Examples of trawler

• A total of 540 fish were collected at random from the catch of commercial trawlers during 1982 -83 and 1992 -93.

• Deep trawlers were the single largest harvesting sector in terms of total value of output and net earnings throughout the simulation period.

• Fish were sorted on board by species, and stored in baskets with ice in the cool room of the trawler.

• A number of trawlers were converted and a number of new purse seiners, designed to fish farther offshore, were constructed.

• The effort levels of day trawlers and gillnets were reduced during the first four years.

• The profit margins for purse seines, single-day trawlers and gillnets were relatively less to begin with.

• On the contrary, deep trawlers (35 per cent) had high profit margins among mechanized sectors.

• In our study, the partial removal of cost-inefficient trawlers and gillnets helped ease the crowding effects early on.
