Abstract

Maternal stocking density and hence available ration affects both length and dry weight of neonates. As ration per adult Daphnia increased the size of neonates decreased. There was some suggestion that neonate size had an effect on their susceptibility to some toxicants. The results here are not decisive, but are sufficiently indicative to counsel caution in the culture of mothers when generating reonates for tests and to suggest that further research is needed to determine the relationship between size and sensitivity.
