Conclusion
Lampam (Barbonymus schwanenfeldii) is a freshwater fish mostly found in tropical and sub-tropical water regions like Malaysia. It possesses high commercial significance in Malaysia due to its delicious meat, and strong demand that led many researchers to investigate its biological and feeding behavior to improve its growth and population dynamics. This study aimed to determine the survival rate, growth rate, and FCR of B. schwanenfeldii (Lampam) through treating them with three different types of protein diets, TP0 with 31% protein content, TP1 with 28% protein content and TP2 with 23% protein content. In this 90 day experiment, it is found that Lampam fish showed significantly different growth rates (P<0.05) when provided with different protein diets. The highest growth rate was observed with the highest protein containing diet TP0 which indicated that a high protein rich diet with appropriate amino acid ratio enhances the growth and development in Lampam fish. High growth is directly proportional to increased metabolic rate and high FCR. The present study has indicated that the Lampam fish can be cultured in the proteinaceous diets with 31% protein content while the effect of diet was not observed considerably significant for the survival rate amongst all the three diet treatments. These findings have also been parallel to other previous studies that emphasized the role of protein-rich diet for the development of B. schwanenfeldii.
The other critical water parameters were also analyzed in this study like water temperature, pH and DO, and their values were maintained in the following range between 24-26 ºC, 5.9-6.8 pH and 0-7.2 mg/L respectively. The results of the study showed that other water parameters did not impact the growth and FCR of the B. schwanenfeldii. On the other hand, previous research claimed the powerful effects of water parameters on Lampams’ growth that indicated the probability of any incorrect data calculation in this study. It emphasizes the requirement of a more in-depth analysis to investigate the biological behaviors of Lampams.
Overall, this study has provided valuable insights regarding the biological and physiological behavior of Lampam fish. It will assist in understanding the Lampams’ life history, growth rate, survival rate, metabolic rate, FCR, and mortality. Thus, the findings of this study will help in growth, and preservation as well as in the sustainable development and efficient meat improving practices of this commercially important fish species.
