According to Australian abc TELEVISION reported on August 8, in Tasmania, Australia, delvement River and nearby bay bottom, living a spotted warty fish, also known as spotted long handfish, they are a kind of "walking" fish, long fins, very rare, is the world's first marine species listed as endangered. Under the bed of the Derwent River lie many discarded beer bottles, which is generally a pollution to the river, but scientists have found that these beer bottles seem to be able to help the breeding of spotted warts and play a beneficial role.
Senior researcher Tim Lynch said that spotted warts prefer a more complex breeding habitat, and those discarded beer bottles can be used as an ideal breeding site for them. Since the 19th century, people on ships have thrown glass bottles into the water, and these bottles that have fallen into the water have always been regarded as a pollution, and they have not expected to become a breeding place for spotted warts.
Over the past 10 years, Tim and many scientists, along with volunteers, have placed about 6,000 plastic rods on the riverbed so that spotted warts can safely lay their eggs in these artificially created environments. Tim says there are already a variety of programs to help spotted warts lay eggs, and some related agencies have raised nearly $40,000 to start a captive breeding program.
According to the scientists' observations, the spotted warts reproduce well in captivity, and then they will release these fish into the wild, each female laying about 200 eggs at a time, and the mother fish will take care of the eggs until the eggs hatch. In the past, spotted warts were not uncommon, they were very common, and there would be a spotted wart every 5 meters of water.
