Abstract: Fishery resources in the Bohai Sea have declined markedly due to overfishing and habitat degradation, leading to an
increasing dominance of invertebrate species such as the mantis shrimp Oratosquilla oratoria. Here, we estimated growth para-
meters of O. oratoria using ELEFAN GA method with Bootstrap resampling based on length–frequency data collected in 2014,
2015 and 2024, and conducted a management strategy evaluation (MSE) while propagating uncertainty through alternative nat-
ural mortality coefficient (M) estimates. The results indicated that the length-weight relationship in 2014 and 2015 was W=
2.94
0.014 8·L and estimated growth parameters were asymptotic body length (L inf ) of 20.14 cm and growth coefficient (K) of
2.78
0.74, respectively. In 2024, the length-weight relationship was W=0.022 8·L , and L inf and K were 20.19 cm and 0.73, respect-
ively. A total of 16 management practices (MPs) were identified as feasible MPs for the management of O. oratoria in the
Bohai Sea, including 9 input controls and 7 output controls. Across all M-setting scenarios, input controls generally performed
better than output controls in maintaining stock status and yield and avoiding overfishing performance metrics. Moreover, only
curE80 (80% of current effort level) consistently provided the best overall trade-off between conservation and exploitation
among all M scenarios. Our results therefore recommend curE80 as a priority MP for O. oratoria in the Bohai Sea, while
emphasizing that management outcomes remain sensitive to M estimates.
