First report of a swordfish (Xiphias gladius Linnaeus, 1758) beneath open-sea farming cages in the Western Mediterranean Sea
An adult swordfish (Xiphias gladius L.) was reported for the first time at coastal Mediterranean fish-farm facilities. This record highlights the necessity to assess the potential ecological changes to wild fish assemblages caused by coastal farming activity, especially to this type of endangered large migratory fish predator, which could be taken into account in future management strategies.
متن کاملNutrient compositional differentiation in the muscle of wild, inshore and offshore cage-cultured large yellow croaker (Pseudosciaena crocea)
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...

متن کاملEffect of production quotas on economic and environmental values of growth rate and feed efficiency in sea cage fish farming
In sea cage fish farming, production quotas aim to constrain the impact of fish farming on the surrounding ecosystem. It is unknown how these quotas affect economic profitability and environmental impact of genetic improvement. We combined bioeconomic modelling with life cycle assessment (LCA) to calculate the economic (EV) and environmental (ENV) values of thermal growth coefficient (TGC) and ...
متن کاملThe impact assessment of cage aquaculture on benthic communities along the south eastern Black Sea
The present study was conducted to examine the impact of cage aquaculture on benthic communities in coastal areas (depth 25 to 50 m) from fish farming operations located along the southeastern Black Sea (Ordu-Perşembe, Trabzon-Yomra and Rize central). Sampling was conducted seasonally from April 2007 to 2009. Sediment samples were taken using Ekman Grab (box core- 0.04 m2). Temperature, salinit...
