Abstract

The present study was performed to analyze the economic importance and determine the effect of constant light (LL) and constant dark (DD) on weight of the animals in different time interval of the year 2019, 2020 and 2021 in Indian fish Clarias batrachus. The fingerlings of C. batrachus were collected and harvested in a pond. The fishes were fed with rich protein content feeds. Weight of sampled fish was measured. The fishes were acclimatized to work place before conducting the experiment. They were divided into three groups each contacting 48 fishes and maintained under photoperiods of natural day-night (control), LL and DD for 60 days. The experiment was performed for during different phases of C. batrachus reproductive cycle i.e., resting, pre-monsoon, monsoon, and post monsoon for three consecutive years. Four fishes from each group were examined during the experiment at every 15 days to take the body weight of animals. Results were analyzed using ANOVA for four different factors including “Year” (1, 2 and 3), “Treatment” (normal day-night, LL, and DD) “Phase” (resting, pre-monsoon, monsoon, and post monsoon), and “Time interval” (15, 30, 45 and 60 days) on body weight of C. batrachus. Increased body weight was seen DD group as compared to control group. LL has also shown increased body weight but lesser that DD group. It can be concluded from the study that under DD condition body weight of fishes increases and their economic value can be increased by proper farming and maintenance.

Conclusion

C. batrachus is a highly demanded and economically important fish species. The nutritious value of catfish is very useful and rich source of protein and nutrients. Increase weight of catfish was observed in DD during pre-monsoon and monsoon phases. Thus, proper farming and maintenance of C. batrachus may grow the market and enhance their economic value.
