TUNA PURSE SEINER

Post by aukepalmhof » Wed May 31, 2017 9:14 pm

A purse seiner is a fishing vessel which uses a traditional method of catching tuna and other school fish species. A large net is set in a circle around a school of fish while on the surface. The net is then pursed, closing the bottom of the net, then pulling up the net until the fish are caught alongside the vessel. Most of these types of vessels then transfer the fish into a tank filled with brine (extra salty refrigerated water). This freezes large amounts of fish quickly. Trip lengths can vary from 20 to 70 days depending on the fishing. The fish is held in refrigerated brine tanks and unloads either directly to the canneries or is trans-shipped to carrier vessels to freight to the canneries, leaving the purse seine vessel close to the fishing grounds to continue fishing. Purse seiners longer than 70 metres are called super seiners.

The tuna fishing boat, called tuna clipper at Nauru is not identified, she is under two gantry cranes with I believe hoses connected to the ship. What the reason is, possible for supplying the vessel with fresh water and fuel. I don’t think she is loading phosphate.
The chase boat on the afterdeck of the tuna vessel is visible.

Industrial purse-seine operations capturing multiple species but largely targeting skipjack (70 – 85 percent of total catch) and yellowfin (15 – 30 percent), where a fishing vessel sets a net in a circle around a school of tuna by first releasing one end attached to a buoy or skiff, and then releasing
more of the net as the vessel moves around in a large circle until the two ends are brought together and retrieved, and the purse seine wire that runs through the rings around the lower weighted edge of the net is hauled to cinch the bottom closed.
