中文摘要:
      报道了中华绒螯蟹育苗用水调配原则与不同基础水调配方法的研究结果。育苗用水调配的基本原则是Mg2+与Ca2+含量及Mg2+/Ca2+比值(R)必须达到一定的范围。以鱼塘水与深井水作基础水时,需分别添加6种与10种化学药品,其中Mg2+与Ca2+含量及R值可适范围均分别为484~816mg/L与178~340mg/L,R值均为2.0~3.0。研究表明,以河口水育苗最为经济,如盐度或Mg2+与Ca2+含量及R值不在可适范围内,则可淡水稀释或添加浓缩海水,并将Mg2+与Ca2+含量及R值调配到合适范围。
英文摘要:
      Mixed principles and me thods with differen t basic water for re ar ing larva of Chinese mit ten cr ab (Eriocheir sinensis)were studied from 1995 to 1996 on the Ping Hu Fisheries Test Farm of Zhej iang Pr ovince .The results were as fol lows : Using freshwater as the basic water in the fish pond for rear ing lar va , six chemical reagents(MgSO4 ,CaCl2 ,KCl , FeCl3 ,H3BO3 , NaCl)must be added to the basic water .Using deep-well water as the basic water the above 6 chemical reagents and KBr , KI ,Na2H2PO4 , CuSO4 must be added to the basic water .The suitable contents of Mg2+ and Ca2 in both the mixed water wer e 484 ~ 816mg/L and 178 ~ 340mg/ L r espect ively at Mg2 /Ca2 (R)of 2 .0 ~ 3 .0 .The study showed rear ing larva with alongshor e estuar y water was the most economical way .I f the contents of Mg2 ,Ca2 or R were not in the above suitable r anges , the basic water could be diluted with freshwater , or concentr ated se awa ter could be added to the basic wate r , then the contents of Mg2 , Ca2 or R could be mixed to the above suitable ranges .
