1. Intr oduction
During th e last decades healthy eating habitshave re ceive d increase d at tentio n, and it is widelyre cognised that regular fish cons um ption is onepossible health im proving practice (HogeGe zon dh eidsra ad ,2 0 0 4 ;Sidhu,2003). However, actual fish consumption generallynot eve ncom escloseto the reco mmenda tions to ea t fis htwice a week in m any European countries (Scie ntificAdvisory Committee on Nutrition, 200 4;W elch et al . ,2002) .

A con sid erab le am ou nt of re se arch has sh ed lighton consumers ’ m o tiv es and barriers to fishconsu m ption. Research has espe cially focused onthe relationship between consumption of fish/seafood and attitudes (Brunsø, 2003; Leek,Maddock, & Foxall, 2 0 0 0 ;Letarte,Dube´, & Troche,199 7; Olsen, 200 1; Olsen, 2003), an d the im pact of consumerinvolvement ( Juhl & Pou lsen , 2000 ;Olsen,2 0 0 1 ; Olsen, 2003), role of l ifestyles (Myrland, Tro ndsen, Johnsto n,& Lund , 2000), experie nc e a ndhabit (Myrland et al., 2000; Tro nd se n,Braaten,Lund, &Eggen,2 0 0 4 ; Trondse n,Scho lderer, Lund ,& Eggen, 200 3;Honka-ne n,O lsen, & Verplanken,2005), socio-dem og raphicchar-acte ristics (Myrland et al., 2000; O ls en, 2 003 ; Trondsen

In co ntrast, re la tively fewstudies have focused on co nsu m ers’ fish qualitype rception and quality evaluation, with a fewexceptions. In on e stud y by Nielsen, Sørensen, andG ru nert (1 997), a qualitative approa chw as applied tode rivequality dim ension s of im portanc eto con- sum ers,reve aling that de sired qu ality dim ensions are es pe -ciallylinked to he alth and family w ell-bein g, thu s re lat ingtothe pe rson alre lev ance of fish quality.In anotherstudyon co nsu m ers’ quality eva luation , it was found thatmany consumers fee l un ab leto use att rib utes of freshfish to eval- uate the ove rall ex pe cted qual ity ( Juhl &Poulsen, 2000) . Also consumer in teres t for additionalinformation and use of information sources hasonly scarcely been researched with respectto fish(P ieniak, Verbeke , Fruens -gard,Brunsø, & Olsen,2004) . The pre sen tpap er aim sat bridging part of th is ga pin understanding consu m ers’ quality evaluations of fish, thr ou ghfocusing on tw o sp ec ificarea sof consumerevalu-ation of fish quality and their associations withconsumerbeh aviour towards fish. Since m any studiesa lready concen- tratedon the precursors of qualityandqualityperc eptions,w e do not intend to focus on whatfish quality means to specific peop le in this s tudy .Ins tead, w e w ill arg uetha tpe r-son al im portanc ea tta chedto fis h quality , and consumers’se lf-confide nc eto assessfish qua li ty , a re two re levant con- cepts in the qualityevaluation pro ce ss. It is argued that these twodim ension s influence several steps in th e deci- sio n-mak ing processof fish con sumption, and are ass oci-ated with individual and soc io-dem og raphic fa ctors . The fol lowing section introduces the constructs andth e rela- tions tha t will be inve stigated in this stu dy.Ne xt, m ate rialsan d m ethods are de ta iled ,followed by theprese ntat ionand dis cussio n of the em pirical res ults.
2. Theoretical approach to study consumer evaluationof fish quality
2.1. Dimensions in quality evaluation
F irst , consumers may differ with respectto qualitycon- sc iousnes s,or pers on alrelevanc ea ttache dto q ua lity.Qual- ity conscio usne ss or re le vance is defined as ‘‘amental predispositionto re spond in a consistentway toquality- related aspects which is organised throughlear ning and which influences behaviour” (Steenkamp,1989). Consum- ers wh o are m oreconce rne dwith prod uctquality are likely to have a hig he ru tility, i.e. a higherva luation , for quality products tha n co nsum ers who areunconcernedabout qual- ity. The conceptof subjectivesenseof co ncern toward s an object, or importance orperson al relevance is closely relatedto involvement(Zaichkowsky , 1985), which is also defined as amotivational stateof mind with regardto an objectoractivity (Mittal & Lee, 1989). In this sense, higherinvolveme nt or pers ona lrelevan ceattach edto quality,may im pact on quality eva luation an d its ou tcom es intermsof
de cision-m ak ing . As a result, involvem en t withquality, wh ich refers to im portanc e attache d to qualityor quality consciousness is th e first hypothesisedd im ension of fish qualityevaluation.Secon d, con su m ers often e xp erie nc e q ualityuncertaintybec aus equ ality performa nce, including thetaste sensation and qualityexperienceafter cookingandconsum ption, is difficult to predict based on productch aracter istic s avail- able in the purchas ing situation(Gr un ert, 19 97). Consum- ers face difficulties ineva luating quality, in particular for un branded andhighly perishable food productslike fresh fish ( Juhl &Po ulsen , 20 00). Furthermo re , c onsum ers differ in theirperceptual ab ilities , co gn itive capacities, pe rso na lprefe rences, and ex pe rience level, and therefore,theireval- uation and perception of quality may vary
accordingly (Ophuis & Van Trijp, 1995). In re sponse touncertaintyand lim ited ab ilities , they form qualityexpectationsthrou ghma kinginferencesby using cue sorpiecesof infor- mation.One of the ba sic driv ers of in fe rence-m aking per- tains to con fidence in cueutilisation (C ox , 1 9 62), or also co nfid ence in th eperson alability to m ake inferencesb ased onparticularcues(G ru nert, 2005a). Hence,se lf-confidencein makingan evaluation of fish quality is hy pothes ised toco nst itute a second dimension in fish qualityevaluation.Individual differences in quality eva luationshave nu m ero usconsequ en ce s,e.g.in terms of behaviour,beliefsor at titud es, and se archfor an d us eof in form ationsources dur ing decision-making, since expected qualityinfluence s a who le range of attitudes an d behav ioursfrom me al prepa -ration methods to future pu rchasedeci sions (Brunsø, Fjord, & Grunert, 2 0 0 2 ;Grunert,Hartvig Larsen,Madsen,
& Ba adsgaard ,1996) .
2.2. Association with behaviour and beliefs
Co nsume rs who lack the confide nc e in ass essin gfish quality – because of for exa m ple, limitedexperience or low perce ptual ab ility – are expect edto actdiff ere ntly dur- ing the decision-making processcomparedto knowledge-able, se lf-confiden t con su m ers.Both product expert ise( i.e . t he ability to performproduct-re la te d t ask s success- fu lly ) and p ro duc tfamiliarity (i.e . the num ber of product- relatedexperiences) are hy pothe sise d to associate withconsumers’ confidence in as sessing pro duct quality, aswell as w ith inv olvement with qua lity.W e expe ctthatconsum-ers who have lim ited co nfidence in assessingfish quality ( i.e. consumers facing high er levels of uncertainty) and/or low er involvement with fishquality, will be less familiar with fish and less inclinedto buy fish.
Lower experience and lower confidence are likelyto asso cia tealso w ith the pe rc eived risk of buyinglowquality or makinga wrongchoicewhenbuying fish,aswell as with fish be nefit percep tion .He nc e, also high errisk perc eption and a more critical attitude towardshealth benefits can be expected amongconsum ers whoare less invo lved and feel less confident aboutev aluating fish quality. Thus, a consumerwho feelsmore confident in judgingfish quality,

can display a m ore favou rable attitude and a higherfish con sum ption pattern as s/he is re latively su re of buying high quality, henc e,at leastthe potential barrierof quality uncertainty is lifted.
2.3. Association with information variables
Co ns umers who fin d qu ality very imp ortant, or whoare h ig hly in vo lved with quality, and/or feel moreco nfi dent in eva luating q uality,m ay hand le information
differentlyas compared to consumers who are morecasual to wards quality.First, pre vious rese arch has also de m onstrated thatprior product kno wled ge or familiaritywith the produ ctinflu- encesthe extentto which consum ers sea rch for,recall and us e inform at ion in jud gem en ts of productquality and in product choice (e.g. Bettman , Lu ce,& Payne ,1 9 9 8 ;Howard & Sheth, 1969;Rao & Monroe, 1988) .Increased famil iar i ty leads to bet ter-d evelop edknowledgestructures or associative ne tworks ab ou t aproduct that tr igger the use of spe cific eva luativecr ite ria and ru les for product assessm ents. Co nsequently,dep ending on familiar- ity with the product (and henc ehavingmoreor lessconfi- de nce), consum er sdiff ere dinth eir u se of information in pro duct ev alua tion ingeneral(Park & Lessig, 1981). Spe- cific ally, both thetype of information cues used, and the number andrelative impo rtance attached to information sourcesdiffered by th e level of produ ct -specific buyingexperience (Kline & Wagner , 1994). As se lf-confide nc ein quality evaluation is expected to be ass oc iatedwithcon- su m ers’ prod uct ex pertise ,w e expect that the lev elof se lf- co nfiden ce will also influence the use of informationso urce san d inform ation cu es .
Se cond, a m ultitude of rese arch ha s fo cu ssed on therela- tionship be tween se arched or used informationcues and expected or experien ced qu ality. Brandname and price are often consid ere d as ind icationsof product quality (Boulding& Kirmani, 1993;Dodds,Monroe, & Grewal,1991). Pre vious rese arch co nc lud ed that the use of
specificqual ity cues associates with product experience(Bredahl ,2 0 0 3 ;R ao & Monroe, 1988) , product interest orknowledge(Sa wyer, Wo rthing , & Sendak , 197 9;Ze ithaml, 1988)andperceived decision d ifficulty (Lambert, 1 972;Pechm ann&
Ra tnesh w ar, 19 92 ;Saw ye ret al., 19 79 ;Zeitham l, 1988) .In othe r wo rds, consum ers wh o find it hard toevaluate ,
for exam ple, product quality, are likely to usedifferentat tr ibutes to ba se the irpurcha se de cision on comparedtocon sum ers wh o can easily assess product qua lity. Asindi-cated befo re,w hether a consumerwill use a qualitycuedep ends on the predictive value of th e cue and th econfi-d en ce th e c on su m e r h as in h is /her ab ility tocomprehendth e cu e co rre ctly (C ox , 1 96 2; S te enk amp, 1990).Differentc ue s e m e rge when persona l ability (and hence self-confi-dence) to judge pro duc t quality differs. Es pe ciallywhenco nsum ers ca nnot ju dg e qu ality , b ran d n am esfrequentlyemerge as an imp ortan t ev alu ative crite rion or as asurro-gate indicator of quality (Boulding & Kirmani,1993) .
An individual w ho does no t atta ch gre at im portanc eto qual i ty,may base his/herdecisionon attr ibutes likeprice, ex pirydate and conven ien ce(pr ep aration) an d m ayuse less inform ation cues, w hile the ap pe arance of th efish, control certificate or th e po ss ible p rese nceof harmful ingredients (in trinsic /credence attr ibutes ) canbe more important to the con sum ers perceiving qualityand their abil ity to evalu - ate qu ality as im portant.Furtherm ore,con sum ers wh o feel lessconfident in ratingfish quali ty can be more prone to use con trolce rtifica tes or us e fam ilia r , knowledgeab le ortrustworthy sources (e.g. friend s, fam ily, fish m onger ) ascomparedto the m ore self-confid entconsum er. In thespe-cific caseof freshfish, a relevant question pe rtain sto th e potential of quality lab els as an informa tioncue, and whether quality labels could perform afunction similar to bra nds, i.e. alleviatin g low self-confidence .
2.4. Association with demographics, individual’s food
involvement and food-health awareness
Finally, we propose th at the tw o hypoth esisedcompo- nents of quality eva luation – involvementwith quality and self-confi den cein quality assessme nt–are as so ciate d w ith ind ividual characterist ics , such associo-demograph- ics, cognitive and motivationalvariables.Previous research ind icated that personalattribute imp ortance – resultingfrom its instrumentality– is am ong sto thers related to a consumer’s socio-demographic profile, kn owledge and involvement(En gel, B lackwell , & Miniard, 1995). Conse- quently,consumerswho atta ch d iffe rent im portance to qualityin a food con text could also diffe r in their individualcha racteristics. Rele van tindividual characteristics arefor instan cesocio-demographic chara cteristics, as we ll asindi- vid ual’s invo lvement with food in gen eral, andindividual’s awarenessof the rela tionship bet w eenfood and health, wh ich are quite relevant in th especific case of fish that has a predominantly healthyimage(Nielsen et al., 1997) . Also a consumer’s self-confidencein eva luating quality can be re lated toind ividual charac ter istic s. Sp ec ific ally, prod uc texp ertisean d fam iliar ity havebeendem onstratedto be re lated toindividual d ifferences in so cio-demographic profile,involvement(Celsi & Olson, 1988) and product- specifickn owledg e (Park & Lessig, 1981) .
2.5. Research objectives
Throug h this rese arch, we first aim at va lidating th etwo hypothesised dim ension s in relation to fish qualityevalua- tion,i.e. involvem en tw ith fish qua lity and se lf-confidencedu ring pro duct e va luation. Se cond, we aimatsegmenting consumers based on their fish qualityevaluation profile and to an alyse individ ua ldifferences that determine or ex pla in consum erdecision-making in generaland informa- tion searchregarding fish in particular. The rationale for startingfro m qu ality ev alu ation -based se gmenta tion is that th ehypothesised quality dim ension s can potentia lly bealtered through appropriate co m m unica tion.Brunsø

Respondents w ere e ither se lectedth ro ughadoor-by-door random walk procedure or atsupermarkets. All respon- dentswere responsible forfood pu rchasin g within their household. They werecheckedagainst the age quotaand asked for theirparticipation in the surv ey . The question- na ire w a sfully self -a dministered. The total sample consisted of 429 respondents, 284women and 1 45 m en .

3.2. Measurement of constructs
First, eight items pertaining to fish qualityevaluation were p resented and scored on fiv e-pointinterval scales ranging from ‘‘totally disagre e” to‘‘totally agree”. Four item spert ained to the perceivedim portan ce of fish quality and makinga good decisionwhen evaluat ingfish quality, wh ere asthe othe r fouritemspertained to the self in rela- tion to fish qualityevalua tio n ,i.e . the pe rc eive d difficulty or uncertaintyinm ak ingfish quality evaluations.
Second, total fish consu m ption and co ns um ption of fresh and processed (d ried , sa lte d or smoked) fishw eremeasured on a seven-point frequency scale rangingfrom‘‘daily” to ‘‘never”. In add itio n , w e a sked o u rrespondentsho w m an ytimes (ou t of ten) fishis chose n w he nv isitingarestaurant. Furthermore, we confronted our
respondentswith 10 fish species and asked if th ey ev er cons u m edthese(yes/no). The choice of species w as ba se d onconsumerp an e l d ata for fis h con su m ption in Belgium (GfK ,2003) ,with cod, salmon, and tuna being considered ascommonlyknown and frequently consumed fish spec ies;her ring ,m ac kerel , and sardines as processed fish species,which
are usu ally canned or marinated; and sole, turbot,brilland angle r as more exclusive fish species that aremoreexpensive and/or require specific cooking skills. The

5. Discussion and conclusions
Resu lts rev ea l t ha t fish qualit y eva lua tio n ismultidimen- sio nal, in tegra tin g the perceive d im portanceof fish quality
are by far the least involved w ith fish qu ality , w hichlogi- cally results in (or f ro m ) lo w es t in te rest ininformation. Raising th eir in volvement with fishquality, for instance throu gh stressing pers ona lh ealthbenefitsfrom fish con- sumption, emerges as th e m ostchallenging co m m unication strategyfor this particularse gment. Sinc elow involvem en tusually associates withless exte nsive decision-making (Engel et al., 19 95),providing too many rational informa- tio n (cognitiv eargumenta tio n)is at ris k of low eff ect ivenessamongthisse gm ent. Instead, aff ec tive arg uments relating topersonal health may stand a be tter ch an ce with th eUn inv olved fish consu m ersegment.Whereas Uncertain fish consumers do not differfrom the Uninvolved in terms of risk and benefitbeliefs and f resh fish consumptio n , t hey do withrespectto fish con- sumption at restauran ts. Clearly,Uncertain consumers , who are relatively h ighlyinvolved with fish quality, put trust in a third partylike an experiencedchef in a restau-rant,more than inthe ir own purchasing, cooking and fish qualityevaluation skills. In a similar vein, Unc ertain fishconsumers display a strong interest in a fish qualitylabel and display co ns iderable interest in bothcredence and search information c ue s. A pp arently,they a re p ro ne to pu t trus t in other people orinstitutions,and would rega rda fish qu al ity label as ausefultoken of product quality, whichis in line withpre viou sstudies by for instance Shap- iro (1983) ,Raoand Bergen (1 992), Dodds et al. (1991) ,Boulding and
Kirmani (1993)and Bred ah l (20 03). The Uncertainfishconsum ersalso ten d to makemoreuseof marketingorcom m ercial inform ation sour ces abou t fish quality.With this profile, the Unc ertain fish consumersconstitute the most interest ing segment for fishquality labelling and information provision fromtrustwor thy or credible information sourc es. It shouldbe noted also that this segment is the larg est of th esa m ple, ac co unting for m ore tha n one third of the fishconsumers. This segment disp lay ssom e parallelsw ith these gment of ‘co nc er ned con- sumers’in the me atm arketas iden tified by Verb eke and

These co nsum ers strongly red uc edme atconsumption as a consequenceof m eat safetycr ises,prob- ably shifted to fish, but f ee l unce rtain withrespectto th e ev alu ation of fish quality. This was a l s oth e segment that wa s expected to show the stro ngestinterest in meat labels an d strongest belief in m eattraceability.Se lf-confiden t fish consumers and fish

Ap parently, se lf-con fidencecom-bined with lower invo lvement (as compared toconnois-seurs) leads to lowe r in te rest in credenceinformation,in cluding lower in terest in a fish qua lity label. Thesegmentof Se lf-confide nt fish consumers inc ludes m o reyoungerconsumers,w ho are either convincedthat fish has ahighen ough qu ality stand ard, or who associate qualitymore
st ro ngly with experience attr ib utes like convenienceandtaste. Fish Connoisseurs are open to moreinformation,es pecial ly of the creden cetype. They also display thestron-ge st interest in a fish qual ity label, despite their highper-sonal confidence in eva luating fish quality. Sincequalityis all too im portan t for fish connoisseurs, anyadditionalinformation signalling product quality, e.g . through aqual-ity label, is warmly we lcom ed. This corro boratesGrunert,Bre dahl, and Brunso (2 004)who indicated that labelsarem ostly asso ciated with highe r qua lity. The stronginterestin quality lab els fits with fish Co nnoisseu rs’ hig hinvolve-m en tp rofile, both to fish and food in general,which ispro-ve n ag ain to asso ciate w ith more op enne ssan d re ad iness
toprocess information, in line with the involve m en t –knowl-
edge assoc ia tion as set forth by Park and Moon(2003).Finally, it should be noted that both th e Self-co nfi dentand Con noisseu rs disp lay the high est belief in healthbene-
fits fro m fish consu m pt ion, though the score around3.4–3.5 de fin itely leaves som e room for furtherimprovementthrough appropriate comm unicationefforts.
Be side sthe iden tification of re lev an tfis h consu m erseg-
ments based on qua li ty evaluation, this study alsoconfirmsassocia tions between involvem ent defined asper ceive dim portance an d product exp erience an d inte res t in
infor-mation . In this sp ec ifi c ca se of fish, productexperienceassociates with higher involvem ent with quality, andinter-est in qualityinformation.
An other fin din gis that the sm allinc idence of scepticism
in mental ben efits de riving from fis h co ns um ption and–more importantly – risk pe rception do not differ
betweense gments tha t diff er stro ngly with resp ect to fishconsump-tion. This is indicative tha t disb eliefs and riskperc eptions
are no t reg arded as m ajor ba rrier s to eatingfish.
Furthermore, this study reveals some relev ant issueswith
respec t to credence qu alities of fish , an d fis h qu alitylabelingin pa rticular. W hereas previous research indicated thatcon-sumers in general attach increasing importance tocredence

qualities (W andel & B ugge, 19 97), and sometimes e venequal importanc e to credenc e an d search qu alities(Bernue´s , Olai- zola, & Corcoran, 2003), we mustconclude that this does not necessarily hold in th especific case of fish. Interest in cre- dence attribute s isranked substantially lower than interest in searchattributes. The gap betw een interest in search versuscrede nce attributes is highest among consum ers withlow levels of both involvement with quality and personalconfi- dence in evaluating fish qu ality (Uninvolved fis hconsum- ers) . This gap is lowest among fishConnoisseurs. Lower confidence in personal qualityevaluation ability w a s e xpected to resul t in a h igherw illingness to em brace external information ab outquality, e.g . stronger interest in price (Obermiller &W heatly, 1 985; Zeithaml, 1988) or in a quality label (cfr.G runert et a l., 2004). Our study supports this asso-ciation. It also shows that uncertainty aboutevaluating quality assoc iates w ith a stro nger interest incredence quali- ties and quality labels, though onlyin th e c as e w her e involvem ent with quality issufficiently high, namely for the Un certain fishco nsum ers but not for th e Uninvolved. Grunert (1997)argued that – in a low involveme ntsituation– consumers m ay ne ver form quality expectations butasso- ciate certain p roduct attributes w ith their dailypurchase sand use th ese to en sure a on e-dimensional, non-specific sat- isfaction with th e purchase a fter consumption. This is clearly the case for the uninvolved fishconsum ers in our study.
This s tudy has demonstrated the usefulness of investi-gating quality e valuation as a two-dim ensiona lconstructthat associateswith behaviour, beliefs andinformation processing re lated to fish . The mainlim itatio n of th e study pertainsto its use of non-probab ility sa m pling and its nar- row geographic focus,i.e. Belgium only, which ranks am ong the lower fishconsu m ption cou ntries in Europe. As a result,genera lisations to the broader national or pan-Eu ropean pop ulation s are specu lative, and it is recom -mendedto va lidate the qu ality ev alu ation dim ensions,th e discovered fish con sum erseg ments and their specificbeh av - iou rsand inte rests th rough cros s-n ationa l, largeran d rep - resentative consum er sam ples. Fu rth ermore,th e issu e of fis h qu alitylab elling and co nsu m erint eres tin fish inform a- tion and related credence attr ibutesdeserves particular attention in fu ture fish consu m erresearch.
