Larval stages of the Botan shrimp Pandalus nipponensis Yokoya, 1933 (Decapoda: Caridea: Pandalidae) under laboratory conditions, with notes on its lecithotrophic development

Abstract

The complete larval development of the Botan shrimp, Pandalus nipponensis Yokoya, 1933, is described and illustrated based on laboratoryreared material. Four larval stages (stage 1-4) and two postlarval stages (stages 5, 6) were recognized. The larvae started to feed on Artemia nauplii from stage 2. Starved larvae survived until stage 3. According to Gore's (1985) classification of the developmental types of decapods, the development of P. nipponensis is of an advanced and lecithotrophic type.
