Abstract
Live feed are still necessary for the rearing of larval stages of several fish species, especially marine ones. Compared to Artemia, copepods are of superior quality. This is based on a suite of traits like size, movement, and nutritional value. Copepods are for example usually high in protein and fatty acids. Essential fatty acid profiles reflect to a large degree the fatty acid supply, which provides the opportunity to manipulate fatty acid profiles of, amongst others, copepods. By manipulating nutrient supply of the algae Rhodomonas salina we were able to double essential fatty acid concentrations in naupliar and copepodit life stages of the copepod Acartia tonsa. However, this lead to growth depression rather than to increased growth rates in a series of consumer species, including larval fish. The reason for the growth depression is likely to be mineral deficiencies occurring along with the nutrient manipulation of the algae.
