1.3 Introduction

In the ICES Shellfish Committeethere has alwaysshown a manifested interest in squid. Squids areimportant in the fishing economies of several ICESmember nations (e.g., France, Portugal and Spain),several species are cyclically prevalent in the diet ofseveral demersal fish and, in turn, may prey onlarvae and juveniles of economieally-importantdemersal as weil as pelagic fish species. Despitetheir undoubted importance, remarkably little isknown about key aspects of their biology andecology.

At the ICES Symposium on Shellfish Life Historiesand Shellfishery Models in Moncton, Canada (June1990), the Cephalopod section was quite successful,so much so that it led to the initiation of a study ofrecruitment dynamies in the squid genus IlIex. Amember of the Study Group on Squid Biology, EarlDawe (Canada) will be co-editor of a detailedreview of that topic, to be published by FAO.During that symposium Prof. Ronald O'Dor(Chairman of CIAC, the Cephalopod InternationalAdvisory Council, whieh is affiliated to FAO)approached the ICES Shellfish Committee Chairman(Prof. Chris Hopkins) about the possibility ofencouraging more cephalopod research andconsideration of management issues within ICES.

At thc 78th ICES Statutory Meeting in Copenhagenin autumn 1990 the Shellfish Committeerecommended the re-establishment of the StudyGroup on Squid Biology, which the ConsultativeCommittec and the Delegates endorsed. Due to thefragmented knowledge of the biology of Atlanticsquid species, the terms of reference now cover awide range of squid biology. They do not focus onassessment of stocks whieh had been the majorlOpie of former groups. Those were the ICESWorking Group on Assessment of CephalopodStocks (Report as ICES C.~t. 1979/K:3), and theICES Study Group on Squid Assessment (Report asICES C.M. 1988/Assess:l). Both Groupsemphasized in their reports that much more basicknowledge of the biology and Iife cycles ofexploitable cephalopod species is necessary beforeany stock sizes can be estimated.

It is owing to Prof. Hopkins and his particularefforts that this important Study Group wasrevitalized, and that the first meeting of the StudyGroup could take place in Nantes. Furthermore, itis important to mention that, on his initiative, the

2

Shellfish Committee had a special topic on"Cephalopod methodology, biology andmanagement" during the 79th Statutory Meeting inLa Rochelle, where eight contributions oncephalopods were presented.

2 OPENING OF TUE MEETING

The Chairman of the Study Group welcomed theparticipants and expressed his appreciation for theefforts made by thc local organizers of IFREMER,Nantes. The Director of IFREMER, Henrf Durandas well as the French Delegate Alain Maucorps andhis secretary, Beatrix Jego provided an excellentatmosphere for the meeting and helped substantiallyin organizing it. The Chairman further expressedhis conviction that the meeting would not onlycontribute to the scientific work on cephalopods,but also to increased contacts between participantsfrom various ICES nations.

3 ADOPTION OF TUE AGENDA

The Chairman explained the agenda (Annex 2),stressing that a good deal of work has to becompleted in a relatively short period of time. Theagenda was adopted.

4 lr';iRODUCTION OF PARTICIPAl'liS

As astart of thc meeting caeh participant reportedbriet1y upon his recent work in cephalopod science.This was quite an important topic, because manypartieipants did not know each other before themeeting. Some participants introduced their work inmore detail due to their engagement in bigger andlong-term projects.

Eduardo Balgucrias reported on the commercialcephalopod fishery on the Saharan Bank. In the1980s Japan, Korea and Italy were the majornations catching cephalopods in that area. Recently,Morocco and Spainjoined the commerciaI fisheries.In 1990 approximately 100,000 t of cephalopodswere caught in that area, mostly as by-catch in thehottom trawl fishery. The main target species isOctoPIlS vulgaris with 75,600 t in 1990. Otherimportant species are Sepia officinalis, Sepiaelegans, Loligo \'lI/garis and Loligoforbesi. Lengthfrequency data have been recorded for Octopusviligaris, and a length-cohort-analysis was adopted

to the data.

Eve Boucaud-Camou introduced the French workon cuttlcfish (Sepia ojficinalis) fisheries in theEnglish Channcl. One of the main studics consistsoftagging experiments for monitoring the migrationroutes of the population. About 4,000 animals havebeen tagged during the end of the fishing season. Agood number of them could be re-captured after 5-6months. Another project is a detailed study on thetaxonomy and distribution ofthe early life stages ofommastrephid squids in the F10rida Current.Several types could be identified. Additionalinvestigations on their digestive system revailed thatommastrephid larvae al ready show protease activity.

Peter Boyle and Graham Pierce gave areport on theScottish work on the Loligo jorbesi populationsaround Scotland and in adjacent areas of the NorthSea. Squid comprise a substantial by-catch in thecommercial fishery. A new project funded by theEuropean Community's Research Programme in theFisheries Sector (FAR) involves three ICES nations(UK, Portugal and Spain). The primary aim of thatproject is to improve understanding of the basic lifecycle biology of loliginid squid in the North EasternAtlantic area, thereby providing a basis formultinational management of these increasinglyvaluable resources.

Emma Hatfield and Geoff Tingley summarized theirwork on the life history and stock assessment on theSouthwest Atlantic populations of the squids l/lexrgenrinus and Loligo gahi. At present a strongcommercial cephalopod fishery exists around theFalkland Islands. Fishery data since 1985 areavailable for modelling the population dynamics ofthe two species, and management advice has beenprovided for the 1987 and 1988 fishing seasons.However, migration patterns ofthe animals are stillunknown as is information on their early life stages.Emma Hatfield also examined the use of a cohortseparation procedure on female length frequencydata for Loligo gahi for 1985-1990 to identify therecruit broods per year.

5 REPORT OF THE CHAIRMAN

Preparing the meeting consisted mainly ofestablishing contacts with cephalopod workerswithin the ICES area in order to elucidate theirinterest in the Study Group's terms of reference.The response to various circulars was very positive.

3

At present the still-growing Study Group consists of26 members from 11 ICES nations, which clearlydemonstrates the need of such a group. A list of allStudy Group members is attached as Annex 3.

It is important to mention here that many membersare also engaged in other international organizationson squid biology and fisheries. The main events in1991 were the CIAC International Workshop onAgeing, Gro\\1h and Population Structure ofCephalopods and an International Symposium onthe Recent Advances in Cephalopod FisheryBiology which both took place in Japan. Severalmembers of the Study Group participated in thosemeetings. The aims of the Study Group's workwere also introduced to CIAC by an article in oneof the last CIAC Newsletters. FAO was alsoinformed about our work and welcomed that ICESis now giving more attention to cephalopods.

Finally, our Study Group received a message fromDr. Sigurd von Boletzky, who is the coordinator ofthe sister group in the Mediterranean area, theCIESM Working Group on Cephalopods. Heexpressed the wishes for future collaborationbetween the two groups within the greater networkof cephalopod research organizations. A main topiccould evolve in a joint work on the exchange ofcephalopod populations via the Strait of Gibraltar.

6 REPORT ON TUE TERMS OFREFERENCE

This topic included detailed discussions on thevarious terms. The major findings of theparticipants' contributions are summarized below.

a) Basic information on the biology andworldwide distribution of cephalopods thatare of economical importance has beenrevised in an FAO publication (Roper er al.,1984). However, a compilation ofinformation for cephalopod species that areof interest within the ICES area is stilllacking. New data on lire history anddistribution of cephalopod species in theICES area and adjacent waters are currentlycollected for Sepia ojficinalis, Loligojorbesi, Loligo vulgaris, Illex coindetli,Todarodes sagittatus, Gonatus jabricii andOctopus vulgaris. In the present EC fundedEUROSQUID project on the "FisheryPotential of North Eastern Atlantic Squid

b)

Stocks, scientists from Scotland, Portugal,the Azores and Spain are engaged in orderto improve the knowledge of the ecology ofloliginid squid in the whole North EasternAtlantic. The project (see Doe. K: 13) willdemonstrate whether there is a potential forcommercial exploitation of the speciesLoligo jorbesi and Loligo vulgaris.Additionally, French data from the EVHOEsurveys show the squid distribution in theBay of Biscay and the Celtie Sea (poulard1991). Portuguese work focuses on theeephalopod data from Algarve waters andaround the Azores (Does. K: 10; K: 11).Irish data will be obtainable for thedistribution of loliginid squids in Irishwaters. Further data in regions outsidetraditionalICES areas have been reportedfor flying squids in the CECAF area (K:24),for the squid Gonarus jabricii off WestGreenland (K:55) and for the squid fisheriesin the Northwest Atlantie (K:9) and theSouthwest Atlantic (K:48; Martinez er al.,et a1. 1990).

Studies on population parameters arestressed on growth estimates for severalspeeies. Recent Portuguese workinvestigates growth and reproduction of thecuttlefish Sepia ojjicinalis in the RiaFormosa where aquaculture experiments arealso planned. A wealth of information on allaspects of population parameters forEuropean cuttlefish has been published inthe Proceedings Volume of the 1stInternational Symposium on the CuttlefishSepia held at the University of Caen, 1-3June 1989 (Boucaud-Camou 1991). Further,growth studies under experimentalconditions have been carried out for Loligojorbesi by scientists from the University ofthe Azores in Horta in cooperation with theUniversity of Texas. The EUROSQUIDproject will include studies on thepopulation biology of squid, includingfecundity studies and feeding biology ofLoligo jorbesi and Loligo vulgaris. Spanishand Scottish data are available for growthestimations of Octopus vulgaris and Eledonecirrlzosa, respectively. Most growthestimates depend on aquarium studies andpopulation modal analysis. A new method incephalopod science using RNA:proteinratios to determine growth rates of Ocropus

4

e)

is currently applied at the University ofAberdeen. Generally, growth rates ofeephalopods ean be extremely high anddecrease drastically with sexual maturity.

It is obvious that hiologieal andhydrographical faetors are crucial forunderstanding distribution and migration ofcephalopods. Annual recruitment to thestocks depends on each year's breedingsuceess and the survival of the offspring.Particularly the latter is controlled byhydrographie factors like water temperatureand currents. Possibly, sea surfaee satellitetemperature data in comparison withhistorical eatch data could help inunderstanding migration routes and wouldassist in prediction of recruitment success ofthe various stocks. Analysis ofenvironmental data sets in comparison with •Loligo distributions will be a main subjectin the EUROSQUID project. Data for thesestudies will be collected by research vesselsand commercial fishing boats. In aforthcoming FAO publieation on therecruitment dynamics in the squid genusIllex, several members of the Study Groupwill report on the recruitment variability ofsquid in various regions of the AtlanticOcean. French investigations on cuttlefishstocks in the English Channel emphasizethat tidal currents are of major importaneefor the migration routes of the animals. Therecent significant increase of Sepiaojjicinalis in the Celtie Sea as weil as onthe Saharan Bank is yet not fullyunderstood; maybe it is related to a lower •mortality caused by the relatively mildwinters during the last years. It isrecognized that much more attention shouldbe paid to investigations on the coupling ofenvironmental changes and cephalopodstock fluctuations. Besides, it should beemphasized that more imformation fromstudies on the feeding ecology ofcephalopod predators Iike fish, binls and seamammals should be collected. Suchinformation represents the biological faetorsthat may influence recruitment ofcephalopods. Their c10ser examination isessential in modelling the changes ofcephalopod populations.

f)

Sueeessful tagging of eephalopods is onlyaehieved if the eaptured animals are in aperfeet eondition so that a reasonablesurvival rate ean be assumed. For squids,this is only true for jigged animals.However, jigging is only sporadieallyearried out in the ICES area, and at presentthere is no eommercial jigging fishery. We,therefore, eonclude that this technique is notapplieable for the eommercial fisheries onloliginid squids. Further, it has not been asueeessful method in the Canadian Illexfishery, where thousands of animals hadbeen tagged, but only one re-eapture wasreported. Tagging experiments with Octopuvulgaris also revealed no sueeess. The tissueof these animals is too soft to retainordinary anehor tags, and small tag typeslike staples are overlooked by fishermen.The only sueeess was obtained in taggingeuttlefish in the English Channel to monitortheir migration routes. In experiments withvarious tag types, respeetable re-eapturerates eould be aehieved.

The Study Group agreed to delete this pointfrom the terms of referenee, as there arepresently only small loeal fisherics whiehtarget squid. Most landings are by-eatehesin the bottom trawl fisheries. Only a fewgear trials have been earried out so far, andautomatie jigging of loliginid squid aroundthe Azores did not reveal higher cateh rates.

Results from various laboratory experimentsconfirm that there are periodical inerementson the statoliths of eephalopods like thereare on the otoliths of fish. Severalexperiments with a number of squid specieshave validated that these are dailyinerements. Ageing techniques have beenthe subject of an international workshopheld in Mazaro deI Vallo, Italy in Oetober1989. The state-of-the-art of the statolithwork is summarized in the report of theworkshop which will soon appear in aspecial issue of the journal "Vie et Milieu".It is eommonly agreed that the difficultproblem of assessing squid species can onlybe taekled with daily ring ageing. Aceordingto the workshop, however, there areconsiderable restraints that affeet thetechnique: the method is very timeconsuming, validation that rings are daily is

5

not yet confirmed for all important squidspeeies, and a standardization of theterminology describing the statolith structureis laeking. Further, it was emphasized thatalternative methods Iike reading ofmierostruetures on the gladius and on theeye lens could be quite useful in agedetermination, especially when they areapplied in addition to the reading ofstatoliths.

The distrihution patterns of early Iife stagesof cephalopods are extremely difficult todeseribe on the data available today.Reliable data sets on the geographical andvertieal distribution of larval cephalopods donot exist. We strongly recommcnd moredetailed analyses of historieal data sets thatwere collected in conjunction with fishlarvae surveys. There have been a greatnumber of expeditions in the ICES area thatyielded extensive collections of planktondata that have yet not been evaluatedconcerning cephalopod larvae. In theEUROSQUID project older Britishcollections are currently under closerexamination, but we feel that there are stillsubstantial sources in various oceanographicinstitut ions whieh should be investigated inmore detail. Furthermore, there isundoubtedly a demand for specific larvalsurveys in the future to obtain asoundinformation on the distribution patterns ofjuvenile and larval squids that are importantto fisheries.

Identification and separation of cephalopodstocks is investigated in the EUROSQUIDproject by comparing meristic andmorphometric data to study the geographiealvariation in Loligo species. Furthercollaboration with the Liverpool University(Prof. John Thorpe, Dr. Andrew Brierley)is planned on allozyme studies during thecurrent EC-project. Dr. Brierley gave aninteresting talk during the InternationalSymposium on the Recent Advances inCephalopod Biology in Shimizu City, Japan,July 1991 on his biochemical geneticinvestigations of population structure andgenerie interrelationships within the familyLoliginidae. Using the horizontal starch gelelectrophoresis method he dctectedsignificant differences in allele frequencies

Concerning future international projects, thepossibilities of obtaining EC-fundings for jointstudies should be examined. There are stronginterests in UK, Portugal, Germany and Spain toestablish a project that will investigate distributionpatterns of larval and juvenile squids that are ofeconomical importance. It is recognizeJ that thisimportant subject needs astrang collaborationbetween several ICES nations. It could evolve from

In contrast to the former "ICES Working Group onAssessment of Cephalopod Stocks" (Report as ICESC.M. 1979/K:3) and the former "ICES StudyGroup on Squid Assessment" (Report as ICES C.M1988/Assess: I) we give no summary on cephalopodcatch statistics in the ICES area, nor areport onestimates of biomass for the main squid stocks. Asa result of the former groups' \\'ork it had hecomeobvious that much more basic knowledge oncephalopod biology was and is still needed beforeany management advice to the fisheries can begiven. In the present report we have compiled areasonable amount of information that will certainlyincrease this knowledge. However, as reported bythe former groups, for squids, it is not possihle tofollow the normaliCES working group procedureof making an assessment in year n+ 1 on the basisof the data for year n in order to estimate a stocksize in year n+2 on which stock management canbe based. Potentially-exploitable squid species areshort-Iived (as little as 12-15 months), which meansthat the entire catch is Iikely to be taken from asingle recruiting year dass. In regard to this westrongly emphasize the need to document the newmethods for stock assessment that are currently usedfor squid fisheries, and whieh are not analytiealassessments based on age-structure (see Doc. K:9;Beddington er al., 1990; Rosenberg er al., 1990).

d) to report on cephalopod landings within theICES area;

b) to report on the stock assessment methodsthat are used for cephalopod fisheries;

•

•to evaluate prey-predator relations wherecephalopods are involved;

Finally, all participants of the meeting agreed to therecommendation to rename the "Study Group onSquid Biology" into the "Study Group onCephalopod Biology". This would allow theincIusion of the important work on cuttlefish andoctopusses within the ICES area.

All participants agreed to schedule a next meetingof the Study Group directly before the nextStatutory Meeting. This is of great importance dueto logistical and funding reasons. During thesummer months in 1992 a number of cephalopodmeetings will take place, where various members ofthe Study Group will participate. Further, we wantto stress that travel money can be more easilyobtained from national sources if the meeting iscombined with the Statutory Meeting whieh variousmembers of the Study Group will attend. If this isnot feasible we recommend a date in early 1993 fora next meeting of the Study Group.

e) to discuss whether a recommendation shouldbe suggested for a (Mini) Symposium to beheld in 1994 on "Cephalopod Fisheries inthe Atlantic: Past, Present and Future".

a)

c) with special regard to the early life stages,to identify the biologieal and oceanographicfactars which affect the distribution,migration, and recruitment of cephalopods;

Concerning its future work, the present StudyGroup proposed to meet during two daysimmediately before the next Statutory Meeting inRostock with the following terms of reference:

the current EUROSQUID-project whieh will end inDecember 1992. Further, cooperation with thesister group in the Mediterranean area and withAfriea should be considered. On a more globalscale, cooperation with North and South-Americaninstitut ions sounds attractive, especially ifommastrephid squid species are studied whieh aredistributed over wide parts of the Atlantic.

CONCLUSIONS AND RECO~ll\IENDA­

TIONS

at several enzyme loci between Loligojorbesi sampies from the Europeancontinental shelf (Great Britain) and variousAtlantic Islands (Madeira, the Azores). Thismeans a degree of reproductive isolationand the existence of a barrier to gene flowin the Atlantic populations of Loligojorbesi.These new methods in cephalopod sciencewill definitely help to analyse and separatefurther cephalopod stocks within the ICESarea.
