Speaking of doing rescue from marine fishery resources
About 71% of the earth's surface ocean is rich in fish and other aquatic animals. 70 years before the last century, the world's marine fish catch of about 6% annual rate of growth, but in the early 70s, due to sharp decline in catches in Peru makes growth rate decreased. Between 1980 to 1989 the total growth rate of only 23%, occurred in 1990, the first cut since 1976, a decrease of 3%. This trend led to the recognition was considered to be "inexhaustible" in development and utilization of fisheries resources has reached the limit, the world's major economies have been over-exploited fisheries resources or have a recession. With the population growth and social development, people will further increase the demand for aquatic products. Global face of population growth, resource decline and environmental degradation on three major issues, therefore, the sustainable use of fishery resources has become the world's fishing industry is an important research topic.
Experts Call for other deep-sea fish to fishing light
In recent years, Canadian researchers have studied North Atlantic seabed fish, of fishing boats over the past few decades, the fishing log and found that there are at least 5 species of fish in 1978 to 1994 a decrease of 89% to 98%. This means that the tail sturgeon, blue sturgeon, spiny eel deep-sea fish such as 5 A little carelessness can be stripped bare of commercial fishing vessels fishing. In addition, the fishing industry so that the longer the small deep-sea fish. Fishing to deep sea fish frequently not enough time to grow up to be fishing, so in ten years, these 5 have four kinds of fish are reduced, the body 25% smaller to 57%.
In this regard, the study led by doctoral student Jennifer Memorial University of Newfoundland? Diwan said, "Although people do not value these fish, but they have an important role in the ecosystem." Therefore, "If we do not take action, our likely will become a barren ocean. "
In order to improve this critical situation, the scientists came up with various methods. Niuyue Lan Memorial University, Dr. Meyers said: "We now have to master a technology that can put the fish back to 2000 meters deep in water." But said that such methods are not feasible, because even if no fish were arrested after up fatal injury, will also be net crushed. And fishing industry in Alaska is known for came up with an alternative, they use new technology to "reverse" of fish acoustic, fishing for fish to bypass points.
Out together to do from say, efforts to protect fisheries resources
At last year's international conference on high seas fisheries management, the theme was identified as "from the said do", urged the international community to increase efforts to stop the high seas overfishing, protection of fisheries resources. Also focused on how to implement the 1995 United Nations fisheries agreement to develop the relevant provisions and measures; identify impede the implementation of existing regulations to stop overfishing causes of regions in the implementation of these international regulations concerning the differences; study to stop overfishing The special measures taken, etc..
Canadian Prime Minister Paul Martin called the meeting, States should take action and adopt more effective measures to protect the high seas fishery resources and also should better protect the world's fisheries resources and strengthen cooperation.
In fact, the current development trend of international fisheries management is to this direction, and have achieved certain results, such as the "United Nations Convention on Law of the Sea," "on the Conservation and Management of Straddling Fish Stocks and Highly Migratory Fish Stocks in the provisions of "" cod fishery resources in the Bering Sea Convention "and other internationally or signed and regional legal provisions into effect. All the countries in the pursuit of common interests on the basis of sincere cooperation, to ensure that a number of regional sustainable development of fishery resources. However, in practice, the cooperation between the countries there is still considerable difficulty. Mainly due to the level of economic development between countries, resource values, resource use, way of life and so there are some differences.
Therefore, the U.S. oceanographer K? Sherman and marine geologists L? Alexander proposed the concept of large marine ecosystems, it makes the management of fisheries resources management from a variety of resources to the overall system level development so that the management of fishery resources from the narrow administrative division management to ecology and geography to the border-based ecosystem management. Oceanic ecosystems of the main contents include dynamic monitoring of the implementation of fishery resources, analysis of impact of changes in fishery resources, the dominant factor in the marine area, features, functions and structure of the research, which will help to protect fisheries resources, management and sustainable use of .
Should Qiou Union strategy for a durable use of natural resources
The European Commission recently proposed a program aimed at reducing energy consumption, sustainable use of natural resources development strategy, and called for the world to be a positive response.
European Commission press release said that with the increase in economic activity, human use of natural resources is increasing, unreasonable use of over-exploitation of land, water, fossil fuels, and fishery resources will result in global warming, ecological balance and energy depletion and other serious problems. The European Commission put forward the sustainable use of natural resources development strategy, the purpose is to ensure that rapid growth in economic circumstances, to avoid over-exploitation of natural resources continues.
Based on this strategy the European Commission proposed the following measures: the establishment of a European Commission responsible for the data center, collecting and EU policy makers to provide all the information on natural resources and their protection; cooperation with UNEP to establish an international working group , collected the world's scientists on the rational use of natural resources, research results and recommendations; EU member states in the European Commission and other agencies under the coordination of resources to develop their own protective measures.
At the same time, this strategy also identified three objectives: first, by improving the technology to fully enhance the added value of natural resources, namely the use of fewer resources to create higher value; the second is to improve the economic efficiency of resources, minimize environmental pollution caused by the use of resources; third is the development of small polluting new energy, reducing the use of natural resources on the serious environmental damage.
