“…Thus, the increases in parrotfish biomass observed here will likely to be beneficial for sustaining a coral dominated reef ecosystem. Consequently, our findings highlight how restrictions to water-based activities can lead to increased biomass of reef fish populations, suggesting that the implementation of restrictions through management strategies, such as Marine Protected Areas (MPAs), can be effective tools for enhancing fish populations 13 , 25 , 41 , 42 . In turn, higher fish biomass of key functional groups contributes to the ecosystem function of coral reefs 5 , 43 and the provision of ecosystem services 5 , 8 , 9 .…”

In March 2020, the world went into lockdown to curb the spread of the novel coronavirus (SARS-CoV-2), with immediate impacts on wildlife across ecosystems. The strict 2-year long lockdown in Grand Cayman provided an unprecedented opportunity to assess how the ‘human confinement experiment’ influenced the community composition of reef fish. Using a suite of multivariate statistics, our findings revealed a stark increase in reef fish biomass during the 2 years of lockdown, especially among herbivores, including parrotfish, with drastic increases in juvenile parrotfishes identified. Additionally, when comparing baseline data of the community from 2018 to the 2 years during lockdown, over a three-fold significant increase in mean reef fish biomass was observed, with a clear shift in community composition. Our findings provide unique insights into the resilience of reef fish communities when local anthropogenic stressors are removed for an unprecedented length of time. Given the functional role of herbivores including parrotfish, our results suggest that reductions in human water-based activities have positive implications for coral reef ecosystems and should be considered in future management strategies.

“…To safeguard this biodiversity, the Abrolhos National Marine Park was created, encompassing 880 km 2 . Marine protected areas (MPAs) are known to benefit population recovery by increasing the abundance and size of individuals, therefore contributing to egg and larval export (Félix‐Hackradt et al, 2018; Harrison et al, 2012), besides providing high‐quality habitat for settlement (Lima et al, 2023). By demonstrating that Abrolhos Marine Park serves as a settlement ground beyond being a refuge for the adult population, this MPA can contribute to sustainability of local fisheries.…”

The age and daily growth of fish are registered through the deposition of increments in their otoliths, which are concretions formed by the precipitation of substances present in the endolymphatic fluid, mainly calcium carbonate (CaCO3). Faced with the need to fill some of the gaps in the knowledge on the occurrence and duration of the initial stages of snapper species' life cycles in the Abrolhos Bank, this study aimed to describe the growth rates, age, and period of pelagic larval duration (PLD) of three snapper species during the larval pre‐settlement phase, in the Abrolhos Bank region. The post‐larvae were captured using light traps. Otoliths were removed from 117 samples of snapper species; however, only 69 were viable for age estimation, of which 15 were Lutjanus analis, 25 were Lutjanus jocu, and 29 were Lutjanus synagris. Together, the samples presented individuals with total lengths ranging from 16.14 to 24.76 mm and ages from 21 to 39 days. Settlement marks were found for all three species, and the average PLD was ~25 days. The somatic growth of the snapper species was positively correlated with otolith growth. L. jocu presented the greatest daily growth compared to the other species. The three species use the Abrolhos Bank as a larval settlement site, demonstrating plasticity by using different habitats throughout their lives.

“…We found associations between O&G platform proximity and fish abundance and fish body size similar to effects of marine protected areas (MPAs). MPAs are used for various purposes, including restoring fish populations through egg and larval export, and movement of adult fish to adjacent fishing areas (Harmelin‐Vivien et al., 2008; La Mesa et al., 2011; Lima et al., 2023; Medoff et al., 2022). Inside MPAs, fish may be more abundant and larger in body size (Rolim et al., 2019).…”

Globally, aging offshore oil and gas (O&G) platforms face resource depletion, and regulations often demand platform removal through decommissioning. In the North Sea, >€90 billion will be needed for decommissioning by 2060. However, the influence of O&G platforms on fish communities is poorly understood. This challenges predictions of possible fisheries scenarios associated with different decommissioning options. Here, we examined the role that North Sea platforms played on fish communities. We explored patterns of fish abundance and body size variation along transects from O&G platforms comparing catch per unit effort data. Fish abundance was positively associated with O&G platforms. Atlantic cod, plaice, saithe, and mackerel were most abundant near platforms. Similarly, larger Atlantic cod were near the O&G platforms. Our study provided information for decision‐making regarding platform decommissioning scenarios by evidencing O&G platform habitat provisioning for various commercial fish species.
