The world's oceans are largely free from intensive farming, but momentum to intensify and expand mariculture--the cultivation of aquatic organisms in the ocean--is growing. Despite optimism that mariculture will create economic and nutritional benefits for humans, it can also generate a host of risks, including environmental degradation, harms to wildlife integrity and welfare, captivity effects, and shifts in how humans view the nonhuman world. Collectively, we refer to these four types of risks as "dewilding." In this systematic review, we searched Scopus and Web of Science for recent literature documenting mariculture's dewilding impacts to organize and collate this evidence under one unified framework. We find that mariculture's dewilding impacts are consistently documented, though often in isolation, and that captivity and conceptual dewilding impacts are recognized as potential harms far less than impacts on the environment and wildlife. Future work examining mariculture's dewilding impacts will be paramount to guiding human decision-making and activity going forward. [ABSTRACT FROM AUTHOR]

Aquaculture, fueled partly by claims of supporting food security, is experiencing unprecedented growth. Framing aquaculture as a monolith, however, overlooks its extreme taxonomic diversity. This paper assesses the welfare risks associated with that diversity, establishing seven species-level risk factors from involved parental care to long lifespans. Investigating these welfare risks across all aquatic species reported to the Food and Agriculture Organization (FAO) revealed an uneven distribution of risk, with extreme species-level risks in chordates, crustaceans, and cephalopod mollusks. Compared to species with fewer risks, species with extreme welfare risks were found to cost more and contribute the least to global production. This work challenges the notion that prioritizing animal welfare is incompatible with addressing food security and creates the possibility of identifying certain plant and invertebrate species, like seaweeds and bivalves, that minimize welfare concerns while providing affordability and accessibility. Going forward, proactive welfare approaches are needed to inform consumer choice and shape just and sustainable aquaculture policy. [ABSTRACT FROM AUTHOR]

This commentary examines how understanding animal culture--shared behaviors and knowledge transmitted through social learning--plays a role in advancing welfare practices for captive fishes. Despite extensive evidence of fishes' complex sociocultural capacities, their psycho-social needs remain underestimated and unmet in zoos and aquaria. We explore what considering fish culture might mean for welfare practices: diverse social learning opportunities, cultural development, and thoughtful group management. More knowledge about wild fishes' lives will help bridge the gap between their full, complex lives and current captive welfare practices. [ABSTRACT FROM AUTHOR]

Research focusing on motivation has consistently identified changes in motivational emphases as individuals age. However, whether these same patterns exist with respect to more domain-general conceptualizations of these motives has not yet been examined. Furthermore, researchers have not determined whether these differences in motivations across age groups are associated with differences in different measures of well-being. Using three cross-sectional samples, we examine the relative importance individuals place on different motivational domains across different age groups. In Studies 1a and 1b, we show that age is negatively associated with growth motive importance, but is unassociated with security, control, or epistemic motive importance. In Study 2, we show that older adults who do not show this de-emphasis of growth motives have significantly lower life satisfaction and lower self-reported flourishing relative to those older adults who do demonstrate the typical reduced emphasis. Implications for these findings for happiness across age groups are discussed. [ABSTRACT FROM AUTHOR]

A study published in Science Advances analyzed 2,048 species of reef fishes and found that the most at-risk species receive the least attention from humans. The research highlights the limited knowledge and experience that humans have with marine life, and the urgent need for increased attention and conservation efforts. The study used data from various sources to measure research effort and public attention for each species, and found that wide-ranging species and those used in fisheries and aquaculture attracted more interest. However, species classified as threatened or vulnerable received significantly less attention. The study suggests interventions such as prioritizing species labeled as data deficient or not evaluated for conservation assessment and exploring the causal dynamics between scientific knowledge, public attention, and conservation outcomes.
