Don Fishery Management Plan - RAFTS

3.1.4 Lamprey speciesThe adult sea lamprey Petromyzon marinus is occasionally noted in the lowest reaches ofthe Don, within 10km of the sea, possibly restricted from further movement upstream bythe remains of weirs in the river. Lampetra species recordings have been morewidespread but the species has only been positively noted as river lamprey (Lampetrafluviatilis) once in the late 1960s or early 1970s in the River Urie around Inverurie(DAFF record). In all other cases the species were either identified as brook lamprey(Lampetra planeri) or not identified beyond being Lampetra. Their presence, but nofurther information, has been recorded on the Fèith Bhàit at the head of the catchmentand many of the tributaries as far as the Elrick Burn (Shields, 1996). The NationalSurvey of Lampreys did not carry out any field work on the River Don and it was notedthat new and reliable information is required as the Don contains much suitable habitat(ERA, 2004).Figure 3.1.4 Distribution of Brook Lamprey4030BROOK LAMPREY /LAMPETRA sppDAFF data pre 2003Shields’ data 1996Don DSFB data 2000-2006Other data (see text)2010Includes material based on spatial digital data from the Centre for Ecology and Hydrology.
