چکیده

A 110-day feeding trial on marron (Cherax cainii) evaluated the effects different protein sources on the growth, immunocompetence, and tail muscles amino acid profile. Four animal-protein-based diets—poultry by-product meal (PBM), black soldier fly meal (BSFM), tuna hydrolysate (TH), and fishmeal (FM)—and two plant-derived protein diets—lupin meal (LM) and soybean meal (SBM)—were tested. A total of 450 marron were individually placed in containers and distributed into 18 tanks, representing six dietary treatments in three replicates. The results demonstrated that marron fed BSFM and FM diets obtained significantly higher (P<0.05) weight gain (WG) and specific growth rate (SGR) values (73.18–81.86% and 0.65–0.67%/day, respectively) than other diets. There were no significant differences in survival or net biomass increment. Marron fed BSFM showed the highest moult increments (MI) and the shortest intermoult periods (Tim), while TH and LM resulted in the lowest. The BSFM diet also led to the lowest hepatopancreatic moisture. The total haemocyte count and granular cells proportion in marron fed TH were lower than those in marron fed other diets. Protease activity was lower in marron fed TH and LM than other protein sources. Except for methionine, amino acid profiles in the tail muscle of SBM-fed marron were similar to those in FM, PBM, and TH groups. Marron fed TH and LM showed an enlargement of tubular and intertubular spaces within epithelium in the hepatopancreas, myodegeneration in tail muscles, and shorter fold height and width in the marron intestine. In conclusion, FM, PBM, and BSFM protein-based diets promoted the growth, immunity, and hepatopancreatic health of marron, while TH and LM diet resulted in decreased growth. SBM did not significant impact growth. The results would contribute to using local protein ingredients as replacement for fishmeal protein for the development of marron industry in Western Australia.
