我国养殖对虾的历史不长,从大面积野外试养算起,至今不过十年。这十年所取得的成就却是非常大的,积累的经验也是很丰富的。到1987年止虾池面积已达183万亩,总产量已近××万吨,单产也由几十斤提高到160斤。对虾是我国出口创汇的重要物质,每年出口N万多吨,可以创汇2亿多美元。现在,不仅渔民养,农民养,盐工养,解放军的海、陆、空三军都在养虾,形成了养虾热。从下表中看出,1984年以后的虾池面积增长率均在42%以上,最高达到72%。由于虾池面积和虾产量急剧增长,使很多生态失去平衡,很多措施不能与之适应。目前,人工配合饲料紧张就是一个突
The history of shrimp farming in China is not long, counting from a large area of field nurturing, but only ten years. The achievements made in this decade have been very substantial and the accumulated experience is also very rich. To 1987 shrimp pond area has reached 1.83 million mu, total output has nearly ×× million tons, yield also increased from a few pounds to 160 pounds. Shrimp is an important material for China’s foreign exchange earnings. It exports over 80,000 tons of foreign exchange each year and can earn more than 200 million U.S. dollars. Now, not only fishermen, peasants and salt workers and the armed forces of the PLA, but also the three armed forces of the sea, land and air forces of the People’s Liberation Army are raising shrimp and forming a shrimp-raising heat. As can be seen from the table below, the area of shrimp ponds after 1984 increased by more than 42% and reached a maximum of 72%. Due to the dramatic increase in shrimp pond area and shrimp production, many ecosystems are out of balance and many measures can not be adapted to them. At present, artificial feed tension is a sudden conflict
