Eleven triand tetra-meric motif microsatellite loci were identified in a lake sturgeon genomic library and were tested against the six North American species of Acipenser (lake sturgeon, A. fulvescens; shortnose sturgeon, A. brevirostrum; white sturgeon, A. transmontanus; green sturgeon, A. medirostris; Atlantic sturgeon, A. oxyrhynchus oxyrhynchus; gulf sturgeon, A. o. desotoi) and the two spe...

persian sturgeon, acipenser persicus is a native, commercially important and highly steemed fish species in the caspian sea. in this study, effects of nodularin (nodln), a cyclic pentapeptide hepatotoxin, on liver and gill tissues of a. persicus were studied. nodularin was produced in high amounts by nodularia spumigena, a cyanobacterium species during the algal bloom in the caspian sea and was...

we estimated the genetic diversity and population structure of persian sturgeon across six regions of caspian sea along the coast of iran using eight dna microsatellite loci. full genotypes were obtained for 195 individuals of persian sturgeon. significant differences were detected between a. persicus specimens collected from sefidrud river (p≤0.0001) and those collected from the southern fishe...

Environmental DNA (eDNA) is an emerging sampling method that has been used successfully for detection of rare aquatic species. The Identification of sampling tools that are less stressful for target organisms has become increasingly important for rare and endangered species. A decline in abundance of the Southern Distinct Population Segment (DPS) of North American Green Sturgeon located in Cali...

Efforts have been proposed worldwide to restore sturgeon populations through the use of hatcheries to supplement natural reproduction and to reintroduce sturgeon where they have become extinct. We examined the population structure and inferred the extent of homing in the anadromous Gulf of Mexico (Gulf) sturgeon (Acipenser oxyrinchus desotoi). Restriction fragment length polymorphism and contro...

Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus) experienced severe declines due to habitat destruction and overfishing beginning in the late 19(th) century. Subsequent to the boom and bust period of exploitation, there has been minimal fishing pressure and improving habitats. However, lack of recovery led to the 2012 listing of Atlantic sturgeon under the Endangered Species Act. Although ha...

In this study, random sampling conducted and 90 individuals of Persian sturgeon having 3-5g weight, collected by trawling in 3 earthen ponds and 15 individuals having 10-20g weight, collected by small net in 3 fiberglass Vans. After recording of biometrical characteristics, the intestine and rearing water were cultured on TSA medium. Gram staining and complementary tests were conducted. In orde...
