摘　　要：研究了珍珠龙胆石斑鱼(Epinephe lusfuscoguttatus♀×E.luslanceolatus♂)与3种不同海水植物工厂化原位混养系统的动植物生长及水质变化情况。实验设4个处理组,分别为珍珠龙胆与菊花江蓠(Gracilaria lichevoides)混养(FA),珍珠龙胆与长茎葡萄蕨藻混养(Caulerpa lentillifera)(FB),珍珠龙胆与海马齿(Sesuvium portulacastrum)混养(FC),以及珍珠龙胆单养(F)。结果表明,石斑鱼的特定生长率在0.69~0.82%之间,以实验组FC最高,显著高于FA和对照(P<0.05),而与FB差异不显著(P>0.05);饲料系数在1.02~1.11之间,以FC最高,显著高于FA和对照(P<0.05),而与FB之间没有显著差异(P>0.05)。三种混养植物的净产量方面,以海马齿最高,达(1730.26±117.01)g·m^(-2),显著高于菊花江蓠和长茎葡萄蕨藻(P<0.05)。各混养处理的水质指标整体上均优于石斑鱼单养,其中以处理FC的整体水质条件最好,其PO_4^--P、COD、悬浮物浓度等指标均显著低于其他处理组(P<0.05)。研究表明,工厂化养殖模式下珍珠龙胆石斑鱼与菊花江蓠、长茎葡萄蕨藻、海马齿3种海水植物原位混养的养殖效果均优于石斑鱼单养,其中以珍珠龙胆与海马齿的混养效果最佳。The growth of plants and animals and water quality of industrial in situ integrated aquaculturesystems of Epinephe lusfuscoguttatus (♀)×E.luslanceolatus (♂)with different sea water plantswere researched.Four treatments were set in the experiment,i.e.,grouper polyculture with Gracilarialichevoides (FA),grouper polyculture with Caulerpalentillifera (FB),grouper polyculture withSesuviumportulacastrum (FC),and grouper monoculture(F).The results showed that the SGR ofgrouper ranged from 0.69% to 0.82%,and the highest SGR appeared in FC,which was significantlyhigher than that in FA and F(P<0.05);the feed coefficient ranged from 1.02 to 1.11,and the highestfeed coefficient appeared in FC,which was significantly higher than that in FA and F(P<0.05).Thenet yield of Sesuvium portulacastrum was 1730.26±117.01g·m^-2,and was significantly higher thanthat of Gracilaria lichevoides and Caulerpa lentillifera Gracilaria (P<0.05).As a whole,the waterquality index in each polyculture treatment was superior to that in the grouper monoculture,and thewater quality condition in FC was best overall,the PO-4 -P,COD,suspended solids concentration inFC were significantly lower than those in other treatments(P> 0.05).In summary,the culturingeffects of industrial in situ integrated aquaculture of Epinephelusfuscoguttatus (♀)×E.luslanceolatus(♂)with each sea water plants above were superior to those in grouper monoculture,and Sesuviumportulacastrum was better than other two plants for polyculture.
