Influence of Supplementing Dietary Herbal Concentrations on Growth and Survival of Red Tilapia (Oreochromis sp.) Juveniles

Abstract

This study aimed to determine and analyze the concentration of fish herbs optimal for growth and survival of red tilapia juveniles. The Complete Random Design (CRD) was used as the experimental study method with 5 treatments and 3 replications. The to the applied treatments as follows: A (control), B (concentration of fish herbs 25 ml Kg-1), C (concentration of fish herbs 50 ml Kg-1), D (concentration of fish herbs 75 ml Kg-1), E (concentration of fish herbs 100 ml Kg-1). Observed parameters were Specific Growth Rate (SGR), Feed Conversion Ratio (FCR), Protein Efficiency Ratio (PER), Survival Rate, and Water Quality. The results showed that highest SGR value were on treatment C (0,86%), treatment B (0,73%), treatment A (0,69%), Treatment D (0,68%), Treatment E (0,60%). The lowest FCR values were at treatment C (1,34), treatment B (1,56), treatment D (1,72), treatment A (1,79), treatment E (1,93). The highest PER value was on treatment C (0,54), treatment B (0,52), treatment D (0,44), treatment E (0,32). The optimum concentration of fish herbs for highest growth of red tilapia was 50 ml Kg- 1 fish herbs concentration treatment . The study highlights the efficacy of "herbal" which is an ancient tradition, used in some parts of India. This ancient concept should be carefully evaluated in the light of modern medical science and can be utilized partially if found suitable.
