Sturgeon is kind of fish which is liked by people all over the world especially UK. The name Sturgeon is a common name given to over 25 species of fish that belong to a family called as Acipenseridae. This fish has great commercial value and is found in large numbers along the coasts of Pacific as well as Atlantic oceans, the Mediterranean, rivers and inland seas.
Sturgeons are also called as “primitive fishes” because of their unchanged morphological characters since the last available fossil record. Here we are going to discuss about the fish’s biological characteristics, origin, morphology and its utilization.
Most common variety of sturgeon
- The Sterlet is the most common variety of sturgeon because it is a small, freshwater species.
- It grows slowly in a garden pond which makes it a wonderful addition to any pond due to its slow growth and small maximum size (compared to other sturgeon such as beluga, diamond, siberian, stellatus and bester.)
- The scientific name of a sterlet sturgeon is Acipenser Ruthenus.
- The body of a sturgeon is spindle-shaped and elongated. The mouth of this lovely fish is positioned underside of the head and it has big fleshy lips. On certain occasions, you may find sturgeons as big as 12 feet in size and there are few species which grow up to 18 feet in size. Another rare thing about sturgeons is that they live quite long, some species can be seen living well up to 100 years and they attain sexual maturity at the age of 20 and sometime even more.
Sturgeon behavior and uses
- These fishes normally relish on small fish, shells and crustaceans but when harvested commercially they are being given with special fish food such as sinking pellets and high protein fish food. Sturgeons have no teeth and hence, they swallow different items. One of the most unusual things about sturgeons is that they feed non- visually and use a special set of sensors.
- These are used for flesh as well as caviar. In last few years, scientists have developed unique and revolutionary technique which is helping them to take out the caviar without killing the fish. This incredible technique is proving to be a brilliant breakthrough as it is helping this fish from extinction.
There is one more benefit offered by this technique. The surviving sturgeon produces finest quality of caviar each year. As the fish becomes more mature, high quality caviar can be collected. It is a win-win situation for everybody and moreover, when the fish is kept in pristine conditions the quality of the caviar keeps getting better.
Well, now that you are fully aware about this wonderful fish species, it is now time to take care of them and feed them with great and high protein fish food sinking pellets.
