Sakar Fish: An Aquarium Fish that Threatens Fish Farmers

Sakar fish is a common name for a type of catfish that belongs to the family Loricariidae. The scientific name of this fish is Hypostomus plecostomus. This fish is native to Brazil and is popular as an aquarium fish because it can clean the tank by eating algae and other waste. However, this fish has also become an invasive species in many countries, including Bangladesh, where it poses a threat to fish farmers and native fish species.

Introduction of Sakar Fish in Bangladesh

Sakar fish was first imported to Bangladesh in the 1990s as an aquarium fish. Some local aquarium traders and hobbyists started to breed this fish for commercial or personal purposes. However, some of them may have released this fish into open water bodies either accidentally or intentionally. This fish can also escape from ponds or tanks during floods or heavy rains. As a result, sakar fish has spread to various rivers, canals, lakes, and reservoirs in Bangladesh.

Impact of Sakar Fish on Fish Farming and Biodiversity

Sakar fish is a harmful fish for fish farming and biodiversity because it can compete with native fish for food and space. Sakar fish can eat aquatic plants, algae, small fish, snails, insects, and other organic matter. It can also damage the nets and cages used by fish farmers by biting them with its sharp teeth. Sakar fish can reproduce rapidly and can survive in harsh conditions. It can live up to 24 hours without water and can breathe air through its skin. It can also grow up to 16-17 inches long and weigh up to 2 kg.

Sakar fish has reduced the production and income of many fish farmers who depend on open water bodies for their livelihood. It has also affected the diversity and abundance of native fish species that are important for food security and ecosystem health. Sakar fish has no commercial value or demand in Bangladesh as it is not considered edible or tasty by most people.

Conclusion

Sakar fish is an aquarium fish that has become an invasive species in Bangladesh. It has caused problems for fish farmers and native fish species by competing with them for food and space and damaging their equipment. Sakar fish has no economic or ecological benefits for Bangladesh and should be controlled or eradicated before it causes more harm.
