Article Abstract

We investigated microplastics (MPs) pollution in 349 Larimichthys polyactis specimens from the coastal area of Jiangsu Province, China. The MP abundance in L. polyactis was 1.03 ± 1.04 items/individual and 0.95 ± 0.92 items/10 g (wet weight). The MP abundance in specimens from the Haizhou Bay fishing ground was slightly higher than that in specimens from the Lvsi fishing ground. Spearman's correlation showed that MP abundance was positively correlated with body length when expressed as items/individual, but not items/10 g. The abundance in the gastrointestinal tract was slightly higher than that in the gills, but the differences were not significant for either measurement index. The MPs predominantly ingested by L. polyactis were <1 mm, fibrous, blue and had a cellophane composition. The MP pollution in L. polyactis in the coast of Jiangsu Province is at a medium to low level, as compared with other regions of China.

In recent decades, China's large-scale stock enhancement programs to restore the collapsing large yellow croaker () fishery resources have not yielded the desired results, and a comprehensive analysis of the underlying reasons for this problem is required. Based on small yellow croaker () catch survey data obtained from 15 fishing ports along the coast of the East China Sea, we examined the proportion of large yellow croakers mixed in the small yellow croaker catch and their biological parameters. In addition, we analyzed the differences in the intestinal microbiota and feeding ecology between these two species to explore the reason why the stock enhancement program failed to achieve the desired outcome.

To understand the habitat distribution characteristics of in summer in Jiangsu coastal waters, we analyzed the relationship between resource density and habitat environment of by using a two-stage generalized additive model based on the survey data of fishery resources in August 2022, combined with the data of bottom water temperature, bottom salinity, depth, chlorophyll-a and prey species. The results showed that the average resource density of in summer was 15.03 kg·km, which mainly distributed in the outer sea area of Lusi Fishing Ground and the middle sea area of Haizhou Bay Fishing Ground.

The problem of marine noise pollution has a long history. Strong noise (>120 dB re 1 µPa) will affects the growth, development, physiological responses, and behaviors of fish, and also can induce the stress response, posing a mortal threat. Although many studies have reported that underwater noise may affect the survival of fish by disturbing their nervous system and endocrine system, the underlying causes of death due to noise stimulation remain unknown.

Hypoxic stress can result in redox imbalance and apoptosis in teleostean fishes; however, the precise molecular mechanisms underlying this process, including its regulation by the key signaling pathway Kelch-like ECH-associated protein 1 (Keap1)-nuclear factor erythroid 2 related factor (Nrf2)/antioxidant response element (ARE), remain elusive. Therefore, in this study, we chose the Keap1-Nrf2/ARE signaling pathway as the entry point and a combination of in vivo (target organ liver) and in vitro (small yellow croaker fry [SYCF] cell line) experiments to investigate the molecular mechanism by which Larimichthys polyactis (L. polyactis) adapts to hypoxic stress by regulating redox balance and apoptosis.
