Turbot Hatchery Production 1981

Summary

During 1981 a total of 988,900 day one (dl) turbot larvae commenced rearing at the Hatchery at the Marine Farming Unit, Ardtoe. These comprised of 544,600 larvae from WFA spawning stocks at Ardtoe and Hunterston and 434,400 larvae originating at Scottish Sea Farms Hatchery at South Shian. In addition, a batch of 19,000 turbot/brill hybrid larvae was received from MAFF Lowestoft. Larval rearing methods closely followed those of 1980. The eggs produced at Ardtoe in 1981 (6.5% hatching rate) were of poorer quality than those of 1980 (16% hatching rate). This almost certainly reflected mortalities among proven female spawners between the two seasons.
