“…This result is consistent with a study of a carnivorous freshwater specie (Pseudoplatystoma sp.) reared under similar conditions of commercial aquaculture (Honorato et al, 2015). However, higher yields of 47-50% were recorded by Fogaça, Oliveira, Carvalho, and Santos (2011) evaluating pirarucu juveniles of 7-16 kg BW.…”

Pirarucu (Arapaima gigas) is a fast-growing, carnivorous species reared commercially in Amazonian countries as Brazil. Lack of a nutritionally balanced and affordable diet is a major constraint in pirarucu aquaculture, and our investigation sought to estimate the dietary protein requirement for this species. Four diets were formulated to contain increasing concentrations of digestible protein (32, 35, 38, and 41%) and fed to triplicate groups of juvenile pirarucu of around 2 kg for 18 weeks. As result, pirarucu showed no differences in feed intake, survival, or fillet yield. However, regression analysis revealed that weight gain (WG) values showed a general increasing trend with increasing dietary digestible protein (DP) level up to 36.7%. In addition, feed conversion rates were also improved with increase in dietary DP up to 36.4%. Fish fed diets containing 32 and 41% had poor feed conversion rates. Thel protein retention rate (PRR) and protein efficiency index (PER) decreased as levels of DP increased. The optimal dietary protein content for juvenile pirarucu between 1.98 and 4 kg of BW is about 36% of digestible protein on diet.

“…In this study, the similarity between the treatments for HSI shows that the protein content of the diets was not used to meet the jundiaras' energy needs. Honorato et al (2015) reported that levels of crude protein up to 40% in the diet did not influence the HSI of surubin (Pseudoplatystoma sp).…”

“…The similarity of the survival rate among the experimental treatments showed that this variable was not influenced by the different crude protein levels of the diets. According to Honorato et al (2015), the causes of decreased survival rates of native species in aquaculture systems are generally associated with management errors, environmental factors and the quality of water used in the production process.…”

“…These species include Pseudoplatystoma fasciatum (Linnaeus, 1766), popularly known as surubim, which is found in the Amazon, Prata, and São Francisco basins. This species has two factors that limit its breeding in a production system: the difficulty of feeding with inert feed and high rates of cannibalism in the larval and post-larval phases (Cornélio et al, 2014;Honorato et al, 2015).…”

The objective of this study was to determine the crude protein requirements for juvenile jundiara fish, a hybrid of Pseudoplatystoma fasciatum X Leiarius marmoratus. A total of 240 juveniles of the hybrid, with an initial mean weight of 8.4 ± 1.41 g, were distributed in 15 fiberglass tanks (170 L) in a closed water recirculation and constant aeration system, with a density of 16 fish/tank. The experimental design was completely randomized with five treatments and three replications. The treatments consisted of diets with 32, 34, 36, 38 and 40% crude protein. Seventy days into the experiment the final fish weight and feed intake were measured. Two specimens from each experimental unit were collected for evaluation of carcass chemical composition, nutritional efficiency and blood parameters. The increase in crude protein content promoted the significant, increasing linear effect for mean weight gain, mean feed intake and specific growth rate, and decreasing effect for feed conversion. Significant differences were also observed in carcass chemical composition, nutritional efficiency, total plasma protein, glucose, cholesterol, triglycerides and lipase enzymatic activity. Thus, the increase in crude protein levels of up to 40% in jundiara diets promotes improvement in the productive performance of juvenile jundiara.

“…Ainda seria possível aumentar essa taxa de sobrevivência em até 25,0% passando para 81,80%, com melhora na CAA em 20,1% e na BE em 14,6%. É relevante destacar a importância desse cenário, uma vez que esses indicadores zootécnicos e econômicos podem ser obtidos no setor produtivo, com valores ainda superiores, como demonstrado em outros trabalhos utilizando surubins em diferentes sistemas de produção(HONORATO et al, 2015;SABAINI;CASAGRANDE;BARROS, 2015; FANTINI et al, 2017).…”

Objetivou-se com este trabalho obter investimento de implantação de uma piscicultura com 27 ha de lâmina d'água ecusto de produção de espécies nativas em sistemas de policultivo e monocultivo, de forma analisar economicamente a viabilidade do sistema de produção. A piscicultura foi implantada no estado de Mato Grosso onde foram construídos três tanques, dois com 6,2 e 11,0 ha de lâmina d'água que foram utilizados em seu primeiro ciclo de produção em sistema de policultivo com Tambatinga, Pintado da Amazônia e Piauçu, e um tanque de 9,8 ha usado com monocultivo de Matrinxã. Foram coletados dados mensalmente in locodos itens de investimentos, despesas e controle Palavras-chave: indicadores zootécnicos. peixe redondo. surubim. viabilidade econômica.
