He said certain species of fish face extinction if overfishing and pollution go unchecked. Overfishing has resulted in depleted populations in the Bohai Sea and other coastal waters.
The hair tails one of China's four favourite ocean delicacies (the other three being the great croaker, lesser croaker and ink fish), are degenerating year by year. The total output declined to only 100,000 tons last year from about 600,000 tons a few years ago. Their weight has also dropped to around 100 grams from 500 grams.
And the prawn, one of the most vendible shrimps on the world market, is also facing the threat of extinction caused by the overharvesting in Bohai Sea.
The rules, regulations and various controls on fishing that have been issued in recent years have yielded little effect because of repeated violations by fishermen and regional protectionism.
To protect prawn resources, .a joint investigatory and supervisory fleet(has begun patrolling seaports, river mouths, waterways and coastal areas in Liaoning, Hebei and Shandong provinces and in Tianjin.
The patrol aims to stop the harvesting of immature shrimp and illegal trawling. It is empowered to confiscate vessels without licenses and foreign boats violating territorial fishing boundaries.
But the coastal patrols, which have been strengthened year by year, are not very effective because of the vast sea area and its limited personnel and equipment.
