“…This indicates that higher densities could be linked to increased ventilatory activity in largemouth bass while transport may not. A previous study found that the ventilation rate of variatus platys ( Xiphophorus variatus ) did not change after being transported for 7 h in plastic bags (Vanderzwalmen, Edmonds, et al, 2020). High‐density crowding (> 200 kg m −3 ) has previously been reported to increase ventilation rates in Atlantic salmon ( Salmo salar ) within 2.5 h (Erikson et al, 2016).…”

The live transport of farmed fish is an important practice in Chinese aquaculture due to consumer preferences in its domestic market. However, live transport can be stressful for fish and may cause many welfare issues. This study aimed to examine the effects of transport density on the welfare of largemouth bass (Micropterus salmoides). Adult fish were allocated to four experimental treatments in a two‐factor design (N = 5 groups per treatment). Factor one was stocking density of either 39 (low density) or 78 (high density) g L−1. Factor two was transport, with half of the fish groups exposed to simulated transport stress for 3 h using a motion platform, and the other half kept in static tanks for the same length of time. Baseline behavior and physiology were determined from a subset of fish after acclimation but before selection into groups and application of transport. To determine the effects of transport, stocking density, and their interaction on the experimental groups, physiological sampling and behavioral recording were carried out immediately after simulated transport, and water quality was measured both before and after transport. Changes in water quality were observed between two timepoints, with decreased dissolved oxygen levels and increased water temperature. Total ammonia nitrogen levels significantly increased in all treatments over time, particularly in the high‐density groups. Fish ventilation rates were significantly elevated in the groups kept at a high stocking density regardless of whether they also experienced transport stress. Fish transported at a high stocking density also showed more fear‐related behaviors such as freezing and thigmotaxis than non‐transported groups. Serum cortisol, catalase, and aspartate transaminase levels were significantly higher in the transported treatment groups compared to the baseline fish, but no difference was found for serum glucose, lactate, and glutathione peroxidase. We concluded that 3 h of simulated transport was stressful to largemouth bass kept at 78 g L−1, as evidenced by altered fish physiological and behavioral indicators of stress, as well as deteriorated water quality. Additionally, we identified a positive correlation between serum and skin mucus samples for cortisol, glucose, and lactate in transported fish, providing important information for developing less invasive methods for the welfare assessment of largemouth bass.

“…There are a wide range of studies on RAS technology, an intensive aquaculture system with water recirculation (Jia et al, 2016(Jia et al, ,2019Liu et al, 2018;Mota et al, 2019;Yogev et al, 2020), but there is inadequate information on welfare and stress resistance of ornamental fish reared in this intensive system (Vanderzwalmen et al, 2020). The present study evaluated the skin mucus immune and stress responses to thermal hypoxia stresses in a valuable ornamental fish, blue gourami (T. trichopterus) reared in both RAS and TPS systems.…”

“…Therefore, a subsample (~10%) of videos were analysed blind by 119 an additional observer (inter-observer reliability: Kendall's W coefficient: 0.99). From the 120 videos, any visible body and fin injuries were recorded for focal fish and given a severity 121 score from 0 -3 where 0 = no injuries and 3 = major injury (Vanderzwalmen et al 2019).…”
