Abstract:
The free-living nematode Panagrellus
redivivus was mass produced on a solid culture medium enriched with
sunflower oil or fish oil by means of a new technology. Nematodes with
different fatty acid compositions were obtained. A 7-day experiment was
performed in order to compare the lipid enriched nematodes with Artemia
as live food for first feeding common carp (Cyprinus carpio L.)
larvae. Larvae fed nematodes doubled their body mass and had a mean survival
rate higher than 80%. No significant differences could be observed between
the two groups fed nematodes. Fish larvae fed with Artemia showed
almost no mortality and had a final body mass five times higher than larvae
fed nematodes. It is concluded that mass produced nematodes are a promising
food source for first feeding common carp larvae. However, further research
is needed on the development of improved culture media to increase the
nutritional value of P. redivivus.
