Lacustrine, in open water. Spawns in January to February in shallow bays on stones and gravel. Feeds on crustaceans and insects (Ref. 59043).Status of threat: Threatened by degradation of water quality and introduction of Gymnocephalus cernua, which preys on egg and larvae. A second population is being established in Llyn Arenig (Ref. 59043).

Gwyniad ( Galce )

Rhywogaeth o bysgodyn dŵr croyw o deulu'r Salmonidae (neu'r eog) yw'r Gwyniad (Coregonus pennantii). Fe'i ceir yn Llyn Tegid yng Nghymru yn unig. Cred rhai fod y Gwyniad yn is-rywogaeth o Coregonus lavaretus a geir mewn rhai rhannau o Ewrop, yn enwedig Rwsia.

Treulia'r Gwyniad y rhan fwyaf o'i amser mewn dwfr dwfn, a dim ond pan maent yn dodwy eu wyau y maent yn dod i ddŵr bas yn agos i'r lan. Mynegwyd pryder am ddyfodol y rhywogaeth yn y blynyddoedd diwethaf, oherwydd diffyg ocsigen yn nyfroedd dyfnaf y llyn a ffactorau eraill. Yn 2003 dechreuwyd cynllun i ddal y pysgod pan font yn barod i ddodwy eu wyau a chymeryd yr wyau i safle arall, lle gobeithir sefydlu poblogaeth newydd.

Gwyniad ( İngilizce )

wikipedia EN tarafından sağlandı

The gwyniad (Coregonus pennantii) is a freshwater whitefish native to Bala Lake (Welsh: Llyn Tegid) in northern Wales.

The population is threatened by deteriorating water quality and by the ruffe, a fish introduced to the lake in the 1980s and now eating the eggs and fry of gwyniad. As a conservation measure, eggs of gwyniad were transferred to Llyn Arenig Fawr, a nearby reservoir, between 2003 and 2007.[2][1][3]

The taxonomy of the genus Coregonus is disputed;[4] some authorities assign the gwyniad to the common whitefish (Coregonus lavaretus),[2][5] and a morphological review in 2012 was unable to find any solid evidence for recognizing the gwyniad as a separate species.[6] FishBase and the IUCN list it as a distinct species, C. pennantii.[1][4]

Coregonus pennantii ( İtalyanca )

wikipedia IT tarafından sağlandı

Coregonus pennantii, conosciuto comunemente con il nome gallese gwyniad, è un pesce osseo d'acqua dolce appartenente alla famiglia Salmonidae.

Distribuzione e habitat

Si tratta di una specie endemica del lago di Bala nel Galles settentrionale. È una specie pelagica.

Biologia

Alimentazione

Si ciba di insetti e crostacei.

Riproduzione

Avviene in pieno inverno nelle baie con acqua bassa.

Conservazione

La popolazione di Gwyniad è minacciata dal peggioramento della qualità dell'acqua e dalle acerine, una specie aliena di pesci introdotti nel lago negli anni '80 che si nutre delle uova e degli avannotti del Gwyniad. Per questo, a scopo precauzionale, le uova di Gwyniad vengono trasferite al lago Llyn Arenig Fawr, vicino al lago di Bala[1][2].

Coregonus pennantii ( Felemenkçe; Flemish )

wikipedia NL tarafından sağlandı

Vissen

Coregonus pennantii is een straalvinnige vissensoort uit de familie van de zalmen (Salmonidae) en de onderfamilie van de houtingen. De wetenschappelijke naam van de soort is voor het eerst geldig gepubliceerd in 1848 door Achille Valenciennes. Het is een endemsische vissoort uit Wales die daar Gwyniad wordt genoemd.

Kenmerken

De vis kan maximaal 35 cm lang worden en heeft een aantal kenmerken die hem onderscheidt van andere soorten in hetzelfde meer. De vinstralen van de anaalvin zijn vertakt en 11 tot 13 in aantal. Er zijn 8 tot 10 schubben op een denkbeeldige lijn tussen de zijlijn en de borstvin en er zijn 36 tot 41 kieuwboogaanhangsels.[2][3]

Verspreiding en leefgebied

De soort komt alleen voor in Llyn Tegid, een meer met een oppervlakte van 4,84 km² in Wales. Zoals bijna alle soorten houtingen houdt de vis zich voornamelijk op in diep, open water. Zij paaien in januari en februari in de oeverzone boven stenige waterbodems met grind.[2]

Status

De soort wordt daar ernstig bedreigd door slechte waterkwaliteit en onnatuurlijke waterpeilfluctuaties. Bovendien is in de jaren 1980 de pos (Gymnocephalus cernuus) in het meer terecht gekomen. Deze baarsachtige vis predeert op het viskuit en vislarven van de zalmachtige vissoorten. Er zijn pogingen om Coregonus pennantii te introduceren in een kleiner meer in de buurt (Llyn Arenig) om zo de soort veilig te stellen. De soort staat als ernstig bedreigd (kritiek) op de Rode Lijst van de IUCN.[1]
