Traders say though supply will be hit, demand can be partially met with catch from the Arabian sea along Kanyakumari and Kerala coasts, reports TimesOfIndia.
In the Arabian sea, the ban period will begin from 29 May.
Shallow water fishing using catamarans are excluded from the ban and will therefore ease the shortage.
Traders also said there will be a marginal rise in the price of sea food, especially prawns, crab and fish varieties like vanjiram.
A fisheries department official said: "The objective of the ban is to facilitate breeding of fish and increase marine wealth. If not for the ban, marine wealth will deplete at an alarming rate."
He warned that the licences of fishermen would be cancelled if they are found fishing in mechanised boats during the ban period.
During the period, the fishermen will be provided with a compensation of 2,000 per family. Fishermen will also make use of the period to set right faulty engines and overhaul boats.
Seafood to Cost More as Trawling Ban Begins
INDIA - Mechanised boats will stay ashore across coastal Tamil Nadu as the 45-day routine ban on fishing by deep sea trawlers came into effect on Sunday. The ban will start in the Bay of Bengal waters and will last until the 29 May, allowing time for fish to breed.
