In this meta-analysis, we elucidated the effects of global warming on spermatozoa functions, key determinants of male fertility. We recruited 245 data records from 20 studies spanning 20 cold- and warm-water fishes to identify the effects of IWT on sperm quality. Data were re-processed and re-analyzed to determine the overall effects of IWT on sperm kinetics such as percentage of motile spermatozoa (MOT), duration of spermatozoa motility (DSM), curvilinear velocity (VCL), straight line velocity (VSL), average path velocity (VAP), as well as on enzymatic activities for energy supply (EAES) and antioxidant enzyme activity (ANEA). The standardized mean difference was calculated for each study, with positive values indicating higher performance under IWT. Results showed that (a) the overall effect size for MOT was larger negative in cold-water fishes (−1.22) than in warm-water fishes (−0.95). (b) Each 1°C increase in the activation medium reduced MOT by 1.30% (cold-water fishes) and 3.47% (warm-water fishes). (c) IWT negatively affected DSM, decreasing it by 10 s (cold-water species) and 5.64 s (warm-water species) per degree of IWT. (d) Spermatozoa velocity (VCL and VSL) increased by IWT in warm-water species.

Regarding fish welfare, the study summarizes the current knowledge status of salmon coping abilities and welfare indicators in strong currents and waves. On the safety front, there has been significant progress in operational safety management, accident analysis, and emergency preparedness, all of which are crucial for human personnel in these demanding settings. Human safety and fish welfare also rely on structures and equipment, and recent research results include advances in environmental load analysis, vessel design, simulations of fish farms. Notably, the development of contact-free, autonomous lifting operations, and hole detection methods represents a significant leap in maintaining aquaculture infrastructure.

Here we reviewed the scientific basis behind this idea and found that it is not supported by observational and experimental studies. This idea indeed arises from carbon budget models that are based on theoretical misconceptions regarding seawater carbonate chemistry. The main misunderstanding consists of assuming that the carbon trapped in the shell originates from atmospheric CO<sub>2</sub> when it mostly comes from (bi)carbonate ions. While these ions originate from atmospheric CO<sub>2</sub> through the erosion of minerals over geological time scales, their incorporation into shells does not prompt short-term CO<sub>2</sub> compensation. The opposite occurs—calcification releases CO<sub>2</sub> in seawater and limits or even prevents the uptake of atmospheric CO<sub>2</sub>. Some authors suggest that considering the bivalve farm ecosystem could change the perspective on the source/sink issue but there is no evidence for that now. Most ecosystem-based carbon budget models rely on several unverified assumptions and estimates. Although challenging, field measurements must be conducted for monitoring, reporting, and verifying atmospheric CO<sub>2</sub> uptake before qualifying for carbon credits. To achieve scientific consensus, we need reinforcing measurement-based studies of CO<sub>2</sub> fluxes in shellfish ecosystems, integrating carbon balance models with observational and experimental science, and fostering interdisciplinary collaboration.

If chronic, these stressors can compromise their immune system, making fishes more susceptible to pathogens. Mortality and morbidity from infectious disease can result in considerable welfare impacts and massive economic losses for the industry, and the range of infective agents seen in ornamental species is well documented. However, treating these diseases is not straightforward with practices varying greatly across the trade and with several approaches having unintended consequences, such as the emergence of resistant strains of pathogens. While disease treatments for a handful of fish species (e.g., koi, goldfish) have received focused research attention, for the home aquarium owner, there is an increasing reliance on products based on natural compounds which have received far less scientific attention.
