Bonev, S., Georgiev, B., Nikolova, L. & Taushanova, P. (2022) Sperm production of Russian sturgeon (A. gueldenstaedtii) raised on an industrial cage farm. Bulg. J. Agri. Sci., 28 (Supplement 1), 172-181 Sturgeons are in unusual conditions when farmed on industrial farms, which can affect their development. In this connection, the qualitative and qu...

Seven-year-old male (n = 25) and female (n = 25) Russian sturgeons (Acipenser gueldenstaedtii), grown under the same conditions on a super-intensive cage farm, 36 plastic and 7 meristic traits are studied and 7 morphometric indices are calculated. Female fish had significantly (P <0.001) better fattening than males, their body was more compact (P <...

A comparative analysis on 36 metric, 7 meristic features was performed and 7 morphometric indices were calculated in seven-year-old male and female hybrids (F1 Acipenser baerii x Acipenser gueldenstaedtii) grown under the same conditions on a super-intensive cage farm. The antiventral (P<0.05) and pecto-ventral (P<0.01) distance are bigger in femal...

The main slaughter and morpho-physiological characteristics of male Siberian × Russian Sturgeon hybrids were studied when grown in an industrial cage farm located in a reservoir in Southeastern Bulgaria. Three groups of different body weight were formed for the purposes of the experiment: 1-2500 to 3499 g; 2-3500-4499 g; 3-4500-5499 g. The studied...

The study clarifies the growth of Siberian Sturgeon, Russian Sturgeon and their hybrid grown on an industrial cage farm. Three groups within each genotype of male individuals with different initial body weight were formed, as follows: Russian Sturgeon - I - 2.504±0.060 kg; II - 3.042±0.063 kg; III - 3.693±0.074 kg; Siberian Sturgeon - I - 1.395±0.0...

A comparative analysis of indicators related to the meat production of a male Sterlet at the age of six and seven summers raised on an industrial cage farm located in Southeastern Bulgaria was performed in the study. The slaughter yield and meat quantities, as well as indices relating to the exterior and interior of the fish, were calculated. Older...

A complex characterization of the physicochemical parameters of the water was performed in a sturgeon cage farm located in a dam in Southeastern Bulgaria during the different stages of the vegetation period. Water monitoring included key indicators for fish farming: temperature, dissolved oxygen, oxygen saturation, electrical conductivity, total ha...

Istraživanje je sprovedeno na jatu trogodišnje sibirske jesetre (Acipenser baerii). Jednogodišnja riba gajena je na farmi sa kaveznim sistemom za vrlo intenzivnu proizvodnju u veštačkom jezeru sa toplom vodom, koje se nalazi u Južnoj Bogarskoj. Utvrđeno je da u ovim uslovima gajenja razvoj gonada sibirske jesetre omogućava razdvajanje po polu u uzr...

The study was conducted in a super intensive sturgeon cage farm located in a warm water reservoir in southern Bulgaria. In the study period (April- December incl.) the average water temperature (TW) ranged from 10.6 to 26°С, dissolved oxygen (DO) from 4.67 to 9.86 mg.dm-3 and dissolved oxygen saturation (DOS) from 53.6% to 90.6%. The period with op...

The aim of this study was to explore the technological properties (sensory properties, colour characteristics, pH and water holding capacity) of Russian sturgeon at age of fi ve and seven years, its hybrid with Siberian sturgeon at age of fi ve, six and seven years and fi ve-year-old Sterlet. The highest sensory evaluated scores for taste and fl av...

Bonev, St., & Nikolova, L. (2019). Development of female Russian sturgeon (Acipenser gueldenstaedtii) and hybrid (Acipenser baerii х Acipenser gueldenstaedtii) gonads reared in net cages. The study was conducted with female individuals of Russian Sturgeon at the age of fi ve and seven years old and hybrid of Sibe-rian and Russian Sturgeon at the sa...

A study was carried out on morpho-physiological characteristics of male six-and eight-summer-old Russian sturgeon (Acipenser gueldenstaedtii) reared in a net-cage farm located in a warm water dam. The fish were fed with commercial granulated sturgeon feed. It was established that the age increase resulted in: statistically significant increase of t...
