This paper dealt with the relation between the fishing effect and soaking time of cuttlefish gillnet.
The results were as follows:
1) The catch of one unit gear (one tan), as soaking time of gear increased, generally changed in 3 steps, this is, increase, decrease and notable increase. But the trend of step varied with fishing ground and/or fishing season.
2) Within the soaking time, 300-1100 minutes, the correlation coefficient between CPUE and soaking time indicated a negative figure, the fishing efficiency decreaced as soaking time of grar increased. Regression coefficient varied with fishing ground and/or fishing season.
