SCOOP
NET FISHING
Scoop
net is operated widely in Thai coastal waters. Fishing
gear is simple, consisting of a net and two poles to keep
the net open. A small version of such a net is hand
operated by a fisherman (scoop net), while larger nets are
pushed by an engine-driven boat which can be any size between
a long-tail boat and a trawler. The latter type of
scoop net is better known as push net.
According
to the fishery statistics from 1990 to 1997 the annual catch
from scoop net has been increasing, particularly and highest
in 1996 (41,730 mt). This increase of catch is due
to the catch from push net fishing (Table 9.1). The
catch from push net is increased gradually from 1990-1998
and highest in 1996 (29,790 mt). As can be seen from the
table 9.1 that the catch from push net fishing in 1997 (28,648
mt) become more than twice of the catch in 1990 (14,176 mt)
while the number of push net fishing boats in 1998 (901 units)
less than in 1990 (970 units) (Table 9.2)
