| Freshwater Crayfish is one of the most valuable and economic fisheries of West Azarbaijan Province, Iran. But unfortunately, with the reduction of reserves since 2014 and the implementation of the fishing ban plan since 2017, the yield from Aras Reservoir Dam is still zero. In this regard, the reproduction and artificial breeding of crayfish with the aim of restoring the reserves and developing native species from the native genetic reserves of the country is important. Therefore, it is essential to know more about the physiology of crayfish, especially the function of the immune system and resistance to stress and disease. Immunity of freshwater crayfish has received much attention due to the urgent need for its conservation. Today, the understanding of the cellular and humoral defense systems of the freshwater crayfish has increased, although the regulatory mechanisms involved in these processes need to be updated.The present study includes an overview of the immunity of freshwater crayfish, including a classification system of hemocyte subtypes, molecular factors involved in hematopoiesis, and the role of hemocyte subpopulations in cellular responses, including hemocyte infiltration, inflammation, encapsulation, and Extracellular Trap cell death pathway (ETosis), as well as the identity and function of hyaline cells, the production of neoplasia, and the emerging topic of the role of sessile hemocytes in peripheral immunity. Stressful conditions increase maternal care and delay the growth and development of juvenile crayfish. Serotonin, but not dopamine, controls stress response and anxiety-like behavior in the freshwater crayfish. To produce a breed of crayfish with the desired phenotype of disease resistance and fast growth, it is possible to improve the disease resistance traits of the parents through phenotypic selection and crossing to produce stress and disease resistant generation to reduce mortality and increase production as well as increasing the time and distance of transportation. |
