The Continued Development of a Larval Rearing Technique for Turbot

Summary

Eggs of turbot, Scophthalmus maximus, were transported from the White Fish Authority’s Marine Farming Unit, Hunterston and the Ministry of Agriculture, Fisheries & Food Unit, Lowestoft at the eyed ova stage and hatched in tanks at the Authority’s Marine Farming Unit, Ardtoe. The tanks, with constant illumination and temperature control, were stocked with rotifers, Brachionus plicatilis and algae (mainly Phaeodactylum sp) before the eggs were installed. The larvae were fed successively on rotifers, various stages of the brine shrimp, Artomia salina, and mysid shrimps, Leptomysis gracilis. A total of 1,764 metamorphosed fish were produced, the survival of the best batch of eggs being 1.1%.
