The National President, Catfish and Allied Fish Farmers Association of Nigeria (CAFFAN), Dr Momoh Mustapha, said that global warming and halocene extinction is a threat to fishing activities in the world.
Mustapha said this in an interview with the News Agency of Nigeria (NAN) in Abuja on Sunday.
He said that global warming which is the gradual increase in the overall temperature of the earth’s atmosphere would definitely affect fish production.
“Water temperature directly affects the fish immune system and metabolism. Water temperature above 25 to 30 °C will negatively affect fishes.
“Global warming of the earth can adversely affect production capacity and the yield.
“If not controlled, it can reduce the production quantity and quality of fishes,” Mustapha said.
He said that proper knowledge on water chemistry is the solution to global warming.
Mustapha said that the holocene extinction, otherwise referred to as the sixth mass extinction or anthropogenic extinction, is an ongoing extinction event of species.
“As explained earlier, anthropogenic activities such as oil spills on water, agricultural runoff, industrial discharges and so on, are the major causes of the recent extinction.
“As the world’s population keeps growing, the human consumption rate will be higher, there may be serious environmental threat to the persistent civilisation,” he said.
Mustapha said there is need to grow more species of fish, and produce more food to sustain the ever growing population in the world.
