Comparison and evaluation of the performance of the mineral mix supplemented diet for asian seabass (Lates calcarifer) culture in fresh water-based recirculating aquaculture system

The major minerals required by fish are calcium, phosphorus, manganese, sodium, chloride, potassium, chlorine, sulfur, selenium and magnesium. Even though we know that fish requires minerals, the quantity required is not studied in combination. In this study, an experiment was carried out to as certain the concentration of 8 minerals mentioned above in the feed in a fixed concentration of calcium and phosphorus at a 1% level of supplementation. This experiment provides valuable information based on growth data, biochemical parameters and hematological parameters.

The experiment was carried out for 60 days in a 500-liter PE tank fitted with a Recirculating Aquaculture System and fed with a mineral mix of eight macro and micro minerals from 0.1% to 1% in triplicates. The mineral analysis was carried out using AAS, biochemistry analyzer was used for biochemical and the hematology analysis was used for blood parameter analysis.

The results show that mineral mix with 8 macro and micro minerals such as manganese, sodium, chloride, potassium, chlorine, sulfur, selenium and magnesium is required at 0.8%. The growth parameters, biochemical analysis and blood parameters confirm the results.
