Abstract

Many people have a cultural practice of eating fish, and it has many health benefits. It is a good source of protein, fatty acids, vitamins, minerals, and other micronutrients. Fish has an outstanding nutritional profile and carps lack l-gulonolactone oxidase (EC 1.1.3.8), they are unable to generate vitamin C, which is necessary for fish growth from an exogenous source. In order to assess the effects of vitamin C, as l-ascorbate-2-triphosphate Calcium (LATP-Ca), on the physiology and growth, a 50-day feeding experiment was carried out on common carp (Cyprinus carpio). For six weeks, common carp (59 ± 0.56g) were kept in triplicate cemented tanks on four semi-purified diets (treatments A, B, C, and D, respectively) supplemented with 0, 1000, 1500, and 2000 mg/kg vitamin C, l-ascorbate2-triphosphate Calcium (LATP-Ca). Weight gain and weight gain (%), SGR, and FCR were assessed for growth study; quantification of vitamin C in the kidney, liver, brain, and muscles was examined, and then serum glucose, triglycerides, creatinine, and urea were examined for biochemical performances and total serum protein, albumin, and globulin as well as liver function tests such as SGOT, SGPT, and ALP after full hematology was examined to understand the immune-haematological performances. It was observed that dietary vitamin C levels had a substantial (P < 0.05) impact on weight increase, weight gain %, specific growth rate, and tissue vitamin levels. While FCR, SGOT, SGPT, serum glucose, cholesterol, triglycerides, creatinine, and blood urea concentration level showed declining trends. Additionally, a complete blood hemogram profile and vitamin C were found to interact significantly, with the LATP-Ca treated group exhibiting improved performance. The effects of vitamin C on carp growth, physiology, and immune response are demonstrated by the treated group’s superior blood cell morphological structure as compared to the control group. In conclusion, dietary vitamin C (LATP-Ca) at inclusion levels of 1500 to 2000 mg/kg enhanced carp development and shielded fish from growth, depression, and mortality.
