Abstract

The inclusion of all species of sturgeon in commercial restrictions under the Convention for International Trading of Endangered Species (CITES) and the red list of the International Union for the Conservation of Nature (IUCN) has made their conservation an inevitable priority. Diseases are considered as the main factor limiting the development of sturgeon. Although the characteristic of andromes of sturgeon has made them more resistant to certain diseases in nature compared to other fish species, the constant interaction of sturgeons with their surroundings makes them susceptible to potential pathogens. The immunity of this precious species is relevant for basic evolutionary and applied research, including protection of wild sturgeons, caviar, and meat-producing aquaculture, and their re-introduction through conservation aquaculture. The expansion of global aquaculture itself is recognized as a factor in the spread of new pathogens with the potential to threaten both farmed and wild fish populations. The disadvantage of intensification of the aquaculture operations has been primarily due to diseases, especially during the early stages of production. Hence, well-balanced immunity is pivotal for maintaining sturgeon health. The immune system in fish is a combinational system including innate and adaptive immunity. Bright evidence is presented for the effectiveness of vaccination against pathogens of fish under aquaculture conditions. Results proposed that stimulation of cellular immunity by DNA vaccines leads to improvement in protective immune responses due to better mimicking of infection compared to conventional inactivated vaccines.
