摘要
１９９５年１１月至１９９６年５月，进行了较大规模的池塘鲈种自然越冬生产性试验。本文仅报告－口０．１３ｈｍ２微咸水池塘越冬技术及效果：投放鲈种３０００尾，越冬后出池２１４０尾，越冬成活率７１．３３％，平均全长和体重分别增加２．９ｃｍ和２９．７ｇ。对池塘自然越冬与塑料大棚保温越冬进行了经济效益比较。
From Nov. 1995 to May. 1996, an experiment was conducted on natural overwin- tering of perch fingerlings. The paper only reported the result of the experimental overwintering in 0 . 13 hm2 pond with slightly running water. 3000 perch fingerlings were stocked into the winter- ing pond and 2140 perch fingerlings came off the pond . The survival rate was 71 . 33% . The body length and weight of the perch after overwintering increased respectively 2 . 9 cm and 29 . 7 g on average .
