“…This result was in harmony with that of Melo BJF, Abdel-Tawwab M [26,39] who reported that, serum protein increased with increased dietary protein level. Also [40] stated that, the increased protein level in diet leads to rise of serum protein which could likely be due to the enhancement of digested protein.…”

The present investigation was conducted to assess the effect of different dietary protein percentages and starvation on the health, behavior, blood chemistry, immune response and histoarchitectures of fan tail gold fish Carassius auratus L. Experiment was carried out using 80 Carassius auratus with an average body weight 18 ± 2 g which were divided into four groups in duplicate in which, group 1 feed with diet A; 28% Crude Protein (CP). Fish in group 2 was fed on diet B (17% CP) and fish in group 3 was feed on diet C (45% CP) and group 4 kept as fasted group. The experimental period was 8 weeks. The current study clarified that significant high growth rate, improved welfare; decrease aggressive behavior, improved biochemical serum parameters and immune response were observed in group feed with diet containing 45% crude protein. Starvation is directly affected health, immunity and welfare as well as histoarchitectures of all selected organs. Histologically, there is no any significant changes on the histoarchitectures of the all selected organs; liver, spleen, intestine, head kidney as well as muscle of groups 1, 2 and 3 feed with diet A (28% CP), diet B (17% CP) and diet C (45% CP) respectively. Meanwhile, the fasting of group 4 had the most effective changes on the histoarchitectures of all selected organs.

“…Meanwhile, fish growth largely relied upon protein deposition, which was mainly associated with the amino acid metabolism [57]. GOT and GPT are the most important amino acid-metabolizing enzymes [58] and the improvement of muscle and liver GOT and GPT activities reflected the increase of the amino acid metabolism in fish [59]. The present study showed that dietary proteins increased young grass carp muscle and liver GOT and GPT activities.…”

The objective of this study was to determine crude protein requirement for Hypostomus commersoni fingerlings. Seventy two fingerlings of armoured catfish were used with average weight of 2.44 ± 0.14g, distributed in nine tanks, totalizing eight fish per experimental unit. In a completely randomized design, with three treatments and three replications. Three experimental diets were prepared with protein levels of 25, 30 and 40% and isocaloric (3.500 kcal. kg-1). The fish were fed daily with at the rate of 5% of body weight for 10 weeks. Evaluated variables were final average weight, weight gain, specific growth rate (SGR), survival and body composition. Dietary levels of protein did not affect weight gain, specific growth rate and survival. Crude protein higher levels in the diet increased the deposition of protein and reduced body fat (p≤0.05). Levels of 25% crude protein in the diet of armored catfish are suffi cient for good growth performance, however, raise levels may be beneficial, increasing protein deposition in the carcass and reducing body fat.
