“…Graeve et al 1994, Scott et al 1999. Therefore, FAs have also been proposed as markers of aquaculture influence due to the change of the FA composition of associated fauna like sea-urchins (Cook et al 2000, Barberá et al 2011, mussels (Gao et al 2006), shrimps (Olsen et al 2009), fish (Skog et al 2003, Fernandez-Jover et al 2007) and also in sediment (Samuelsen et al 1988, Henderson et al 1997. Olsen et al (2009) considered that only linoleic and α-linolenic acids can be used as clear aquafeed markers in shrimp Pandalus borealis.…”

Fatty acids (FA) have been applied as indicators of the influence of coastal sea-cage fish farming on wild fish communities in several recent scientific publications. Due to the relatively high conservation of FA composition throughout the food web, they are useful for characterizing trophic relationships. The increasing utilization of vegetable or alternative animal oils in the production of aquafeeds results in cultivated fish exhibiting higher levels of terrestrial FAs in their tissues. As previously reported, wild fish ubiquitously aggregate around fish farms as a consequence of the introduction of new habitat and the easy availability of food—fish farms act as enhanced fish aggregation devices (FADs). The influence of food pellets on the composition of wild fish has been detected in recent studies on salmon, sea bass and sea bream aquaculture, with increased levels of linoleic acid (18:2n-6) and a low n-3/n-6 ratio as clear indicators of the consumption of food pellets from the farms. The potential ecological and physiological effects on wild fish are presently unknown. In the present article, guidelines are proposed for the investigation and use of terrestrial FAs to track the effects of coastal aquaculture on wild fish communities and local fisheries, as well as the benefits or limitations of this technique

“…However, these studies did not specifically quantify fish feces contributions to bivalve diets. Gao et al (2006) estimated that dietary organic matter available to mussels held inside fish cages, during a period of low phytoplankton availability, consisted of 27.5% fish feed and 4.2% fish feces. The remaining fraction was naturally occurring organic matter.…”

“…The nutrient content in the organic matter is thus ingested and accumulated in the tissues of the organism instead of being dissolved in the water column or deposited on the seabed. Hence, the water quality can be improved (Haamer 1996, Gao et al 2006.…”
