| 摘 要： | 鱼类栖息水中随着时间的增加，排泄物不断增多，特别是鱼类密集成群时，排泄物显著增加，从而影响到水质的变化；在较浅的水域里，往往凭感官即能察觉出来。例如有经验的渔民认为冬季带鱼汛期，渔场海水常有一种特殊的“香味”，并以嗅此种“香味”作为寻找鱼群的指标。

| Abstract: | The authors have made a coast-wise investigation of the fishing ground of Kiangsu from1960 to 1963, and have found out that there is a relation between the variation of fish sch-ool and ammonia content in water. It is shown that the greater the density of fish schoolis, the larger the excretion becomes, and the more the ammonia content in water increases.Results of the investigation on Pseudosciaena polyaotis (Bleeker) , Pseudosciaena orocea(Richardson), Trichiurus haumela (Forskal), Setipinna taty (Cuvier Valenciennea) and Ilisha elongata (Bennett) show that, in the water level or vertical column of water, the am-monia contents are all very high, where the fish schools are crowdy. |
