Haizhou Bay is a traditional fishing ground in China. Due to overfishing and environmental pollution, large- and medium-sized economic fish resources in this area have declined. Prior research has focused on fish species with high economic value or emerging dominant prey species such as while overlooking non-dominant species such as those in the genus. This group contains numerous small benthic species commonly found in the Haizhou Bay fishing ground, which perform important ecological functions. Fishery resource conservation should be ecosystem-based, so it is necessary to investigate changes in all of the fish resources. Therefore, this study focused on three non-dominant prey species within , to investigate the growth parameters changes under environmental stress. Using data from 18 bottom trawl surveys in the Haizhou Bay from 2011 to 2019, the von Bertalanffy growth function (VBGF) was estimated via electronic length-frequency analysis (ELEFAN) with the TropFishR package in R. The number of samples was relatively small, so bootstrap resampling was employed to improve the robustness of our estimates. The results show that from 2011 to 2019, the three species experienced a population decline and miniaturization. The infinite length of decreased from 21.60 cm to 13.96 cm, while the growth parameter decreased from 19.72 cm to 19.35 cm, and the growth parameter C. richardsoni decreased from 18.74 cm to 14.91cm, and the growth parameter K decreased from 0.45 to 0.43. All three species showed a decreasing trend in infinite length or an declining trend in the growth parameter species as the r-strategists responded to the local environment stressors (e.g., overfishing and environmental pollution). However, shortened infinite body length and increased growth rates manifest one another and may be related to differences in the specific environmental stressors the three species experienced. This study provides important data on the growth and population development of and provides a reference for future assessments and fisheries restoration efforts in Haizhou Bay.
