“…To increase ingestion of live food by larvae, it is necessary to supply it in greater quantity, however, this practice is not recommended for commercial cultivation due to the high cost of Artemia cysts, suggesting supplementation with inert moist diets, mainly beginning at stage IX for M. carcinus (Coelho-Filho et al, 2018). However, Santos et al (2007) found good results for larviculture of M. carcinus when the formulated diet was combined with Artemia nauplii beginning at stage VI.…”

Food acceptance in different larval stages of Macrobrachium carcinus was evaluated by investigating the stage at which the ingestion of inert moist diet food begins and by the incidence of Artemia nauplii and inert moist diet in the digestive tract throughout development. Two experiments were carried out: in the first study, the acceptance of the inert diet was evaluated in 60 larvae of each stage (I to XII) fed ad libitum after two hours of fasting. The inert diet was 100% accepted at zoea stage V. In the second study, newly hatched larva was then kept in larval tanks and fed with Artemia nauplii and inert moist diet simultaneously. Fifteen minutes after feeding, 50 specimens of each larval stage were examined and evaluated for the ingestion of these foods. Larvae at stage I did not feed, while larvae at stage II consumed both live and inert food. From the stage of zoea IX, the exclusive consumption of Artemia nauplii was not verified. These data indicate that feeding M. carcinus in larviculture can be initiated at stage II with inert moist diet and Artemia nauplii, and an exclusive supply of inert moist diet from stage IX can be recommended.

RESUMEN.Los langostinos del género Macrobrachium con interés económico y pesquero son bien conocidos y explotados en casi todas las comunidades ribereñas de Latinoamérica. Sin embargo no han sido estudiados apropiadamente, y su conservación está en riesgo. Las características económicas, sociales y culturales, de la mayoría de los países de la región, que se traducen en el deterioro del hábitat y la sobreexplotación pesquera, ponen en peligro de desaparición las poblaciones de este género de macroinvertebrados acuáticos. De esto, se desprende que todas estas especies están escasamente estudiadas y el estado actual de sus poblaciones no es conocido, si bien en el caso de M. amazonicum hay numerosos estudios. Las técnicas de cultivo es el rubro en que más investigación se ha realizado. En este trabajo se resume el conocimiento que se tiene sobre las especies nativas de Macrobrachium en Latinoamérica y se discute su importancia económica y necesidades de conservación.
