Abstract

The climbing perch ( ) is a species of amphibious freshwater fish in the family Anabantidae and is widely found across the globe. This fish can survive without water for a short period by resting under the mud during dry seasons. They do aerial respiration using paired suprabranchial labyrinthiform organs. This fish was used as a biocontrol agent against mosquitoes in confined water bodies, including rice fields, as they can feed on insects at the water surface. The performance of monoculture Anabas in natural ponds and impacts on the consecutive carp culture in the same pond are evaluated in the present study. The average production of Anabas recorded was 1.39 Kg per m area of the pond with survival of 57.33%. The significant reduction survival percentage of carps was observed in the second crop. The 2 reduction in carp stock was observed due to the predation by retained Anabas of the previous culture. They resist the toxicity of sea seed cake once hidden in the pond bottom. They might have survived inside the deep layer of clay with the help of respiratory support of the labyrinth and were established later. The study confirms the opportunistic carnivore feeding behavior without other feeds. The study concludes that Anabas is a good candidate fish for places where water availability is an issue. Proper fencing around the ponds needed to check its movement out and through the land. When a different candidate species is planned for the subsequent crop, complete harvest, even from the deeper portions of the pond bottom, must be ensured to prevent surviving Anabas from feeding on the fingerlings of the next crop.
