“…We also used a word cloud analysis to visually evaluate ornamental fish keepers’ perceptions regarding the release of ornamental fish in the wild. This technique makes it possible to identify which words were most frequently cited by the participants ( McNaught & Lam, 2010 ; Barbosa-Filho et al, 2020 ). All analyzes were performed using the R software version 3.6.1 ( R Core Team, 2019 ).…”

Background The use of ornamental fish as pets has important implications for the conservation of the species used in fish keeping, particularly in relation to overexploitation. Understanding ornamental fish keepers’ relationship with the hobby can provide important information for assessing the potential impacts of the activity. Here, we analyzed the profile of Brazilian ornamental fish keepers and evaluated their preferences and the implications of their choices. Methods Information was obtained by applying questionnaires to 906 ornamental fish keepers participating in fish keeping groups in a social network. The questionnaire contained questions about the species of fish kept (freshwater and marine), techniques used, socio-economic aspects, and associated conservation perspectives. Results Most ornamental fish keepers were young men (20–40 years old), with higher education and monthly income above US$ 530.00. Participants predominantly kept freshwater fish (86%), but marine fish only (5%) or both marine and freshwater hobbyists (9%) were also recorded. A total of 523 species of ornamental fish were kept, most of which comprised freshwater (76% of the total) and exotic species (73%). About a third of the fish species recorded were under national trade restrictions. In addition, about a third of ornamental fish keepers declared that they also had invertebrates. Marine aquariums require a greater financial investment, especially at the beginning, than freshwater aquariums and are also almost entirely based on exotic species. The aesthetic factor is the main motivation associated with practicing this hobby, being color and behavior key factors in choosing fish. A total of 10% of hobbyists have already released fish into the wild, highlighting concerns about potential biological invasions. There is an urgent need to enforce regulations towards restricting ornamental fish keepers’ access to threatened native species and potentially invasive species, as well as measures aimed at informing and raising hobbyists’ awareness of conservation measures related to the hobby.

“…"conservation," "conserve") were grouped and the respective connotations (positive, negative, or neutral) were determined based on open discussion between the authors to achieve a consensus. A word cloud-employed for the analysis of qualitative information across various disciplines, including that of environmental management (Marchese et al 2018;Barbosa-Filho et al 2020)-was constructed to visualize the most frequently used words (R packages "wordcloud," "XML," "SnowballC," "tm," "RCurl," "RColorBrewer"; Fellows 2012; Lang & Lang 2013;Bouchet-Valat 2014;Neuwirth 2014;Lang & Lang 2016;Feinerer & Hornik 2019).…”

Coral restoration has largely focused on improving techniques and biological yield to hasten reef recovery. However, as socioeconomic considerations can affect restoration success, it is important to also consider inputs from various stakeholders in the design and execution of restoration projects. Through online questionnaires, the knowledge levels and attitudes of 142 participants toward coral ecology and restoration in Singapore, and their preferences toward species traits they felt were most beneficial for restoring reefs, were analyzed. Comprising varied sociodemographic profiles and stakeholder groups, participants fared better in general coral biology (up to 90% of answers correct) than local coastal resource management (35% of answers correct). More than 79% of participants agreed that Singapore's reefs were rapidly degrading and required restoration to slow the decline; however, over 63% of them disagreed that restoration was the sole domain of scientists or that the topic had been sufficiently communicated to the public. These knowledge scores and attitudes were most influenced by stakeholder group, educational level, and familiarity with local reefs, underscoring the need to improve environmental education and science communication to these groups. In the trait prioritization exercise involving 76 respondents, resilience and resistance to stress were regarded as most important for restoring reefs. Marine science professionals and nondivers preferred using species that could cope with stress, while nature enthusiasts and recreational divers considered habitat contribution by various coral growth forms as more important. The adaptable framework here facilitates integration of stakeholder inputs with the necessary strategies to boost restoration outcomes.

“…Free sale and illegal use also increase the number of nets left in the ecosystem, whether intentionally or not (Azevedo- Santos et al 2022), resulting in 'ghost nets' (Barbosa-Filho et al 2020, Vitorino et al 2022; see also Fig. 1d), which impact aquatic fauna ranging from invertebrates to fish to large mammals (Table 1), including in Brazil (Barbosa-Filho et al 2020, Azevedo-Santos et al 2021.…”
