Fig. 14. Growth of Branchinecta lindahli reared at 20.0-2l.5 DC in the flow-through system using diet 3. Test culture started with 3 days-old
larvae. Bars represent standard deviations.
Chlorella as food at 28 DC. Lake (1969) reported a
lower growth rate in Chirocephalus diaphanus Prevost, which reached sexual maturity on day 12 at a
standard length of 10-12 mm, when cultured at 25 DC
and fed Scenedesmus.
