Fish Ecology and Management Studies

This study examines brown trout behavior in high-velocity flows using HMM to identify how flow velocity and spatial velocity gradient affect movement and avoidance responses.

The paper develops a statistical model and database to estimate sustainable harvest limits for native nongame fishes using production/biomass ratios and age-related data.

This study examines population changes in sea trout across different spatial scales in Scotland over 72 years, finding significant national declines but varied regional and district patterns.

The paper quantifies catch inequality in California steelhead fisheries using 11 years of angler report data, finding high inequality and developing a method to determine minimal sample sizes for robust Gini coefficient estimation.

The paper examines how early-life temperature affects recruitment success in Eurasian perch populations using long-term hydroacoustic data and thermal indices.

This study integrates conservation planning with behavioral theory and social values to improve mahseer conservation in India by addressing stakeholder attitudes, communication, and governance barriers.

The paper shows that social cues from hatchery salmon influence wild salmon migration timing, alongside environmental factors like temperature and flow.

The paper assesses the invasion risk of 15 non-native fish species in the lower Tigris Basin under current and future climate conditions, identifying high-risk species and their potential spread.

This study evaluates changes in fish food web topology and functioning over time, finding increased connectance, generalism, and decreased modularity, which affect ecosystem functions and human well-being.

Across 269 functional responses from 45 freshwater fish species, invasive species exceed non-invasive species only when sampled in their native range; introduced populations match non-invasive species.

The paper links juvenile life stage factors to adult age at maturity in Chinook Salmon using a Bayesian model, finding growth and timing factors more influential than environmental conditions.

This study models extinction risk and population viability in freshwater fish under climate change, showing increased threats to cold-water species and small coastal rivers.

The paper tests if larval sea lamprey size affects survival time when exposed to TFM, finding a significant positive relationship between length, mass, and survival time.

This study examines how release size, location, and timing affect freshwater survival and residence of hatchery-reared Chinook Salmon, finding that survival and residence time decline with size and vary by release location and timing.

This study examines how prey availability affects the movement, activity, and growth of European catfish in different aquatic environments.

The paper models how declining reservoir levels and warming temperatures in the Colorado River facilitated non-native smallmouth bass invasion and reproduction.

The paper examines declining salmon spawner monitoring in Pacific Canada, finding reduced data collection despite conservation needs and linking monitoring to commercial fisheries interests.

The study tests if field preparation methods in agricultural floodplains affect survival and growth of juvenile Chinook salmon, finding no significant differences among treatments.

The paper tracks juvenile Atlantic Sturgeon near a dredge and finds no evidence of detrimental impact on survival or movement.

The paper demonstrates that medaka fish eggs can attach to waterbirds and travel passively, providing empirical evidence for ectozoochory in freshwater fish.

This review examines dispersal and gene flow in anadromous salmonids, finding higher dispersal rates in hatchery fish and variability across species and methodologies.

This study compares spatial ecology and population dynamics of brown trout in reservoirs with and without fish movement barriers, finding that fish passes improve connectivity but have limited overall effectiveness.

This study examines feeding competition between invasive Amazon sailfin catfish and native rohu, finding that catfish outcompete fingerling rohu, threatening their survival.

This study examines how turbidity and habitat complexity affect foraging behavior in black bullheads, finding they prefer carcass prey in complex habitats and live prey in turbid, simple environments.
