Marvel at fish that can live 6 days on land

Scientists warn that a freshwater pelagic fish capable of living in saltwater and terrestrial waters for up to six days will become a "threat" to Australian native creatures once they arrive. land.

Fish can live 6 days on land

According to marine ecologist Nathan Waltham, he and his colleagues at James Cook University discovered this type of perch in saltwater pools during an expedition to the islands in December 2014. This triggers a warning bell, so in the dry season, the water in the wetlands has a very high salt density, twice the amount of salt in the seawater, but this fish can still survive. However, Dr. Waltham identified the possibility that they could swim across the ocean to reach the mainland. The higher risk is that they "go " to fishing boats or get caught in the net and be discarded.

Dr. Waltham said the fish can breathe on the ground, crawl on the ground by gill and fins , dormant in mud for 6 months and salt water is not a problem for them. The range of movement of these Southeast Asian species is enormous, they have spread throughout Indonesia, Java and Papua New Guinea in just four decades. This freshwater fish was discovered at the end of 2005 on Boigu and Saibai Island, two northern Australian outposts, less than 10 km from Papua New Guinea and 160 km from Cape York of Australia.

With hard pairs, this perch is a threat to native carnivorous fishes . Scientists discovered seabass (barramundi) and catfish on Boigu Island and Saibai died from eating these animals and were infected in the neck. In addition to fish, birds can also be victims of this creature. With high tolerance, they can thrive in harsh living conditions, affecting the survival of many other aquatic species.

Dr. Waltham's team is currently testing this fish's tolerance to saltwater, lack of air and unusual temperatures to find ways to control the number of these species and predict migration trends. their residence.

If they reach the land, the fish will appear in the list of invasive species from Papua New Guinea, which has recorded white catfish, fruit fish, pacu fish, tilapia and giant earfish. Threatened species of Australian native creatures.
