Summary: Hybridisation with introduced species is a threat to native fish populations. Temporal isolation, as a mechanism of reproductive isolation, can limit or prevent hybridisation between closely related species. However, despite the spawning timing difference, substantial overlap in spawning seasons leads to ongoing hybridisation between Yellowstone cutthroat trout, rainbow trout, and hybrids.

Summary: This study explores the social and ecological outcomes of stream connectivity for stakeholders and Yellowstone cutthroat trout populations. The aggregation of mental models reveals an emergent pattern of increasing complexity as more types of stakeholders are considered, and also reveals gaps and linkages among different stakeholder knowledge areas. Additionally, the results from individual-based models suggest that the outcomes for Yellowstone cutthroat trout populations are most strongly influenced by their large migratory life history form and self-preference mating.

Summary: The native Yellowstone cutthroat trout (YCT) population in Yellowstone Lake has been significantly impacted by the introduction of lake trout and climate change. The decline in YCT spawning runs can be largely attributed to the changing climate since the 1970s, although the growing predation effect from lake trout became dominant. The population decline of YCT is closely related to the reduction in suitable habitats due to increasing drought in the region.

Summary: The study focused on the genetic mating system and reproductive success of Yellowstone Cutthroat Trout in a migratory population. Sexual selection was found to vary across sexes, with males having significantly higher mating success and reproductive success explained by mating success compared to females. The population displayed a polygynandrous mating system, and the interaction between mating success and total length best predicted relative reproductive success. Tests for inbreeding avoidance among breeding adults were inconclusive, but the breeding population was found to be genetically stable and diverse.

Summary: This study investigates how changes in predation risk, cover, and bioenergetics affect diel activity and habitat use patterns of sympatric rainbow trout and bull trout. Rainbow trout and bull trout primarily forage at dusk, but only rainbow trout respond to changes in cover. These findings have important implications for predicting habitat suitability and managing instream flows.

Summary: This study assessed the effects of temperature on various aspects of early development in rainbow trout, including hatching, yolk-sac absorption, larval metamorphosis, post-metamorphic growth, developmental morphology, and muscle cellularity. The results showed that incubating the embryos at 16°C yielded synchronized hatching but smaller and less developed individuals compared to incubating them at 8°C. Shifting the post-hatch larvae to different temperatures affected the length and weight of the fish, with an immediate and temporary effect on length and a persistent effect on weight. Different temperature regimes also influenced the hypertrophy of red and white muscles. Overall, this study provides new insights into the temperature-dependent changes in developmental morphology, muscle cellularity, and larval growth in rainbow trout.

Summary: The study explored the relationship between tyrp1a and tyrp2 expression and body colour variation in rainbow trout, revealing significant differences in expression levels of these genes in different developmental stages and tissues, as well as between wild-type and yellow mutant rainbow trout. The full-length cDNA sequences of tyrp1a and tyrp2 were obtained, encoding proteins with conserved domains. Amino acid sequence comparisons showed higher conservation among fishes, and qRT-PCR analysis indicated varying expression levels in different tissues and developmental stages, suggesting a close relationship between tyrp1a and tyrp2 expression changes and rainbow trout body colour variation.

Summary: This study aimed to investigate the effects of plant protein-based diets supplemented with different levels of taurine on rainbow trout growth performance, whole body composition, and histomorphological traits of the intestine and main organs. The results showed that moderate taurine supplementation can influence the weight gain and protein efficiency ratio of rainbow trout, and can also alter the lipid content of the fish body.

Summary: Over the past 30 years, landscape perspectives in riverine ecology have become increasingly popular, leading to the development of various approaches for conceptualizing, mapping and understanding 'riverscapes'. These perspectives now guide principles and approaches in inland fisheries and watershed management, with scientific literature on riverscapes growing rapidly in the last two decades, indicating their importance in freshwater science and management. The use of high-resolution, spatially intensive techniques in mapping physical and biological characteristics of rivers and floodplains has improved understanding of spatial patterns at various scales, essential for successful management of river ecosystems and implementation of conservation programs.

Summary: The removal of two large dams on the Elwha River in 2014 successfully restored anadromous salmonid populations. Research before and after the dam removal showed that multiple species of salmonids were able to migrate upstream, with notable increases in the range and abundance of adult Chinook Salmon and Summer Steelhead. The removal of the dams allowed fish access to previously blocked areas, resulting in significant changes in fish distribution and density.

Summary: Establishing realistic targets for fish community composition is necessary for evaluating the effectiveness of river restoration projects. This study used eDNA metabarcoding to assess fish community compositions in a restoration mitigation project area in Japan. Results showed that eDNA surveys provided more comprehensive and realistic short-term target species estimates compared to capture surveys. The detection of intraspecific lineages also increased the resolution of the eDNA surveys.

Summary: Given the need for cost estimating data and tools for dam removal prioritization, planning, and execution in the United States, this study compiled reported costs from 455 unique sources for 668 dams removed from 1965 to 2020. The total cost of these projects was $1.522 billion, with the median cost for dam removals being $157k, $823k, and $6.2M for dams of different heights. Factors such as dam height, annual average discharge, and project complexity were found to be important drivers of removal cost.
