摘　　要：随着土地和水资源的日益匮乏及环境压力的增加,高效环保的循环水养殖模式逐渐成为趋势。针对循环水养殖中掠食性鱼类在摄食时的水面抢食特征,该研究提出一种循环水养殖波动反馈型投饲装备。该装备以鱼群摄食时水波反馈数据为关键输入参数,投饲机转速为输出参数,实现投饲速度随鱼摄食强度自适应变化。为验证投饲装备的实用性和有效性,以精养珍珠龙胆石斑鱼(Epinephelus fuscoguttatus♀×Epinephelus tukula♂)为对象开展循环水养殖对比试验。结果表明:循环水养殖波动反馈型投饲装备在决策性能方面优于传统投饲模式,纳什效率系数由0.888提升至0.940,控制性能可靠。此外,波动反馈型投饲装备在不影响鱼类生长发育的情况下,饵料系数比传统投饲模式降低11.11%,生长过程中的鱼体分化与差异性变小,养殖效益方面波动反馈投饲模式相比传统投饲模式高了约24.6%。所研制的投饲系统具有较好的综合应用性能,可为其他养殖模式、智能投饲装备研发提供参考和技术支持。An efficient and environmentally friendly recirculating aquaculture system(RAS)has been emerged as the a prominent trend in the aquaculture industry.RAS can also be expected to restore the ever ever-decreasing in the land and water resources,particularly with the escalating environmental pressures.However,the predatory fish can often exhibit the surface surface-feeding frenzy behavior during feeding in RAS.In this study,a wave feedback feeding equipment was introduced for the recirculating aquaculture.This key input parameter was selected as the amplitude of surface waves that generated by the fish fish-feeding activity.The rotation speed of the feeding machine was set as the output parameter.Thereby there were the adaptive changes in the feeding rate,according to the intensity of fish feeding.A comparative experiment was conducted on the RAS setting to validate the practicality and effectiveness of this wave feedback feeding equipment.The test species were taken as the intensively cultured Pearl Dragon-and-Tiger Grouper(Epinephelus fuscoguttatus♀×Epinephelus tukula♂).The fish was reared under two feeding regimes:traditional timed feeding and wave feedback feeding.The experimental results demonstrated that the peak feeding intensity model of the wave feedback feeding equipment outperformed the traditional feeding modes,in terms of the decision-making performance.Specifically,the Nash efficiency was improved from 0.888 to 0.940,indicating the reliable and robust control performance.Furthermore,the wave feedback feeding equipment was significantly reduced the feed conversion ratio(FCR),compared with the traditional feeding modes,with a decrease of 11.11%.Additionally,the coefficient of variation(CV)in the body mass during growth was 15.36%lower than that in the timed feeding group.There was the a decrease in the differentiation and variability among fish during growth.The economic benefits of the wave feedback feeding mode were approximately 24.6%higher than those of traditional feeding.The developed feeding s
