Snook is considered one of the most important fisheries in Mexico due to its cultural and economic importance; nevertheless, the production potential remains to be untapped, as current commercial production is based on wild-catch temporality, distribution and abundance. For these reasons, the objective of this study was to evaluate the biochemicals analysis of the Pacific White Snook Centropomus viridis culture in 10m diameter and 3m deep cages (235m3) and wild organisms. The experiment began in September 2019 when 15,000 organisms of C. viridis with an initial weight of 0.8±0.2g were stocked in one floating cage where they would remain for four months during the nursery stage. During the experiment physicochemical parameters such as dissolved oxygen, temperature, pH and salinity as well as nutrients such as ammonia, nitrites and nitrates were closely monitored, and recorded. Biochemicals variables such as glucose (mg·dL-1), protein (g·dL-1), total lipids (g·dL-1) and cholesterol (mg·dL-1) were evaluated. The results of our performance variables were, Correlation between physical chemical parameters and growth was found between temperature and growth. The biochemical-blood results show us that the nutritional condition of the organisms in culture in comparison with the wild organisms. Using biochemical-blood techniques gives us the advantage of sampling broodstock in captivity without the need to sacrifice them to know their condition nutrition and state of health in which they find themselves.
