Abstract:
Rearing techniques for the larvae of the Black Sea turbot Psetta maxima
have been developed at the Central Fisheries Research Institute (CFRI) in
Trabzon since 1997. Research programs have been focused on finding out
optimum rearing conditions regarding to larvae and juvenile rearing
technology. Black Sea turbot were kept in indoor flow-through tanks and fed
live food, rotifers and Artemia, for 45 days from hatching. The
number of juveniles (100 mm TL) produced at CFRI increased from 8,000 in
1998 to 27,000 in 2000 but dropped to 14,000 in 2001. Production failed in
1999 because of trouble with the water intake system. For the future, CFRI
aims to (i) establish spawning techniques for hatchery-bred broodstock, (ii)
improve larval survival, and (iii) formulate a high-quality artificial feed.
A number of private companies in Turkey intend to invest in commercial
production of turbot by the techniques developed at CFRI.
