Summary: Changes in fish assemblages after coral bleaching and mortality can affect fisheries, particularly fish productivity and turnover. In Seychelles, fish productivity increased on reefs recovering to coral-dominated habitats, especially in fished areas, while it remained stable on reefs that shifted to macroalgae-dominated regimes. The benthic recovery trajectory strongly influenced post-bleaching fish productivity, emphasizing the importance of herbivore and invertivore species in sustaining small-scale inshore fisheries following climate disturbances.

Summary: The study in Kenya examined the long-term consequences of managing overfished fisheries through gear restrictions or closures. The research found that while both interventions showed positive responses in catch per unit effort (CPUE) trends, the changes were more sustained in the closure-adjacent landing sites compared to the gear-restricted sites. This highlights the potential benefits of closures in preventing suboptimal yields and fisheries collapse in nearshore East African reefs.

Summary: The need to move toward marine ecosystem-based management is recognized globally. However, many countries, including South Africa, fail to effectively address multiple interacting pressures in their marine assessments and management. Integrated Ecosystem Assessment (IEA) is proposed as a tool to organize information and guide cross-sectoral management decisions. This study identifies the sectors and pressures with the highest impact risk in the South African marine territory, including fishing, shipping, and coastal infrastructure. The findings align with those of the recent South African National Biodiversity Assessment and highlight the importance of understanding local knowledge gaps to improve assessment accuracy and prioritize impactful sectors.

Summary: The degradation of shallow ecosystems has led to a need to study and understand the biodiversity and functioning of Mesophotic Ecosystems. However, most research has been limited to tropical regions and focused on species, neglecting other important aspects of biodiversity. By studying a subtropical island in the Atlantic Ocean, we found that fish communities in mesophotic black coral forests (BCFs) differed in functional structure compared to shallow reefs, indicating the importance of specific management and conservation strategies for preserving the unique biodiversity and functionality of mesophotic BCFs.

Summary: This study develops a comprehensive resilience framework to examine fishery systems across ecological, socio-economic, and governance dimensions, distilling and defining 38 attributes that confer climate resilience. The directionality and mechanism of these attributes depend on specific context, capacities, and scale, with evidence of interdependencies among them. However, meaningful quantification of the attributes' contributions to resilience in fisheries remains a challenge, as most studies focus on the ecological dimension.

Summary: Current best-practice policy recommendations for managing fish stocks involve maintaining modest fishing mortality, establishing marine reserve networks, and not subsidizing unprofitable fisheries. However, the effectiveness of these proposed approaches for maintaining fish stocks and biodiversity in marine seascapes is rarely evaluated. Both recommended and unrecommended fishing practices can have unexpected consequences on habitat fragmentation and metapopulation connectivity.

Summary: Effective solutions to the ongoing coral reef crisis will remain limited until the underlying drivers of coral reef degradation are better understood. This global-scale study reveals the relationships between key metrics of ecosystem states and processes on coral reefs and indicators based on key human-environment theories. The proximity of the nearest market has the strongest and most consistent relationships with these ecosystem metrics, and resource conditions tend to display an n-shaped relationship with socioeconomic development. The integration of different human-environment theories provides the best explanation for the ecosystem metrics.

Summary: This article provides a brief historical narrative of coral responses to climate change exposures, followed by a review of evidence from multiple-site field studies. The findings reveal that environmental variables, especially excess thermal exposure, play a crucial role in coral bleaching and mortality response. Two categories of investigations, focused on excess thermal stress thresholds (TM) or continuous variables (VM), were identified, with TM investigations receiving more citations and being used to identify future climate change impacts and sanctuaries. The study emphasizes the importance of considering additive and interactive mechanisms of causation in coral responses to exposure. Additionally, it points out that some important variables for predicting coral responses have been seldom studied or modeled. The future status and health of coral reefs is expected to be better than predicted by TM investigations.

Summary: The negative trade-offs between food production and biodiversity, as well as the positive relationship between functional diversity and productivity, are frequently discussed in conservation and sustainability science. A study of coral reef locations in the Western Indian Ocean found that management for multispecies-maximum sustained yield (MMSY) can increase both food production and species numbers. However, additional conservation mechanisms are needed to prevent species loss.

Summary: This study examines the potential impacts of climate change on fisheries and agriculture in coastal communities across five Indo-Pacific countries. The findings show that while both sectors are at risk, fisheries are projected to suffer higher losses. Most locations will experience simultaneous losses in both fisheries and agriculture, but climate change mitigation measures could help reduce this double burden. Lower socioeconomic status communities are more likely to be affected.

Summary: Coral reef artisanal fisheries play an important role in coastal communities' nutrition and economic wellbeing, but their management encounters conflicts between short-term food security and long-term ecological function. This study examines the tradeoff between nutrient capture and fish yields in different traps, finding that targeting small, nutrient-dense species can improve food security while using a gear that captures larger and more sustainable body sizes enhances nutrient yields in coral reef artisanal fisheries. However, it is important to consider the potential negative implications for ecological functions and reef recovery.

Summary: This study estimates fish standing biomass, biomass production, and biomass turnover for 1,979 tropical reef sites spanning 39 tropical countries. Based on these metrics, the study proposes a conceptual framework to guide spatial management interventions and optimize conservation efforts. The study finds that high turnover is associated with high human pressure and low primary productivity, while high biomass is associated with low human pressure and high primary productivity.

Summary: Sustainably managing fisheries requires evaluation of stock status, but many multispecies reef fisheries lack research and monitoring capacity to assess stocks against sustainable reference points. In this study, fish biomass data from >2000 coral reefs were used to estimate site-specific sustainable reference points for coral reef fisheries. The results show that >50% of sites and jurisdictions with available information have stocks of conservation concern. The study highlights the ecological benefits of increasing sustainability and provides a promising means for enhancing the sustainability of global coral reef fisheries.

Summary: Partially protected areas have become the primary form of spatial management globally for preserving ecosystem integrity and managing human use. This paper examines three case studies of partially protected coral reef fishery systems to evaluate the benefits and risks of using them as a management tool. The findings show that partial protection can enhance fisheries production, improve catchability, and alter the composition of fisheries yields. However, without adaptive management to ensure short to medium term benefits without compromising long-term sustainability, these changes also carry significant risks for ecosystems and fisheries livelihoods.
