Abstract: Several herbal materials have been in use for alluring fish during harvest and angling by traditional farmers in different parts of India. Experiments were conducted using behavioural trough to evaluate 10 herbs collected from Tripura state as feed attractants on post larvae of giant freshwater prawn (Macrobrachium rosenbergii) and fingerlings of Indian major carps catla (Catla catla), rohu (Labeo rohita) and mrigala (Cirrhinus mrigala). The herbs used in the study are jatamansi, ekangi, latkhandhana, jayatri, kakla, latakasturi, aobel, bhuski, kharbaz and tambul. The powdered herbal materials were incorporated in starch at 1% level to make a dough and it was placed in different compartments of the trough for evaluation. The results of experiments clearly demonstrated higher feeding attractant activity of herbal materials compared to commercially available chemoattractant, betaine. The post larvae of freshwater prawn were attracted in greater numbers towards ekangi, kakla and bhuski compared to betaine. The attractant activity of different herbs was found to be species specific in case of Indian major carps. The highest attractant activity was shown by latkhandhana on catla, kakla on rohu, and kharbaz on mrigala.
