Summary: The study investigated the species composition and assemblage structure of ichthyoplankton in Sansha Bay, revealing dominant taxa including commercially important fishes such as Gobiiformes, and highest density and richness occurring in May. Temperature, salinity, and chlorophyll a were identified as key factors structuring the ichthyoplankton assemblages in the bay.

Summary: Our study shows that DNA metabarcoding is an effective method for monitoring changes in fish larvae abundance and community composition. It is a feasible, efficient, and faster alternative to traditional morphological methods, suitable for both terrestrial and aquatic habitats.

Summary: This study investigated the larval distributions of small-sized fish species in the East China Sea ecosystem, highlighting their preference for specific depths and environmental conditions. The migration patterns of certain species were also observed. These findings have important implications for the preservation of spawning and nursery grounds, as well as the management of sustainable coastal fisheries.

Summary: This study identified fish eggs collected in Guanghai Bay through molecular and visual taxonomic methods, and discriminated four economically important species. The validity of the identification results was verified through phylogenetic analysis and BarcodingR package methods. The study provided morphological characteristics and detailed photographs of the eggs, as well as described the developmental characteristics of each species. These results are crucial for egg discrimination and estimation of spawning areas, and contribute to the stock assessment and fishery management in Guanghai Bay.

Summary: This study successfully extracted DNA from fish larvae collected in the South China Sea using large-scale ecosystemic sampling, identified 101 species, and demonstrated the potential of using formalin-fixed samples for DNA recovery. The high-quality larval photographs provided valuable reference for identifying fish species during early stages based on morphological characters in the SCS.

Summary: Co-management has shown to bring significant changes in the composition and structure of fish assemblages in floodplain lakes of the central Amazon Basin. By regulating gear use and fishing practices, co-management led to the colonization of new species, resulting in higher richness, abundance, and biomass of fish. No-take zones and limited-access lakes provided potential spillover effects to open fishing lakes, showing positive effects of co-management regardless of zoning category.

Summary: The assessment of microlitter distribution and composition in the sea is a major challenge, where biological indicators can be an important tool. Research on multiple fish species revealed differences in microlitter ingestion between surface and bottom compartments, providing insights into microlitter levels in different parts of the water column. Analysis of microlitter fragments using Fourier Transform Infrared Spectroscopy helped to allocate species to their respective compartments based on expected buoyancies.

Summary: This study characterized the benthic assemblage composition of seamounts and oceanic islands in the South Atlantic Ocean, finding distinct differences between temperate and tropical regions, with latitude and depth identified as key environmental drivers. Faunal assemblages are similar to those observed in the North Atlantic in terms of functional groups.

Summary: This study investigated the relationships between large fish aggregations in the overwintering fishing grounds of the East China Sea in 2017 and environmental factors using satellite-derived and reanalysis data. It was found that abnormal temperature changes in the winter of 2017 may have been associated with changes in local ocean circulation.

Summary: Despite their remote location, deep-sea species have the ability to accumulate mercury, mainly in the form of the neurotoxin methylmercury (MeHg). The concentration of MeHg increases with the depth of occurrence of fish, and is influenced by their habitat. MeHg can be used as an indicator of a species' trophic position in the food web.

Summary: The study found that metal concentrations in water and sediment in the Zhoushan Fishery were generally below safety thresholds, except for Cu, As, and Cr in sediment. High levels of metal contamination were found in the west of the fishery, likely due to pollution from large international ports and chemical industries in Hangzhou Bay. Despite some exceedances of metal thresholds in crustacean species, a health risk assessment indicated that seafood consumption from the area is safe, with a potential risk for local consumers who prefer crustaceans.

Summary: Despite previous research, the structure of helminth communities among fish populations in the Azov-Black Sea region remains poorly understood. This study presents data on the species diversity and structure of helminth communities in 12 common fish species from the coastal waters off Crimea. The communities showed low species richness and diversity indices, but were well-aggregated and followed a core-satellite distribution. These findings expand our knowledge and have implications for monitoring and managing local fish stocks.

Summary: A study on the West Florida Shelf used DNA metabarcoding to identify fish eggs from 49 stations. They found 37 different taxa from 4,719 fish eggs, and the distribution of eggs corresponded with known habitat types. Metabarcoding was faster and cheaper than barcoding individual eggs; however, it had limitations in determining absolute taxon proportions and detecting contaminating DNA. The study also reviewed the advantages and disadvantages of using metabarcoding vs individual fish egg barcoding for long-term monitoring programs.

Summary: Arctica islandica is an important species for recording climate change on the U.S. northeast continental shelf, and its growth rates show synchronous changes with cold and warm climatic periods. This study finds that A. islandica near the Delmarva Peninsula had higher growth rates during cold periods, possibly due to increased food supply in shallower water. The range recession of this species is a long-term process determined by the survivorship of older individuals.
