Identification Manual for Larvae of Commercially Important Crabs in Japan.

I. Practical Techniques for Observation in Identification of Larvae

Kooichi Konishi*° and Norikazu Shikatani*z>

In identification of the larvae of commercially important crabs, technical knowledge for

larval identification is very poor in Japan. This paper aims to give practical techniques for

observation in larvae of decapod crustaceans, i. e. fixation, dissection, optical observation,

and identification. These techniques, which are easy and useful, facilitate both observation

and identification of crab's larvae. Annotated list of basic equipments for dissection and

observation and basic identification procedure in higher taxonomic level, classes and in-

fraorders, are also given.

Key words : Anomura, Brachyura, Crustacea, larva, methods, plankton
