For the time being we do not have enough information concerning the early larval growth of marine fishes hatched out from pelagic eggs. Such information is useful in considering the periods required by the fish larvae to attain certain sizes from the time of hatching.

It should be noted that we have to be careful in comparing the results obtained from these experiments with those in the natural environment, because in the former case the larval growth depends largely on the rearing techniques. This paper is only a preliminary report on some examples of early larval growth observed in the rearing experiments.
