Marine fisheries production and number of units from among the
sector from 1990 to 2005
Conversely, the pelagic fishing using purse
seine contributed only about 1,235mt in 2005that is way below
the expected MSY of about 7,000 metric tons per year. This means
that the potential increase in the capture fisheries production
relies on the development of the pelagic fishing especially
in zones 3 and 4.
In general, the marine capture fisheries have
continuously provided more or less of 50%of the country’s
supply of fish for over 20 years. And in recent years, a significant
chunk in the local fish production of about 70% or about 12,329
mt (in 2004) is contributed by the small-scale fisheries sector.
Majority of the fishermen in this sector are operating in zone
1, fishing area of within 3 nm from the shore. They use outboard
engines to reach the fishing destination and operate the small-scale
fishing gears such as trammel nets, hooks and lines,pots to
name a few. Some had modernized their fishing techniques using
electronics device such as the application of GPS, echo sounder
as well as the fish finder.
estimated MSY among the small-scale fisheries sector is only
about 6,400 mt (for both demersal and pelagic resources) with
98% from the demersal resources.The demersal fish production
level in 1999 and 2005 (for both small-scale and commercial
sectors) has increased but exceeded the MSY limit thus causing
a decline in fish production in 2005 due to excessive fishing
effort (in terms of fishing days). But despite the excess in
fish production over MSY among major small-scale fishing gears,
there is a general decline in the aggregate CPUE within the
past 5 years or so that might be an indication of overfishing.
level of the fish production among small-scale fishing gears
exceeded the MSY level from 2000 to 2004 ranging from 5,083
mt to 12,239 mt as shown in Figure 3.

production of small scale fishermen using the small-scale fishing
a significant decrease in the catch per unit effort (CPUE) of
the major small-scale fishing gears was noted. It means an increase
in the number and units of fishing efforts (i.e., number of
gears and fishermen and days) assuming catch is set constant
and/or a drop in the catch compared to the earlier years. Figure
4(1-4) shows the CPUE trend of major small-scale fishing
gears in Brunei Darussalam.

Likewise, the number of small-scale fishermen has increased
from 2,070 people in 2000 to 4,810 people in 2004 is as shown
in Figure 5.

change in the number of fishermen.
Number of small-scale fishing gears and estimated MSY.
Based on the CPUE analysis conducted in 2004, the Department
found that about 12 small-scale fishing gears as shown in Table
2 have exceeded the maximum efforts (units). This includes
the following types of gears:
• Ancau (ring net)
• Andang karan (trammel gill net)
• Andang jarang (bottom-set gill net)
• Bubu (fish pot)
• Kabat (barrier net).
• Jaul/pancing (hand lines)
• Pukat kembura (Surface gill-net)
• Kilong (fish coral for deeper water)
• Lintau (fish coral)
• Rambat (cast net)
• Rantau (drift gill net)
• Tugu (tidal weir)
the small-scale fishing gears, Jaul (hand lines) and Andang
jarang (bottom-set gill net) yielded the highest contribution
to the total production and MSY level among the small-scale
fisheries sector. Overall, the aggregate MSY contribution of
the small-scale fisheries sector is more than 6,400 mt based
on the estimates using the fish production models.
OF MARINE CAPTURE FISHERIES
goal of marine capture fisheries in Brunei Darussalam is to
develop the marine fisheries towards the maximum economic yield.
This goal is to be achieved through the formulation and implementation
of the management strategies to increase the productivity, resource
sustainability and equal share among the fishers. In general
the objectives of the management are:
›To fully exploit the marine resources up
to 21,300mt at sustainable level;
›To protect the nursery and breeding grounds through the
establishment of marine protected areas;
›To promote equal sharing of marine resources between
the small-scale and the commercial fisheries sectors;
›To promote the usage of selective fishing gears and environmentally
friendly gears to minimize the wastage of under-sized
›To increase the marine resource productivity through
resource enhancement programs.
Currently, some measures to mitigate the decline
in the production and losses to trawl operation are being undertaken
by the Department of Fisheries. These includes the limited number
of licenses to the trawl fishery, mesh size regulations, zonation
for fishing grounds and encouraging the trawlers to shift to
pelagics fishing such as purse seine and long line operation.
On top of that, the law enforcement capabilities of the Department
have been strengthen in preventing the exploitation of the resources
from illegal fishing.
