The objective of this study was to evaluate meat yield and centesimal composition of the Amazonian fish species, A. ocellatus, P. castelnaeana, and L. friderici, in the dry and flood seasonal cycles of rivers. In each seasonal cycle (flood and dry), a total of 60 fish were collected, comprising 20 specimens of each of the following species: A. ocellatus, P. castelnaeana, and L. friderici. Were evaluated the meat yield, cuts yield and centesimal composition of the fish samples. Meat yield in the clean body cuts and skinless filet varied between species and hydrological period. The results showed that seasonal variation influenced the centesimal composition and yield of the species studied, with significant differences between the cuts produced during processing. These findings highlight the need to apply a variety of technological processes to ensure efficient use of these species throughout the year. The total waste represented more than 50% of the whole fish, and the head size was directly proportional to the amount of waste generated. These results underscore the importance of waste utilization for animal and/or human nutrition.
Resumo -Ao considerar a expansão da piscicultura do tambaqui (Colossoma macropomum) nas regiões Norte, Nordeste, Centro-Oeste e Sudeste do Brasil, a busca pela eficiência dos seus procedimentos faz-se necessária no atual cenário competitivo. O mapeamento e envolvimento dos atores dessa atividade mostram-se imprescindíveis para a reorganização e a concepção de um processo produtivo no contexto de cadeia produtiva. Nesse sentido, este artigo, ao levantar o estado da arte atual sobre os principais entraves da piscicultura desenvolvida no estado do Amazonas, aponta a necessidade da criação de um modelo logístico de transporte intermodal, aproveitando, assim, as características naturais da região em estudo. O artigo inicia-se contextualizando a atividade de pesca do Amazonas, segue com a descrição da cadeia produtiva do peixe, bem como com a caracterização da piscicultura do tambaqui no estado, e termina com a reflexão acerca da logística de distribuição dessa cadeia valendo-se de uma plataforma logística intermodal. Palavras-Chave:aquicultura, Colossoma macropomum, plataformas logísticas, produção de pescado. Abstract -Considering the expansion of theTambaqui fish (Colossoma macropomum) in the North, Northeast, Midwest and Southeast regions of Brazil, the search for the efficiency of its procedures is necessary in the current competitive scenario. The mapping and the involvement of the actors of this activity are essential for the reorganization and conception of a productive process within the context of the productive chain. Given this context, this article presents the current state of the art on the main obstacles of fish farming developed in the state of Amazonas, as well as it points out the need to create a logistic model of intermodal transport, thus taking advantage of the natural characteristics of the region under study. The article begins with a contextualization of the fishing activity of Amazonas, followed by the description of the fish production chain and the characterization of the Tambaqui pisciculture in the state. The article is concluded with the reflection about the distribution logistics of this chain using an intermodal logistics platform.
