Cork fish is also a fun fishing rod. With live bait in the form of insects or frog children, cork is relatively easy to lure. But the teeth are sharp and the strikes and pulls are strong, can easily break the fishing line. For rural communities, especially farmers, cork fish are very helpful in eliminating pests, for example: rice fields that are often inhabited by snails, often lead to crop failure, as a result of snails that often eat rice, especially at a young age.
However, this fish can also be very detrimental, that is, if it enters fish rearing ponds. Cork is very greedy to eat small fish, so it can spend fish that are kept in the pond, especially if the pet fish is still small. Reportedly, cork fish introduced have developed into disturbing species in Sulawesi and Papua because they destroy native fish species.
