Previous work has shown that it is possible to grow the sea urchin, Psammechinus initial-is, alongside Atlantic salmon, Salmo salar, in a polyculture system. The intensive nature of salmon fam-ling demands the use of antibiotics, such as oxytetracycline (OTC), administered with the feed, which has the potential to accumulate within the edible part of the urchin, the gonad. There is little information on the effect and potential for accumulation of antibiotics in echinoderms. Thus, accumulation and residue elimination of OTC in the gonads of the echinoid, P. miliaris, following oral administration were evaluated in urchins of high and low nutritional status, under laboratory conditions. A commercially prepared, medicated salmon food (29 mg OTC g(-1)) was fed to urchins ad lib for 12 days.
