The United Nations has warned in a report on Monday that a third of the world’s oceans are overfished and fish consumption is at an all-time high.
The U.N. Food and Agriculture Organization (FAO) report said this has increased fears over the sustainability of a key source of protein for millions around the world.
The report said overfishing is particularly bad in parts of the developing world where many people already struggle to get enough nutritious food to eat.
“There’s too much pressure on marine resources and we need significantly more commitments from governments to improve the state of their fisheries,” Director of the FAO Fisheries and Aquaculture Department, Manuel Barange, said.
“We predict that Africa will have to import fish in the future,” he told the Thomson Reuters Foundation, adding that shortages could lead to higher prices, disproportionately affecting the poor.
Barange said Africa had great potential for aquaculture, but needed support in terms of finance, feed and supply of fish.
Fish farming or aquaculture – the fastest growing agricultural sector for the past 40 years – has been largely responsible for making more fish available, said the report.
As catches from the open sea continue to dwindle, more countries are turning to fish farms. In Algeria, the government is encouraging farmers in the Sahara desert to grow fish to increase their income and boost fish production.
Critics say it can damage the environment and put disease and invasive species into the wild, but Barange said the solution was to have “proper regulation, legislation and monitoring and control”.
Traditional fishing nations are also promoting the potential of fisheries to improve nutrition and end hunger.
Globally, the percentage of stocks fished at unsustainable levels increased to 33.1 in 2015, from 31.4 in 2013 and 10 in 1974.
Fish consumption reached an all-time high of 20.2 kg (44.5 lb) per person from 9 kg in 1961, said the report, and further rises are expected as health-conscious consumers turn to fish.
Currently, 3.2 billion people rely on fish for almost 20 percent of their animal protein intake.
Shakuntala Thilsted, research programme leader at international non-profit World Fish, said reducing losses and waste would go a long way towards making fisheries sustainable, with an estimated 35 percent of catches thrown away.
“Fish heads, fish bones are (the) parts that are most nutritious. Why aren’t we using innovative solutions to turn this into nutritious, palatable food?” she said.
