Carotenoids in ornamental fish farming

      The aquaculture industry has grown dramatically in recent years, with a multimillion-dollar market. There are a variety of freshwater fish, marine fish, mollusks, and ornamental fish cultivated in this industry. The pigment and coloring of ornamental fish are important characteristics for marketing. In edible fish, carotenoids are responsible for the pigmentation of body tissue, while in ...

Operational Support in Fish Farming through Case-Based Reasoning

Farmed fish is the third biggest export in Norway (around NOK 30 billion/e3.82 billion/US$ 5.44 billion in 2010), and large fish farms have biomass worth around NOK 150 million/e19.38 million/US$ 26.72 million. Several processes are automated (e.g. the feeding system), and sensory logging systems are becoming ubiquitous. Still, the key to successful management of a site is the operational knowl...

Farming up Mediterranean food webs.

One of the effects of fisheries on ecosystems is that they tend to remove the larger, higher-trophic-level species and thus progressively lower the mean trophic level (TL) of the landings. This effect is known as “fishing down the food web” (Pauly et al. 1998; but see also Essington et al. [2006] for addition of low-TL fisheries instead of decline in high-TL fisheries, termed “fishing through m...
