“…In the present study, exocrine pancreas of stinging catfish larvae fed exclusively with DR-A (Artemia nauplii) and co-fed with Artemia, zooplankton and microdiet (DR-D) had larger pancreocytes arranged in acini and a high amount of zymogen granules, whereas that of larvae fed with other dietary regimes had comparatively smaller pancreocytes and a lesser quantity of zymogen granules. Further, other studies have suggested that in addition to providing some essential micronutrients, Artemia might be contributing to the activation of zymogens or digestive hormones (Petkam and Moodie, 2001) or might be triggering the secretion of endogenous enzymes in comparison to artificial diets and zooplanktons (Pedersen and Hjelmeland, 1988). In addition, it has also been observed that larvae fed with Artemia had higher tryptic activities compared with the weaned larvae in pikeperch Sander lucioperca (Hamza et al, 2007).…”

“…Unlike channel catfish, Ictalurus punctatus (Rafinesque, 1818), whose first feeding fry are usually fed on dry formulated food, R. quelen and other catfish species, have not been successfully fed only on dry diets yet (Kerdchuen & Legendre ; Petkam & Moodie ; Hung et al . ; Zheng et al .…”

Growth, survival and fatty acid composition ofRhamdia quelen (Quoy and Gaimard, 1824) larvae fed on artificial diet alone or in combination with Artemia nauplii Abstract Black catfish (Rhamdia quelen) is a species of interest for aquaculture in Brazil, Argentina and Uruguay. A feeding trial was conducted to evaluate the effect of feeding R. quelen larvae on either only an artificial diet or in combination with Artemia nauplii (AN) on larval performance and fatty acid composition. For 12 days, larvae were fed from first feeding (3 days after hatching, TL = 5.88 ± 0.23 mm) with artificial food only or a combination of artificial food and AN (co-feeding). At the end of the trial, total length of co-fed larvae was significantly higher than that of larvae fed solely artificial food (P < 0.001). No significant differences were found in survival rates. Co-feeding microdiet with a small amount of AN significantly affected larval fatty acid composition. Lipid and fatty acid composition of food and larvae revealed the importance of n-3 fatty acids for growth of black catfish larvae and that, as most freshwater fish, R. quelen larvae can elongate and desaturate linolenic acid to n-3 highly unsaturated fatty acids. Results suggest that R. quelen larvae can be fed from first feeding on microdiets as unique food source, although better larval performances are obtained by co-feeding with a small amount of AN.

“…Several studies carried out on this species have pointed out jundiá as a promising new species for aquaculture in Brazil (Piaia et al, 1999;Gomes et al, 2000;Uliana et al, 2001;Carneiro et al, 2002). One good reason is that jundiá larvae seem to accept inert dry diet from the very beginning of exogenous feeding.…”

“…A number of other important aspects related to nutrition, species, fish biology, and husbandry conditions, which determine the success of using combined feeding, are not yet fully understood. For instance, there appear to be specific periods during development when fish larvae will feed on, and metabolize formulated diets, and that can be accounted for a behavioral and a physiological capacity (Cahu & Zambonino-Infante, 2001;Petkam & Moodie, 2001). Moreover, some fish species larvae apparently are better adapted to the utilization of nutrients from formulated diets than others.…”

Live diet (LD) dependence and the lack of suitable formulated diets (FD) are major constraints for the expansion of larviculture of many fish species. The low digestibility and nutritional quality of FD are factors that might explain their failure as a stand-alone starter food. To determine whether FD in combination with LD (zooplankton) may efficiently increase larval growth and survival of jundiá (Rhamdia quelen), when compared to fish fed by either types of diet alone, jundiá larvae (5.57 mm; 1.41 mg) were initially stocked into 12 10-L aquaria (100 larvae per aquarium). Replicate groups (n=4) were fed ad libitum one of the three diets for 20 (when fed FD) or 48 days (when fed LD or the combined diets). Larvae fed FD alone presented significantly lower survival and growth rates as compared to larvae fed LD or a combination of both (co-fed). In addition, co-fed larvae grew better (170 mg) in relation to those fed solely with LD (110 mg). Such better performance of combined feeding indicates that most of the required nutrients are in balance when both diet sources are included. More can be learned about fish larvae nutrition by further testing the effect of feeding combined diets, which include zooplankton, than only testing new ingredients or protein sources commonly used in the elaboration of juvenile or adult fish feeds.

A baixa digestibilidade e a qualidade nutricional das DFs são alguns dos fatores que explicam o insucesso quando as larvas recebem apenas FD. Para avaliar o efeito da combinação da DF com o AL no crescimento e na sobrevivência de larvas de jundiá (Rhamdia quelen), comparando com o uso separado da DF ou do AL, larvas recém eclodidas (5,57 mm; 1,41 mg) foram estocadas inicialmente em 12 aquários de 10 L (100 larvas por aquário). Quatro réplicas foram alimentadas ad libitum com uma das três dietas por 20 (para DF) ou 48 dias (para AL ou a combinação DF + AL). As larvas alimentadas com apenas DF apresentaram crescimento e sobrevivência reduzidos quando comparadas àquelas alimentadas com AL ou a combinação DF + AL. Adicionalmente, as larvas do tratamento DF + AL apresentaram maior crescimento em peso (170 mg) que aquelas alimentadas apenas com AL (110 mg). O melhor desempenho das larvas alimentadas com DF + AL mostra que a maioria dos nutrientes exigidos pelas larvas é fornecida mais adequadamente quando ambas as dietas são fornecidas juntamente. Contudo, trabalhos sobre nutrição larval poderão contribuir ainda mais sobre a elucidação deste tema quando feitas comparações com o uso combinado de DF + AL, do que apenas testando isoladamente novos ingredientes e fontes protéicas normalmente utilizadas na elaboração de dietas para juvenis ...
