“…Our results also provided support for the pollution resistance hypothesis, showing that invasive species reacted to the toxicity of PE and TWPs with less pronounced changes in behaviour triggered by PE and TWPs compared to native species. Bold individuals of zebrafish were found to have a higher exposure burden to MPs than shy individuals, which is contrary to the common perception of better survival chances among bolder individuals (Chen et al, 2022). The pollution resistance hypothesis is likely valid only in selected scenarios.…”

“…A behavior analysis software EthoVision XT 15.0 (Noldus, Wageningen, The Netherlands) was used to automatically analyze fish motion data and to derive activity trajectory heat maps of the experimental fish. For the personality test, the boldness of the fish was quantified by using ImageJ2 (University of Waikato, Hamilton, New Zealand) to calculate the area (cm 2 ) of the activity trajectory of the experimental fish ( Table 1 ) [ 40 ]. The latency time was used to analyze the exploratory desire and ability.…”

Personality, which matters for animal welfare, demonstrates behavioral differences. Light is one of the most important factors in aquaculture. However, how fish personality affects light color selection is unclear. In this study, we tested the personality of yellow catfish Pelteobagrus fulvidraco juveniles and then quantified the selective behaviors of different personalities under six light colors: violet (410–420 nm), yellow (580–590 nm), green (550–560 nm), red (620–630 nm), blue (470–480 nm), and white. The results showed that juveniles preferred the yellow and green light over the other colors of light, probably due to different reasons. The average cumulative dwell time in yellow (32.81 ± 5.22%), green (21.81 ± 3.58%), and red (26.36 ± 4.89%) lights was significantly longer than the other light colors, and the average visit frequency in green light (32.00 ± 4.93%) was the most. Juveniles had the longest total moved distance in green light. Moreover, the results demonstrated that shy and bold individuals had the same preference for the green light. Bold individuals could find the preferred light colors rapidly and make quick decisions for light color selection. After identifying the preferred light colors, bold individuals reduced the frequency of exploration. This study provides a theoretical basis for the welfare of juvenile yellow catfish in aquaculture.

“…However, some MPs with smaller particle sizes dissociate from the adsorbed HMs and enter the circulatory system of fish and may result in dual toxic effects from MPs and HMs. First, MPs cannot be digested and absorbed in fish, and they often lead to lumen obstruction, scratches, and a series of problems, such as asphyxia, digestive tract obstruction, and mechanical organ damage [ 18 , 19 , 20 ]. On the other hand, chronic injury accompanied by biological life history changes can lead to alterations in appetite, decreases in feeding ability, decreases in risk aversion, and decreases in adaptability to the environment, which can lead to death [ 21 ].…”

Fish not only constitute an important trophic level in aquatic ecosystems but also serve as an important source of protein for human beings. The health of fish is related to the sustained and healthy development of their entire aquatic ecosystem. Due to the widespread use, mass production, high disposal frequency, and degradation resistance of plastics, these pollutants are released into aquatic environments on a large scale. They have become one of the fastest growing pollutants and have a substantial toxic effect on fish. Microplastics have intrinsic toxicity and can absorb heavy metals discharged into water. The adsorption of heavy metals onto microplastics in aquatic environments is affected by many factors and serves as a convenient way for heavy metals to migrate from the environment to organisms. Fish are exposed to both microplastics and heavy metals. In this paper, the toxic effects of heavy metal adsorption by microplastics on fish are reviewed, and the focus is on the toxic effects at the individual (survival, feeding activity and swimming, energy reserves and respiration, intestinal microorganisms, development and growth, and reproduction), cellular (cytotoxicity, oxidative damage, inflammatory response, neurotoxicity, and metabolism) and molecular (gene expression) levels. This facilitates an assessment of the pollutants’ impact on ecotoxicity and contributes to the regulation of these pollutants in the environment.
