coregonus albula , known as the vendace or as the european cisco , is a species of freshwater whitefish in the family salmonidae .

it is found in lakes in northern europe , especially finland , sweden , russia and estonia , and in some lakes of norway , the united kingdom , northern germany and poland .

it is also found in diluted brackish water in the gulfs of finland and bothnia , both of which are in the baltic sea .

the length of an adult is normally about 20 cm ( 8 in ) .

the maximum age is about ten years .

the vendace is traditionally the most important target of freshwater fisheries in parts of fennoscandia and russia .

vendace roe is considered a delicacy , which has been granted a pdo status in the swedish bothnian bay archipelago ( kalix löjrom ) .

there is confusion over whether or not the true coregonus albula was actually the one imported and stocked in this country . todd ( 1983 ) investigated the history of the early coregonus transfers and summarized much of the information . he was informed by one german contact that the fish imported to the united states from hatcheries on the bodensee / lake constance ( such as the 1885 shipment and possibly others ) were more likely c . wartmanni . kendall ( 1914 ) used the name leucichthys albula for this species .

wheeler ( 1969 ) ; ladiges and vogt ( 1986 ) . the taxonomy and systematics of coregonus is particularly problematic . some of the confusion is the result of the many early introductions and transplants of the various species and populations within europe and elsewhere ( e . g . , leviton 1996 ) . furthermore , the reportedly frequent hybridization between related coregonus species also has contributed to the taxonomic confusion . many ichthyologists ( e . g . , berg 1948 ) have historically recognized only a few widespread , polytypic species of coregonus ( including c . albula ) across europe . recently , kottelat and freyhof ( 2007 ) recognized 59 species of coregonus .

teleost fishes of the coregonidae are good model systems for studying postglacial evolution , adaptive radiation and ecological speciation . of particular interest is whether the repeated occurrence of sympatric species pairs results from in - situ divergence from a single lineage or from multiple invasions of one or more different lineages . here , we analysed the genetic structure of baltic ciscoes ( coregonus albula complex ) , examining 271 individuals from 8 lakes in northern germany using 1244 polymorphic aflp loci . six lakes had only one population of c . albula while the remaining two lakes had c . albula as well as a sympatric species ( c . lucinensis or c . fontanae ) .

while the population genetic data alone can not unambiguously uncover the mode of speciation , our data indicate that multiple lineages may be responsible for the complex patterns typically observed in coregonus . relative differences within and among lakes raises the possibility that multiple lineages may be present in northern germany , thus understanding the postglacial evolution and speciation in the c . albula complex requires a large - scale phylogenetic analysis of several potential founder lineages .

. . . the value of the commercial catch of whitefish from the baltic sea was about 2 million euros in 2005 , and the catch totalled 765 000 kilos . according to the present view , all native scandinavian whitefishes belong to same species , coregonus lavaretus sensu lato ( nikolsky and reshetnikov 1970 ; reshetnikov 1980 ; himberg and lehtonen 1995 ) , rather than the five - species complex based on morphological variation previously proposed by sva¨rdson ( 1957 , 1979 , 1998 ) , although very little genetic research has been carried out on this topic . the only other native coregonid species in finland is the vendace ( coregonus albula ) . . . .

a great number of intra - specific forms of local populations of vendace ( coregonus albula ) are presumed to be a result of hybridisation between different incipient forms . morphological and genetic analysis for the study of vendace population of lake nirza in latvia was used . body length , weight and age in different male and female groups were used for morphological analysis . genetic polymorphism and genetic structure of the vendace population of lake nirza have been evaluated by electrophoresis based on the analysis of isoenzyme systems . four isoenzyme systems ( malic enzyme ( me ) , esterases ( est ) , peroxide dismutase ( sod ) , malate dehydrogenase ( mdh ) ) and non - specific protein were analysed . sixteen polymorphic loci were selected for genotype analysis . the genetic analysis of the vendace population from lake nirza showed that homozygotes dominate over heterozygotes . however , distribution of genotypes among different isoenzyme systems is different . the present study provides the first report on the application of isoenzyme markers for genetic investigations of coregonus albula populations in latvian lakes .

the effects of hybridization and stocking on the commercially important coregonus can be quantified and accounted for , thus the group remains an excellent model for the study of speciation in sympatry . despite having used more than 1200 marker loci in a study of 10 populations , our data failed to provide conclusive evidence for whether spring - spawning coregonus stem from parallel sympatric speciation . parallel trends in niche differentiation and phenotypic differentiation are evident in both lakes with sympatric populations , but neutral genetic differentiation suggests allopatric speciation and introgression on secondary contact . it is clear that population genetic criteria alone cannot resolve the mechanisms of speciation , and that our analysis benefited from a large spatial scale of sampling . examination of relative differences within and among lakes has raised the possibility that multiple lineages may be present in northern germany . as a result , phylogenetic analysis and sampling of additional lakes from potential source populations from a broad geographic range is required for an unequivocal identification of the evolutionary mechanisms and phylogeography which have led to the ecological and genetic diversity found in the c . albula complex .
the objective of this study was to describe the morphometry and motility parameters of vendace ( coregonus albula ) spermatozoa . morphometric parameters of vendace sperm head and tail were of values similar to rainbow trout . the effects of ph , sodium , potassium and calcium ion concentrations on computer - assisted sperm analysis ( casa ) sperm motility characteristics were tested . vendace sperm was motile in a wide ph range of 6 . 0–10 . 5 with the optimum ph established at 9 . 0 . increases in potassium and calcium ions caused decreases in the percentage of motile sperm . the casa parameters and erratic sperm movement pattern of vendace spermatozoa were similar to whitefish ( c . lavaretus ) sperm motility , suggesting that there is a coregonid - specific sperm motility pattern .

. . . both lineages can exhibit dwarf - sized pelagic or larger sized benthic forms , however , when occurring in sympatry individuals belonging to the acadian lineage tend to have evolved towards the dwarf phenotype ( bernatchez & dodson , 1990 ; lu et al . , 2001 ) . also in europe several differentiated forms exist ( himberg & lehtonen , 1995 ; kottelat & freyhof , 2007 ; østbye et al . , 2006 ; østbye et al . , 2005 ) like the north sea houting ( abbreviated nsh ) ( coregonus oxyrhinchus ) , a recently diverged species or ecotype of the european lake whitefish ( abbreviated elw ) ( coregonus lavaretus ) ( hansen et al . , 2008 ; jacobsen et al . , 2012 ) . . . .
vendace have been observed to reduce zooplankton diversity , resulting in smaller zooplankton species and smaller sizes of individual zooplankters ( bøhn and amundsen , 1998 ; amundsen et al . , 2009 ) . they have also led to large reductions in densities of native planktivorous coregonus lavaretus ( bøhn and amundsen , 2001 ; gjelland et al . , 2007 ; bøhn et al . , 2008 ) .

vendace ( c . albula ) is a salmonid fish with native distribution in northern parts of europe . it is an obligate planktivore with characteristics typical for pelagic fish ; a protruded lower jaw and a slender body with black , silvery and white dorsal , lateral , and ventral sides , respectively . another typical pelagic character of vendace is diel vertical migration behaviour . it has an opportunistic life history with many small eggs , high mortality rates , and a relatively short generation time . it is highly specialized , and considered the most specialized zooplanktivorous fish species in the scandinavian freshwater fish fauna by svärdson ( 1976 ) .
. . . the european whitefish species complex ( coregonus lavaretus l . ) illustrates the full range of problems associated with the interpretation of morphological diversity . here , the traditional species designations suggested that numerous whitefish species inhabit european waters ( linnaeus , 1758 ; steinmann , 1950a steinmann , , b , 1951 svä rdson , 1957 svä rdson , , 1998 berg , 1962 ; resethnikov , 1968 ; himberg & lehtonen , 1995 ; kottelat , 1997 ) . however , the phenotypic species classification poses two fundamental problems ( see felsenstein & sober , 1986 ; humphries & parenti , 1999 ) . . . .
arch . hydrobiol . spec . issues advanc . limnol . , vol . 46 , nr . july , 39 - 47 the scientific nomenclature in the systematic literature of coregonid fishes from northwest europe is chaotic despite the application of exact and powerful modern methods in molecular biology and population genetics . altogether over one hundred species have been descriped . there are many parallel scientific names for the same whitefish populations and often old , wrongly used scientific names are still in use . recent advances in research have shown that the number of coregonid fish species in fennoscandia and western europe can be reduced to four species : coregonus lavaretus l . , c . autumnalis pollan thompson , c . albula l . and the introduced c . peled gmelin . the existence of ecologically or morphologically well distinguished sympatic whitefish populations and geographical subspecies motivates a subdivision . the most suitable system is the use of a binominal name followed by a third name descriping an ecological feature , and a fourth name naming the locality of the whitefish populations . the supplementary coding system , well developed , can be useful in fishery management , and it needs a solid background data . the purpose of our paper is to propose a nomenclature and taxonomy for north and west european coregonid fishes hereby provoking further discussion . int . symposium on biology and management of coregonid fishes
. . . the european whitefish coregonus lavaretus ( l . ) is a salmonid widely distributed across the palearctic . the species exhibits great variation in morphology and ecological plasticity , which makes its taxonomy extremely difficult ( svärdson , 1979 ; reshetnikov , 1980 reshetnikov , , 1988 himberg & lehtonen , 1995 ) . virtually all coregonids inhabiting the coastal zone of the baltic sea belong to c . lavaretus sensu lato and include sympatric anadromous and sea - spawning forms ( himberg , 1970 ; lehtonen , 1981 ; amundsen , 1988 ; lehtonen & böhling , 1988 ; himberg & lehtonen , 1995 ; säisä et al . , 2008 ) . . . .
. . . though the use of marine habitats varies , nearly all salmonids spawn exclusively in fresh water , defined as b1 psu ( scott and crossman , 1973 ) , however , exceptions do occur . some european lake whitefish , coregonus lavaretus ( linnaeus , 1758 ) , live entirely within the brackish waters of the baltic sea ( himberg and lehtonen , 1995 ) . pink salmon , oncorhynchus gorbuscha ( walbaum , 1792 ) , and chum salmon , oncorhynchus keta ( walbaum , 1792 ) , are known to spawn in the intertidal zone of prince william sound , alaska ( helle et al . , 1964 ; scott and crossman , 1973 ) demonstrating exclusive marine residency . . . .
. . . coregonus is the most species - rich genus among the salmonid fishes and represents one of the well - known examples of adaptive radiation among fishes ( givnish , 1997 ; bernatchez , 2004 ) . due to high phenotypic diversity , the taxonomy of coregonid fishes has been rather controversial ( berg , 1962 ; sv€ ardson , 1979 ; himberg & lehtonen , 1995 ; reshetnikov , 2004 ) . in european and north american post - glacial lakes , whitefish from the c . lavaretus / clupeaformis species complex frequently occurs in two or more ecotypes that have evolved in sympatry ( bernatchez , 2004 ; østbye et al . , 2005a ; siwertsson et al . , 2010 ; kahilainen et al . , 2011 ) . . . .
. . . the species exhibits great variation in morphology and ecological plasticity , which makes its taxonomy extremely difficult ( svärdson , 1979 ; reshetnikov , 1980 reshetnikov , , 1988 himberg & lehtonen , 1995 ) . virtually all coregonids inhabiting the coastal zone of the baltic sea belong to c . lavaretus sensu lato and include sympatric anadromous and sea - spawning forms ( himberg , 1970 ; lehtonen , 1981 ; amundsen , 1988 ; lehtonen & böhling , 1988 ; himberg & lehtonen , 1995 ; säisä et al . , 2008 ) . coregonus lavaretus has been an important species for both commercial and recreational fisheries in the baltic sea , but during the last halfcentury the natural population has drastically declined , especially in estonian waters ( salojärvi et al . , 1985 ; ojaveer , 1999 ; sõrmus & turovski , 2003 ) . . . .
aflp demonstrated a significant population structure ( bayesian θ b = 0 . 22 ) . lower differentiation between allopatric ( θ b = 0 . 028 ) than sympatric ( 0 . 063 - 0 . 083 ) populations contradicts the hypothesis of a sympatric origin of taxa , and there was little evidence for stocking or ongoing hybridization . genome scans found only three loci that appeared to be under selection in both sympatric population pairs , suggesting a low probability of similar mechanisms of ecological segregation . however , removal of all non - neutral loci decreased the genetic distance between sympatric pairs , suggesting recent adaptive divergence at a few loci . sympatric pairs in the two lakes were genetically distinct from the six other c . albula populations , suggesting introgression from another lineage may have influenced these two lakes . this was supported by an analysis of isolation - by - distance , where the drift - gene flow equilibrium observed among allopatric populations was disrupted when the sympatric pairs were included .
the genetic analysis is made on the population of the european smelt osmerus eperlanus occasionally introduced to lake syamozero ( karelia ) and of the vendace coregous albula supposedly acclimatized in solovetskie islands as a result of fish cultural activities of the solovetskii monastery . they are compared with several natural populations—possible donors for both introductions . genetic variation in a sample of smelt was estimated by means of restrictase analysis of mtdna ( fragment nd1 / nd2 ) in samples of vendace—by means of allozyme analysis of six isoenzyme systems . the probable population for the syamozero smelt is the population of onega lake in spite of the previously noted greater morphological similarity of colonizers with the smelt of ladoga lake . a high level of genetic variation in the syamozero smelt in comparison with native populations indicates that , beside the introduction from onega lake , there were repeated introductions from neighboring water bodies . the genetic analysis of the solovetskaya vendace does not prove that the vendace appeared on islands due to acclimatization . frequencies of alleles of allozyme loci in the solovetskaya population significantly differ from frequencies in continental populations . still , it is compared with some populations of the arkhangelsk oblast . estimations of genetic diversity of the solovetskaya vendace turned out to be comparable with those in native populations .

appearance : a small , slim , streamlined fish most easily confused with bleak or with small whitefish or peled . unlike the bleak , the vendace is a member of the salmon family and thus has an adipose fin . distinguished from the whitefish and peled by its much longer lower jaw . in the whitefish the upper jaw is longer and in the peled the jaws are of equal length .
colouring : back dark bluish green or brownish , sides silvery and belly white .
reproduction : spawns in october - november , sometimes in shallows sometimes in water up to 20 m deep , depending on the lake . some lakes have populations that spawn in early spring in deeper water than autumn - spawning vendace in the same lake . spawns at a young age , usually two years , sometimes in the autumn of its first year .
food : plankton , older fish also take surface insects and small fish fry .
distribution and habitat : originally a fish of the large lakes of se finland , vendace have been transplanted for purposes of commercial exploitation throughout finland with the exception of northernmost lapland , although populations have been established in lake inarinjärvi and the river paatsjoki . does not tolerate brackish water well and in the sea is restricted to the eastern gulf of finland and the northernmost gulf of botnia . vendace move in shoals in open water , preferring deep , clear water . can tolerate more eutrophic waters provided oxygen levels are good .

in britain the vendace occurs only as non - migratory freshwater populations , but in the baltic it occurs as anadromous populations ( they spend most of their time in saltwater and migrate to freshwater to spawn ) ( 7 ) . the vendace feeds primarily on free - swimming organisms such as water fleas ( 6 ) and planktonic crustaceans ( 5 ) .
spawning occurs in november and december ( 6 ) ; adults move to the edges of lakes , and females scatter the small two millimetre diameter yellow to orange eggs in gravely areas in still water ( 6 ) . the eggs are fertilised externally and develop slowly on the bottom of the lake ( 7 ) , hatching the following spring ( 2 ) . individuals are thought to live up to six years of age ( 2 ) .
found in north - west europe between the english lake district in the east to western russia , and from a northern extreme in scandinavia to north western russia reaching south to bavaria ( 2 ) . historically the vendace has been recorded from just four uk lakes ; two in scotland ( 3 ) , and two in the english lake district ( 8 ) . one of the scottish populations has not been recorded since 1911 when a sewage works was built ; the other scottish population has not been recorded since the 1970s ( 9 ) and so the species is classed as extinct in scotland ( 10 ) .
you can view distribution information for this species at the national biodiversity network atlas .
occurs in open water shoals in deep , cold lakes where the vendace can take refuge from hot summer temperatures ( 2 ) ( 6 ) . it also requires shallow areas with a gravely substrate for spawning ( 7 ) .
the vendace is classified as least concern ( lc ) on the iucn red list ( 1 ) , annex iii of the bern convention , annex v of the ec habitats and species directive , schedule 5 of the wildlife and countryside act 1981 ( 3 ) , and schedule 3 of the conservation regulations 1994 ( 4 ) .
the vendace has faced pressure from the introduction of non - indigenous fish species , which were probably introduced by pike anglers using live bait ( 2 ) . juvenile roach compete for planktonic food with vendace , and ruffe eat vendace eggs ( 2 ) . ruffe were recorded in derwent water for the first time in 2001 ( 11 ) . other threats are habitat loss and pollution , particularly eutrophication resulting from nutrient enrichment ( 3 ) , and siltation of spawning sites with organic matter ( 9 ) . the a66 passes close to bassenthwaite lake ; an accident involving an industrial tanker would be devastating ( 2 ) .
the vendace is fully protected under the wildlife and countryside act ( 1981 ) , and both lakes are sites of special scientific interest ( sssis ) and candidate special areas of conservation ( 2 ) . bassenthwaite lake is also a national nature reserve managed by the national trust . the management plan for this site takes into account the presence of vendace ( 3 ) . a current conservation measure involves hatching vendace eggs from bassenthwaite lake in captivity and releasing the young back into the lake ( 11 ) . in addition , young vendace from bassenthwaite and derwent water have been released into two scottish water bodies . a survey of water bodies in cumbria aimed to detect suitable places for the establishment of refuge populations , however no suitable sites were found ( 11 ) .
the vendace is a priority species under the uk biodiversity action plan ( uk bap ) ; the species action plan aims to maintain the current populations and re - introduce the species to scotland by 2005 ( 3 ) .

vendace have been introduced into non - native lake systems in many countries , and in some of them changes within the colonizer population have been studied . however , scientific studies of the effects of vendace invasion on the receiving ecosystem are limited to the inari - pasvik watercourse in the border area between russia , finland and norway . research here has examined effects on the resource level ( bøhn and amundsen , 1998 ; amundsen et al . , 2009 ) , effects from exploitative competition ( bøhn and amundsen , 2001 , 2004 ; gjelland et al . , 2007 ; bøhn et al . , 2008 ) , as prey for piscivorous predators ( jensen et al . , 2008 ) , and experiments using brown trout stocking as an agent for biological control of vendace ( k . ø . gjelland , norwegian institute for nature research , in prep . ) .
strong effects from the vendace planktivory have been reported as reduced zooplankton diversity , reduced individual zooplankter size , and reduced zooplankton densities . this has resulted in lowered zooplankton availability for planktivorous fish , and to a large extent displaced native planktivores from the pelagic fish communities through exploitative competition . due to its relatively small size , vendace is an attractive prey and an important food source for pelagic piscivores . vendace have been purposely introduced to a wide range of lakes and reservoirs .
studies of changes in the invading vendace population come from many different lake systems , e . g . lake osensjøen , southern norway (
some authors recognize coregonids as a distinct family ( coregonidae ) , classified as a sister family to salmonidae ( e . g .
) . the complexity of phenotypic and genotypic variation within the coregonids poses a challenge to the coregonid nomenclature . distinguishing between
the back of the vendace is dark green / blue / black , flanks silvery white , belly whitish , tip of snout and lower jaw black . body is slender when small , moderately slender with increasing size , head relatively small , lower jaw projects beyond tip of snout , upper jaw reaches back to level of pupil , tip of lower jaw fits into a groove in the upper jaw . gillrakers 45 - 52 . pre - dorsal distance greater than distance from dorsal origin to base of last anal finray ; dorsal finrays iii - iv 8 - 9 , anal finrays iii - iv 10 - 12 ( 13 ) . scales moderate , 77 - 85 ( 86 , 88 ) in lateral line . vertebrae 57 - 59 ( 60 ) ( kottelat and freyhof , 2008 ) .
vendace matures within the second to fifth years of life , at lengths 9 - 20 cm . in most populations , vendace rarely attain lengths > 25 cm (
the native range of vendace is within drainages connected with the north and baltic sea , between the british isles in the west and the petchora drainage ( russia ) in the east ( svetovidov , 1984 ; groot , 1990 ; reshetnikov , 2003 ; kottelat and freyhof , 2007 , 2008 ; etheridge et al . , 2012 ) . some populations are also found in drainages to the white sea and in lakes of the upper volga drainage ( reshetnikov , 1980 ) .
, 2008 ) . within and at the fringes of its geographic range , it has also been translocated and introduced to many lakes and reservoirs where it was previously absent ( e . g .
the native vendace populations of the british isles are threatened ( etheridge et al . , 2012 ) .

vendace is a valuable species for freshwater fisheries and also marine fisheries in the bothnian bay ( northern part of the baltic sea ) and in the gulf of finland . vendace have been introduced into non - native lake systems in many countries ; in some of them changes within the colonizer population have been studied , and reduced food availability has been indicated . most introductions are related to deliberate stocking and / or aquaculture for the purpose of increasing the potential for freshwater fisheries . subsequent establishment and spread depends on the characteristics of the receiving ecosystem , and may be aided by the construction of reservoirs ( e . g . semenov , 2011 ) .
there are many accounts of introduction , mostly in europe within or at the fringes of the geographic range of native vendace . accounts also exist for more remote locations such as for maine , usa ( unsuccessful introduction ; fuller and nico , 2012 ) and for kazakhstan ( established ; mitrofanov and petr , 1999 ) . in norway , hatchery - produced vedace fry was deliberately introduced in a number of lakes between 1860 and 1900 . of the 16 documented cases , only one succeeded ( sandlund et al . , in press ( 2012 ) ) . although some of the introductions have been successful , probably most of them have failed .
