Effects of desalination brine on the fecundity of brine shrimp Artemia franciscana fed on rice bran

Brine water drained from the desalination stations represents environmental concerns because of its extremely high salinity. Artemia (brine shrimp) is one of the crustaceans that can live in increased saline water. So, it can live in the desalination brine water. This study investigated the possibility of growing Artemia (Artemia franciscana), an essential live food for the aquaculture industry, in the brine water disposed of during the desalination process. Nine reproductive characteristics were examined for Artemia growing in desalination brine water, compared to seawater. Both types of water were brought from the Rumaila water desalination facility on the Mediterranean Sea in Marsa Matrouh, Egypt. The experiment includes brine water of salinities: 50, 60, 70, and 80 ppt and two seawater salinities: 38 and 50 ppt. The food source used was the rice bran suspension to feed Artemia during the experiment. The results illustrated that the prereproductive and reproductive periods and % offspring encysted had higher values in higher salinities of brine water than seawater. The rate of offspring encysted in the brine water of 70 ppt reached 72.42%, followed by the brine water of 60 ppt. The results showed that the Artemia could grow in the brine water of the desalination plants till the adult stage. The results show no significant difference between both types of water in some variables.
