Abstract:

Chemoreception is an important mechanism governing the process of food searching in many aquatic animals. Numerous investigations have demonstrated that chemostimulants, infused into the controlled environment of several decapod crustacean species, trigger almost identical feeding behaviors to those which are displayed by these organisms when a food item is presented [1,2]. Crustaceans are attracted to artificial food pellets by following an attractant “plume” originating from the food source N. Behavioral analyses of feeding responses were carried out on Macrobrachium rosenbergii prawns, showing that food searching, as well as substrate probing, were greatly enhanced in the presence of aqueous solutions of identified chemoattractants [3]. In a laboratory experiment using M. rosenbergii prawns, it was found that after 2 h, virtually no attractants for this prawn could be detected when aqueous extracts of the pellets were tested in a serial manner. In the present study, the effect of chemoattractant introduction, 2 h after food administration, on the growth of juvenile M. rosenbergii freshwater prawns was tested under laboratory conditions.
