1、不同鱼卵的孵化方法Hatching methods of different fish eggs一、常见鱼卵的类型 common types of fish eggsv1、浮性卵 floating eggs卵的比重小于水，漂浮于水面或悬浮于水层中漂浮于水面或悬浮于水层中，大多无色透明。gravity of eggs is less than water, so eggs can float on the surface of water or suspend in water. Most of them appear colorless and transparent.vv大多数海水鱼类属此，
2、有少数淡水鱼类大多数海水鱼类属此，有少数淡水鱼类如鳜鱼卵。most of marine fish eggs and most of marine fish eggs and few kinds of freshwater fish eggs, few kinds of freshwater fish eggs, such as mandarin fish eggs, such as mandarin fish eggs, belong to floating eggs. belong to floating eggs. vv2 2、粘性卵：卵重于水，卵膜有粘性，附着在水草、粘性卵：卵重于水，卵
