TL;DR: Overall, the behavioral and neurobiological evidence reviewed shows fish responses to nociceptive stimuli are limited and fishes are unlikely to experience pain.

TL;DR: In this paper, the authors argue that the feelings-based approach to welfare is inadequate, inappropriate and must be rejected if applied to aquatic animals in wild capture fisheries, because it demonstrably ignores empirical evidence and several realities apparent within the natural aquatic environment.

TL;DR: It was reported that 6/20 unshocked crabs did not move but all (20/20) shocked crabs did move, and no control crabs showed ‘extreme responses’ but 4/20 shocked crab did.

TL;DR: Zebrafish captured with a net and held for 15 min at a water temperature of 27°C exhibited a subsequent preference to swim in water temperatures of 28.75 ± 0.27°C and higher for the next 4 h, compared with control fish that were neither captured nor held in nets.

TL;DR: In this article, Lopez-Luna et al. observed behavioral responses of larval zebrafish ( Danio rerio ) exposed for 10min to pH 2.6-3.6 when acetic acid (0.01-0.25%) or citric acid ( 0.1-5%) was added to the tank water in the presence or absence of aspirin (1−2.5 mg−l−1), morphine sulfate (1 −
