“…However, research has shown that localised sheries yield can increase as a result of ARs, through increased production of commercial species 89, 90 , as well as MPA establishment, as a result of the 'spillover effect', as described and demonstrated by 91,92 . Some interviewees discussed this, such as I1, who said "[because of the MPA and conservation work] sh have come back to the area, particularly sh that are commonly consumed by local people, such as snapper sh.…”

Aside from their associated direct ecological advantages, coral reef conservation programs may also generate benefits to local communities. These communities may choose to support marine conservation programs based on multiple factors, and an increased involvement of local people often leads to positive changes in environmental behaviours. This study collected qualitative data using semi-structured interviews and multi-stakeholder focus groups on a rural fisher community in Tianyar Village, North Bali, Indonesia, where the ‘North Bali Reef Conservation’ (locally known as ‘Yowana Bhakti Segara’) coral reef conservation program was based. Results showed that generally, the community of Tianyar village was in support of the existing coral reef conservation programs, mostly due to the perceived economic prospects associated with being involved in the conservation work. Overall, the community agreed that the coral reef conservation program has led to societal and environmental benefits, which has generated positive environmental behaviours and a change in mindsets since it was established in 2017 (4 years before this study was undertaken). Based on the answers of interviewees, this study makes recommendations on how coral reef conservation in Bali (and other similar less developed nations) can increase community support, socio-economic benefits and positive environmental behaviours. These include (1) continuing environmental education for within the community, (2) strengthening regulations and improving enforcement, (3) increasing financial and logistical support for waste management and ecotourism, (4) continuing building and deploying artificial reefs, ensuring that ‘best practice’ recommendations are followed, and (5) utilising the influence of local leaders to create positive environmental behaviours.

“…Conservation acts include setting up regional freshwater conservation reserves or MPAs (Koning & McIntyre, 2021;Lenihan et al, 2021), or globally, the Convention on Biological Diversity. In situ conservation zones such as small grassroots reserves in the Mekong River systems (Koning & McIntyre, 2021) are usually localized and isolated, yet are important in protecting food webs and augmenting fisheries yields.…”

Conservation of genetic resources for sustainable aquaculture

The importance of conservation of aquatic biodiversity on sustainable fisheries is gradually being recognized by more and more people. Positive results have been reported from establishing marine protected areas (MPAs) as well as freshwater reserves (Koning & McIntyre, 2021;Lenihan et al., 2021). Conservation of aquatic animals and plants is not yet fully addressed in a way that will protect genetic resources for aquaculture purposes. The Food and Agriculture Organization (FAO) (2019) published a report about aquatic genetic resources based on surveyed responses from 92 countries. Most replies to the questions were positive and energetic, but it also revealed problems that limited efforts made to conserve the aquatic genetic resource.This editorial aims to call attention to conservation of genetic resources from an aquaculture perspective.Producers could consider practices that are more friendly to conservation of genetic resources. Management bodies may pay attention not only to biodiversity alone, but also to the genetic diversity important to sustainable aquaculture. Research plans could be prioritized to address important questions such as characterization of populations, optimizing fast and efficient genotyping and phenotyping tools, evaluating environmental factors and protection approaches not only for species richness but also genetic diversity, and estimating effects of stock enhancement programs on genetic components of wild populations. | GENETIC VARIATION AND SUSTAINABLE AQUACULTUREAquaculture species have two eminent features that make them highly suitable for selective breeding: high fecundity and high genetic diversity, because most species in aquaculture are still in the early stages of domestication (Houston et al., 2020). High genetic variation in wild populations is an important resource for selective breeding of aquatic species. The genetic resource of wild populations can contribute in various ways to sustainable aquaculture. First, wild alleles can be reintroduced to farmed populations if inbreeding occurs due to bottleneck effects in breeding practices. Second, if there is demand for new traits, such as resistance to disease, genetic materials can be accessed from selected strains as well as the wild populations. Third, there are still many other or "novel" species, particularly native species being tested for aquaculture, such as the fat sleeper (Dormitator latifrons) in Latin America (Vega-Villasante et al., 2021). Therefore, conservation of biodiversity and genetic variation of aquatic species is important for developing and maintaining good strains for sustainable aquaculture. Furthermore, comparison between different regional populations and farmed ones may aid understanding of genetic components that underlie aquaculture performance across different traits, such as identifying causative variants for target traits (Houston et al., 2020).

“…After the establishment of a MPA in an intensely-fished area, the biomass and body size of the target species generally increases through time within MPA boundaries (Halpern and Warner 2002;Harmelin-Vivien et al 2008). Other metrics like fish abundance and species richness may also increase (Vanderklift et al 2013), although such effects appear less general and more idiosyncratic than recovery of exploited species biomass, and are generally not considered as unequivocal indicators of MPA effectiveness Lenihan et al 2021).…”

The Influence of Boundary Habitat Continuity on Spillover from a Mediterranean Marine Protected Area

The effectiveness of marine protected areas (MPAs) to restore populations of exploited species, both within and outside of their boundaries through net movement of individuals (“spillover”), can potentially be affected by continuity of habitats across the boundaries. Sandy seabeds may reduce movement of reef-associated species across MPA boundaries, thereby increasing the ‘reserve effect’ while decreasing spillover. Underwater visual censuses were undertaken inside the Cerbère-Banyuls Marine Reserve (CBMR) (France) and adjacent non-protected areas to assess the influence of habitat on spillover. Total fish biomass and mean fish size were significantly higher within the MPA, but rapidly declined across the reserve boundary. Nevertheless, there was no indication of a sharper decline in biomass at the northern boundary where a habitat discontinuity was present relative to the southern boundary with continuous habitat. This result may reflect a number of complicating factors that make assessment of spillover potential difficult, and which may also lead to the uncertainty about which situations and how much spillover may contribute to fished populations outside reserves. In particular, the home range area of the key exploited species relative to the scale of the habitat mosaic, and potentially different levels of fishing pressure at each boundary likely contribute to variability. While the CBMR appeared particularly well-suited to investigating this question, resolving these issues and identifying general principles for where and how much spillover occurs will likely be difficult without a series of specially designed MPAs. This highlights a conundrum facing MPA establishment in the face of pressures to be successful for both biodiversity conservation and to offer fisheries benefits—the latter are clearly not ubiquitous, but a shortage of suitable MPAs that can be used as scientific tools for better understanding how and when these benefits may occur is precluded by a general lack of MPAs designed and managed for this purpose. The results of this study do, however, clearly highlight the biodiversity conservation benefits of the CBMR.
