ENHANCEMENT OF GROWTH IN JUVENILE FRESHWATER PRAWNS, MACROBRACHIUM ROSENBERGII, THROUGH THE USE OF A CHEMOATTRACTANT

S. Harpaz-1997

Aquaculture, 156 : 221-227

Abstract:

A feeding experiment conducted with juvenile freshwater prawns in which betaine was added as a feeding attractant, resulted in a 17% increase in growth of the group that had chemoattractant augmentation following actual feeding. The chemoattractant was added to the water, in an aqueous concentrated solution of 10^-3 M and induced a burst of food searching behavior leading to further consumption.
