Abstract

The goal of the current study was to determine how a mineral mixture specifically designed for fish affected their growth, nutritional makeup, and overall health of Cyprinus carpio. The experiment consists of five treatments (T1-T5, in triplicate); the basal diet used for all the treatments consisted of rice bran (49-50%), mustard oil (48.5-49%), mineral mixture (0 2%) and salt (0.5%); the positive control with commercially available mineral mixture (T1) and the negative control without any mineral mixture (T2) and three (T3-T5) treatments supplemented with formulated mineral mixture (as per ICAR, 2013 recommendations) at three inclusion levels of 1%, 1.5% and 2%, respectively. All the major water quality parameters were within the acceptable limits. When compared to the non-supplemented group (T2), the growth performance of C. carpio fingerlings, including final weight, weight gain, and specific growth rate, has been significantly (P<0.05) improved by the developed mineral supplementation. Additionally, the T4 group’s feed conversion ratio and protein efficiency ratio were shown to be much improved (p<0.05). Moreover, the total protein and fat content of the flesh were significantly (p<0.05) boosted by the mineral mixture. Haemoglobin, haematocrit, total erythrocyte count, total leucocyte count, mean corpuscular volume, mean corpuscular haemoglobin, and mean cell haemoglobin concentration were considered as responsible parameters for haematological study and were also significantly (P<0.05) improved and best recorded at 1.5% (T4) mineral mixture compared to the non-supplemented group. The information gathered for this study will help a number of stakeholders, including fish farmers, entrepreneurs, and the feed sector, increase fish production and productivity in a sustainable manner.
