摘要
为探究一种海水生态混养模式,以碱蓬(Suaeda glauca Bunge)、黑鲷(Sparus macrophslus)和菲律宾蛤仔(Ruditapes philippinarum)为养殖对象,通过设置碱蓬-菲律宾蛤仔、碱蓬-黑鲷、碱蓬-黑鲷-菲律宾蛤仔、黑鲷-菲律宾蛤仔4种混养模式(黑鲷鱼苗养殖密度为155尾/m3、菲律宾蛤仔养殖密度为75 ind./m^(2)),在养殖过程中监测各体系水质指标以及养殖对象生长指标。结果表明,碱蓬-黑鲷体系、碱蓬-菲律宾蛤仔养殖体系具有较强的水体自净能力,水体氨氮、总磷、亚硝酸盐氮含量在养殖后期均呈现下降趋势,两种体系呈现较好的稳定性,而菲律宾蛤仔与黑鲷混养的两种体系水质指标较差,养殖对象死亡率高,系统缺乏稳定性。在黑鲷鱼苗155尾/m^(3)、菲律宾蛤仔75 ind./m^(2)密度条件下适宜建立碱蓬-黑鲷或碱蓬-菲律宾蛤仔混养模式,体系中碱蓬不仅可以净化水质,而且可以增加养殖水体溶解氧含量、稳定养殖水体pH。
In order to explore a seawater ecological polyculture model,three culture objects of Seepweed(Suaeda glauca Bunge),black sea bream(Sparus macrophslus)and Philippine clam(Ruditapes philippinarum)were selected.By setting up seepweed-philip⁃pine clam,seepweed-black sea bream,seepweed-black sea bream-philippine clam and black sea bream-Philippine clam four types of polyculture models(black sea bream fry breeding density is 155 fish/m^(3),Philippine sea clam culture density is 75 ind./m^(2))with the water quality ind.icators and cultivation of each system monitoring during the breeding process,we try to explore the characteristics of each model.The results showed that the seepweed-black sea bream system and the Seepweed-Philippine clam system have strong wa⁃ter self-purification ability.The ammonia nitrogen,phosphate,and nitrite nitrogen contents of the water body all show a downward trend in the later stage of the experiment,and the two systems show better results.However,the water quality ind.ex of the two systems of Philippine clam and black sea bream polyculture was poor,the mortality of the breeding subjects was high and the system lacks sta⁃bility.The black sea bream of 155 fish/m^(3) and Philippine curtain clams of 75 ind./m^(2) density were suitable for the establishment of Seepweed-black sea bream or Seepweed-Philippine clam polyculture model.Seepweed in the system can not only play a role in purify⁃ing water,but also increase the dissolved oxygen content of aquaculture water,and stabilize the pH of aquaculture water.
