Description |
The marine diatom Chaetoceros calcitrans f. pumilus has been examined for its potential source as live feed in aquaculture. The present study investigated e?ects of temperature (20,25 and 30 degrees C), salinity (25 and 35) and carbon dioxide addition (air + CO sub(2)) on the growth and proximate composition of C. calcitrans under laboratory conditions. The growth and biomass of C. calcitrans were primarily a?ected by carbon dioxide addition, and to a lesser extent by temperature and salinity. In general, lipid and carbohydrate contents were higher at lower temperatures (20 and 25 degrees C), while the protein content was unaffected. Carbon dioxide addition increased protein, while lowering carbohydrates, but had no effect on lipid content. Carbohydrates were increased while lipids and protein decreased at the highest salinity (35 + or - 0.9). These results should be taken into consideration when evaluating the dietary value of this micro alga for aquaculture.
