ASSESSMENT CONCLUSIONS m A I ENVIRONMENT IMPACT ASSESSMENT REPORT ON THE PROJECT OF SUSTAINABLE DEVELOPMENT OF CHINESE COASTAL RESOURCE Introduction Since the reformation and open door policy were carried into effect, Chinese fishery has been rapidly developed. The rise ratio of aquatic-production is 13.6% annually, which is much higher than the world average level of 1.5%. The total yield in 1995 reached 28000 metric ton which accounted for 25% of the total yield of the world and ranked first in the world. Chinese fisheries is taking a fishery developing road with Chinese characteristics. In the procession of fishery development in China, some new problems emerged, among which diseases of culturaled species (for example, prawn disease)occurred serious in recent years, natural resources of marine fishery seriously declined, water quality of coastal areas nearby big cities and industrial zones became polluted, and over-exploiting of fisheries in some areas have exceeded their bearing capacity. The problems mentioned above directly influence whether the Chinese fishery can be sustainable development. The Chinese relevant authorities have recognized this serious problem and made their best endeavours to solve it. However, the fishery is a trade with high investment and high benefit. The funds for developing fishery must be raised through various channels. One of the channels is to introduce foreign funds for expediting the development of Chinese fishery. For this reason, the Ministry of Agriculture in China has applied for a World Bank loan for the project of comprehensive development of fisheries in the southeast coastal area of China in 1995. The State Planning Committee in China has arranged the project for the three years' rolling plan of World Bank loan. The project group of World Bank visited China and investigated the project in May of 1996. After consulting with the State Planning Committee, the Ministry of Finance , the Ministry of Agriculture and the relevant departments of the project areas, the project was finalized and named as "the project of sustainable development of chinese coastal resources The total amount of the loan is 100 millions $US. Because the project of sustainable development of Chinese coastal resources is a constructing project of ecological agriculture , the object of construction is to ensure marine ecological balance and reaches sustainable and good e'cological circulation of fisheries. Therefore, the scope and degree of disadvantageous impact caused by environment will be limited and some disadvantageous impacts in the process of construction and production may be reduced to an acceptable degree by adopting advanced technology and proper measures of prevention and control. Brief Description of the Project Fujiang, Jiangsu (Nantong city), Shangdong and Liaoning provinces are designated as the project areas. The project involves 4 parts, namely the management of coastal zones, sustainable aquatic culture and mariculture, reconstruction of prawn ponds, and quality and safety of aquatic production. * Managementof Coastal Zones The management plan of coastal zones will include the following items: 4 Three management centers of coastal zones; 4 Four fishery environmental monitoring stations; 4 One center of prevention and control of disease and technical training; - Five stations of prevention and control of disease and technical training; 4 One protected zone of precious and rare aquatic animal; 4 Nine fishery administrative boats; 4 One monitoring and controlling system of fishing boats; 4 6000 hectares coastal preventing and protecting Inter Tide Zone culture; 4 Three training teams of coastal management; * Sustainable Aquatic Culture and Mariculture 4 Fish culture The plan of fish culture is listed in Table 1.
