Improvement in survival and growth rates during the initial life stage was achieved with rotifers. Apocyclops panamensis resulted in increased growth rates after rotifers. Pikeperch fatty acids served as a quality indicator. Live feed must provide linoleic acid during the first 7 days and docosahexaenoic acid from day 11 post hatch. This thesis established a balanced lipid phenotype for pikeperch larvae and juveniles in RAS.
