Summary: Research shows that road-stream-crossing culverts can delay the migration of alewife and blueback herring, despite high passage rates. The delay in upstream migration more than doubled the time required to traverse the river. Additionally, the presence of snapping turtles ambushing fish in one culvert led to reduced passage rates, highlighting the potential cascading ecological consequences of physical barriers and the importance of a holistic approach to understanding barrier effects.

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 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: This study observed hydroids consuming pelagic fish eggs and used COI metabarcoding to identify the predator and prey species. The predator was determined to be Ectopleura crocea, and the prey species were Sillago japonica and Parajulis poecilepterus. Additionally, four arthropod species were consumed.

Summary: Predators can impact population and community dynamics through direct predation and nonconsumptive effects, such as changes in prey species traits. However, little is known about how kairomones act on prey across diverse aquatic ecosystems. This study explored how predator and prey identity and species composition influenced the expression of inducible defenses in water fleas.

Summary: The study provides insights into the foraging habits of Indo-Pacific bottlenose dolphins in south-western Australia, showing selective feeding behavior with a preference for Gobiidae species. Stable isotope analyses revealed niche differentiation between coastal and inshore dolphins, with coastal dolphins having a more pelagic diet and inshore dolphins feeding on enriched prey typical of estuarine environments.

Summary: After invasive fish are detected by native predators, their antipredator behaviors can shape their role in the invaded community and contribute to the success of the invasion. Comparing the behaviors of invasive and native fish species, it was found that the invasive fish were equivalent to or more profitable prey for native predators, facilitating their integration into local food webs.

Summary: Environmental forces can lead to synchronization among populations, but anthropogenic climate change may enhance synchrony across disparate populations. The consequences of population synchrony, such as impact to competitors and predators, are seldom considered.

Summary: The littoral zone of shallow water bodies plays an important role in predator-prey interactions, with sediment serving as a refuge for planktonic microcrustaceans. The study showed that the assemblage and size structure of crustaceans and fish, as well as biotic interactions, vary along the heterogeneity gradient of the littoral zone. This research contributes to understanding the defense strategies developed by zooplankton against predators.

Summary: Forage fishes play a crucial role in transferring energy in the food web. Understanding how they control the dynamics of the ecosystem is essential, especially in the face of climate change. The study focused on northern anchovy, an important forage species in the northeast Pacific, and found that its habitat suitability correlated with the diet and distribution of marine predators. The findings highlight the relevance of species distribution models in ecosystem-based management.

Summary: The contamination of freshwater environments by pharmaceuticals, such as fluoxetine, can disrupt the predation behavior of fish and the growth of their prey, water fleas. This study found that exposure to environmentally relevant concentrations of fluoxetine resulted in larger water fleas but altered hunting behavior in fish, with shorter reaction distance and slower feeding rate. These effects occurred regardless of water flea size and treatment regime.

Summary: Insufficient sampling has led to scarce data on abundance and distribution of forage fish. This study used video trawl survey data to document the abundance and distribution of northern sand lance in Stellwagen Bank National Marine Sanctuary, as well as the spatial overlap with Atlantic cod. The findings highlight the potential of video trawl data in monitoring and understanding fluctuations in forage species and supporting ecosystem-based management.

Summary: The apple snail Pomacea maculata has successfully colonized the Ebro Delta in Spain, despite efforts to eradicate it. This invasive species has negative ecological and economic impacts, but it can also provide a potential food resource for native and exotic predators. This study identified several potential predators through stable isotopic analyses and confirmed that certain bird, frog, crustacean, turtle, and mammal species consume the apple snail. However, it was found that fish species do not consume the snail under natural conditions, despite previous observations in laboratory settings. Further research is needed to understand the establishment of new trophic relationships and the potential of predators to act as biological control agents in nature.

Summary: Stable isotope analysis is a powerful tool in studying the diets of pelagic predators. The use of ethanol as a preservative for biopsy samples is still debated, as it may affect the trophic interpretation of stable isotope values. Lipid extraction is also commonly used, and this study examines the effects of ethanol and combined ethanol and lipid extraction treatments on stable isotope values in pelagic predators.

Summary: This study examined the physical and ecological factors affecting herring passage through a tide gate, finding that herring passage success rate varied with the season, key behaviors were influenced by diel period, tide, and flow direction through the gates, and these behaviors shifted as the season progressed, potentially due to predator avoidance leading to passage failure in the late spawning season.

Summary: The construction of dams and tide gates on waterways has impacted the physical structure of coastal, estuarine, and freshwater systems, affecting fish populations, particularly migratory species. These anthropogenic structures can hinder fish migration and alter their behavior patterns. Studying the behavior of fish around such structures is crucial in understanding the ecological impacts and relationships in varying environmental conditions.

Summary: This study analyzed the steady swimming kinematics of different fish species and found that they can be represented using parsimonious models. The segment configuration of the models is directly related to swimming kinematics, body shape, and Reynolds number. The study also identified shape parameters that can predict segment configuration, with head morphology being a good predictor of segment length. The bio-inspired multi-segment models can be used for designing fish-inspired robots, modeling hydrodynamic forces, and predicting muscle activation patterns during swimming.
