Tracking Aquatic Biodiversity With Environmental DNA: A Study in Quebec's Mining Region

open access: yesEnvironmental DNA, Volume 7, Issue 5, September–October 2025.
This study assesses the effectiveness of environmental DNA (eDNA) for monitoring fish species in mining‐impacted waters of Quebec's James Bay region. eDNA analyses detected key species, including culturally significant ones, and revealed potential biodiversity impacts, such as reduced detectability of lake sturgeon in areas with habitat disturbance and

Artemia Enrichment Strategies: A Comprehensive Review of Nutritional Enhancements With Emphasis on Fatty Acid Profiles in Aquatic Species

open access: yesReviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT Artemia (brine shrimp) is a foundational live feed in global aquaculture, renowned for its adaptability, ease of production, and favorable nutritional profile. However, in its natural state, Artemia contains suboptimal levels of highly unsaturated fatty acids (HUFAs), particularly docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA ...

Mitochondrial heteroplasmy in an avian hybrid form (Passer italiae: Aves, Passeriformes) [PDF]

open access: yes, 2019
Mitochondrial heteroplasmy is the result from biparental transmission of mitochondrial DNA (mtDNA) to the offspring. In such rare cases, maternal and paternal mtDNA is present in the same individual.

Implications of climate‐change‐induced stressors and water management for sterlet populations in the Middle and Upper River Danube

open access: yesRiver Research and Applications, Volume 41, Issue 2, Page 448-465, February 2025.
Abstract Sturgeons are a group of iconic rheophilic fish whose populations worldwide are currently undergoing significant declines. The study investigates the impact of climate change and anthropogenic activities, particularly the Gabčíkovo barrage system, on the survival and distribution of the sterlet, the last surviving sturgeon species in the ...

Selected coelomic fluid parameters of sterlet, Acipenser ruthenus L.: effects of light color and photoperiod

open access: yesArchives of Polish Fisheries, 2014
Light and color have effect physiological aspects of fish such as growth, the neuro-hormonal system, and reproduction. In the present study, the effects of light color and photoperiod on the levels of selected parameters of coelomic fluid (glucose, total

Effectiveness of mass marking of juvenile sterlet (Acipenser ruthenus) with alizarin red S stain on field detection

open access: yesFisheries Management and Ecology, Volume 32, Issue 1, February 2025.
Abstract Sterlet (Acipenser ruthenus), one of the last sturgeons in the Danube basin, is regularly stocked in national and international restoration programs, but the efficacy of stocking has not yet been evaluated. Effectiveness of stocking should involve marking and evaluating growth and survival of juveniles.

Impacts of Global Warming on Quality of Male Fishes: Evidence From A Meta‐Analysis of Temperature Effects on Sperm Motility Kinematics

open access: yesReviews in Aquaculture, Volume 17, Issue 1, January 2025.
ABSTRACT Studies have demonstrated adverse effects of global warming on aquatic ecosystems. However, the effects of increased water temperature (IWT) on fish reproduction are still doubtful in species spawning at low or high temperatures. In this meta‐analysis, we elucidated the effects of global warming on spermatozoa functions, key determinants of ...
