We applied the adaptive management approach to analyze the demand and feasibility of adaptive management of fish stocks in a large regulated lake, Oulujärvi, in northern Finland. The process consisted of four phases: (1) analysis of the current state of the fisheries system (fishers, related markets and industry, fisheries researches and authorities, related organizations, etc.); (2) analysis o...

an eight-week experiment was carried out to determine the effects of dietary pediococcus pentosaceus as probiotic on the body composition and gut microbiota of siberian sturgeon, acipenser baerii . a total of 180 fish with mean body weight of 143±0.01g were randomly distributed into 12 200l fiberglass tanks as four treatments with three replicates, including groups fed with diet containing 2×10...

Diseases have been the bottle-neck to sustainable development of sturgeon cultivation. Bacterial septicemia that caused mass mortalities of sturgeons is still prevalent in Shanxi and Yunnan provinces in China. The epidemiology and pathogenicity of the disease were investigated. Four predominant isolates of bacteria were isolated from Siberian sturgeons (Acipenser baerii) suffering from bacteria...

Worldwide, sturgeons (Acipenseridae) are among the most endangered fishes due to habitat degradation, overfishing, and inherent life history characteristics (long life span, late maturation, and infrequent spawning). As most sturgeons are anadromous, a considerable portion of their life history occurs in estuarine and marine environments where they may encounter unique threats (e.g., intercepti...

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...
