Summary: Longitudinal movement plays a crucial role in the habitat colonization and population establishment of riverine fish species. However, the fine-scale movement patterns and recruitment habitats of amphibious fish species are still poorly understood. This study analyzed the ear-bones of Galaxias maculatus to assess its fine-scale longitudinal movement variability and found that it predominantly recruits in freshwater and estuarine habitats, with slow-flowing or stagnant habitats providing suitable prey for its larvae.

Summary: The study investigates the origin of eels caught in coastal waters of Estonia and Finland, as well as estimating the restocked eel escapement from Narva River Basin District. Results show that only a small percentage of coastally captured eels were originally restocked to NRBD, suggesting restocking eels to freshwaters may be ineffective, and restocking eels to coastal waters directly connected to the sea may be more successful.

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: Alternative migratory tactics in salmonids vary from strict residency to uninterrupted anadromy. Investigating Arctic charr populations, it was found that most individuals start migrating in their fourth year, but there is a large age variation. Skipped migrations are rare, indicating that annual migrations are the preferred strategy under current environmental conditions.

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: Our study found that faster-growing Dolly Varden tended to become either residents or early smolts, while slower-growing fish were more likely to smolt later in life. This contrasts with life history theory where the fastest-growing individuals in a population should mature as residents. Our results suggest that factors other than growth may play a significant role in influencing life history decisions in Dolly Varden.

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.
