Summary: Research indicates that fishing pressure is the dominant driver of size spectra slopes in coral reef fishes, with carnivores being more heavily impacted as pressure increases. Additionally, habitat structural complexity plays a role in influencing the size spectra slopes of herbivorous fishes in coral reefs.

Summary: People's preferences and choices around food directly influence their resource use and the resilience of natural systems. The study found that reef fishes are now a significant part of local diets in the Maldives, with changing preferences potentially impacting reef ecosystems. Seasonal spikes in local catch and consumption of reef fishes, as well as an informal sharing network, were documented in the study.

Summary: Ocean warming has widespread impacts on coral reef ecosystems, affecting food webs and ecosystem function. The direct impacts include increased metabolic rates of fishes and invertebrates, while indirect impacts result from loss of habitat quality due to coral bleaching. The study found that changes in biomass with warming were primarily controlled by the direct effects on growth rates, rather than indirect effects on coral habitat. Crucially for fisheries, the biomass and productivity of predators decreased significantly with warming.

Summary: Restoration is a promising tool for coral reef conservation, but concerns about cost and ecological setbacks remain. Integrating reef ecology with restoration efforts can help address these concerns. This study examined the relationship between herbivorous fish communities, grazing intensity, and coral nursery performance, highlighting the importance of protecting key grazers and placing nurseries in areas with high fish biomass.

Summary: Current coral reef future models rely on threshold (TM) and multivariate environmental variability models (VM), with VM based on General Additive Model showing more accurate predictions for coral cover by considering significant environmental and fisheries management variables and determining that common predictive variables are weak or not significant predictors of coral cover. By comparing the predictions of the two models for future coral cover, it was found that the VM is more accurate than the TM in predicting coral cover in 2050.

Summary: Inshore coral reefs face various threats and disturbances, and marine protected areas with different fishing restrictions have been implemented to protect them. A study comparing fully protected, partially protected, and open fishing zones on the Great Barrier Reef found that full protection had a strong positive effect on targeted fish biomass, while partial protection had a comparatively modest effect. Fully protected zones had more than three times the biomass of highly targeted coral trout compared to open fishing zones. Structural complexity was an important factor driving fish biomass in all zones.

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 discovery of fossils in Mayan tombs has fundamentally altered our understanding of the earliest origins of coral reef fishes and reconciled the conflict between fossil and phylogenetic evidence. These fossils indicate that the origins of reef fishes can be traced back to Mexico, just 3 million years after an asteroid impact, and reveal new insights into their early biogeography.

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: This study investigates the expression of visual pigment gene (opsin) in coral reef fishes and finds that algivorous species with orange/red colors exhibit high expression of long-wavelength-sensitive (lws) opsin. This enhances their ability to detect algae and orange/red-colored conspecifics, possibly enabling social signalling.

Summary: The study found that the coral reef ecosystems in the Arabian Gulf underwent long-term ecological changes following heat shocks, including a phase shift from predominantly reef-building corals to barren grounds. Macro-invertebrates responded rapidly to these changes, while fishes exhibited lagged responses. Increased levels of herbivory may have suppressed macro-algae expansion, leading to the dominance of barren ground.

Summary: This study evaluates the impact of considering ageing error and growth variability on the determination of input sample size (ISS) in statistical catch-at-age assessment models. The results show that including these sources of uncertainty decreases the ISS determined through bootstrap methods. This indicates that there is more variability in age composition and conditional age-at-length data than previously accounted for. Including these sources of uncertainty improves the estimation of ISS and subsequently improves the quality of stock assessment models.

Summary: Recent advances in genomics have greatly contributed to the assessment of fish stocks by providing precise identification of genetic boundaries. This study used a genotyping-by-sequencing approach to reveal the existence of an additional genetic cluster of blackspot seabream in the northeast Atlantic, which was not previously identified. Factors such as ocean circulation patterns and local upwelling may play a role in the genetic differentiation observed in this study.

Summary: Estimating growth is important for fish population assessment. Integrated assessment models and the influence of misfitting size composition data have renewed interest in how growth is modeled. The available data types control how the length-at-age relationship is estimated. Estimating length-at-age is complex due to multiple sources of biological variability and difficulties in obtaining representative samples.

Summary: Small-scale fisheries are vital for global food security and cultural heritage, but the lack of information hampers effective management and mitigation of ecological impacts. This study provides the first comprehensive overview of the small-scale fishery fleet in Northern Cyprus. The fleet operates mainly over the continental shelf, using static and demersal gear types, and catches a diverse range of species, some of which are threatened. The findings can be used to improve fisheries management and conservation measures.
