As an alternative to the culture of traditional fish,
experiments have been started with black-spot sea
bream (Pagellus bogaraveo) and are summarized
here.
Two groups of bream (B-1 and B-2) with 63 fish of
mean weight 173 g and 67fish of mean weight 217 g,
respectively, were captured on the NW coast of Spain
between September and December 1991,
transported to the laboratory, and maintained in
12 m tanks.
After about 30 days acclimation, lengths and weights
of all fish were measured. These measurements were repeated at 2 month intervals,for 14 months in the
first group and 10 months in the second. The mean
weights reached at the end of these periods were
462 g and 383 s. respectively.
Fish were fed with laboratory prepared moist food.
and the amount eaten daily was controlled. Survival
rate at the end of the experiment was 90.5% in group
B-1 and95.5% in group B-2. Temperature, measured
daily, ranged from 12ºC to 20°C.
This paper provides information on the capture,
transport, acclimation and maintenance of the fish
throughout the experiment.Versión del editor0,000
