3.2.1.2.Nutritional value of Daphnia
The nutritional value of Daphnia depends strongly on the chemical composition of their food source. However, since Daphnia is a freshwater species, it is not a suitable prey organism for marine organisms, because of its low content of essential fatty acids, and in particular (n-3) HUFA. Furthermore, Daphnia contains a broad spectrum of digestive enzymes such, as proteinases, peptidases, amylases, lipases and even cellulase, that can serve as exoenzymes in the gut of the fish larvae.
