摘要
论文从卵形鲳鲹的生态习性和养殖、病害防治、市场风险及经济效益等几方面提出深水网箱养殖的风险对策,准确把握市场供求信息。经试验表明,过高的放养密度不利于卵形鲳鲹的生长,并且会增加养殖成本,以40-60尾/m^3的养殖密度为宜,50尾/m^3的利润最好,达170.05元/m^3笔者儿年跟踪海南特定深水网箱养殖合作社统计的数据得出,卵形鲳鲹在投苗规格基本·样的情况下,养成成活率相差不大,其利润率与销售价格正相关。实现卵形鲳鲹环境友好型、高效健康的养殖及提高产品附加值是利润最终提升的根本。
This article from the ecological habits, breeding, and disease control, market risk and economic benefits of the wave-resisted deep-water net-cage breeding of Trachinotus ovatus for risk prevention measures, and get an accurate grasp of market supply and demand information. The results showed that： the high stocking density is not conducive to the growth of Trachinotus ovatus, and will increase the cost of breeding, 40-60 tail each m3 of the stocking density is appropriate, 50 tail each m3 get the best profits, income of 170.05 RMB each m3. We follow the tracks of data statistics from specific cage farming cooperative of Hainan houshui bay, ovate to vote seedlings in the case of essentially the same specifications, Trachinotus ovatus case of the same size fry, and breeding survival rate of less the same. Profit margin was positively correlated with the sales price. Environmentally friendly, efficient and healthy way to breeding Trachinotus ovatus, and increase its value-added products, these are ultimately enhance profits for all.
