Methods for preventing and controlling common predators in toad farming

(1) Prevention and control of tadpole predators 1. Types of predators    Carnivorous fish, turtles, shrimp, rice field eels, water snakes, water centipedes, leeches, aquatic plankton, etc. In addition, large tadpoles eat small tadpoles, and young toads and adult toads eat small tadpoles.

2. Prevention and control methods   (1) Before stocking tadpoles, disinfect the pond, or use a fine-mesh net to pull-catch once. (2) Filter the water inlet and drainage outlets with metal mesh or gauze. (3) Regularly disinfect the pond water. (4) Stock large and small tadpoles in separate ponds. (5) Manually remove or use copper sulfate solution (0.7-1.4 grams of copper sulfate per cubic meter of water) to kill filamentous aquatic algae. (2) Prevention and control of predators of young toads and adult toads  1. Types of predators  Carnivorous fish, snakes, turtles and soft-shelled turtles, rodents, otters, leeches, and some flying birds. Toads themselves can also cannibalize each other. 2. Prevention and control methods   (1) Strengthen wall isolation and protective facilities. (2) A shed frame or gauze net can be set up above the breeding site. (3) For leeches, use 400-500 grams of MIPC per 667 sq m, mix with 50 liters of water, and spray with a sprayer, or mix with 200 liters of water and pour it on to poison and kill them. (4) Disinfect the pond. (5) Add filter nets to the water inlet and drainage outlets. (6) Trap or lure-kill rodents.
