Summary: Developing conservation and management strategies for species with complex life histories, broad spatial distributions, and long lifespans is difficult, especially when managers cannot identify critical habitats or vulnerable life stages due to migration scale or connectivity uncertainty. Otolith stable isotope micro-sampling is a useful tool for examining broad-scale movement and migration patterns of fishes. Results from comparing Crevalle Jack in different regions showed differences in ontogenetic movement patterns and connectivity.

Summary: This article discusses the life cycle strategies of anguillid eels and introduces methods for studying these strategies. The article points out that the current management framework for eels focuses mainly on freshwater environments, ignoring eels growing in saline waters. The authors argue that the ability of eels to shift habitats is crucial for the recovery of endangered species.

Summary: The anadromous estuarine tapertail anchovy (Coilia nasus) in the Yangtze River is a critically important species. This study investigated the population structure of C. nasus using otolith core trace elements and microsatellite markers. The results revealed distinct spatial and genetic separations among C. nasus populations in the Yangtze River Estuary and the Poyang Lake, highlighting the importance of protecting the spawning area of the mature C. nasus in the Yangtze River Estuary.

Summary: Developing a metapopulation framework contributes to the understanding of spatial processes and structures in populations, providing basic information for conservation biology. However, the extent to which the metapopulation structure differs geographically and across life history stages is unexplored for most fishes. Here, we compared the population structure and connectivity patterns of juvenile yellow snapper Lutjanus argentiventris in mangroves of the Eastern Tropical Pacific Ocean.

Summary: The study aims to evaluate the environmental strontium isotope ratio (87Sr/86Sr) as a potential natural tag to infer the natal origin and ontogenetic habitat use of salmonids in Patagonia, specifically Chinook salmon. The results showed that 87Sr/86Sr is a useful natural tag to trace the life history of migratory fishes in Patagonia.

Summary: This study examines the spatial population structure of capelin in West Greenland and finds that they mostly reside within one region throughout their life. The analysis of otolith microchemistry indicates the existence of local residency and segregation of populations. Unlike other North Atlantic capelin stocks, West Greenland capelin do not exhibit long-distance migrations.

Summary: This study used otolith microchemistry to estimate the fidelity of Columbia-origin Kokanee to their natal streams in the Williston Reservoir. The results suggest that there is some straying behavior among the fish, with a lower level of fidelity to specific natal streams. However, based on the similarity of water elemental signatures, a proportion of the fish is likely to return to their general region.

Summary: This study investigated the larval behavior and composition of diadromous freshwater fish in nine lowland lakes in the Lower Waikato region of New Zealand. The findings revealed that banded kokopu and giant kokopu were the most common species, with Lake Waahi consistently having the highest number of galaxiid captures. Analysis of larvae from Lake Waahi and other lakes showed that larger, older larvae were predominantly banded kokopu, while smaller, younger larvae were predominantly giant kokopu. The study also found that non-native zooplankton species, such as Daphnia galeata and Boeckella symmetrica, were the main components of the larvae's diet.

Summary: The small yellow croaker, an important commercial fish species, has experienced changes in its biological characteristics due to industrial-scale fishing. This study analyzed the elemental composition of otoliths from yellow croakers caught in the southern Yellow Sea and found uncertainty in their fidelity to natal or spawning sites.

Summary: The movement of small benthic fish, specifically the endangered small darter Percilia irwini in south-central Chile, is crucial for its management and conservation. Research shows that most movements occur in undisturbed parts of the catchment, with longer distances than previously thought, but no movements were identified in areas with altered connectivity due to human activity. This suggests that connectivity alteration may obstruct natural movement and further threaten populations' resilience. The study also discusses the use of microchemistry analysis for studying small benthic fish movement.

Summary: Partial migration strategies are common in populations of migratory animals and can be influenced by individual behaviors, genetic variation, or environmental conditions. Through studying multiple populations of a Hawaiian goby, it was found that stable stream conditions and variations in ocean hydrodynamics affect the prevalence of partial migration. A theoretical model further demonstrated the impact of flow and ocean dynamics on migration strategies.

Summary: The study focused on identifying nursery origins of individual Pacific halibut using otolith microchemistry. It found high assignment accuracy based on δ O-18, δ C-13, and Sr-88:Ca-48 ratios, with some mis-assignments to adjacent locations. The results emphasize the need for caution when using otolith microchemistry to assign fish origins, especially when baseline elemental data cannot distinguish missing nursery sources from included locations.

Summary: This study investigates the pesticide-related fish kills in brook trout populations in Prince Edward Island, Canada, and analyzes the life history and genetic inheritance of anadromy in sea-run brook trout. The results reveal that anadromy is mainly inherited from sea-run mothers, and the timing of freshwater entry is related to pesticide runoff.

Summary: The study used radiotelemetry to quantify the diel hydraulic habitat requirements of juvenile Sooty grunter in a river in northern Australia. Results showed a strong preference for shallow, fast-flowing mesohabitat and highlighted the potential effects of different river discharge scenarios on habitat availability. This study demonstrates the broad applicability of radiotelemetry in supporting the objective determination of environmental flow regimes for riverine fish.

Summary: This study evaluates key components of previous fish recruitment models by examining temporal and spatial variation in larval fish assemblages in a tropical Australian river catchment. The findings indicate that microfauna abundance, structural habitat complexity, and temperature are the most important predictors of larval fish abundance and diversity. The highest larval diversity occurs when discharge is highest.

Summary: The study found that intraspecific trait variability can contribute up to 70% of the total trait variability in freshwater fish species. The magnitude of intraspecific trait variability varies across different hydrological conditions, with intermittent streams having higher intraspecific trait variability than perennial rivers. Understanding intraspecific trait variability is important for predicting the effects of environmental changes on community assemblages and ecosystem processes.

Summary: The impacts of mine contaminants on ecological connectivity in rivers and streams are poorly documented globally. This study used acoustic telemetry to evaluate and refine conceptual models of fish movement in Magela Creek, a stream in the wet-dry tropics of Australia. The results demonstrate that Magela Creek provides wet season habitat for fish and acts as a migration pathway that connects lowland reaches and floodplains to upstream dry season refuges.
