Effects of different rearing temperatures on muscle development and stress response in the early larval stages of Acipenser baerii
The present study aims at investigating muscle development and stress response in early stages of Siberian sturgeon when subjected to different rearing temperatures, by analysing growth and development of the muscle and by assessing the stress response of yolk-sac larvae. Siberian sturgeon larvae were reared at 16°C, 19°C and 22°C until the yolk-sac was completely absorbed. Sampling timepoints ...
متن کاملEffect of different stocking densities on hematological parameters and growth performance of great sturgeon (Huso huso)
A 5 weeks study was conducted to determine the effects of different stocking density on hematological parameters of great sturgeon. Fish were cultured in duplicates of fiberglass tanks under stocking densities of 50, 75, 100 and 125 fish/m3 as T1, T2, T3 and T4 respectively. Based on the results significant increase (p<0.05) in total body weight and total length were related to low density grou...
متن کاملExpression of growth hormone gene during early development of Siberian sturgeon (Acipenser baerii)
The mRNA expression of growth hormone (GH) gene in early development stages of Siberian sturgeon was investigated using RT-PCR method. Samples were collected from unfertilized eggs up to 50 days post hatched (dph) larvae in 11 different times. Ribosomal protein L6 (RPL6) transcripts were used as the internal standard during quantification of GH mRNA expression. The results showed that the GH mR...
متن کاملEvolutionary relations and population differentiation of Acipenser gueldenstaedtii Brandt, Acipenser persicus Borodin, and Acipenser baerii Brandt
Russian ( Acipenser gueldenstaedtii), Persian ( A. persicus) and Siberian ( A. baerii) sturgeons are closely related 'Ponto-Caspian' species. Investigation of their population structure is an important problem, the solution of which determines measures for conservation of these species. According to previous studies, 'baerii-like' mitotypes were found in the Caspian Sea among 35% of Russian stu...
