我国人工养殖大菱鲆是从上世纪90年代中后期开始的,比欧洲晚大约4-5年。目前,我国大菱鲆的总产量已经超过欧洲养殖总产量,达到15000吨左右,而欧洲的同期产量在6500吨左右。在不到10年的时间里,发展到如此的规模,在我国海水全陆基鱼类养殖史上,可以说是史无前例的。在大菱鲆养殖迅猛发展的同时,市场价格也在发生着巨大变化,从最高峰时的300元/公斤左右,降到今年最低价50元/公斤左右。如此大的价格变化,已使很大一部分养殖者出现亏损。许多养殖者在感到困惑的同时对大菱鲆养殖的前景产生悲观的情绪。以下通过对欧洲几种经济鱼类养殖发展规律的分析,来反思我国大菱鲆养殖的发展历程,希望从中总结经验,使我国的大菱鲆养殖产业能够平稳发展。一、欧洲大菱鲆以及其他经济鱼类养殖发展过程欧洲大菱鲆人工养殖开始于上世纪90年代初,现在主要产地集中在法国、西班牙、葡萄牙、英国及北欧,主要养殖方式是陆基型养殖,全循环水养殖的比例占到75%以上。 Our domestic cultured turbot is from the mid-to-late 1990s, which is about 4-5 years later than in Europe. At present, the total output of turbot in China has surpassed the total output of aquaculture in Europe, reaching about 15,000 tons, while the production of the same period in Europe is about 6,500 tons. In less than 10 years, developing to such a scale can be said to be unprecedented in the history of sea-based land-based fish culture in China. In the rapid development of turbot breeding at the same time, the market price is undergoing tremendous changes, from the peak of 300 yuan / kg, down to this year the lowest price of 50 yuan / kg. Such a big price change has caused a large part of the farmers to suffer a loss. Many growers feel pessimistic about the future of turbot breeding while confused. Following the analysis of the development of several types of economic fish farming in Europe to reflect the development of turbot farming in our country, hoping to sum up experience to make our turbot breeding industry to develop smoothly. First, the European turbot and other economic fish culture development European turbot artificial breeding began in the early 90s of last century, and now the main producing areas are concentrated in France, Spain, Portugal, Britain and northern Europe, the main breeding methods are land-based Aquaculture, the proportion of total circulating water aquaculture accounted for more than 75%.
