The aim of this study was to investigate the interaction between fish cage culture and sediment bacterial contamination in the area southern of Caspian Sea. For this purpose, sampling of sediment was collected in Mazandaran province (Nowshahr region) during the rainbow trout farming period at different distances (shadow, 200 and 1000 m from the cage) in 2017-2018. The results showed that in the...

The potential of irrigation reservoirs in northern Ghana to support Nile Tilapia (Oreochromis niloticus) production 1 m3 budget cages was assessed over six-months three (Bontanga, Golinga and Libga). Fingerlings with a mean weight 17.0 ± 5.0 g were randomly stocked at 50, 100, 150, 200 250 fish per cage duplicate fed commercial tilapia feed (Raanan, 30% protein level) 3 5% body weight. r...

The proximate composition, amino acids and fatty acids composition in the muscle of wild, inshore and offshore cage-cultured large yellow croaker, Pseudosciaena crocea (Richardson, 1846), were determined to identify nutritional differences. Wild fish groups showed highest content of moisture and crude protein, but the lowest lipid content. Offshore cage-cultured fish showed significantly higher...

The experimental cage culture was conducted at Shirati bay, Lake Victoria from February to August 2013, to investigate the impacts of the small scale cage culture on the environment. Three locations along the cages, at the intermediate and one in the offshore (control) were sampled for water quality parameters, phytoplankton and macro invertebrates. A notable increase in nutrient concentration ...

Aquaculture is increasingly important world-wide as landings from natural captured fisheries is unable to meet the demand for fish. The Batang Ai Hydroelectric Dam Reservoir, located in Sarawak, Malaysia, has been an aquaculture site for the last 18 years. However, little information is available on the impact of aquaculture on the water quality of the Batang Ai reservoir. Therefore, the object...

The demand for and costs of producing land-based animal protein continues to escalate as the world population increases. Fish is an excellent protein, but the catch-fishery is stagnant or in decline. Intensive cage culture of fish is a viable option especially in countries with lakes/rivers and/or a long coastline; however, disease outbreaks will likely occur more frequently with cage culture. ...

Abstract Fish cage culture has rapidly grown throughout Lake Victoria's shores, with Nile tilapia ( Oreochromis niloticus ) being the primarily cultured species. However, there is inadequate information on its economic viability. The study investigated feasibility of fish farming system in Victoria, Kenya, by evaluating relationship between cost inputs and revenue from sales analysing overall p...
