Morphological characters of artificially induced hybrids of Siberian sturgeon, Acipenser baerii baerii Brandt, and green sturgeon, Acipenser medirostris Ayres

Archives of Polish Fisheries, 2011
The morphometric characters of artificially induced hybrids of Siberian sturgeon, Acipenser baerii baerii Brandt, with green sturgeon, Acipenser medirostris Ayres, were examined until the fish achieved sexual maturity. The measurements encompassed 29 measurable and six meristic characters. Throughout the studied period of fish development, the greatest

Take my breath away: Defining the oxygen saturation threshold for fish cortisol stress response

Journal of Fish Biology, Volume 109, Issue 3, Page 1760-1770, September 2026.
Abstract Human activities are affecting the number, size and severity of hypoxic zones in aquatic ecosystems. As oxygen is one of the most important abiotic factors affecting fish biology, exposure to low levels of dissolved oxygen may lead to a reduction in fitness.

Fish Sperm Subpopulations Detection, Separation, and Application: Current State and Trends

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Modern advances in sperm biology highlight the necessity of recognising intra‐ejaculate heterogeneity as a central concept for advancing both the fundamental understanding of fertilisation processes and the development of artificial reproduction techniques in fishes. ABSTRACT Sperm subpopulations represent a fundamental manifestation of intra‐ejaculate

Effect of crowding stress on growth performance, the antioxidant system and humoral immunity in hybrid sturgeon

Aquaculture Reports, 2023
To evaluate effects of crowding stress on the physiological mechanisms of juvenile hybrid sturgeon (♀Acipenser baerii×♂Acipenser schrenckii, 23 ± 1 g body weight), an experiment was assigned to three initial stocking densities in flowing water ponds (LD =
