“…We validated the final model by simulating new data from the fitted model and examining the distribution of scaled residuals with the DHARMa package in R (Hartig & Hartig, 2017), following other applications of similar models (e.g., Smith et al., 2022). The distribution of the residuals was examined visually relative to all included and excluded covariates and among countries.…”

Threat mapping is a necessary tool for identifying and abating direct threats to species in the ongoing extinction crisis. There are known gaps in the threat mapping literature for particular threats and geographic locations, and it remains unclear if the distribution of research effort is appropriately targeted relative to conservation need. We aimed to determine the drivers of threat mapping research effort and to quantify gaps that, if filled, could inform actions with the highest potential to reduce species’ extinction risk. We used a negative binomial generalized linear model to analyze research effort as a function of threat abatement potential (quantified as the potential reduction in species extinction risk from abating threats), species richness, land area, and human pressure. The model showed that threat mapping research effort increased by 1.1 to 1.2 times per standardized unit change in threat abatement potential. However, species richness and land area were stronger predictors of research effort overall. The greatest areas of mismatch between research effort and threat abatement potential, receiving disproportionately low research effort, were related to the threats to species of agriculture, aquaculture, and biological resource use across the tropical regions of the Americas, Asia, and Madagascar. Conversely, the threat of linear infrastructure (e.g., roads and rails) across regions, the threat of biological resource use (e.g., hunting or collection) in sub‐Saharan Africa, and overall threats in North America and Europe all received disproportionately high research effort. We discuss the range of methodological and sociopolitical factors that may be behind the overall trends and specific areas of mismatch we found. We urge a stronger emphasis on targeting research effort toward those threats and geographic locations where threat abatement activities could make the greatest contribution to reducing global species extinction risk.

“…Cyclic hypoxia exposure, which may be found in diel patterns of aquaculture pens, accelerates the progression of AGD in post-smolts (Oldham et al 2020). Large Atlantic salmon have significantly lower gill parasite burdens and reduced AGD-related pathologies compared to small fishes (Smith et al 2022). Intense fish crowding in narrow depth bands can lead to increased AGD risk (Wright et al 2017).…”

With the increasingly global scale and scope of aquaculture, the need to match this development with improvements in fish welfare is a central societal and industry goal. We provide a comprehensive assessment of the farmed Atlantic salmon (Salmo salar) literature with targeted examples focusing on Atlantic salmon farmed in Tasmania, Australia. We synthesise insights from both small- and industry-scale perspectives, highlighting other reviews that provide discussions of particular sub-areas of farmed salmon research. We focus on recent advances and improved methods for farmed Atlantic salmon handling and management, behaviour, health issues and breeding. We also address wildlife interactions resulting from fish farming, as well as future research directions and system development. This review can serve as the basis for the development of aquaculture management guidelines that place individual fish welfare as a primary goal.
