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

Environmental 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

Early development and growth of sterlet (Acipenser ruthenus) in the Czech Republic [PDF]

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2014
Growth rate of sterlet larvae and juveniles during 2008 and 2009 was studied under experimental and farming conditions in the Czech Republic. The embryos hatched when reaching a mean total length (TL) of 9.0 mm. Larvae were fed by living food, with a gradual transition to dry diet.

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

Reviews 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 ...

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

River 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 ...

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

Fisheries 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

Reviews 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 ...

Development of DNA identification for sturgeon species with the use of real time polymerase chain reaction

Ribogospodarsʹka Nauka Ukraïni, 2017
Purpose. Sturgeon is the common name for the 27 species of fish belonging to the family Acipenseridae. The family is grouped into four genera: Acipenser, Huso, Scaphirhynchus and Pseudoscaphirhynchus. Four species may now be extinct.

The Research Advances in Distant Hybridization and Gynogenesis in Fish

Reviews in Aquaculture, Volume 17, Issue 1, January 2025.
ABSTRACT Distant hybridization and gynogenesis are two prevalent breeding techniques for fishes. Drawing from the research achievements of our team and the existing literature, we summarize the reproductive traits and genetic features of fishes derived from distant hybridizations and gynogenesis, and we deduce the fundamental mechanisms of these two ...

Genome Manipulation Advances in Selected Aquaculture Organisms

Reviews in Aquaculture, Volume 17, Issue 1, January 2025.
ABSTRACT With the rising global demand for seafood and the challenges posed by overfishing and climate change, the aquaculture sector has become increasingly important in providing high‐quality protein for human consumption. Although traditional selection breeding programs have made great strides in genetic improvement of aquaculture species over the ...
