Determining karyotype of sturgeons

open access: yes, 1995
Karyotype of sturgeons Huso huso, Acipenser stellatus, and Acipenser persicus from southern region of- the Caspian Sea, has been examined by use of blood tissue culture. By counting fifty completely extended metaphase plates, the number of chromosomes in Huso huso, and Acipenser stellatus, were determined to be 2n=115±1, NF=356, and 2n=114±1, NF=372 ...

Comparative Diets of Invasive Blue Catfish: Differences Across Rivers and Ontogenetic Stages

open access: yesEcology of Freshwater Fish, Volume 34, Issue 2, April 2025.
ABSTRACT Blue Catfish (Ictalurus furcatus) are an invasive species with expanding populations in freshwater systems, posing significant ecological challenges to native fauna. To assess their potential impacts in diverse aquatic ecosystems, we examined and compared the diets of non‐native Blue Catfish from four rivers in Georgia, USA, two of which drain

Approaching merchant ships elicit behavioral changes in Atlantic sturgeon (Acipenser oxyrinchus) in the St. Lawrence River, Canada

open access: yesJournal of Fish Biology, Volume 106, Issue 4, Page 1047-1057, April 2025.
Abstract There are gaps in our understanding of sturgeon's response to anthropogenic sounds and the spatial scales at which they occur. We measured spatial displacement of Atlantic sturgeon in the St. Lawrence River at various distances of approaching merchant ships.
