At that time, the classification of tiger fish species was not as clear as it is today. which is currently classified into 3 species : Coius microlepis, C. pulcher, C. undecimradiatus, if based on the current classification Tiger fish being farmed at that time were of all 3 types, but the fry that were produced at that time were C. undecimradiatus. The fry that were bred were raised to become parents. There are also ongoing studies on raising tiger fish, such as trying to raise tiger fish with live food and non-living food (published), trying to raise tiger fish in cages inside earthen pond. (Unpublished) found that fish grew faster than those kept in glass tanks and cement ponds. The reason why this project was discontinued at that time was because the researcher was a government official. and has moved to work in another province And the conditions for doing research (at that time) were that when moving to work in another province, they would not be able to do research on tiger fish in other provinces. (Do research according to the type of local fish species in each province/region). As for the reason that the tiger fish has become extinct, it is because it is a highly prized fish and has been taken and exploited by fishermen in quantities that exceed production capacity. Natural production that will be able to produce a new generation of population to replace it in time. Large fish are caught and sent to restaurants because of their good taste. It is popular to consume. Small fish are collected and sold abroad as ornamental fish. And legal measures are not keeping up with the situation in which the tiger fish species should be preserved so that it does not go extinct. However, At present, the responsible agency is continuously studying the breeding of tiger fish.
