flexible porous membrane, and deflection of chamber expressed by transverse vibration equation strings. velocity potential expanded in form Fo...

Abstract Salmon farming in Chile constitutes one of the nation's principal food exporting sectors. In the seawater stage, one of the most important in the farm production chain, salmon are cultivated in floating cages fitted with nets that hold the fish during the entire grow-out process. The maintenance of the cage nets is carried out at land-based facilities. This article reports on the creat...

Fish aquaculture for commodity production, fisheries enhancement and conservation is expanding rapidly, with many cultured species undergoing inadvertent or controlled domestication. Cultured fish are frequently released, accidentally and deliberately, into natural environments where they may survive well and impact on wild fish populations through ecological, genetic, and technical interaction...

The Front Cover shows the synthesis of an amorphous cationic porous metal–organic material CL-aMOC-1 through covalent linking a large cage with aromatic diamine linker. Chinese dragon represents CL-aMOC-1, which can adsorb toxic oxo-anions (represented as fish) high capacities and rapid kinetics in water. More information be found Full Paper by S.-R. Zheng co-workers.

The Instituto de Investigaciones de la Amazonia Peruana (IIAP) is the leading governmental organization working in aquaculture and fisheries research in the Peruvian Amazon region. In addition, IIAP produces fingerlings, offers training courses, and works with nongovernmental organizations (NGOs) endeavoring to promote fish culture. This report summarizes fieldwork and survey results from rural...
