Abstract :
This study assessed the growth and
survival over a year of two groups of 4-month-old turbot Scophthalmus
maximus (L.) derived from artificial fertilization with fresh (FG) and
cryopreserved sperm (CG). Growth in both groups, measured monthly in terms
of length and weight, were compared. Survival was also recorded. No
significant differences were found when we compared weight and length data
in both groups. Growth rates were similar between FG and CG young turbot
during 1
year.
Likewise, the same survival rate (92.2%) was found in both groups. Our
results show the good survival and growth of young turbot obtained from
cryopreserved sperm, and confirm the cryopreservation technique as a useful
tool for raising turbot for commercial purposes.
