International Couneil for the

Report of thc 1962 Ieeland Tr').vl Mesh Seleetion Vforking GrouE
.l.ntroduction
Follo-,1ing a requ~str' from j;,g~ Peroancnt Commission, the North-Ylestern
Vlorking Group 1;lD..S set Up~t~'i~~eh'tigate the state of the fish stocks in the
northern part cf the Convention Area outside the north-east Arctic. This Group
was io analyse thc effects on the fish stocks of further increase~ of mesh sizes
above 110 rnm.
During its \lork the Group feIt the need for more selectivity data for some
of the more important species and i t therefore passes the follo·.ling recommendation for the consideration of the Liaison Coml1littee:-
"1. Selectivity datn. for cod, haddock, redfish and coalfish in Icelandio
17aters are needed. It is thought that these could most effectivelyoe
obtained by an international experiment along the linos of those carried
out in the North Sea and thc Arctie in 1959 and 1960. Aeeordingly, the
Group recommends that the attention '.)f the ChairI:lan of the Comparath"e
Fishing Cemmittee be dra\.'l"l to this proposition at an early date, ,Tith a
view to planning an experiment of this kind at the 1961 meeting of the
Couneil".
This reew!D,iJlendation v:as adopted by the Gomparative Fishing Committee at its
1961 meeting and Mr. Jon Jonsnon vas asked to aet as Organizer of the experiment.
Durinn tbe detailed planning he 'lIas assisted by Er. A. R. Margetts, who also
undertook to ..ork out the first results for presentation at the 1962 ICES Meeting.
The experiments v,ere oarried out during the roonths April to September, 1962.
As an outcome of co-operation betveen ICES and IClIAF, Canada also took part
in the experiment.
At tbe 1962 lCES l1eeting, Mr. Eargctts gave a summary of the results obtnined
so far, and at tlutmeeting it vms decided to have the results I'lOrked out in full
detail by a ~iyorking Group. This Group .las to be eanposed of representatives of
. thP. eonntrles v/hieh took part in the experiment. Mr. Jon Jonsson was made
Convenor of tbis Group . . ü th special assistanee by I,lr. Margetts.
The Group met at Charlottenlund, Copenhagen, 3-7th December, 1962.

The EKPeriments
During the summer months of 1962 seven countries . . : rith eight ships took part
in co-ordinated tra.. . ., l mesh seleeticn experiments in Ieelandie waters.
The chief tim of the experiments 'was t::> establish the seleetivity on the
principal oommercial spccies of double-braided manila tr3:v-:l cod-ends. This was
to be done by use of' the covcred eod-end teebnique. Further aims \lere the eomparison oi' selectivities measured by the alternate or paired haul teebniques
. .7 ith those measured by the covered cod-end tecbnique, measurement of the seleetivity of eod-ends made from various other commonly used materials, and investigation of the efi'eet on selectivity cf forL1s of eud-end top-side ehafers.

The Data
The data collected lrere on selection of cod, haddock and redi'ish (type
marinus) by cod-ends made of double manila, double capron, double nylon and
double perlon. In nearly 1111 cases the data collected Vlere insufficient to
derive selection curves for single hauls and, therefore, comparable hauls \"{ere
grouped together. In i:lost c~scs this meant combining hauls made in the same
area i"lithin a short pcriod of days. Exceptions to this ..,-:ere some. data from
ANTON DOHRN, i.:JJli.A. JULIA and G. O. s.:ms, \7hich were combined from different
localities. ";ibere data -,/ere so co;nbined, this "'-;0.3 justified by the similarity
of the length coopositicn of thc catches in thc separate localities.
•
The selection curves \fere dray,n for covcred, alternate and paired hauls.
The percentages retnined in the c'ü-end at each centimetre lcngth ~ere plotted,
and thc curves ',:-ere fitted to these points by eye. Thc 507- lengths, as weIl as
thc selection ranGes, .rore rc;~d off the so constructed curve. These figures
are given in Ta-bles 2-4- Ilhich also ocontain other iteras of infor~ation recommcnded
as relevant in the repcrt of thc ICES Mesh Selcction ·l~-orking Gr:'up (ICES, 1963).
In these tables, values follo';md by a question mark indicate thc rather unreliable results ·dlich ;,fere obtained from meagre or variable data. The selection
range values ...-lere rounded to thc nearest ccntimetre and thc number of fish in
the selection range for cod-end and cover TIere rounded to the nearest tQn fiSh •

During the course of experir.lCnts ~ girth measurements ./ere made on board
A. T. CAl:IERON (cod, haddock and redfish, head and maximum body girth), EXPLORER
(cod and haddock, head girth) , M?rON DOHEN (redi'ish types!ß-~ and mcntell~,
maximum body girth), and HltRIA JULIA (coo and haddock, maxitlum body girth). The
average girths at lengths are given in Tablcs 8,9 and 10.
Data were collected and recorded separately for redfish meshed in the
cod-end. (Table 7). These data \7ere, hcrdever, included "i,·ith the cod-end catches
in calculating the selectiYity values.
In general, al thoueh there "7Cre exceptions, the experioents -.lere not conspicuously successful and the quality of data :.md results ,ras not always as goOO
as might be desired. The most obvious rec.son for this \laS that in the covered
cOO-end experiments thc nelcction range of the r..esh in use frequently did not
match well wi th the length dintribution of the fish available, and in the
alternate ho.ul cxperinents therc ,.ere very marked differences betvreen the length
distributions of thc fish being caught on the same ground from haul to haul.
Thus, with thc numbers of hauls often bcing rather fe·,.[, the selection curves and
the 50% points v:ere not ah;ays clearly defined. A notablc exception to this was
imON OOHRN redfish, and, nmongst the other data, same such as GONCHAROV cOO,
M.ARD'~ JULIA and ERN3ST. HOLT CQd ~vi th large mesh, EXPLORER ::.nd EBNEST HOLT
N. Iceland haddock, and ~illRIA JULIP~ S.E. Iceland haddock yielded r.lore definite
results than the rcmcinder. S':l, in considering all tho results in tables 2-4,
it is reasonable to attribute a substantial araount of the variation in selection
factors to experimental variation.
Conclusions
Cod. Nine sets of data gave selecticn factors for cavered cod-ends of double
manila,of which t"lW are of doubtful validity. Thc orilinary umreighted average .
of these nine values is 3.2 ~.hich is unaltercd if the ,ty;O less reliable figures,
2.8 and 3.3, are ooittcd. The range of selQction factors is 2.8 to 3.4- The
summary tables do not point to any relatianshipbe~~een size of catch and .selection fact er , but thc grouping of the data in thc surnnary tables could mask any
such effect. Hcri1eVer, in the casos ~;here i t 'ilas possible to exnmine smaller
groupings, thore ~~s no apparent effect of catch ~ze on selectivit~

Selection runges varied ~rom 8 to 18 cm ....l ith un average value o~ 13 co. '
The selection runses sholl 0. tendency to incrcase '"lith thc extrene ronge o~ mesh

mcsh size is somevrhat more narked. No correlation ,;;as evident between mesh size
und extrenc mesh range.
Selection ~actors ~rom paired and nlternatc hauls are less reliablc duc to
thc marked variation bet'.veen hauls both in length composition und in quuntity
caught, to the smnll nwüber o~ hauls, and also, in thc case of Ä. T. CAMERON at
Skalfandi, to accumuldions of L8Ii1inaria in the cod-end.
Such figures as were
obtained, hmlever, shov: that in this experiment the solection factors from paired
hauls are some•.hat lovrer thm those ~rXl cavered hauls \;hile that from thc
alternate hauls is considerably higher.

Selection ~actors uere Dlso obtaincd ~or the polyamide materials capron
and nylon, the former material being used in cod-ends ~itted both w~th and
\'uthout top-side ch~ers. There is no evidence that thc type o~ chafer used by
GONCHiillOV influenced thc selection of cod. The selection factors ~or the
polyc.rnide materials are higher than the averaße for d'Juble manila,and the
di~~erential calcula ted \n thin ships is close to, but lo',;er than 10;'".
The selection ranges for the synthetic cod-ends also sho~ an increase \vith
both range o~ mesh size and average raesh size,although for these cod-ends mesh
size and mesh range are positively related.
Girth mca::mre:nents of cod at Iceland \lOre takEm on A. T. CAMERON, MARIA
JULIA o.nd EXPLORER. (Tablc 6~) It appears that N. lceland cod is, in shape,
intermediate beh;een North Sea (Uargetts, 1957) and Arctic cod (1959 International
Arctic trav;l mesh experiments; IOES, 1963). There appears to be no substantial
cod sho.pe dif~erences bet\ieen N. Icelund fishing grounds such as to affect
selcction. The regressions of girth on length are similar, so a comparison of
girths can conveniently be made at on arbitarily chosen length, in this case
50 cn as being near thc 50/0 lcngths in Arctic and Iceland eJ.'})eriments. There
'\lere di~~ercnces behreen th:3 vexiouß nhipG' ;;irth oeuliurew.ents botb at lceland
and in thc Arctic, but it is seen tüat the t~u independent measurements at
Iceland both give a head girth oeasurement at .lcngth 50 cn (23.7 and 24.0 cm) ,
ap~reciably greater than the biggest Arctic reeasurements (21.8,21.2 and 23.1
cm) und about 2 CL'l ßrcater than thc mean of thc Arctic neasureraents. Thc maximum
boay girth at length 50 CD. measured at Iceland (24.0 and 26.2 cm) v,as similar
t 0, or rathcr bigger than, thc cOLlparable Arctic measurements' (22.6., 23.8 and
25.0 cu). Thc moxil'!lUl:J. body girth dcaSUreltent is affected by such as ~eeding
and "blov.n" condition, but it is t~le only onc available for cor.a.parison of North
Sea and Iceland cod, and, as such, shOViS North Sea cod llcasured on an English
ship to have about the Sm1C girth as lceland cod rneasured on A. T. GAMERON and
MiffiIA JULIA.
The ~oregoing re3ults are all ~ram hauls made o~~ thc north coast of
Iceland in the sUrJ,.t:ler. Diff'erences in shape und condition of cod between north
und south Iceland are lma.-.n to exist, the ~ish in the south generally being
thicker, length ~or length, than th')sc in the north. It \7ould accordingly be
expected that selectivity in the south 'ivould be lov:er than in the north.
Seasrnal diff'erences ,rithin the northern area are unlikely to ~f'ect selectivity
appreciably.
The mean of all the Arctic cod covcred double manila tra~l cod-end mesh
selection factors ~rorü the leES
Mesh Selecticn -;;;orking Group report was 3.5.
(Note: that report considers that, allo\nng for cover effects und catch size,
the true faetor might be 3.7). The comparable factors for North Sea und
Iceland cod, both frorn linitcd expe:dLlentDl evidence) ,...e re both 3.4; thc new
evidence ~ror..J. 1962 indicates 0. selection ~actor for Icelund o~ 3.2 v.hich is 8.5ro
bolow the Arctic factor ",hila thc hend girth at Icelund "v\"::l.n 91'0 greater than in
the Arctic. Body girth neasurcucnts sugßest that the North Sen. cod selection
f'actor should·be about the SDJn0 as thc lceland factor; such.liraited experimental
evidenee as exists indieates it to bc rather higher, but the differenee eould
...., rell be due to experirJ3ntal variation.
2. Haddoek. The data yielded sixteen·estinates of tho seleetion faetor for
eovored eod-eneis of double uanila ranging from 3.0 to 3.6 vlith an unv:eighted
average of.3.35. These results eeme froI4l hauls taken both off thc north and off the
south eoast of Ieeland and no signi:fieant diffcrences y;ere found between these
two areas. The data i"lerc not sufficient to analyse the relationship between
eateh size and selection faetor. The average scleetion faetor is higher than
that of 3.2 cp.lculatod fron previously available data for the Ieelandie area and
also higher than those for all other lCES are'lS for ',';hieh data are available,
although not very different from that for the .Arctie. (IOES, 196)'.) The reasans
for this differenec are not kno,;n, but thc range of results suggests that at
least not all of the difi'erenee is due to experimental variation in 1962.
The seleetion ranges i'rom the eovered double uanila hauls vary from 4 to 13
em .vi th an average value of 9 er;, of "hieh mo st of· the 10';;er values are e onsidered
doubtful. There is a elear re:lo.tion bet,,'een soleetion range and :nesh size, the
seleetion range inereasing .iLth tho nesh sizc. On thc other hand there is no
relationship between seleetion r~1gc and thc extreue range of oesh sizes in thc
eod-end.
Seleetion fc.ctors for double eapron again
do not show any real evidenee
of an effeet on seleetion laetor of thc top-side ehafer used by GONOHAROV.
_ . EXPLORER data shov: the seleetivity on haddoek of double nylon to be abeut
1<:% higher than that oi' d,-ubl v l.:.mila, but GONOHARCV data indieate no seleetivity
differcnee betwoen these t,,:o ::aaterials on haddcck.
Tho polyamide r:18.terials sho'" a relaticnship between seleetion range and mesh
size similar to that for double manila.
hese materials a relationship is
also found bot,veen seloetion range and extreme range of oesh sizes, the latter
being direetly related to 9.verage fllesh sizc for nylon and eapron.
Girth measur6ments of haddock at Ieeland vrere taken on thr of the ships;
on t ...·,-o of these the maximum body girths were measured and these at total length
50 em (25.6 and 27.7 en) were of the same order as for North Sea haddock (27.2
em, Margetts, 1954). Oorr:.parable Arctie ho.ddock girth measurernents are not
available •
•
3. Redfish. The ealeulated seleetion fo.etors for eavered double r.lanila hauls
range from 2.2 to 3.2. In respeet of this wide vc..riation the present experiment
is in agreement ~~th previous experiments elsev,rhere•.
The results obtained

by ANTON OOHRl{, 'ilhen hauls are grouped aeeorcling to
abave and beloYl 500 kg, indieate la;lCr seleetivity with
tcnd to support the earlier ob~ervaticns (rOES, 1963)
in seleetien fnctor ',.i. th_Düsh size.
Tbe seleetion ranges uere difi'ieult to derivG in most eo.ses,but.reliab1e
estimates indieate a scleetion rmge of about 16 em.
Seleetion faetors obtaincd for eod-cnds oi' polycnide materials lie within
the upper part of the range of seleetion faetors for double nanila. HOV7ever,
..vithin-ship eOclparisons indieate no difi'erenee bety;een polyamide and manil.a. It
is noted that thc seleetion faetors greater than 3.0 were 0.11 obtained from the
areo. S~l Ieeland .:hile the vo.lues lower than this ..yore obtained from '11 and N
Ieeland, but this eould \7ell be an experimental effeet.
Redfish neshcd in the eod-end were reeorded s.uparately on ANTCN DOHRl"i and
GONOHAROV. In ANTOn DCHRN hnuls, appreeiable Llcshing (more than 5% meshed at any
. eentinetre length) \~-as eonfined to 0. length range extending over 12-15 em. On
plotting smoothed pcreentage neshecl against length i t ,;,'o.s seen that, in the ty/o
manila eoel-ends, at any eentimetre length, the meshed proportion oi' the fish held
by the eod-enel rose to about 26~'0 and 1570 respeetively, being above 1 O}~ over a
length range of 6-11 en. In the tvo perlon eod-ends, the proportion meshed
5.
•
reachcd 2C!io und 30}b respectively, and the length range of more than 107o meshed
uas 9 Cffi. In the case of GQ~CIUillOV the meshing size range extended over 20 Cffi.
Ovar 6 cm of this range about 50/" of the fish held by the codend ,1ere meshed,
und .OVer mueh of thc renminder of the range over 20;,,; were meshBd. In the case
of A1~TüN roHRN thc lcngth rnnge where most fish ,rare meshed was in the upper
part of thc trawl eod-end seleetion range ~hile in GONCHAROV it extended over
almost all of thc seleetion range. ANTON DeERN, per haul, caught larger nUl'D.bers
of fish in the selcction range than did GONCII:illOV. The pattern of moshing in
the coel-end -aas simil2..r to that 8f gill-net scleetion.
•
In these Bxperinents a considerable auount of fishing time vas devoted by
A. T. C.AlffiRON and ER1\Tß8T HOLT, and rather less by MARIA JULIA, to neasuring
scleetivity by thc alternate snd paired hüul. tcchnique. By eonsidering hüuls
vii thin ships tho data from all three ships could be trcatcd as for alternüte
hauls; by considering hauls cf A. T. Cl'.l.lERON nnd EBNEST HOLT together they eould
be treated as for paired hauls since it was arrangcd that y,hile one ship ,ms
uuing big mesh the other was using siOall mesh. Yct the results achieved were
some of the least satisfaetory in aseries of experiments ••hieh yielded quite a
lot of rather uneertnin results. The fundauental reason for this -i;as that thc
length distribution und qUillltities of fish from place to place at quite short
distnnees and even on one ground betveen different times varied very markedly•
This mcant that the alternate hauls \'"lere almost useless Ylhile thc paired hauls .
vvere rather bettcr yet to give elear resul ts needed lilany more hauls than ....ere
possible. Plotting of seleetion curves and interpretation of cven approximate
50}v points 'lIas so unsure that it W3.S thought best not to inelude suggested
results trou altern?.te k..uls. in the report tuble.
A i'cature oi' tha s01oetion curves plotted for the Iceland mesh experiments,
and one also cf the Barents Sea seleetion eurves earlier (IOES, 1963), was that
vcry frequcntly they did not smoothly approach thc zero ret:rined level, but
rather thore was a band 01' Ci::l lengths vhcre thc pereentc.ge rctained 1,vould have
been expectod to be ncar zero but ,,/here i t lias in fact around the 25~'o retained
level. This may bo a ma.sking effeet, but due not so Dueh to thc cover as' to
other fish in the cateh. It ,;ould therefore be expectcd to bc areal occurrence
rather than an experimental c.rtefact.
