the application of nanotechnology in drug delivery and a variety of supplements is very impressive. in this regard, the use of this knowledge can be effective in the performance of medicinal plants in aquaculture. in the present study aloe vera was extracted and its nanoparticles were produced. three levels of aloe vera nanoparticles in siberian sturgeon (acipenser baerii) were evaluated for th...

Exposure to chemical contaminants is often invoked to explain recruitment failures to populations of sturgeon worldwide, but there is little empirical evidence to support the idea that young sturgeon are sensitive at environmentally relevant concentrations. The authors used shortnose sturgeon (Acipenser brevirostum) and Atlantic sturgeon (Acipenser oxyrinchus) as models to investigate the sensi...

Acipenser dabryanus is listed as a Critical Endangered species in the IUCN Red List and the first class protected animals in China. Fortunately, A. dabryanus specimens are being successfully bred in captivity for conservation. However, for effective ex situ conservation, we should be aware of the genetic diversity and the degree of relatedness of the individuals selected for breeding. In this s...

Measurements of branchial cavity water pressures and flow patterns, arterial blood PO2 and pH, and oxygen utilization and uptake have been made in undisturbed, free swimming sturgeon, Acipenser transmontanus. Although the jaws are degenerate and the oral apparatus is highly modified for feeding, gill ventilation is nonetheless powered by a buccal force pump and an opercular suction pump common ...
