摘要
利用地热水进行罗氏沼虾越冬试验。定时充气增氧,每天排污,日换水量15%～25%。约20d大换水一次,彻底排污。投喂人工配饵,消毒防病。实验证明:越冬水温21～25℃,溶氧保持3mg/L以上,能加速越冬对虾生长和发育,促进交尾,提高成活率。
Over-wintering of Macrobrachium rosenbergii was carried out in geothermal water with aeration, and daily water exchange of 15%～25%. High copulation and survival were found at water temperature 21～25℃ and dissolved oxygen level of above 3 mg/L.
