Ribbon-fishes constitute one of the important commercial fisheries of India, the annual catches fluctuating about 29,000 m. tons and forming 3 80% of the total marine fish landings (average for 1958-67). They are caught almost all along the Indian coast and form an exclusive fishery of considerable magnitude at a number of places, especially in the southern peninsular region. The States of Andhra Pradesh, Madras and Kerala account for the greater percentage of annual catches. A limited fishery exists in Hooghly-Matlah estuaries. Though the catches are constituted by more than one species at several places, it is certain, that the bulk of the catches are contributed to by Trichiurus lepturus which moves in great shoals and appears to migrate from east to west around Cape during August to October when it is caught in large quantities. On such occasions, the fishery is supported by spent fishes, about 50 to 75 cm, which could be caught to any extent possible without being detrimental to future stocks as such fish would have spawned at least once. The other three species, Lepturacanlhus savala, Eupleurogrammus muticus and E. intermedius, though comparatively not very important, yet form the fishery singly or cojointly at some places. The usual gear for these fishes are the shore seines and the boat seines. Catches could be substantially improved in the southern region between Idinthakarai and Vizhingam if the information of appearance of shoals between August and October is promptly passed on to the fishing centres in between and they arc effectively fished at this time.
