Sea-cage Fish Farming and Declines of Wild Fish
نویسنده
چکیده
It has often been observed that after sea-cage fish farming begins in a coastal area, nearby wild fish populations steadily or precipitously decline due to elevated levels of pathogens and parasites. Such declines can be understood using three methods, in increasing level of mathematical difficulty: (1) an intuitive approach based on the inverse-square law of radiation applied to parasite transmission, (2) a probabilistic model that begins with the understanding that parasites regulate their hosts at least to some extent, and (3) an extension of the classical Anderson-May coupled differential equation model for macro parasites.

Nutrient 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...

The 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...
متن کاملRisk assessment for metazoan parasites of yellowtail kingfish Seriola lalandi (Perciformes: Carangidae) in South Australian sea-cage aquaculture
Metazoan parasites can threaten the sustainability and profitability of finfish sea-cage aquaculture. It is critical, therefore, to identify local parasite species and determine which are potentially harmful. Although several studies have documented parasite species on wild and farmed fish from aquaculture sites, few have used qualitative risk analyses to determine the likelihood and consequenc...
