[Parenting] Male fish characterized by female wastewater

Without thorough control over chemicals, it has been argued that male fish in rivers can turn into females.

Professor Charles Tyler of the University of Exeter in the UK said he was concerned about the negative consequences of irresponsible waste management.

Toxic substances are released through the drain without regard to the home and industry.

Tyler participated in the major marine biology research conducted in 2008. In this study, one-quarter of the male roach fish caught in 51 areas of the UK rivers showed female signs as if they had oocytes in the testicles.

All male loch fish have been found to be femaleized due to extreme levels of estrogen, explained Tyler because certain contraceptive chemicals have flowed into the river.

Still, many people do not understand that marine life is suffering from irresponsible chemical and waste management.

According to Tyler, about 200 male fish have been femaleized. This means that males can not successfully lead to the next generation of genes. Chemical waste does not actually kill fish, but the sex ratio is unbalanced and the population declines over time.

"Wildlife populations are exposed to multiple stresses," Tyler said.

"If the adverse effects on chemicals and population are proven, we have to be more aggressive in responding to restrictions or restrictions on chemicals," he added.

Tyler will speak on this issue as a symposium speaker on the 50th anniversary of the Fisheries Society in the British Isles.
