Profile |
General Description: A seine net is a very long net, with or
without a bag in the centre, which set either from the shore
or from a boat for surrounding a certain area and is
operated with two (long) ropes fixed to its ends (for
hauling and herding the fish). Two types of gear can be
distinguished in this category: beach seines and boat seines
|
Specific Handling Equipment: While, no specific gear handling
equipment is required for beach seine operations, the
problem for manoeuvering seine nets in general consists,
first, in hauling the long ropes attached to the ends of the
net: this is done either by hand ( beach seine ) or with a winch
( boat seine ).
When seine nets are used from boats, rope
drums can be used for storing the long ropes,
a power blocks can also help for bringing the net on board. |
Fishing Vessels using this gear: For the operation of a beach seine, only a
rather small undecked vessels may be necessary fro setting
the net. The boat seine are operated from a wide range of
rather small and simple boats and by modern specialized
medium size units with specific deck equipment. According to
the fishing technique used, seine nets can be operated by to
medium and large decked vessels. |
Fishing Operations: Seines are usually set from a boat to
surround a certain area and are hauled either from the shore
(beach seines) or from the boat itself (boat seines). |

Target Species: Mainly demersal species, less frequently
for pelagic species |
The Gear and its Environment:

![](../assets/images/invidot.gif) | Deployment Area: Seine nets are operated both in inland
and in marine waters. The surrounded and catching area
depends on the length of the seine and of the hauling
lines. The seine nets are used, in marine waters, on the
continental shelf, from the coast to down to 500 m and
are very common everywhere, lakes, large rivers, etc. |
![](../assets/images/invidot.gif) | Impact on Aquatic Species: The potential negative impact may
consist in the bycatch/discards (undersize
specimens, no marketable specimens, non target
species, etc...) and results from the use of a large
net, with, frequently, too small meshes, in coastal waters. |
