Abstract：In order to establish an objective method for research of body length of mantis shrimp Oratosquilla oratoria at the first maturity and accurately estimate it, a scientific survey of fishery resources was monthly conducted in the Bohai Bay from April to November 2019 (except for May), on the (20th±5th) day of each month by a single vessel bottom net with a width of 10 meters and an inner mesh size of 20 mm. The characteristics of mantis shrimp were measured, and immature and mature female individuals were determined based on the gonado-somatic index (GSI). The relationship between maturity ratio and kubo's standard body length was established to estimate body leng that initial maturity by a modified logistic with a variable asymptote (A). The results showed that the ranges of GSI for wet- and dried-female mantis shrimp were varied from 0.01% to 14.54% and from 0.01% to 24.11%, with the monthly mean of GSI decreases from the peak in April to the minimum in Aug, and then gradually increase during the survey period. The kubo′s standard length at first maturity was found to be (8.33±0.013) cm for wet female samples and (8.63±0.052) cm for dried-female samples. Accordingly, the flag criteria of the reproductive status were from 16% to 28% of the maximum registered wet-GSI and from 8% to 22% of the maximum registered dried-GSI, indicating that robust and stable enough to propose this method be applied to estimate the size of at first maturity and to enrich our knowledge about the relationship between the ratio of maturity and kubo′s standard length for female mantis shrimp. Using GSI to imply the physiological maturity of female mantis shrimp seems more sensible to compare with gonadal development stage. The varied percentages of the maximum obtained GSI of the dried samples present a wide range of the benchmark values to identify engagement into reproduction. The smaller number of individuals identified as reproductive is compensated by a lower asymptote value while increasing the flag values to high values
