Simple Field Storage of Fish Samples for Measurement of DNA Content by Flow Cytometry
Cytometry Part A, Volume 99, Issue 7, Page 743-752, July 2021., 2021 Abstract Flow cytometry is an effective and widely used tool for determination of ploidy in fish, but it is not always possible to access the fresh samples for analysis. We investigated the potential for extended storage of fish tissue with sterlet and tench as representative species of Chondrostei and Teleostei, using blood and fin of subadult/adult ...

Trends in aquaculture and conservation of sturgeons: a review of molecular and cytogenetic tools
Reviews in Aquaculture, Volume 13, Issue 1, Page 119-137, January 2021., 2021 Abstract Sturgeons are the most primitive, endangered groups of vertebrates on the planet and often referred to as ‘living fossils’. Their natural populations are decreasing due to habitat destruction, blockage of spawning migration, pollution and overexploitation for their expensive black caviar and boneless meat.
