Estado da arte da alimentação durante a larvicultura do Macrobrachium amazonicum

Abstract

Macrobrachium amazonicum is a species native to South America having importance in the North and Northeast regions of Brazil, this species is very accepted by consumers due to its flavor and nutrition, having great potential for cultivation. Larviculture of this species lasts around 20 days, and in order to achieve success in this production it is necessary to establish an adequate diet in an economical and highly nutritious way for the larvae. The most used foods at this stage are brine shrimp and inert diet. Factors such as light and coloring of the culture tanks can influence feeding, growth and survival. Thus, the objective of this work was to survey the state of the art regarding the relationship of food and how with factors influence food consumption and, consequently, development and survival of larvae of M. amazonicum. This work was carried out through a review of literature, articles and books, which took place from the Google Scholar and SCIELO databases. The review was carried out from April to August 2021. In total, 312 articles were found, 261 in Google Scholar and 48 in SCIELO, which following the inclusion and exclusion criteria, 10 articles were selected that contributed to this work. Based on the results of the studies found, it can be concluded that the use of nauplii from stages II to IV can be efficient and economical, and from stage V onwards, the complementation with the inert diet, the best period for feeding should be during the day. White tank favors the best larval performance, and black tank promotes better survival and productivity.
