    摘要:

    渔业资源评估一般有两种数据来源,即科学调查数据和渔业生产数据;前者需要定期出海采样,耗时长且费用高,后者易于获取但样本代表性存在问题。本研究以山东近海口虾蛄为例,基于电子体长频率方法(ELEFAN)评估了口虾蛄的生长参数,采用bootstrap重抽样方法比较了基于渔业生产数据与科学调查数据分析结果的差异,旨在探讨渔业生产数据在估算生长参数上的准确性。结果表明,科学调查数据估算得到的口虾蛄von Bertalanffy季节性生长方程中的极限体长=171.70 mm,和"夏季点"t的估算与科学调查数据估算的结果较为接近,但对极限体长的估算误差较大。因此口虾蛄生长研究需要依靠科学调查数据的支持,同时渔业生产数据可以作为辅助信息。

    Abstract:

    There are generally two sources of data for fisheries stock assessment:fishery-dependent and -independent data. The former involves data collected on commercial fishing vessels by fisheryman, while the latter requires routine surveys by researchers that are time-consuming and expensive. Fishery-dependent data is easier to obtain, but there may be problems with regard to its representativeness. This study used (a species of mantis shrimp found in the Western Pacific) as an example to compare the performance of fishery-dependent and -independent data in the parameter estimation of the von Bertalanffy growth equation. With the decline of fishery resources in recent years, has become an important fishery species in China's coastal areas. At present, the research on the biology of is not systematic and this restricts the scientific evaluation and management of fishery resources. Bootstrap re-sampling was used to establish the same sample size. Both types of data were collected from the coast of Shandong province using a 220 kW single-trawling vessel with a bottom trawl of 1380 mesh×4.67 cm (height 7.53 m and width 15 m when deployed). The growth parameters were estimated using a length-frequency method, Electronic Length Frequency Analysis (ELEFAN). Our results showed that the asymptotic body length () estimated using fishery-independent data were 193.27 mm and 0.62, respectively, whereas the estimated by fish-ery-dependent data were 171.63 mm and 0.66, respectively. Nonparametric tests indicated that the three parame ters, s) of were significantly different between the estimates obtained from the two sampling methods. The results suggest that fishery-dependent data may reflect the growth pattern to a certain extent, i.e., the estimates of are close to the results obtained using fishery-independent data, but there is a large error in estimating . Therefore, the estimation of growth characteristics should rely on fishery-independent data for , whereas fishery-dependent data can be used as auxiliary information.
