“…Only Bai et al reported that Pelteobagrus vachelli , the same family as P. fulvidraco , is a negatively phototropic fish [ 34 ]. This may be due to the fact that the phototropic behavior of fish changes according to the developmental stage [ 20 ]. The development stages of fish affect the different phototropic behaviors of fish.…”

“…For different light colors, fish have positive or negative phototropism varying degrees [ 18 , 19 ]. It is known, however, that fish’s visual system changes across different life stages, and phototactic behaviors undergo modifications [ 20 ]. Thus, fish phototactic behavior at different stages to different colors can be used as a reference for implementing aquaculture countermeasures in practical production.…”

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.
