Abstract

The growth rate of the blue tilapia, Oreochromis aureus, was measured in fresh water, 15 ‰ salinity, and 30 ‰ salinity. The fish were given a hormone-treated feed to sex-reverse the females. Acclimations were achieved by raising the salinity only 5 ‰ per day. A biofilter and frequent water changes were used to maintain water quality in each 40 1 system. Synthetic sea salts were used to achieve desired salinity. The fish were grown for 87 days at 27°-30° C.

So significant difference in growth rate occurred among the three treatments. Salinity did not influence mortalities. All fish appeared to be males.
