Fish were separated into two groups – with supplementary feeding using trout -1 pellets (FF) and control variant (CF). Specific growth rates in FF and CF were 0.26 and 0.16%.day in length and 0.53 and 0.18%.day-1 in weight, respectively. The average indices of weight condition rose from initial 0.377 and 0.372 to final values of 0.393 and 0.322 in FF and CF, respectively. Fish diet consisted of 25 food items. Chironomid larvae, cladocerans (Daphnia sp.) and detritus prevailed in fish guts with 40.4 – 52.8, 19.1 - 28.8 and 16.3 – 19.4%, respectively. Pelleted feed occurred in 8.7% proportion in one third of examined FF fish. -

Brochure: Sturgeon Identification Guide
Andrey Nekrasov © Photo: STURGEON IDENTIFICATION GUIDE Identification of Sturgeon Species This guide was designed to support the identification of sturgeon species that can be found in the Danube and the Black Sea. It describes seven sturgeon species - one of them an exotic species popular in aquaculture - and three hybrids. The guide also offers detailed features that can be used to differentiate between the species. The primary goal of this guide is to help law enforcement officials identify sturgeon species they may encounter through their work. WHAT IS A STURGEON? Sturgeons and paddlefishes, also referred to scientifically as Acipenseriformes, are a group of ancient fish originating more than 200 million years ago. They migrate mostly in order to spawn and live in freshwater, coastal waters and seas of the Northern Hemisphere. According to the IUCN*, 23 of the 27 species are on the brink of extinction, being thus the most critically endangered group of species on Earth. *International Union for Conservation of Nature Sturgeons have quite unique features: Depending on the species, Five rows of bony scutes: Two nostrils on the snout smaller scutes can also be one row along the back, found in between the rows two along both sides, If a fish has only of the larger scutes, behind and two on the belly one nostril, it is the dorsal fin and along the most likely from anal fin, which can be a very aquaculture. important characteristic for differentiation.

Conservation and Sustainable Use of Wild Sturgeon Populations of the NW Black Sea and Lower Danube River in Romania
Conservation and sustainable use of wild sturgeon populations of the NW Black Sea and Lower Danube River in Romania Raluca Elena Rogin Marine Coastal Development Submission date: June 2011 Supervisor: Egil Sakshaug, IBI Norwegian University of Science and Technology Department of Biology Abstract Sturgeons belong to one of the oldest families of bony fish in existence, having their first appearance in the fossil records approximately 200 million years ago. Their natural habitats are found in the subtropical, temperate and sub-Arctic rivers, lakes and coastlines of Eurasia and North America. In the Romanian waters, five anadromous species of sturgeon, out of the total 25 species known by science, once migrated from the Black Sea into the Danube for spawning: beluga; Huso huso , Russian sturgeon; Acipenser gueldenstaedtii , stellate sturgeon; A. stellatus , ship sturgeon; A. nudiventris and the European Atlantic sturgeon; A. sturio (Knight, 2009). The NW Black Sea and Lower Danube River sturgeons, like many Acipenserids, were seriously affected by the rapid changes brought by human development. Being one of the finest caviar producers in the world they were intensively harvested for many centuries. Heavy uncontrolled fishing and destruction of habitat led to the collapse of most of the Acipenserids and the total disappearance of the European Atlantic sturgeon (A. sturio ) from the NW Black Sea. Worldwide public attention was focused on sturgeon conservation after their listing in the IUCN Red List of Threatened species in 1996. In 1998, after evaluating their abundance in the wild, CITES also decided to strictly regulate the international trade in all Acipenserids. The paper aims to analyze and review conservation measures that were taken locally, nationally and internationally by humans and the effect they had on one of Europe’s only naturally reproducing sturgeon populations. -

The Siberian sturgeon, Acipenser baerii Brandt, is were reflected in several reports of Siberian sturgeon reported in the Reda River, which flows into the Puck Bay, for in internal Polish marine waters and its territorial the first time. In total, 12 specimens of A. baerii were caught sea. Most reports from Polish Marine Areas were during monthly surveys in June and July 2006. The fish were from the Szczecin Lagoon to the Pomeranian Bay captured during downstream movement between 18:00 and 06:00. The specimens collected in Reda River ranged from (Gessner et al. 1999, Arndt et al. 2000). According to 10.3 to 15.5 cm standard length (SL). It is hypothesized that Kolman (2000), there have not been any reports of A. the fish originated from one of the hatcheries located on the baerii in Polish rivers, although a few earlier reports banks of the Reda River.

Acipenser Baerii Brandt, 1869 Siberian Sturgeon Esturgeon Sibérien
Doc. AC.16.7.2 Annex Acipenser baerii Brandt, 1869 Siberian Sturgeon Esturgeon sibérien Order: ACIPENSERIFORMES Family: ACIPENSERIDAE SUMMARY Siberian Sturgeon (Acipenser baerii) may live for up to sixty years and generally reach sexual maturity between 18 and 28 years of age, except in the Lena River where fish mature sexually around 9-12 years of age. The maximum weight recorded is 210 kg, but A. baerii usually weigh approximately 65 kg. Little information is available on the current population status for this species in China and Kazakhstan. However, the limited data available for the Russian Federation show that the spawning area has declined by up to 40% in some areas due to dam construction and increased abnormal oogenesis has been observed, probably due to chemical and nuclear water pollution. The population in China is low and economically insignificant. Catch volumes in the Russian Federation have generally declined, probably as a result of the above listed anthropogenic disturbances as well as over-fishing. However, the Russian Federation is the only country where significant levels of catches have been reported. The annual catch of A. baerii in the Ob’-Irtysh River basin decreased from 1,410 tonnes (t) in the 1930s to 11 t in 1997. Annual catches in the two other major Siberian rivers in the late 1990s were 16 t per year in the Yenisey River and 13-20 t per year in the Lena River. The Lena population of A. baerii is most commonly bred in captivity, because it completes its life cycle in freshwater and sexually matures relatively early. -

Sterlet (Acipenser ruthenus) Ecological Risk Screening Summary U.S. Fish and Wildlife Service, Web Version - 9/5/2017 Photo: J. Bukovský. Licensed under CC BY-NC. Available: http://eol.org/data_objects/2005171. 1 Native Range and Status in the United States Native Range From Gesner et al. (2010): “This species is known from rivers draining to Black, Azov and Caspian Seas; Siberia from Ob eastward to Yenisei drainages. Its current strong holds are the Volga, Ural and Danube systems.” From CITES (2000): “It originally inhabited the rivers of Eurasia, being widely distributed in rivers flowing into the Caspian, Black, Baltic, White, Barents and Kara Seas and the Sea of Azov.” Status in the United States No reliable records of Acipenser ruthenus in the United States were found. A record of Acipenser ruthenus for a location near Baltimore, Maryland was found (GBIF 2013). No other records indicate any Acipenser ruthenus within the United States. The record dates 1 from 1888 and cannot be determined if it is the result of a voucher specimen with the Smithsonian Institution or a misidentification. Means of Introductions in the United States No records of Acipenser ruthenus in the United States were found. Remarks Witkowski and Grabowska (2012) and CITIES (2000) state that Acipenser ruthenus may be able to hybridize with other Acipenser species and with Mississippi Paddlefish Polyodon spathula. 2 Biology and Ecology Taxonomic Hierarchy and Taxonomic Standing From Eschmeyer et al.
