The National Fish Workers’ Forum has threatened to organise a broad-based protest, including a sea parade from Kutch to Kanyakumari, to press their demand for withdrawal of a notification on the shipping channel off the Indian coast. Forum general secretary T. Peter said protest was organised at 43 maritime centres in the country on Tuesday as part of the programme to raise the demand for cancellation of the notification. The fishermen fear that the shipping channel notification would keep traditional and mechanised fishing boat operators out of their traditional fishing grounds and that they would lose their means of livelihood. K.V. Thomas, MP, inaugurated the protest at Fort Kochi. Cochin Port Labour Union secretary B. Hamsa presided at the protest meeting, said a press release here.
