Ingested quntity, digestive veloity nd somti growth were ompred etween lrve fed freshwter rotifer nd those fed oiled yolk. Food effiieny nd somti growth were ompred etween lrve tht were fed freshwter wter fles nd those fed miro-diet developed for flounder (25 μm, I-hw Ltd.). The numer of rotifers ingested y lrve rehed mximum of 191 per dy. However, sed on the numer ingested per hour nd the digestive veloity of onsumed rotifers, the mximum ingestile nd digestile numer of rotifers ws lulted to e 272 per dy. A mximum of 67 individuls (men, 49.8 individuls) ould e ompletely digested within the 1-h period from 9 to 18 min fter feeding. Somti growth ws enhned in lrve tht were fed rotifers ompred to those fed oiled yolk. Lrve exhiited greter growth t rotifer densities of 3 nd 4 per ml thn t lower densities. Among the wter-fle (M. mroop nd Bosmin sp.) nd miro-prtile diets, feeding with M. mroop resulted in the gretest somti growth of lrve during the wter-fle feeding stge.
