چکیده

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 imported material is obligatory genetically analyzed. the analysis must include the species verification and the genetic diversity of fish. such analyses are necessary to issue a permit for restocking the local rivers. this paper presents a genetic characteristics of juvenile atlantic sturgeon imported from canada by fish farm komorowo, poland intended for restocking the river vistula. genetic analysis of the 45 juvenile atlantic sturgeon was conducted using five microsatellite dna markers (spl-106, spl-101, atr-113, aox-23a, aox-23b) and one fragment (240 base pairs) encoding the cytochrome b gene (cytb). in the present paper the genetic information about optimal genetic diversity and good condition of restocked materials of atlantic sturgeon were described.

Expression 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 ...

Using circulating reproductive hormones for sex determination of Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus) in the Saco River estuary, Maine

The Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus) is a long-lived, anadromous fish species ranging from Labrador, CA to Florida, USA. In the Saco River, located in the Gulf of Maine, this species was not present during a survey study ending in 1982, but was found inhabiting the estuary in 2007. Although the reason for the return of this sturgeon to this river system remains unknown, resea...

Changes 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...

Current Occurrence of the Atlantic Sturgeon Acipenser oxyrinchus in Northern Spain: A New Prospect for Sturgeon Conservation in Western Europe.

Acipenser oxyrinchus is considered extirpated in Europe, but numerous breeding populations still exist on the Atlantic coast of North America. An adult female A. oxyrinchus, 2500 mm total length and 120 kg wet weight, was accidentally fished on 24 November 2010 near the coast of Gijón, Asturias, Spain. The fish was identified by its morphological pattern as well as by mitochondrial and nuclear ...

Genetic mixed-stock analysis of Atlantic sturgeon Acipenser oxyrinchus oxyrinchus in a heavily exploited marine habitat indicates the need for routine genetic monitoring.

Although a previous genetic mixed-stock analysis (gMSA) conducted in the early 1990s showed that marine-captured New York Bight Atlantic sturgeon Acipenser oxyrinchus oxyrinchus almost exclusively originated from the Hudson River, fish from southern U.S. rivers were well represented within this contemporary sample (n = 364 fish), at least during the autumn. Widely distributed spawning stocks ar...
