Impact of ring net on the mackerel fishery at Calicut

With the introduction of ring net, there was considerable improvement in the mackerel fishery. The mackerel landing was almost fully contributed by ring net. During post-ring net period,16684 manpower brought 970 tonnes of mackerel with a catch per manpower of 58.14 kg. Due to the small mesh size of ring net and their better efficiency, the gear can cause over fishing and hence the fishery has to be watched closely in the coming years.
