Food availability influences angling vulnerability in muskellunge

open access: yesFisheries Management and Ecology, Volume 31, Issue 1, February 2024.
Abstract Reduced food availability increases the capture of several fish species, although the mechanisms responsible for how food resources result in increased capture are undefined. Our objective was to quantify the mechanism by which food availability might influence the angling vulnerability of muskellunge (Esox masquinongy).

The Effects of Different Levels of Potassium Diformate and Calcium Diformate on Growth, Digestion Enzyme Activity, Antioxidant Capacity, Intestinal Flora, Stress Markers, and Some Serum Biochemical Analytes in Juvenile Beluga Huso huso

open access: yesAquaculture Research, Volume 2024, Issue 1, 2024.
Potassium diformate (KDF) and calcium diformate (CaDF) are organic acids that modulate growth performance, stress, and biochemical status. So, the present study aimed to investigate the effects of different levels of potassium diformate and calcium diformate on growth performance, stress markers, oxidant/antioxidant status, microbial flora, and some ...

Identification of metallothionein gene structure in sterlet (Acipenser ruthenus)

open access: yes, 2017
Aquatic organisms present, not only simple sources of accumulated metal, but can interact with metals, altering their toxicity. Due to exposition of biosphere with metals, organisms have developed various defense mechanisms to protect themselves against adverse effects of these ions and their compounds.
