Rotifers As A Production Diet For Striped Bass Fingerlings

Growth of striped bass Morone saxatilis fry on a diet of rotifers was studied in the laboratory and in the field. Although the rate of growth was slower when rotifers were the principal food than when other acceptable zooplankton were eaten, rotifers were judged to be acceptable as a starting diet. This was based upon the fact that survival was higher and more consistent from pond to pond than was the case when mixed zooplankton was the source of food initially. Trichlorfon as Masoten® was used in rearing ponds to reduce predaceous and competitive invertebrates and to favor development of the rotifer population.
