一、苗种在鱼类养殖业中的地位我区水面资源比较丰富。黄河贯穿境内400余公里,两岸有平坦的引黄灌区,沟渠纵横,湖沼、池塘成群,加上兴修的水库和地震形成的水堰,总水面达到120万亩,其中可用于养殖鱼类的水面约占10％。库堰有大量畜粪随雨水流入,水质较肥,湖沼、池塘水草丛生,鱼类饵料比较丰富,发展鱼类养殖业的条件比较好。但是,由于受气候、水质等因素的限制,鱼类养殖发展缓慢,养鱼水面不足4万
First, the status of seed in the fish farming I area is rich in water resources. The Yellow River runs through more than 400 kilometers of the territory. Both sides of the Yellow River have a smooth irrigation area, ditches, lakes and ponds and swarms. Together with the reservoirs to be built and the weir formed by the earthquake, the total surface of water reaches 120 million mu, of which the fish can be used for farmed fish Water surface accounts for about 10%. There is a large amount of stock manure dams with the inflow of rainwater, water quality is more fat, lakes, ponds and grass, fish food rich, the conditions for the development of fish farming is better. However, due to the climate and water quality constraints, the slow development of fish culture, aquaculture water surface less than 40,000
