ThesisItem Open Access Comparative study on the effect of papaya, banana and pointed gourd fruit on growth and reproductive profile of Amur Common Carp(G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-06) Tomar, Pallavi Singh; Ram, R.N.The present study was carried out to compare the effect of papaya ,banana and pointed gourd fruit on growth and reproductive profile of amur common carp for period of 180 days .A total of 168 fishes of average weight of 135g divided into four groups of 42 fishes each viz. Group C1 (Control), Group T1(2%Banana fruit),Group T2(2%Pointed gourd fruit),Group T3(2%Papaya fruit).A total of 48 fishes stocked in 3 tanks with 14 fishes per tank. After one week of acclimatization period, banana, papaya and pointed gourd was given in pellet form twice a day at the rate of 2% each in a divided dose at a rate of 5% of the fish's total body weight till 180 days post group (DPT) to groups T1,T2 and T3.In this study Growth and reproductive profile histological parameters studied at different interval i.e.,0ͭʰ,30ͭʰ,60ͭʰ,90ͭʰ,120ͭʰ,150ͭʰ,180ͭʰ DPT. The best results for growth parameters like mean weight gain (318±1.15g),mean length gain (37±.57cm),lenght weight relationship (174±3.88) Since the value of regression coefficient (b) is less than 3 over the course of the entire experiment for each group at each time interval, growth is allometric, condition factor (1.82±.03), specific growth rate (0.2±.004%)and for morphometric study of ganoad and liver the best reault for gonadosomatic index of male(9.89±.42%) and hepatosomatic index in females and males (3.7±.07% and 0.8±.04% )respectively were recorded in group T1 in comparison with the group C1 (control) .According to the findings of this study, groups fed with banana @2% (T1) produced superior results than their counterparts. The findings show that all three fruits had no negative impact on the physicochemical qualities of water, allowing the fish to be less stressed and perform better physiologically. Histologically, there were no notable alterations in the liver, muscle, ovary, or testis of the Control group C1. The liver parenchyma showed considerable vacuolar degeneration of hepatocytes at all time intervals in the T1, T2, and T3 groups. Despite the fact that group T3 on the 30ͭʰ, DPT indicated fragmentation in many muscular fiber bundles, muscle fiber loss also occurred, resulting in the creation of space. A considerable reduction in the size of the muscle fiber bundle was seen on the 60th DPT. On the 120ͭʰ, DPT, the muscle fiber bundle had severe fragmentation and necrosis. A significant hemorrhage was observed in T3 group on the 60th DPT in ovary. In testis no significant changes were observed in any of the groups, T1, T2, or T3, at any time interval between the 0th and 180ͭʰ DPT. As a result, it is suggested that the efficacy of banana as a growth enhancer be investigated as a cost-effective, readily available, and environmentally friendly package for enhancing aquaculture productivity.
