深水网箱养鱼业的现状与发展趋势

深水网箱是指设置在相对较深海域，养殖容量较大，具有较强的抗风浪、流性能的海上养殖设施。它在拓展养殖海域、减轻沿岸环境压力、提高养殖鱼的质量、增加养殖效益等方面已显示出明显的优势。由于它是新兴的一种设施渔业，能包容的高新技术多，涉及材料、机械、电子、苗种、饲料、环境等诸多方面，当前仍有不少技术问题需要解决。建议今后对此产业加强宏观管理和指导，改进设施，改善管理，加强科技投入，提高业者素质，扩大经营规模，提高产品质量，借鉴世界上渔业发达国家的经验，使这一产业健康、持续发展。

Current situation and development tendency of deep sea cage fish culture

Deep sea cage is generally referred to as marine culture facilities which is set at a relatively deep water area and has a relatively large culture capacity and stronger anti wave, flow and wind abilities. Ever since it was developed, it has the advantages over others in such aspects as widening culture areas, releasing inshore culture stress on environment, improving fish quality and increasing culture benefits etc. It is a new brand facility fishery, which incorporates much high technology and also relates to many disciplines, like material, machinery, electronics, fish species, feed and marine environment and so on. For the time being, there are several problems to be overcome. It is recommended that the industry should be macro controlled and guided, facility improved, management improved, sci tech input increased, culturist educated and trained, and culture scale widened, and above all, the industry should learn strong points from fishery developed countries in the world as a whole in order to make itself develop healthily and sustainably.
