基于硬壳蛤的大菱鲆养殖尾水资源化利用研究
Resource utilization of tailwater in the cultivation of the Scophthalmus maximus based on Mercenaria mercenaria
摘要
Abstract
Scophthalmus maximus is a commercially significant species in industrial mariculture in northern China.The high degree of intensification and high volume of water displacement make the tailwater rich in nitrogen and phosphorus nutrients,which leads to the waste of resources and increases the difficulty of management.This study quantified the contents of chemical oxygen demand,nitrite,nitrate,ammonia nitrogen,active phosphate,total phosphorus,total nitrogen and total suspended solids present in the tailwater of S.maximus aquaculture.The eu-trophication potential scale was used to evaluate the level of water eutrophication,and the single-factor pollution index method was used to analyze the main pollution characteristics.The experiment compared the growth of Mer-cenaria mercenaria in the tailwater of S.maximus and a shellfish pond.The findings revealed that the excessive primary components in S.maximus aquaculture tailwater were inorganic nitrogen and active phosphate,resulting in a high level of eutrophication.The high levels of nitrogen and phosphorus in the tailwater can create ideal nutrition conditions for the growth of monocytic algae and provide sufficient food for the growth of M.mercenaria,thus achieving maximum utilization of the resources in the S.maximus tailwater.关键词
