Theoretical Estimate of Energy Balance and Nutritional Needs of the Population of Russian Sturgeon Acipenser gueldenstaedtii in the Caspian Sea

Croatian Journal of Fisheries, 2019
Individual and group annual rations of Russian sturgeon Acipenser gueldenstaedtii are calculated on the basis of models describing the energy balance and dynamics of the number of fish generations with natural mortality depending on age. The structure of

The Effect of Feeding with Chironomid and Artemia on Fatty Acids and Amino Acids Profiles in Persian Sturgeon (Acipenser persicus) Larvae

Aquaculture Nutrition, Volume 2024, Issue 1, 2024.
This study aimed to examine the effect of various live foods on the fatty acids (FAs) and amino acids (AAs) profiles in Persian sturgeon (Acipenser persicus) larvae. One thousand and two hundred larvae were cultured in circular concrete tanks, and four treatments were administered as: (1) Artemia + Daphnia, (2) Artemia, (3) Artemia + Chironomid, and (4)

Modeling for Scenarios for Stock Recovery of Russian Sturgeon Acipenser gueldenstaedtii in the Sea of Azov in the Absence of Natural Reproduction

, 2022
— A new model describing the dynamics of sturgeon (Acipenseridae) population unable to recover or ranked as depleted is proposed as a depleted artificially-stocking population (DAP) model.

Growth Performance and Food Conversion Efficiency of Juvenile Russian Sturgeon at Different Feeding Frequencies

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca. Animal Science and Biotechnologies, 2017
The effects of different feeding frequencies (one, two, three and four meals per day) on growth performance and feed conversion efficiency of Russian sturgeon juveniles (Acipenser gueldenstaedtii) was studied over a period of 45 days. The experiment took
