| 摘要: |
| 卵形鲳鲹(Trachinotus ovatus)是当前广西养殖产量最大的海水鱼，养殖产量长期排名全国第二，主要集中于北部湾海域，以深远海网箱养殖模式为主。然而，苗种质量不稳定、养殖风险大、技术门槛高等问题制约了深远海网箱养殖模式的高效发展。卵形鲳鲹“三段式”陆海接力养殖新模式结合卵形鲳鲹陆基育苗和网箱分级养殖等技术，不仅缩短了卵形鲳鲹鱼苗出苗时间，还大幅提高了苗种培育和深远海网箱成鱼养殖的成活率，从而达到节约养殖成本和提高养殖效益的目的。本文总结了卵形鲳鲹“三段式”陆海接力养殖新模式的基本框架、面临的问题及对策，并进行经济效益分析，最后提出应加强绿色养殖技术研发，加快速生高饲料效率良种培育和推进养殖设施升级，为北部湾地区海洋牧场深远海养殖业的进一步发展提供技术支撑。 |

| Abstract: |
| The golden pompano (Trachinotus ovatus) is currently the most extensively cultured marine fish species in Guangxi,with its culture output consistently ranking second nationwide in China.The Beibu Gulf area is the center of T.ovatus farming,where deep-sea cage culture is the predominant culture model.However,the efficient development of deep-sea cage culture is constrained by challenges such as inconsistent seed quality,high farming risks,and significant technical barriers.The “three-phase” onshore-offshore relay aquaculture new model integrates technologies including land-based larval rearing of T.ovatus and size-graded cage culture.This model not only shortens the time required for juvenile production but also substantially improves survival rates during both nursery and grow-out phases in deep-sea cages.Consequently,it achieves reduced production costs and enhanced economic returns.This article summarizes the basic framework,problems,and countermeasures of this model,and analyzes the economic benefits.Finally,measures including strengthening the research and development of eco-friendly culture technology,accelerating the breeding of fast-growing and high feed efficiency varieties,and promoting the upgrading of culture facilities are proposed to provide technical support for the further development of deep-sea aquaculture in the Beibu Gulf area. |
