| The red porgy (Pagrus pagrus)is an important commercial and recreational species with very good prospect for aquaculture. Because significant mortalities, the mass production of this species is limited. This paper describes three weaning strategies to investigate their effects on the survival and growth of red porgy larvae reared in laboratory: A)traditional three-step weaning (rotifers - Artemia - diet)(control); B)one-step early weaning by co-feeding (rotifers - Artemia + diet), and C)one-step direct early weaning (rotifers - diet). Sigificative differences were recorded among treatments (P0.05). Best survival rate (45.6 ± 7.6 percent)and growth (7.4 ± 0.5 mm)were found in treatment B. Results indicate that co-feeding red porgy larvae with inert and live... |

| The first results in the development of a standardized methodology to estimate Mnemiopsis leidyi intake rates and their impact on fish recruitment are presented. M. leidyi capability to consume lyophilized fish eggs and level of consumption of such type of preys, Artemia nauplii and rotifera were assessed. Although M. leidyi can consume lyophilized fish eggs, intake rates were extremely low, often null and in all cases lower than those estimated for the other types of preys offered. The increase of feeding rate on each prey was proportional to ctenophores size growth. The results observed suggest that consumption of fish eggs would not affect recruitment. However, there is not a uniform methodology in the literature that allows for standardized... |
