Summary: Through the analysis of data collected over the past 30 years by scientists from the UK, Germany, France, and Ireland, as well as observations from multinational Citizen Science, it was found that the spawning grounds of L. forbesii form an external semi-circle around the spawning grounds of L. vulgaris, and L. forbesii utilizes the North Sea more extensively than L. vulgaris. Seasonally, the position of the spawning grounds is influenced by local temperature conditions, with spawning occurring from November to July.

Summary: Female size affects fecundity through both batch fecundity and spawning frequency, with smaller females potentially nullifying the hyperallometric contribution of larger females. Spawning frequency scales positively with body size across species, while the relationship between body size and absolute fecundity may be underestimated based on batch fecundity estimates. Further studies are needed to better understand the impact of female size on reproductive output.

Summary: The marine environment is impacted by the pollution of microplastics, which tend to accumulate on the seafloor. In this study, sediment samples from different seafloor habitats in the Cabrera Marine-Terrestrial National Park were analyzed to investigate the distribution of microplastics. The results revealed that the abundance and shape of microplastics varied among different seafloor habitats, with sandy habitats showing the highest concentration.

Summary: Capelin is a short-lived forage fish species that experienced a population collapse in 1991 on the Newfoundland and Labrador Shelf. The collapsed stock is characterized by delayed spawning timing and low recruitment. This study compares inter-annual trends in temperatures, timing of spawning, and annual larval densities between two northeastern bays (Trinity Bay and Notre Dame Bay) and investigates the habitat quality and larval densities between subtidal and intertidal sites in Notre Dame Bay.

Summary: In the last decades, climate change and human pressures have had a significant impact on the ocean, leading to the urgent need for actions to protect coastal marine ecosystems. The European Commission has set ambitious targets for member states through the Water Framework Directive (WFD) and Marine Strategy Framework Directive (MSFD). This study compared the performance of 11 biotic indices in assessing the environmental status of the Marine Protected Area (MPA) of Capo Carbonara and found that all indices were consistent in confirming the good status of the MPA.

Summary: Marine Protected Areas (MPAs) are crucial for maintaining ocean ecological processes and associated ecosystem services. This study assesses the potential risks for habitats and recreational activities in a subtropical MPA, focusing on the Queimada Grande Island in southeastern Brazil. The study finds that the coral reef and its adjacent habitats provide important cultural ecosystem services but are also at high risk of impact. The effective management scenario is found to be the application of regulations present in the MPA management plan.

Summary: Established in 1995, Cabo Pulmo National Park has seen a significant increase in fish biomass. A study using an unmanned aerial vehicle (UAV) found lemon sharks, bull sharks, and Pacific nurse sharks in shallow coastal habitats, with sharks being more common in the afternoon, potentially using warmer shallow areas for thermoregulation. This highlights the efficacy of UAV surveys for species identification compared to previous terrestrial surveys.

Summary: The study aimed to trace the life history of escaped meagre through otolith microchemistry, finding similar patterns of strontium concentrations between farmed and escaped fish but differences in barium concentrations at specific periods. Differences in otolith Sr:Ba ratios between farmed and escaped meagre suggested they shared the same origin but inhabited different conditions from a certain time of their life. However, individual differences in core-to-edge Sr:Ba values among escaped fish indicated they escaped in different periods, showing the potential of otolith microchemistry as a tool to trace escaped fish.

Summary: Excessive phosphorus in fish feed can harm metabolism and increase waste in farm effluents, impacting aquatic ecosystems. Both phosphorus deficiency and excess can cause skeletal deformities and issues with mineralization in fish.

Summary: The present study aims to investigate the effect of two feeding schedules on the early development and physiology of seahorse Hippocampus reidi juveniles. The results indicate that extending the feeding period on copepods improves the welfare and condition of juveniles. However, switching from copepods to Artemia nauplii at earlier developmental stages leads to lower growth rates and survival.

Summary: The ocean plays a crucial role in the Earth's dynamics and provides ecosystem services to humans. However, human activities are causing changes in the ocean's structure and biodiversity. The United Nations has proclaimed a Decade of Ocean Science for Sustainable Development, and acoustic animal tracking is identified as a method to achieve Sustainable Development Goal 14. Acoustic tracking can be used to monitor and reduce marine pollution, study the effects of human-made structures on biodiversity, and contribute to sustainable fishing and spatial protection targets.

Summary: The European hake is a valuable species in the North-East Atlantic and the Mediterranean fisheries. However, careful management is needed as it has been rated as overexploited in the Mediterranean. This study assessed the discrimination capability of otolith shape and microchemistry in distinguishing different sub-populations of Mediterranean hake. The results showed significant between-unit differences, but overall discrimination capability was poor, indicating a continuous gradient rather than distinct spatial units.

Summary: The Galician Rias in northwestern Spain are affected by harmful algal blooms, which challenge aquaculture activities. This study presents a satellite imagery approach using Sentinel-2A/B satellites for monitoring reddish blooms of Noctiluca scintillans and Alexandrium spp. The approach offers a simple and feasible method to accurately map blooms in the study area, useful for monitoring and aquaculture management purposes. However, Sentinel-3A/B satellites with a coarser spatial resolution do not accurately detect small bloom footprints, despite suitable multispectral bands.

Syngnathids preferred different habitats in each park, with S. abaster dominant in PNAC and S. acus dominant in PNIA. Further studies are needed to explore the potential species complex in S. abaster and migration events in PNIA.

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.

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.

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.
