Abstract
In commercial farming, growth performance is the most influential factor for achieving economic profitability.The effects of stocking density on the growth performance of juvenile bullfrogs cultured in continuous water-flow tank system on a commercial scale. 4,500 frogs were stocked at densities of 30 and 60 frogs/m2 with three replicate ponds for each density, with an initial weight of 1.7. Frogs were feed an extruded diet and cultured over 45 days. Student t-test, was used to evaluate the effect of culture density on growth parameters and to verify if b was significantly different from isometric growth value. The best growth corresponded to a density of 60 frogs/m2 (P – value = 2.2e-16). The densities did not influence the Absolute Growth Rate (AGR; P = 0.2843) or survival (P = 0.0779), but had a significant effect in feed intake (P = 0.0461), Apparent Factor Conversation Rate (AFCR; P = 0.0123), final weight (P = 2.2e-16), final length (P = 8.607e-08), and final biomass (P = 0.0472). The results of the length-weight fitting results and the t-test suggested negative allometric growth. The bullfrogs grew successfully at both densities but performance was better with a density of 60 bullfrogs/m2.
