Serum Biochemical Parameters of Caspian Lamprey, Caspiomyzon wagneri During Final Spawning Migration
نویسندگان
چکیده
Serum biochemical parameters are important aspects in the management of endangered species such as Caspiomyzon wagneri. The objective of this survey was to determine some serum ionic and metabolic parameters and those relationships in 22 migratory population of Caspian lamprey in shirood river (a river located at the south of Caspian sea). There was no significant (P<0.05) difference between level of calcium (8.52 ± 2.9-9.14±0.97 mg/dL), magnesium (2.97±1.04-2.86±0.97 mg/dL), phosphorus (11.23±3.18-13.57±6.61 mg/dL), Iron (0.37±0.19-0.54±0.3 mg/dL), total protein (4.7±2.47-5.81±3.85 g/dL), glucose (93.98±22.89-104.10±32.38 mg/dL) and cholesterol (164.00±59.19-170.99 ±60.77 mg/dL) in male and females. The correlation between magnesium with calcium (P<0.05) and cholesterol (P<0.05) and glucose (P<0.01) was significant. There was a significant correlation between phosphorus and total protein (P<0.05). The correlation between cholesterol with glucose (P<0.01) was significant. But correlation between total protein with magnesium to phosphorus ratio and calcium to phosphorus ratio (P<0.05), was invert. According to influences of ionic and metabolic blood’s serum on regulation of reproduction and growth in Caspian lamprey, can use from these results in management of reproduction and culture of this endangered species and our results can help to more understand lampreys physiology in starvation time compare to other higher vertebrates.

The Caspian lamprey (Caspiomyzon wagneri) is one of the most important ecological and native fish species of the Caspian Sea basin. The present study was conducted to identify the factors affecting the population decline of this species in Shiroud River as one of the important habitats of fish in the southern basin of the Caspian Sea. For this purpose, three stations were selected for sampling ...
متن کاملConcentration of Mercury in Selected Tissues of the Caspian Lamprey (Caspiomyzon wagneri) Migrants in Spawning Season
Background: Mercury (Hg) is considered a global pollutant because Hg0 which is the predominant form of atmospheric Hg resides in the atmosphere for as long as 0.5 to 2 years. Mercury has many negative effects on the reproductive, respiratory, and immune systems. Methods: In this study, 24 Caspian lampreys (Caspiomyzon wagneri) were transported to the university laboratory and then stored in ...

The present study aimed to investigate effects of the heavy metal Cd on the sperm morphological indices of Caspimyzon wagneri. The sperm were exposed to 0.01, 0.1, 1, 10, 100 and 1000 mg.L‑1 Cd for three minutes, three and 36 hours. The sperms exposed to Cd showed an increase in the length, width and surface of the head, flagella degradation and slightly flagella breakage. With increase of Cd ...
