Producción sostenible de rana toro (Lithobates catesbeianus) con agua de reúso de un sistema Biofloc

In Mexico, bullfrog (Lithobates catesbeianus) production is carried out in only 35 animal production units, and improvements in its commercialization are necessary to increase demand. Faced with these challenges, innovative technological options such as Biofloc are emerging, which improve production efficiency in favor of environmental, economic and social sustainability. Thus, this study measured the effect of using reused water from a Biofloc system for tilapia (Oreochromis niloticus) culture in the intensive production of bullfrogs (Lithobates catesbeianus). With a biological material of 4,000 organisms (Lithobates catesbeianus), treatments were evaluated: T1 (drinking water), T2 (30% Biofloc reuse water), T3(60% Biofloc reuse water) and T4 (90% Biofloc reuse water); the variables Weight Gain (WG), Specific Growth Rate (SGR), Survival Percentage (%S), Survival Rate (SR) and Feed Conversion (FC) were measured. The results were analyzed in SPSS Statistic version 27.0.0 with an ANOVA and Mauchly's test of sphericity. The results showed that intensive production of bullfrogs (Lithobates catesbeianus) with reused water from a Biofloc system of tilapia (Oreochromis niloticus) culture is feasible.
