Gill Netting
Gill Netting is one of the oldest harvest methods.
A wall of net is set across the path of fish.
The netting is usually equipped with weights at the bottom and floats at the top.
As the fish swim towards the net and try to pass through it,
they will be trapped if the heads of the fish can pass through but not
the rest of the body. The fish are entangled as the gills are caught in the webbing
and cannot back out.
Fishermen can adjust the size of the mesh to determine which species or the
size range of the fish they want to harvest.
Long-lining
Long-lining involves setting up two buoys; under each buoy,
there is a buoy line lied vertically.
A horizontal “long line” is tied at the bottom ends of the two buoy lines,
and there is an anchor and a series of hooks and baits connected to the long line.
Fish will be hooks as they try to eat the bait, and the harvest is completed when the fishermen hauled
back the long-lining set.
The anchor attached to the long horizontal line can determine how deep the hooks attached to the line can be in the sea,
so that fishermen can decide fish from which area of the sea they want to catch.
The size and species of the fish can also be determined by the size and shape of the hooks,
and what kinds of baits are used. Commonly used baits include sardine, worms, squids, crabs and shrimps.
Seine Netting
This method is about encircling fish by a net.
The fishermen warp the netting and surround the fish,
and the close the bottom of the netting, so that the fish cannot escape.
When the fishermen try to pull and haul the whole netting aboard,
the opening at the top of the "purse" gets smaller and become closed,
and the harvest is complete.
While the fishermen can capture a lot of fish at once by this method,
it is very hard for the fishermen to choose what specific species and size of fish to harvest.
