Genetic protocol of Atlantic sturgeon Acipenser oxyrinchus (L.) fry for restocking the Vistula river, Poland
In Poland the conservation program of Atlantic sturgeon Acipenser oxyrinchus is conducted during over 10 years by Inland Fisheries Institute in Olsztyn, Poland. Material of A. oxyrinchus is annually transported from Canada to Poland and the broodstock of this species is created. Part of imported fish material is breed and released into local rivers e.g. Drweca River, Vistula River. All the impo...
متن کاملExpression Patterns of Atlantic Sturgeon (Acipenser oxyrinchus) During Embryonic Development
During teleost ontogeny the larval and embryonic stages are key stages, since failure during this period of tissue differentiation may cause malformations, developmental delays, poor growth, and massive mortalities. Despite the rapid advances in sequencing technologies, the molecular backgrounds of the development of economically important but endangered fish species like the Atlantic sturgeon ...

متن کاملChanges in age composition and growth characteristics of Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus) over 400 years.
Populations of sturgeon (Acipenseridae) have experienced global declines, and in some cases extirpation, during the past century. In the current era of climate change and over-harvesting of fishery resources, climate models, based on uncertain boundary conditions, are being used to predict future effects on the Earth's biota. A collection of approximately 400-year-old Atlantic sturgeon spines f...
متن کاملExperimental and field evidence of behavioural habitat selection by juvenile Atlantic Acipenser oxyrinchus oxyrinchus and shortnose Acipenser brevirostrum sturgeons.
The present work reports behavioural responses by young-of-the-year (21-30 cm) Atlantic sturgeon Acipenser oxyrinchus oxyrinchus and shortnose sturgeon Acipenser brevirostrum to nine binary combinations of dissolved oxygen saturation (40, 70 and 100%), temperature (12, 20 and 28°C) and salinity (1, 8 and 15). Both species showed no acclimation effects and similar discrimination and avoidance re...
