(Received, Jttlle 1949).
The material for thi. paper wa ohta in ed in 1948 durin g a
four month' vi it to th e Malay state. The tour was
ctioned by
the Travancore Governmen t, a t the ug(re tion of the Go,ernment
of India . It object \Va to tudy the method of ring-net fi bing"
practised in Malayan and . iame e water, and to investiO'ate the
possibility of introducing it in Indian water. The author W"a ;
af'si ted considerably hy the whole-hearted co-operation of
Mr D . ,V. Le Mare (Director of Fi heries, Federation of Malaya..
and ingapore) and th member of hi
tatf and b~r the many
fllc ilitie afforded him by )1r C. P. hen, proprietor of the Malayan
F i herie , Pangkor.
Both fre h and pre en-ed mackerel are in great demand in
Malayan market, and the industry i one of the most important
fi heries in the country. Before the war th e annual output per heaa
of the Pangkor purse !'ein e fi hermen wa about 10 ton. Thi
compare fayourably with the 8.3 ton of the Japalle e Bream fi hermen during the same periocl. and the 1.5 tons of the :Malay fi hermen
of the ea t coa t., In 1941, 13.:1,,5 0 piculs 1 (159,80.:1,. 82 cwt ) of
mackerel were la1ll1ed in Pangkor by thc ein e 11 ts . Thi formed
58% of the total catch for Perak, ~hich produces more fish than
any other tate in the F deration. The greater part of thi was"
_ent to the ingapore market. and the remain(ler to rr'elok An 011,
Ipoh and Kuala Lumpur. 38,859 piculs of fi h were landed at
Kuala Kedah in 1947, more than 65% of which wa made upof landinas from the pur e eine boat . Thi al 0 found it mainmarket in Singapore, some 560 mile away, while a small portion
wa distributed in the neighbouring towns of Alor tar, Sungei:
Patani and Penang.

HISTORY OF THE PURSE SEINE IN
YA
About 1877 a group of Uh inese fi hermen from Pakboi
in South China miarated with their boat and net to iam, where·
they began fishing for mackerel (KiJmbong) . Later the majorityof them mo\'ed farther outh to :Mala.·a and ettled at Kuala Kedah,.
while a few went a far a Pangkor, an i land off the coa t of Perak.

Federated Malay tates, the men who had ettled in Kedah follo",,:ed
the others down to Pangkor. Thirteen years aO'o the pur e seIDe
,va taken back to Kuala Kedah by a Chinese fisherman, and was
'u
uently adopted with light modification by the local Malays.
Kuala Kedah and PanO'kor are till the only place in Malaya
where pur'e eine fi hing i carried on on a large scale, though
thi net has recently been tried at Mer ing on the east coast of
Johore. Originally the net were operated from
. boats, but
in recent years, at the ugO"estion of the Department
Fisherie ,
the e have been replaced by power-driven boats.
When power fi hing wa tarted there were only 14 boats
operating from Pangkor, but the number ub equently in crea ed
to 44 during the pre-war period. In 1948 there were about 30
pur e eine boat on Pangkor J land: 19 in the village of ungei
l'enanO' Kechil and 11 in the village of Pangkor. All were owned
and worked by
.
fishermen. In the Keelah area there were
24
seine boat in the village of Kuala Kedah, 3 in the viJlaO"e
of uala Per' and 2 in the villa O'e of Yen.
ix of the 24 net
in Kuala Kedah were owned and worked by Malay fi hermen. The
remainder were owned by Ohine e merchant. Six of

by Ban Hock Lee F isheries wa~ found to be simil~r to the. Pangkor
net, measuring ] 60 fathoms In length and 30 fathoms III depth,
while the net owned by Ahmed Majid, a Malay fisherman, was only
140 fathoms by 25 fathoms .
'The Chinese nets show a rather
uniform depth. with a slight decrease at the tips of the wings. The
Malay nets deerease gradually in depth from the centre piece to
the wing nets.
.
( a)
Chinese net.
A typical Chinese net consi t of a centre piece (or Codend)
of strong net with a number of pieces on each sille. A net measuring 152 fathoms has a centre piece of 12 fathoms length and 25
fathoms depth, with 10 7-fathom pieces on each side. The length
of the centre piece varies in different net. A Pangkor net 180',
fathoms long was founel to ha\'e a centre piece of 20 fathoms length,
while in Kedah a net of 160 fathoms length had a centre piece of
3·0 fathoms. The centre piece has a half inch mesh of 12/208
yarn (3 x 4 ply), the adjoining pieces on each side have a half inch
mesh of 9/ 20 yarn (3 x 3 ply) or 8/20S, and the remainder of
. Sometimes 4/ 20S yarn
the net a half inch mesh of 6/ 20S
is used for the wing nets. The m
measures slightly more than
half an inch when the net is new, but it shrinks to the exact size
after treatment in cutch and long use. The centre piece and the
adjoining nine pieces have a uniform depth of 25 fathoms; the
last pieee has a reduced depth of 22 fathoms (Fig. 3.).
The two head and two foot ropes are usually of ~ inch manila .
.sometimes they are slightly thicker. Along both head and foot
rope is a hodd ing of about 25-30 me he" which runs the entire
length of the net. This is made of 12/ 20S yarn and serves to
increase the trength of the net. In a short report of the Pangkor
purse seine prepared by the Fisheries Department it is stated
that the hodding shows a variation in breadth towards the centre
of the net. This variation was not seen in any of the nets examined.
Wooden floats, each measurinO' 9" x 5'" x 2" and biconvex in shape
are fastened along the heac1 rope at intervals of about 10" . They
are mac1e of Uton.q wood and are attached between the two ropes
in such a way that they always float with their flat surface upwards (Fig. 4.). 'The last piece of the net is devoid of floats. The
purse rings, about 76 in all, are attached along the foot rope at
intervals of 1 0
2 fathoms. About 2 3 fathoms of the centre
of the net and. the last piece in the wings have no rings. The first
two rings in the centre are large and heavy. Each is actually a:
combination of two rings; a large one and a small one rotating on.
a swivel (Fig. 5.) . JI'he large ring is attached to the net, whil e
to the small Oile is attachec1 the enc1 of the pursing- rope of

(2 x 4) yarn and the rest a half inch mesh of 6 plJ: yarn. rr'hehodding is not so prominent as in the
net (..I!lg. 8.).
IThe floats measure 8" x 40" x 2" each and are placed at.
intervals of 6 8 inches. These floats are also of wood and are'
similar in shape to those on the Chinese nets. The swivel
rings are placed about 20 feet apart at the centre of the
net and the other rings are attached at intervals of 7Y2 feet. Theserings have all external diameter of 3~" and internal diameterof about 3". Sinkers are attached only to alternate rings, and
weigh about one kati each (1.33 lbs.). The tips of the wings for
a distance of about 6 fathoms are devoid of floats a.nd rings, as in
the Chinese net. The head ropes, foot ropes and pursing rope are'
also similar to those of the Chinese net.
( c)
Treatment of Nets.
The only material used for the preservation of the net is thebark of the mangrove tree, which is abllndant ill the swamps lining'
the coast. It is used both fresh and after drying. T'he fresh bark
is soaked in water for about 1 2 'weeks, while the dry bark i oaked
for 2 3 weeks, -or 1m til the solution turns deep red in colour ~
The net is then steeped in this brew, section by section, until it
acquires a dark red tint. After being steeped, the net is rinsed,..
wrung out and dried in the sun. All these operations are usually
done by hund. Sometimes, to facilitate the process, the bark is.
boiled in water and the net steeped in the hot solution.
(d)
Drying the Net.
A special platform and framework are generally erected forhanging the net to dry after use. '1'his frame is always situated.
near the factory building and within easy access from the fishing '
boat. It consists of two rows of 4 long poles, each about 40 it in
length. '1' he upper ends of opposite poles in the two rows areconnected by horizontal beams, and the sides a.re strengthened by
cross struts. The whole structure has rather the appearance of a,
rectangular tnnnel. Below, at a height of 3 4 feet above thehigh tide level, is a tage of spl it Nibong or Pen(1ng, running the
entire length of the drying platform. There are usually 10
horizontal poles with a pulley at each end, from whi h ropes run to
blocks on the topmost rail, for raising the net on the frame .

The movable 'short poles are dropped to the platform and thenet laid on them, with the codend towarc1s the shore and the wing _
at the seaward end of the drying stage. IThen they are raised about
four feet above the platform and the net spread uniformly a.nd
properly. Finally they are pulled up and secured, so that the net:
hangs in the air from the top of• the scaffolding .
