Economic viability of the non-motorized (NM) fishing craft in relation tomotorized-outboard motor (M-OBM) and inboard motor (M-IBM) fishing crafts at three selected coastal marine fishermen villages- Bandaravanipeta in Srikakulam district, Danavaipeta in East Godavari district and Kothapatnam in Prakasam district belonging to three distinct coastal zones of Andhra Pradesh for a period of two years (2003 and 2004). Among the motorized crafts, the returns form M-OBM crafts is fairly good since there flexibility of fishing in the near-shore as well distant-waters. But in the case of M-IBM crafts, the operations are strictly meant for distant water fishing and there is risk of venturing into the deeper regions and also low rate of return on investment (RRI). High operational cost of about 35% to 42% of fuel (diesel) involved in the fishing trips in case of motorisation. Net return per trip by NM was the highest (Rs 15,428) at Danavaipeta at Bandaravanipeta (Rs 42,290) by M-OBM and by M-IBM at Kothapatnam (Rs 43,495). Rate of return was higher in NM boats (33.49%) than in M-IBM (13.99%). Break-even catch were also estimated.
