深水网箱养殖现状
摘要：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、流动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。我国在深水网箱养殖方面起步较晚，但因其高效益、高性能近年在全国沿海省市引发了国产化研制的热潮。随着深水网箱业的快速发展,带来的问题也逐渐显现,养殖系统一次性投资较大,产业配套不完善,包括深水网箱的配套设施、养殖技术与主养品种、养殖布局与养殖容量、饲料与病害防治、产品加工与流通等,直接制约了深水网箱的发展,结果是导致深水网箱养殖设施空置率偏高。解决深水网箱养殖产业化发展存在的问题,首先实施深水网箱高技术集成,完成养殖产业链(群)的连接,建立全新养殖模式,与渔业产业结构性调整的政策性衔接,是深水网箱产业化的重要研究课题。所以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。
