Bacteria to Replace Fishmeal


From Abstract: The cyanobacteria Arthrospira (Spirulina platensis) contains high quality protein and immunostimulatory properties that have been tested in mammals, fish and crustaceans.  In this study, it was fed to white shrimp (Penaeus vannamei) for 50 days to evaluate its affect on growth and immunological parameters.   Experimental isonitrogenous diets (~ 35% protein), containing 0%, 25%, 50%, 75% and 100% A. platensis, were used to replace fishmeal.


The results showed that up to 75% of fishmeal could be replaced by A. platensis without affecting survival or creating growth depression.  Moreover, the smaller substitution level (25%) promoted an enhancement of the tested immunological parameters.
