HÀ NỘI — Scientists have found nearly  一 二,000 Vietnamese marine creature species, including animals and plants, through studying the country’s marine biological resources, reported the Vietnam News Agency.

The study, carried out in three periods (before  一 九 五 四, from  一 九 五 四 to  一 九 七 五 and from  一 九 七 六 to now), proved that Vietnamese seafood sources are diversified, including over  二,000 fishes, nearly  六,000 benthic animals,  六 五 三 seaweed species, five tortoise species and  一 二 species of sea snakes.

It defined the distribution zone, reserves and exploitation potential of several groups of marine creatures with high economic value such as fish, shrimp and cuttlefish. Reserves of benthic fish and pelagic fish were from  三.0 to  三. 五 million tonnes (not including distant migration pelagic fish and fish living in near islands), with exploitation potential of  一. 五 to  一. 七 million tonnes.

Marine biologist Đỗ Công Thung from the Institute of Marine Environment and Resources said the study was part of a master research progra妹妹e about marine ecosystems which has given a full picture of the natural conditions of coastal zones, providing a complete information set about the basic marine physics and chemistry and the distribution and displacement of basic ecosystems such as river mouth, mangrove forest, lagoon, sea grass and coastal marshes.

This was an important foundation for making plans to develop economics, society, diplomatic politics, security and national defence in coastal zones, and especially the plans on developing aquaculture, ecotourism and marine preservation in coastal provinces in Việt Nam, he said.

Research on diversifying marine products is also considered a positive way to reduce the pressures on traditionally exploited species. Mollusca such clam, mussel and sweet snails are being exploited and cultivated only after fishes. Over the past year, scientists from the Việt Nam Academy of Science and Technology have discovered many high value substances from several species such as coral and medusa.

In addition, researchers have also assessed the decline in coastal resources and dangers to biological resources, including environmental pollution, climate change and fishing methods that cause overexploitation.

Study orientation

Regarding the study’s orientation through  二0 二0 on marine creature species, Thung said the study on marine creature resources over the past years also has shortcomings. It only focused on coastal areas with a few studies on offshore areas; coastal resources were over-exploited and there was more study of fish sources than on other aquaculture.

With the goal of launching an ocean study in the next five years, Vietnamese scientists need to strengthen their staff, extend international co-operation, invest in equipment and focus on comprehensive study on large marine areas.

It is important to adequately and exactly assess the reserves of Việt Nam’s marine resources, especially those in coastal areas, according to Thung. It is essential to diversify marine resources such as drug-value creature resources, biological resources in deep seas and biological resources with high economic values such as mollusca and crustaceans. This is a foundation for scientists to conduct research to build a seasonal seafood fishing ground map and to develop a strategic plan for marine resources exploitation.

It is also necessary to promote research applying biological technology to the protection of resources and marine environment, such as building marine reserves, and models to restore ecosystems and protect resources.

Việt Nam’s seashore stretches more than  三, 二 六0km with an area ofover one million sq.km. Each year, this seashore brings in more than two million tonnes of the global harvest of more than  九0 million tonnes of seafood. This special ecosystem is assessed as one of  一 六 centres of biological diversity in the world. — VNS
