| Profile |
| General Description: A beach seines is a seine net operated
from the shore. The gear is composed of a bunt (bag or lose
netting) and long wings often lengthened with long ropes for
towing the seine to the beach. The headrope with floats is
on the surface, the footrope is in permanent contact with
the bottom and the seine is therefore a barrier which
prevent the fish from escaping from the area enclosed by the
net. Two basic types of gear can be distinguished: seine
nets without a bag (Fig. 1) and seine nets with a bag (Fig.
2). The first one do have, however, a central part with
smaller meshes and more slack, which retains the fish
caught. In the second one the fish are retained in the bag.
It is not necessary for the bag to be exactly in the centre
and in this case the wings are not of equal length. |
| Specific Handling Equipment: No specific gear handling equipment
is required for fishing operations but a large number of
people for towing the seine to the shore. In some cases,
wooden-made capstan can be fixed on the beach for
facilitating the hauling of the seine to the shore. |
| Fishing Vessels using this gear: Beach seines are usually set from a boat
(in general, a small boat, in many cases, without engine). |
| Fishing Operations: When setting the first towing line is
fastened ashore, then the line, the first wing, the bag,
second wing and second line is set out in a wide arc and
brought back to the beach. The bottom and surface act as
natural barriers which prevent the fish from escaping from
the area enclosed by the net. The drag lines are towed
simultaneously from the beach. The fish is herded in front
of the bag or bunt. For successful operations it is suitable
that the groundrope reached the beach first, to bring the
gear underneath the fish. |

| Target Species: Demersal and pelagic species |
| The Gear and its Environment:
|
| Deployment Area: Beach seines are generally used near
the shore in shallow waters either in inland and sea waters. |
| Impact on Aquatic Species: Shallow waters close to the shore
are often spawning or nursery grounds. Beach seining
in such areas disturb the breeding activities and
lead frequently to the capture of juveniles. For
these reasons, the use of beach seine is in a number
of countries regulated/restricted by law. |
