Clover, a former environment editor of the Daily Telegraph and now a columnist on the Sunday Times, describes how modern fishing is destroying ocean ecosystems.
Furthermore, there is even an oversupply problem in the current market as technological innovations have allowed entire schools of bluefin tuna to be caught at the same time.
In West Africa, fishing agreements are made with European, US, and Asian fleets because money is needed to build basic infrastructure like schools and hospitals.
Most commercial fish come from the shallow seas of the continental shelves or the surface water of the open oceans.
Deep sea regulation inside each country's 200 mile limit is in its infancy, and it is non-existent in many places.
Stinting is the favoured method of management around those areas, where each vessel catches a limited amount of fish.
Yet, new fishing vessels, such as the Atlantic Dawn at over 15,000 tons, are being constructed due to entrenched business and political interests.
Celebrity chefs maintain those several restaurants and publish numerous cookbooks on serving endangered fish.
Purse seins up to 80 miles long sweep the oceans for tuna, but catch everything else in the area, including sharks, dolphins, and other fish.

Furthermore, fisheries have incentive to watch their neighbours, in case their fish stock declines and the value of their quota falls.
In order for intensive fishing to occur, 50% of the ocean must be protected so that marine life can be sustained.
The contemporary angler is equipped with technology such as sonar, fish finders, and global positioning systems.
The Marine Stewardship Council (MSC) is an agency that gives an independent certification of sustainability to fisheries.
Laws that should be implemented in the future: give fisherman tradable rights to fish, create marine reserves, give regional fisheries bodies real power as they are preserving the populations in their local area, and let citizens take ownership of the sea.
"[4] The British newspaper The Independent called it "persuasive and desperately disturbing," "the maritime equivalent of Silent Spring".
The film was shot over two years at locations in England, Alaska, Senegal, Tokyo, Hong Kong, Nova Scotia, Malta and the Bahamas, following author Charles Clover as he investigates those responsible for the dwindling marine population.
The film features Clover, along with tuna farmer turned whistle blower Roberto Mielgo, top scientists from around the world, indigenous fishermen and fisheries enforcement officials, who predict that seafood could potentially extinct in 2048.
Labelled "the biggest problem you've never heard of, The End of the Line illustrates the disastrous effects of overfishing, and rebukes myths of farmed fish as a solution.
The film advocates consumer purchases of sustainable seafood, pleads with politicians and fishermen to acknowledge the chilling devastation of overfishing, and for no-take zones in the sea to protect marine life.
Celebrity chef Jamie Oliver and Japanese restaurant chain Nobu have come under criticism for not taking tuna off the menu.
The Economist has called The End of the Line "the inconvenient truth about the impact of overfishing on the world's oceans".
