Study of biochemical parameters of Artemia franciscana fed with microalgae Isochrysis galbana and Tetraselmis suecica cultured with different carbohydrate sources

In this study, the biochemical parameters of Artemia franciscana fed with Isochrysis galbana and Tetraselmis suecica microalgae cultured with different carbohydrate sources were investigated. Glucose, sucrose and fructose were used as different carbon sources. Artemia was cultured under standard conditions in 24 circular polyethylene tanks (8 treatments and three replications) with a volume of 300 liters and a density of 1000 nauplii per liter of water. The breeding period was 30 days. The results showed that there was a significant difference between different treatments of cultured microalgae with different carbohydrate sources in terms of biochemical parameters (p<0.05), and between treatments of tetraslimas microalgae cultured with sucrose in terms of protein, fat, Ash and carbohydrates showed significant differences with other treatments (p<0.05). In Isochrysis microalgae, sources of sucrose and fructose caused the highest amount of protein (p<0.05). Analysis of biochemical values in Artemia fed with two groups of microalgae showed that there is a significant difference between different treatments (p<0.05); Among the treatments, Artemia fed with Tetraselmis microalgae and Isochrysis cultured with sucrose showed a better condition than other treatments. Therefore, it can be concluded that the values of biochemical parameters of Artemia fed are related in the first place to the type of algae and in the second stage to the nutritional source of algae. Therefore, the use of both studied algae species grown in different carbohydrate sources can increase the nutritional value of Artemia; But in general, the treatment of Tetraselmis containing sucrose has the highest nutritional value compared to other treatments in Artemia.
