A Selection of Sturgeon Species
Aquaculture Improvement Techniques in natural environments have facilitated the Re-Population of the following sturgeon species:-
Huso Huso – Beluga Sturgeon
This is ‘The Celebrated Sturgeon Species’. A wild specimen was caught, measuring well over 9 m and weighing a massive 1400 Kg. This species carries steel blue to grey and black skin markings with light ventral and white creamy bony scutes down its back. Its flesh and its most precious “Beluga Caviar” represent an attractive an undertaking as the actual perpetuation of this rare species.
This Acipenser Transmontanus – White Sturgeon
Being the second largest species in the Acipenser family, this is an ancient, freshwater, bottom dwelling feeding fish and characterised by a long and large cylindrical body, a subconical snout and four Barbels (beard-like) located at the base of its head. Reaching maturity within 10 years, the Transmontanus produces flawless, large sized roe in a solid dark chrome appearance.
Acipenser Gueldenstaedtii – Russian
This is a true representative of the Acipenseriformes family. Aquaculture offsprings are reared to an average of 1.25m and rank second in growth rate and longevity. The rare diamond variety has beautiful star-like markings but they are invariably lost, turning grey-black in colour during adulthood. The Gueldenstaedtii medium sized roes’ bear a delicious buttery and aromatic flavour, featuring ample colouration choices from medium yellow, olive green via hazelnut brown to anthracite.
Acipenser Baerii – Siberian Sturgeon
The Siberian Sturgeon is the most popular and by far the easiest aquaculture species to breed. Resilient and tough, with a healthy and rapid rise to adulthood, this sturgeon will reach a maximum length of 1.2m in clean and comfortable aquaculture surroundings. The skin is brown-grey and black with the underside in contrasts of white. The end of their nose features a white tip. Siberian Sturgeon caviar roes are of a medium size, typified by a deep mahogany-brown colour with a velvety taste.
Acipenser Stellatus – Stellate Sturgeon
Best known as the Stellatus or Stary Sturgeon and easily recognised by its elongated nose and head. This part of its anatomy represents 25% of the total body length. This sturgeon keeps its beautiful markings throughout its life. Reaching a maximum of 1.50 m in the wild but considerably less in an aquaculture environment. All Stellate Sturgeons are keen jumpers. Despite its smaller physical attributes, roe remains small and graceful, appearing in luminous metallic-grey and with a memorable, fresh sea-salt flavour.
Acipenser Ruthenus – Sterlet Sturgeon
The starlet is a slow-growing sturgeon of a very tolerant nature. In captivity it measures 0,60 – 0,90 m, reaching maturity over a period of ten years. Distinctive features are white edge markings with lines along its back to the pectoral and front fins. The small and light blue-greyish roes set it apart from the Stellatus.
