River Annan DSFB Fisheries Management Plan 2009 – 2014Vendace Coregonus albulaVendace were once common in the lochs aroundLochmaben (Castle Loch and Mill Loch) but becameextinct some time in the late seventies through to thelate 80s due to eutrophication and the introductionsof coarse fish. They have since been successfully introduced to the catchment inLoch Skeen where a breeding population appears to have established itself. Thisis the only known breeding population in Scotland.Minnow Phoxinus phoxinusThe minnow is widespread throughout the riverand may have been introduced in the whole of theriver or it may be native. They have certainly beenintroduced into parts of the system (Loch Skeenfor example). The numbers tend to be higher in the lowland tributaries but theyare also found in upland environments where there are no obstructions (unlessmoved above those obstructions by man).Stone Loach Barbatulas barbatulusAs with the minnow, stone loach have been foundthroughout the river system, often in very highdensities in the lower and more enriched areas. Thedensities reduce in the upper parts of the river but they are still occasionallypresent. As with minnows they are not naturally found above obstructions butunlike minnows do not appear to have been introduced into any of these areas.Three-Spined Stickleback Gasterostreus aculeatusThese fish are found throughout the river system andalthough they are more common in the lowland areasthey are also present in most of the upland burns,albeit as infrequent samples in electrofishing surveys.Ten- Spined Stickleback Pungitius pungitiusAlthough these have never been found by the AnnanDSFB there are confirmed reports of their presence in thePow water from surveys carried out by other competentbodies (AERC). Whether the population still exists is not known.13
River Annan DSFB Fisheries Management Plan 2009 – 2014Sea Lamprey Petromyzon marinusSea lampreys are regularly seen spawning in highnumbers on the lower River Annan below Milnbie Caul.They have never been recorded above this barrier and itis assumed that this limits their presence in the river. Inthe Lamprey surveys carried out in 2002 and 2007 no sea lamprey ammocoeteswhere found. On the Kirtle and the Lochar where there are no barriers tomigration no sea lampreys have ever been recorded by the DSFBRiver Lamprey Lampetra fluviatilisIt is assumed that river lampreys cannot gain access to theRiver Annan for the same reasons that sea lampreysstruggle. On the Kirtle however there have been a couple ofrecorded adult lamprey sightings in the river upstream ofthe A75 and there is no reason why they could not migrate further upstream asthere are no further barriers.Brook Lamprey Lampetra planeriBrook lampreys are abundant throughout the whole of theRiver Annan catchment and all its tributaries wheresuitable habitat is available for the ammocoetes.Populations tend to be higher in the lowland parts of the river but occasionalsightings are confirmed in some of the upland areas.14
