Live Microalgae-Based Diets as Enrichment to Improve the Nutritional Profile of the Calanoid Copepod Acartia tonsa (Dana, 1849) Nauplii

Table 2

Concentration of rotifers (Brachionus plicatilis) and the number of females, as well as nauplii of calanoid copepods (Acartia tonsa) measured in culture tanks during the feeding experimentation using three microalgae treatments (R, Rhodomonas salina; I–R, Isochrysis galbana + Rhodomonas salina; T–R, Tetraselmis suecica + Rhodomonas salina).
