Abstract: | The effect of diet on the frequency of malpigmentation was investigated in laboratory-reared plaice ( Pleuronectes platessa ) fed on either enriched or unenriched Artemia salina nauplii . The juveniles fed continuously on unenriched Artemia during their larval period showed 29.0% normal pigmentation whereas those fed solely on enriched Artemia , showed 63% normal pigmentation. The possibility of a critical period for pigment development was tested by changing the diet of larvae at different ages. Results suggested that a critical period is less important than the duration of time fed on a nutritionally complete diet. |
