Among the frogs the Indian bullfrog Hoplobatrachus tigerinus is an important item. It is an important delicious food items especially its leg to many people especially tribal people in Europe and Asia. Some people of Bangladesh used to catch and export frog legs to abroad. It plays an important role in the ecosystem, i.e. controlling of various agricultural pests. H. tigerinus consumes agricultural pests as they are insectivore. Due to climate change the availability of food of the insects are decreasing and they become attracted to higher plants. Frogs mainly H. tigerinus can play a major role in this respect as because it is an insectivore. Once H. tigerinus species was available in the diversified waterbodies of Bangladesh. But the availability of H. tigerinus is going to be decreased due to different anthropological effects and environmental changes. The reasons for their decrease in the nature are indiscriminate harvesting, habitat degradation, aquatic pollution and several other causes. Presently this species is regarded as endangered from the biodiversity point of view (IUCN, 2000).
