Appropriate stocking density of common lowland frog (Rana rugulosa, Wiegmann, 1935) in cage culture in the Winter Season

Abstract

The objectives of this study were to appropriate stocking density of common lowland frogs in cage culture in the winter season on growth rate and survival rate of common lowland frogs in cage culture in the winter season from January to February in 2020. A total of 3,000 common lowland frogs were allotted to four experimental groups with three replications in a Completely Randomized Design. Four experimental groups consisted of stocking density at 100, 200, 300 and 400 individuals in 1 square meter (m²), respectively. The results found that the growth of common lowland frogs in body weight and body length, feed conversion, survival rate and average daily weight gain were statistically significant difference (p<0.05). The 100 individuals/ m² of common lowland frogs in cage culture during winter season showed higher growth performance than other experimental groups. The average of body weight, body length, survival rate and daily weight gain of 100 individuals/m² of common lowland frogs were 68.29±8.45 g, 8.28±0.30 cm., 64.00±4.35 % and 1.05±0.13 g/day, respectively. Therefore, this study identified that the optimal population of common lowland frog in culture cages was 100 individuals/m² during winter season.
