Schematic of techniques used to study different aspects of the biology of sturgeons.

*Microchemistry techniques, while not currently applied on a broad level to study population structure and identification, are building in popularity and applicability and may well rank alongside genetic and electronic.
tagging in the near future.
Research techniques are ranked 1–4 in order of use/utility by sturgeon researchers, with a rank of 1 being highest in terms of applicability. Techniques assigned the same number are of equal utility.
