Abstract
The prototype design and function of a low maintenance larval rearing system for Brachyuran larvae are described in this paper. The rearing system consisted of an array of 1000 ml beaker-shaped polypropylene unit series. The model conceived and constructed in the present study finally concluded upon 1000 ml rearing vessels than 50 ml or 500 litre modules. Water change in this new system is not only far less stressful to the larvae but also less time consuming. The novel brachyuran early larval rearing system designed in this study may be useful to overcome the mortality of larvae due to stress and as it is simple and low maintenance, it could be easily applied in any aquaculture/fisheries units.
