Reproduction and larval rearing of the common sea bream (Pagrus pagrus), an experimental culture

Stephanou D., Georgiou G., Shoukri E.

Pagrus pagrus (average weight 30 g) collected from the wild matured and spawned, after rearing in tanks for slighty more than two years. The adapted to tank conditions and artificial diets very fast. They grew to an average weight of 300 g in one year and to 610 g at the end of the second year from collection. Spawning was spontaneous and lasted from the end of February until the end of April, 1995. The water temperature was 17-18 degrees C. Egg diameter ranged from 920-1050 mu and larval length from 2.50-3.20 mm. Larval feeding, using rotifers, begun on day 4, after the absorption of the yolk sack and the opening of the mouth and continued until day 26. The green water method gave the best results for larval rearing. AF grade artemia nauplii were given as from day 22 until day 27. On day 28 the larvae were fed with EG grade artemia nauplii enriched with HUFA. Dry food was given from day 33. Weaning was completed on day 45. The larval growth of P. pagrus is fast, however the larvae are very sensitive to stress, irrational nutrition and to handling. At the age of 3 months from hatching the average weight was 2.3 g and the average length 4.8 cm. It is considered to be a promising species for aquaculture diversification.
