| Profile |
| General Description: A ring net is a surrounding net the form of which is
intermediate hybrid between a purse seine and a lampara net : like on a
purse seine, rings at the lower edge of the net, allow using
a purse line to close it under the fish (pursing) and like
on a lampara net, there is a central bunt (with smaller
mesh) in which the capture concentrates as the two wings are
hauled together and the leadline being shorter than the
floatline give some how a
spoon-shape as in lamapara net. |
| Specific Handling Equipment: A small capstan and a derrick are
usually all the special equipment required. The fish is
removed from the net by means of a scoop
net or brailer. |
| Fishing Vessels using this gear: Vessels using ring net are usually small
and simple in respect to equipment, a range around
12 to 24 meters length . |
| Fishing Operations: Most ring net boats work on two-boat system
which is much handier when the net has to be towed. When a
suitable shoal of fish is located and both vessels are
ready, the first vessel will drop its marker light over the
side and proceed round one side of the shoal, paying out
bridles and net. After the aggregated fish has been
surrounded, the purse line is hauled for pursing/closing the
bottom of the net. Then the two wings are pulled on board at
the same time and the fish concentrate in the central bunt.
Finally, the catch if taken from the bunt, aside of the
boat, by using a scoop net. |

| Features |
| Target Species: Pelagic fish |
| The Gear and its Environment:
|
 | Deployment Area: The gear is only used to catch fish
close to the water surface, in both marine and inland waters. |
 | Impact on Aquatic Species: The potential negative impact may
come from occasional bycatch/discards effects
(undersize specimens, no marketable specimens, non
target species, etc.). |
