“…Из-за высокого уровня восприимчивости культивируемых видов гидробионтов к болезням, ухудшения качества воды и широкого спектра стрес-совых состояний (от ферментативной недостаточности до инфекций и освоения новых условий обитания), индустрия аквакультуры испытывает постоянное ограничение в развитии, что в разы увеличивает важность разработки новых отечественных лечебно-профилактических препаратов со свойствами адаптогенов. Для решения этой проблемы активно исследуются не только морфометрические, но и физиолого-биохимические характеристики культивируемых рыб, которые на сегодняшний день остаются все еще малоизученными [11,12].…”

Increasing the output of aquaculture products is an important condition for supporting food security in Russia and ensuring the socio-economic development of the regions. One of the key factors for the sustainable functioning of trout farms is the timely and effective prevention of the occurrence and spread of diseases in farmed fish [8,10]. The purpose of the presented study was to monitor the condition of rainbow trout based on the assessment of biochemical and morphological blood parameters in age dynamics to identify critical periods and develop an adaptogen from green microalgae for the correction of metabolic processes. In the presented study, the hematological status of rainbow trout was studied in the conditions of the fisheries of the Republic of Karelia. The study was conducted in the summer in 4 age groups. During the research, it was revealed that the age of trout significantly affects the biochemical blood levels studied. As a result of the research, it was revealed that in the studied animals with age there is a significant increase in such biochemical parameters as ALT, Total protein, albumin, and urea. Thus, during the monitoring of the biochemical status of rainbow trout under aquaculture conditions, it was found that the condition of the fish’s body worsens with age, which is reflected in the biochemical parameters of the blood, such as total protein, albumin, and urea. In this case, green microalgae Chlorella can act as a natural adaptogen that normalizes blood biochemical parameters due to the high content of available carotenoids. It has been established that the pigments chlorophyll a (6.68 mg/g) and carotenoids (3.36%) accumulate in noticeable quantities in the biomass of.
