Simulated trapping and trawling exert similar selection on fish morphology
Sign Up to like & getrecommendations! Published in 2022 at "Ecology and Evolution"
DOI: 10.1002/ece3.8596
Abstract: Abstract Commercial fishery harvest can influence the evolution of wild fish populations. Our knowledge of selection on morphology is however limited, with most previous studies focusing on body size, age, and maturation. Within species, variation… read more here.

DOI: 10.1002/rra.4039
Abstract: Dam construction and streamflow regulation are increasing throughout the world, with impacts in impounded aquatic ecosystems. Hydropower dams, some of them causing a phenomenon called “hydropeaking” during their operation, are known for having a variety… read more here.

DOI: 10.1007/s10661-020-08580-z
Abstract: Many environmental monitoring programs include an assessment of the health of fish populations using a sentinel species and include an indicator of reproductive potential. Knowledge of the reproductive strategy of the fish species is critical… read more here.

Are fish in danger? A review of environmental effects of marine renewable energy on fishes
Sign Up to like & getrecommendations! Published in 2021 at "Biological Conservation"
DOI: 10.1016/j.biocon.2021.109297
Abstract: Abstract Many fish species are threatened worldwide by overfishing, contamination, coastal development, climate change, and other anthropogenic activities. Marine renewable energy (MRE) is under development as a sustainable alternative to carbon-based energy sources. Regulators and… read more here.

Habitat fragmentation caused by contaminants: Atrazine as a chemical barrier isolating fish populations.

DOI: 10.1016/j.chemosphere.2017.11.014
Abstract: Information on how atrazine can affect the spatial distribution of organisms is non-existent. As this effect has been observed for some other contaminants, we hypothesized that atrazine-containing leachates/discharges could trigger spatial avoidance by the fish… read more here.

DOI: 10.1016/j.fishres.2018.06.019
Abstract: Abstract Stratified random sampling (StRS) can lead to improved precision and accuracy in estimating key fisheries population parameters, particularly when the spatial distributions of target fish populations have high heterogeneity among different strata and homogeneities… read more here.

Interannual temperature variability is a principal driver of low-frequency fluctuations in marine fish populations
Sign Up to like & getrecommendations! Published in 2022 at "Communications Biology"
DOI: 10.1038/s42003-021-02960-y
Abstract: Marine fish populations commonly exhibit low-frequency fluctuations in biomass that can cause catch volatility and thus endanger the food and economic security of dependent coastal societies. Such variability has been linked to fishing intensity, demographic… read more here.
