Summary: The study found seasonal variations in larval and juvenile fish communities in the Mondego estuary and its adjacent coastal area, influenced by environmental factors like temperature. Juvenile recruitment patterns for different species suggest a different nursery function between the estuary and coastal area for early life stages.

Summary: Chemical contamination is a common threat to biota in estuarine and coastal ecosystems, particularly trace metals which can accumulate and negatively impact small invertebrates like zooplankton. It has been hypothesized that metal exposure could also affect the zooplankton microbiota, leading to further impairment of host fitness. To test this hypothesis, copepods were exposed to dissolved copper and their transcriptomic changes and microbiota alteration were assessed. The study found minimal gene expression differences in the copper-treated copepods compared to the controls, but significant changes in the taxonomic diversity and composition of the microbiota. These findings highlight the importance of considering the microbial component when evaluating the vulnerability of zooplankton to metal stress.

Summary: The Chinese tapertail anchovy, Coilia nasus, is an important anadromous fish that migrates to spawn every spring. We have successfully assembled a gap-free genome for C. nasus, which provides valuable information for understanding its genome structure and function. The availability of this reference genome will contribute to the management and conservation of this important species.

Summary: Estuaries are important habitats for coastal fish species, and the recruitment of larvae and early juveniles into estuaries is crucial for population persistence. This study found that settlement-stage A. japonicus prefer turbid water over clear water when recruiting into estuaries, suggesting that turbidity gradients play a major role in their recruitment.

Summary: The study measured mercury levels in tissues of various migratory fish species, with sea lamprey showing the highest mercury content. This poses potential risks to both human health and wildlife, serving as a reference point for future assessments.

Summary: The study found that offspring of anadromous brown trout grew better at higher temperatures, indicating a possible genetic factor rather than a maternal effect. Additionally, unlike previous studies on Atlantic salmon, egg incubation temperature did not influence later growth in brown trout.

Summary: The study assessed tropical coastal dynamics by measuring fish diversity in different habitats across three estuarine systems in the southwestern Atlantic. Different patterns of species occurrence and distribution were found between habitats and seasons, affecting taxonomic, phylogenetic, and functional diversity dimensions. Redundancy in functional diversity was observed among habitats in both dry and rainy seasons.

Summary: Rivers along the eastern seaboard of the United States and Canada are becoming increasingly contaminated with heavy metals, affecting the health and morphology of anadromous fish. This study found that alewife in the Tusket River have accumulated some heavy metals and experienced reduced body weight for length and spine abnormalities. These findings suggest the potential impacts of deteriorating conditions of rivers and their surrounding waters on anadromous fish species.

Summary: The study discusses a defense strategy of Cyclops vicinus, which thrives in winter due to lower fish predation activity. Abundant phytoplankton in winter supports the population growth of C. vicinus. Winter dominance of C. vicinus is an evolved defense mechanism to avoid fish predation, contributing to regional biodiversity and freshwater food web stability.

Summary: Anadromous Arctic char and their freshwater habitats in the Canadian Arctic, particularly in the Nunavik region, are vulnerable to the impacts of climate change. Inuit knowledge holders have provided valuable insights on the optimal spawning habitats for Arctic char, indicating the importance of rivers with specific depth, velocity, and substrate characteristics. By using fuzzy logic and local observations, a quantitative model was developed to predict the suitability of spawning sites, demonstrating the potential applicability of this methodology for other species with local or traditional knowledge.

Summary: The study found that increasing wood had a moderate increase in spawner abundance for all populations, with spring-run Chinook salmon showing the most significant increase in numbers; salmonids responded strongly to beaver ponds and floodplains; fine sediment reduction primarily benefited fall-run and spring-run Chinook salmon, with steelhead and coho showing less response.

Summary: Otolith chemistry showed significant differences between sampling sites, while otolith shape differences were also significant except for certain sites. The discriminant analysis success rate ranged from 33.3% to 100% for chemistry, and from 32.1% to 67.6% for otolith shape, indicating the potential limitations of using microchemistry on a small geographic scale.

Summary: This study presents, for the first time, data on the fish assemblage structure of ten temporarily closed estuaries (TCEs) along the south-western coast of India. The findings indicate significant differences in fish community structure among the TCEs based on species presence/absence, estuarine use, and feeding mode. The use of functional guilds and the Estuarine Fish Community Index (EFCI) successfully represent the ecological quality of TCEs, revealing functional similarities between fish assemblages despite taxonomic, physical, and chemical differences. The study also establishes a significant relationship between anthropogenic pressure, EFCI, and ecological quality of the TCEs using the Generalized Linear Model (GLM).

Summary: Domestication processes and artificial selection in farmed rainbow trout leave signatures at a molecular level, with identified genomic regions containing genetic variants related to growth, development, reproduction, behavior, and immune system traits. This study detected several SNPs associated with candidate genes in interesting regions, providing insights into genetic traits of commercial importance.

Summary: The study utilizes water quality monitoring data to analyze the seasonal and inter-annual variability in habitat for the copepod Acartia tonsa in Chesapeake Bay. Results show that the P-crit metric predicts the largest volume of unsuitable deoxygenated habitat over space and time, with dry conditions leading to a decreased extent of deoxygenated habitat. Although no clear relationship between copepod abundance and habitat availability was observed, the peak abundance of A. tonsa correlates with the extent of deoxygenated habitat using the P-crit metric.
