Abstract:
Sea bass seed production of Turkey has increased rapidly in the last 5 to 6
years, which is comparable to those of some Mediterranean countries and has
reached the level of approximately 50 million fry in 2001. However, seed
production of this species is not expected to increase in the near future
because of the market saturation and the fall in the price of the final
product.
Recently, the survival, growth rates and the quality of sea bass fry have
improved considerably as a result of technical advances in larval rearing.
Nevertheless, more efforts are necessary to reduce production cost of
juvenile. With the current crisis on Artemia, the importance of
compound diets as alternative larval food is recognized.
This paper provides some important aspects of the culture techniques for sea
bass juvenile production, the characteristics of the rearing systems and
culture techniques adapted in commercial hatcheries. Moreover, some research
activities are geared to make the culture techniques economically viable.
The results of the studies on “off-season spawning” using photoperiod
and on weaning the larvae from Artemia to compound diets are also
presented.
