Abstract

The size and amount of food consumed by cultured larval snow crab, Chinoecetes opilio (from the first stage zoeae to the megalopal stage), were investigated, by feeding with L-type rotifer and various sized Artemia sauna (Artemia nauplii from North America reared using compound feed for Artemia). The first stage zoeae mainly fed on zooplankton smaller than the size of Artemia nauplii (total length 0.54 mm). The second stage zoeae mainly fed on Artemia (up to a total length of about 1 mm), and the quantity of food consumed was about 3 times as much as the first stage zoeae. Megalopae fed on all sized Artemia in this test (up to total length 1, 82 mm) and the quantity of food consumed also increased.<BR>To use various sizes of Artemia and rotifer together from the zoea the second stage is expected to improve the culture of larval snow crab.
