Rearing of Plaice

Abstract

IN NATURE of July 12 (p. 251), there is an interesting note on the rearing of larval plaice at Plymouth, by Mr. J. T. Cunningham, in which it is mentioned that they have been reared to the age of thirty-seven days; but it is not stated how long the incubation went on. It may be interesting to say that at the Fishery Board's Marine Hatchery, at Dunbar, I succeeded in preserving many millions of larval plaice from twenty-four to thirty-three days, counting from the time of fertilisation; and some were reared in jars for longer. On one occasion I kept them in a thriving condition to the forty-seventh day after impregnation of the eggs, at which age they were carried away by an accidental overflow. The eggs were fertilised on April 3, hatched on April 19, and laræ reared until May 20, when the accident occurred. A description in full will be given in the Fishery Board's report.
