罗非鱼原产非州,属热带鱼类,喜温怕寒,对低温的抵抗能力很差,长期处在12℃以下,就会冻死。因此,确保罗非鱼安全越冬,一般都要利用工厂的余热或温泉,在广西玉林地区对于利用水库解决罗非鱼的越冬和繁殖问题,是水库渔业工作的一道新课题。1983年,博白县的六确、充粟水库的渔业职工,在水库环境条件差,养殖经验缺乏的情况下,对这个问题进行了新的偿试。11 Tilapia origin of non-states, is a tropical fish, hi temperature and cold, low temperature resistance is poor, long-term at 12 ℃ below, it will freeze to death. Therefore, to ensure the safety of winter tilapia, the general use of factory waste heat or hot springs, the use of reservoirs to solve the overwintering and breeding of tilapia in Guangxi Yulin area is a new issue of reservoir fisheries. In 1983, the fishing workers in Liuzhou and Sunsu reservoirs in Bobai County carried out new tests on this issue under the conditions of poor reservoir environment and lack of breeding experience. 11
