Hook and line fishing has been used for the last two decades along the Vizhinjam Coast targeting mainly tunas especially bullet tuna. The fishing methodology is in use for more than several decades, but systematic study in relation to the modifications in fishing practice and its impact on the improvement in catch and income generation of fishermen has not yet been done. This paper aims to bring out the modifications in the gear/ craft and area of operation of line fishery and its impact on the income generation of fishers in the Vizhinjam Coast.
