摘要： To evaluate the biomass distribution of fishery resources for hydroacoustic data, acoustic measurement was combined with ordinary kriging (OK) to perform data processing, which was supported with trawling data. Acoustic data were collected during daytime by using a Simrad EY60 echosounder with 70- and 120-kHz split beam transducers. Afterward, the undesirable data were eliminated, data transformation was carried out, the semivariogram models were statistically compared and filtered and subsequently OK was performed. The goodness of fit of OK was also assessed with the determination coefficient (R2), mean error (ME), and root mean square error (RMSE). The exponential model was the most suitable semivariogram model for the data, and the goodness of fit of OK was good (R2 = 0.8986, Pearson's r = 0.9481). The distribution pattern of fishery resources is probably less distributed from north to south and from east to west, which is consistent with the findings in the Summer between 1998 and 1999.
