Abstract
The purpose of this study was to analyze the effectiveness of nematodes (Panagrellus redivivus and Turbatrix aceti), Artemia, and rotifers (Brachionus plicatilis) as diet options for larval Scartella cristata to see how well nematodes could perform compared to the 'accepted' general diet of Artemia and rotifers. Four different diets, three consisting of nematodes, were to be tested in this endeavor to better increase larval performance and production value of this limited commercial species. Previous research, although limited and among varied species, produced mixed success for larval performance on nematode-based diets. Larval performance would be analyzed based on length-weight and RNA:DNA ratios. This information would help define an exact feeding regimen for this species which could translate to other similar blenny species for use in aquarium aquaculture. It may also further support the applicability of nematodes as a diet replacement for other aquacultured fish in the commercial realm. Unfortunately no breeding ever occurred over the study period.
