Comparative study of the growth performance and gonadosomatic index of Beluga (Huso huso) and Persian sturgeon (Acipenser persicus)

Authors

Abstract:

In this study, growth performance, gonadosomatic index (GSI), and gonadal histology of beluga (Huso huso) and Persian sturgeon (Acipenser persicus) were investigated for 12 months. Sixty individuals of fifteen-month old beluga and Persian sturgeon with body mean weight of 781±55 g and 469.5±38 g, respectively, were distributed in the concrete tanks (5×1×1 m) with water capacity of 2.5 m3 in triplicate. At the end of the experimental period, total weight of beluga and Persian sturgeon were 3518.11 and 1561.23 g, respectively, and weight gains were 2737.11 and 1091.73 g, respectively. The differences of SGR values between two species were significant only in the first six-month period; the SGR values of beluga in the first and second three-month period, , 0.64% and 0.49%, respectively, were significantly higher than of Persian sturgeon, 0.50% and 0.33%, respectively at the same period. The FCR value of beluga (1.43) was significantly lower than of Persian sturgeon (1.69). The gonadosomatic index (GSI) values of Persian sturgeon were significantly higher than of beluga, as at the end of the study period, the values in the beluga and Persian sturgeon were 1.39% and 0.38%, respectively. Number of primordial oocytes was increased significantly in the females of both species and tubules in the beluga testis were observable, whereas developed in the Persian sturgeon testis at the end of experimental period. In conclusion, growth performance of beluga was higher than of Persian sturgeon, while gonadal development in Persian sturgeon was more than in beluga.

Morphological and Histological Study of Kidney in Juvenile Great Sturgeon (Huso huso) and Persian Sturgeon (Acipenser persicus)

Sturgeons are ancient and commercial fishes which posses’ primitive characteristics and due to their great inflections are able to live in both freshwater and marine environments. So their kidney has great ability for adaptation process. In order to find the structure and distribution of kidney nephrons in juvenile Huso huso and Acipensr persicus, sampling of head, body and caudal parts of kidn...

Isolation and characterization of Lactobacillus species from intestinal contents of beluga (Huso huso) and Persian sturgeon (Acipenser persicus)

Lactic acid bacteria are characterized as gram-positive, usually non-motile, non-sporulating bacteria that produce lactic acid as a major or sole product of their fermentative metabolism. In this study, the presence of lactobacilli were investigated in the intestines of beluga ( Huso huso) and Persian sturgeon ( Acipenser persicus ), inhabiting Caspian sea. The obtained data showed that various...

The combined effects of photoperiod and feeding time on growth performance of beluga sturgeon (Huso huso)

This study aimed to evaluate the effect of photoperiod and different feeding times on growth performance and feed efficiency of juvenile beluga sturgeon (Huso huso) for 56 days. One hundred and twenty fish with an average weight of 51.5 ± 0.4 g (mean ± SD) subjected to four different treatments with three replications which distributed in 12 circular concrete tanks under the treatments includin...

Semen obtained from four Beluga males (Huso huso) was cryopreserved using extender; Tris-sucroseKCl (30mM Tris, 23.4mM sucrose, 0.25mM KCl, PH 8.0) supplemented with MeOH at concentration of 5%, 10% and 20%. Semen was diluted, respectively, with ratios of 1:0.5, 1:1 and 1:2 with extender and frozen in liquid nitrogen vapor.Frozen sperms after 30 and 60 days were excluded from freezing. Experime...

Effect of freezing rate on motility, adenosine triphosphate content and fertilizability in beluga sturgeon (Huso huso) spermatozoa.

Broodstock selection programs are currently underway for sturgeon species. To complement and further these selection programs we need to develop sperm cryopreservation procedures. In the present study, we describe the effects of freezing rate (-10°C, -15°C, -20°C, -30°C and -40°C/min) on gamete quality characteristics (i.e., duration of motility (s), motility percentage (%), ATP content (nmol/1...
