Abnormally coloured Plaice, No. 818. 
2.— MIGRATIONS OF THE DAB. 
The common dab is, as has been apparent from the trawling 
experiments, an important member of the flat fish fauna of the 
inshore waters, rivalling the plaice, in fact, in the southern sandy 
stretches for predominance. 
The previous experiments of Fulton* showed that the dab 
migrated to a larger extent than the plaice, but the results did not 
point to any definite direction being followed, and no details were 
furnished as to the sex of the recaptured fish. 
The accompanying table (page 74) exhibits the results of our 
experiments with reference to the migration of this form to the end 
of the year. The returns are too few to lay any stress upon, but it must 
be pointed out that the females show a tendency to remain in the 
district, while the males, in the case of the two which have been 
recovered have migrated to a considerable distance to the south, 
and into deep water. 
A labelled dab was captured E. by N. of Souter Point on 12th 
October, but the numbered portion of the label was lost by the fisher- 
man. The dab measured 6 inches but the sex was not stated. In the 
light of the other results, there is every probability it was a male.
