Instructions would be given to fishing boats from other states to go out of Kerala coast, Babu said at a meeting held here to review the preparations for the trawling ban.
The ban would be effected along the Kerala coast up to 12 nautical miles from June 14 to July 31.
Ration food articles would be supplied free of cost to fishing boat workers and other labourers connected with the sector during the ban period, Babu said.
Since then it has been a routine annual affair.
During the ban period, trawlers and mechanised boats are not allowed to enter the area demarcated by the government.
