| 肥满度与含脂量是含义不同的两个生物学指标。二者的季节变化不尽相同，它们表示的肥满和消瘦的季节也不相同。肥满度不能替代含脂量。含脂量的研究对于渔业的合理利用是重要的，应予重视。 |

| ON FISHERY APPLYCATION OF FAT CONTENT AND CONDITION FACTOR OFFISHES |
|
|
| Abstract: |
| There are similar tendencies of seasonal variation between the fat content and the condition factor of large yellow croker, Pseudosciaena crocea (Rich.), from January to June, i. e. both of them decrease monthly. However, from July to December different tendency occurred that the condition factor rises above the mean of year rapidly and the fat content falls below the mean. The fat content in the muscle of large yellow croker is the highest in winter and the lowest in summer (spring spawners) and in November (autumn spawners); the condition iactor is the highest in autumn and the lowest in June. It is obvious that there are dissimilarites in fat and meager seasons as shown by the fat content and the condition factor of large yellow croker. It will be seen from this that the fat content and the condition factor are two different biological indices, which should not be lumped together. Attention should be paid to fat content for rational use of resources in fishery research. |
