Summary: Observations of TeV halos associated with nearby pulsars suggest that these objects play a significant role in injecting high-energy electron-positron pairs into the interstellar medium, contributing to the cosmic-ray positron flux. This paper uses the cosmic-ray positron fraction from AMS-02 Collaboration to determine the characteristics of local pulsar population. The findings show good agreement between the measured positron fraction and model predictions up to energies of 300 GeV.

Summary: This article describes methodological aspects in defining the study population, sampling plan, and sample weighting and calibration of effective sample of the Brazilian National Survey on Child Nutrition (ENANI-2019). The study assessed breastfeeding, dietary intake, anthropometric assessment, and micronutrient deficiencies in children under five years of age through a probability sample with stratification and clustering. The data collected will support the promotion and implementation of public policies for children under five in Brazil.

Summary: The accuracy of fish growth estimates depends on how samples are collected. Random sampling is inefficient and rarely random, while proportional otolith sampling (POS) has been shown to produce more accurate estimates compared to fixed otolith sampling (FOS) under ideal conditions. However, the influence of variables such as sample size, fishery selectivity, and fishing mortality on sampling bias is unclear.

Summary: To conserve the fish population, a combination of legal, technical, social, and economic instruments, including royalties, must be used. Royalties are not only a source of budgetary revenue but also meant to prevent overexploitation of fishery resources. The modeling of this mechanism and the evaluation of its ecological impact are the goals of scientific research on this topic, which includes the use of biological, bio-economic, and ecological models.

Summary: Fixed-station sampling design is widely used in fishery-independent surveys, but its non-probabilistic nature makes it more uncertain to draw inferences on population. This study compared the performance of fixed-station sampling design with simple random sampling design in detecting temporal trends of species abundance. The results showed that fixed-station sampling design could detect seasonal trends, but its effectiveness varied with different species distribution patterns.

Summary: This study uses Bayesian time-series models to estimate the bycatch of humpback whales in the U.S. West Coast sablefish pot fishery, provides estimates for observed entanglements, and demonstrates the applicability of the Bayesian framework for a variety of data and problems. The U.S. National Marine Fisheries Service has started using these models to improve humpback whale bycatch estimates since 2019.

Summary: Mesopelagic fish species have the potential to be a valuable resource for various industries, but the economic viability of a potential fishery requires careful analysis of fishing dynamics and cost-structures. This study found a strong positive correlation between catch rates and vessel sizes, with high profitability for certain fisheries and challenges for others, highlighting the need for further investigation into realistic catches, trip durations, and economic requirements.

Summary: This study compared the suitability of three data types (individual-level data, weighted individual-level data, and aggregated data) for spatial cluster detection using spatial scan statistics. The results showed that the choice of data type influenced the detection results, with higher average positive predictive value (PPV) when using aggregated data compared to individual-level data, with or without sampling weights.

Summary: This paper presents a meta-analysis of sustainable fishery management strategies in the Philippines over the past 20 years. The analysis reveals that the themes of sustainability management in the fishing industry are predominantly socio-economic in nature, with a strong focus on social goals. The study also identifies the most similar and dissimilar fishery management themes based on clustering.

Summary: Fishery management relies on accurate forecasts of fish abundance and considers the impact of daily decisions made by fishermen. Research on the decision-making process of small vessel fishers is crucial due to their prevalence in many fisheries and vulnerability to various factors. This study outlines a methodology for identifying the factors affecting fisher decisions and success, using the example of under 10-meter fleet targeting sea bass in the UK. The results highlight the influence of wave height and fish price on fishing decisions and success, while individual vessel variations also play a significant role.

Summary: Understanding spatial population structure and biocomplexity is crucial for a species' resilience. Spatial population models are slow to incorporate dynamics, but exploring movement in marine fish populations is important. Simulation frameworks help elucidate the impact of movement and distributional shifts, with strategies to improve estimation accuracy.

Summary: The bigeye scad fishery surrounding the island of O'ahu in Hawai'i is heavily reliant on fishing boats working with spotter planes. By utilizing survey data from spotter planes, researchers were able to create fishery independent indices of bigeye scad abundance, which showed similar trends to fishery dependent indices. The western region of O'ahu had the highest abundance index, with clear seasonal variations observed.

Summary: This research examines the economic component of a bioeconomic model for the recreational fisheries of spotted seatrout on Florida's west coast. A survey assesses the value anglers place on changes to the bag limit and size limit for catching spotted seatrout. The study finds that these changes are necessary for maintaining a sustainable stock, and the estimated economic value per person per day is $20.24 for charter boat anglers and $32.54 for private boat anglers.

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.
