Hidrolisado proteico de peixe em dietas para juvenis de Arapaima gigas

Abstract

This study evaluated the dietary inclusion of a fish protein hydrolyzate (FPH) derived from tilapia trimmings on physiological and growth parameters of juveniles of Arapaima gigas. A total of 180 arapaima juveniles (91.4 ± 2.7 g) were used in a complete randomized design with six treatments (n = 3). Fish were fed to apparent satiation four times a day for eight weeks, with diets containing increasing inclusion levels of FPH (0, 4, 8, 12, 16 and 20%). FPH diets did not affect growth and hemato-biochemical parameters of arapaima juveniles. The FPH from tilapia trimmings seems to be a suitable ingredient for arapaima over 90 g, feeds at least up to 20% inclusion level. No bioactive effects of the FPH could be detected.

Ameliorative Effects of Different Dietary Levels of Fish Protein Hydrolysate (FPH) on Growth and Reproductive Performance, Feed Stability, Tissues Biochemical Composition, Haematobiochemical Profile, Liver Histology, and Economic Analysis of Pabda (Ompok pabda) Broodstock

“…The RBC is crucial for oxygen transport throughout the body, ensuring proper tissue function. In addition, earlier studies discovered that various levels of protein hydrolysate supplementation in fish diets affect the HGB, HCT, MCV, MCH, and MCHC levels, similar to the current study findings [75,76,[78][79][80]. These are essential parameters in an aquaculture species as indicators of health and physiological status.…”

“…Monocytes are responsible for pathogen phagocytosis and assist in immune response, eosinophil modulates inflammation, and basophil contributes to allergic reactions in fish. Earlier studies also reported similar outcomes with various levels of FPH in Arapaima gigas [75], Penaeus monodon [76], and O. pabda [1].…”

Physiological responses of tambaqui (Colossoma macropomum) fed diets supplemented with silage from fish and vegetables residues

“…This increase in triglycerides may be linked to high amounts of carbohydrates in the diet related by Silva et al (2020), which was not found in the present study. Ribeiro et al (2017) did not observe changes in the hematological and biochemical parameters of A. gigas fed for 60 days with diets with up to 20% inclusion of the fish protein hydrolysate and suggested this formulation as an adequate supplement to the diet of these fish.…”
