Abstract

Experimental-production studies effects of keeping in table salt solutions producers and juveniles of valuable fish species: Russian and stellate sturgeon, rainbow trout, catfish and roach were carried out in order to develop a new effective method of their cultivation in fully controlled environmental conditions. The results were evaluated according to fish-breeding-biological and physiological indicators − haemoglobin content, total protein, osmolality of blood serum, cavity fluid and urine. To assess the degree of stress, a cytomorphometric analysis of the hypothalamic-hyperphysical neurosecretory system state was carried out using light and electron microscopy methods. The enhance effects of fish survival, breeder’s reproductive quality, young’s growth rates were first established in \"critical\" salinity 4-8‰ medium. On breeders originally it was shown the possibility to change sea water on the table salt solution of the same concentration. With such a low concentration of salt a new bio stimulating effect of this artificial medium on the fish body was installed, due to the absence of its well-known toxicity. The highest degree of survival and delayed sex maturation of roach and stellate sturgeon were specifically installed in the same concentration of industrial salt solutions. The possibility of changing the sea water to industrial salt solution 5-7‰, allowed to developed \"A method to reserve fish breeders\", which however is not applied to the young fish cultivation. So the next stage in the development of this method was tested it already on juvenile fish to determine the possibility of its effective cultivation in this artificial bio stimulating medium. The results of the search experience on trout fingerlings showed the increased survival and growth in salt solutions, especially in 12‰ as compared to control. The first experimental verification of this method on the clarias catfish Citation: Ragni Kumari, Luxmi Singh (2025) Low Vision Management in a Case of Stargardt\'s Disease. On J Clin & Med Case Rep 1(2): 1-5. 2 fingerlings in the recycling aqua cultural system (RAS) showed the largest growth rates in 5‰ salt solution in full its survival in all variants. Fish received data and analysis bio stimulated effects impact on the body\'s critical salinity gives the opportunity to develop a fundamentally new way of cultivation of valuable fish species in an artificial bio stimulated habitat. This technique can allow manage quality of producers, obtaining offspring and the cultivation of young fish. It is aimed at improving the efficiency of breeding fish in aquaculture due to the availability of the application for any type of fish farms with the effects of increasing survival rate and young growth rate. It is expected that the change of the sea water on the cheap solution of table salt can be widely practiced at fish plants in various fields and at all stages of fish biotechnology works, especially RAS
