Description: DFO Science monitors for AIS in the Gulf Region. The data collected from DFO’s biofouling monitoring program provides an overview of the distribution and abundance of Aquatic Invasive Species (AIS) in the Gulf Region. Native biofouling species are not included in this dataset. Included here is a dataset of detection and percent cover data of AIS. Biofouling monitoring is conducted using PVC collector plates that are deployed in the water column approximately 1 meter below the sea surface in the spring of each year. Biofouling organisms settle on these plates which are collected in the fall of the same year. Abundances of AIS are given as percent plate cover. All biofouling organisms settled on the underside of the PVC plates are noted and percent cover of each AIS is estimated.Botrylloides violaceus: Violet tunicateBotryllus schlosseri: Golden star tunicateCiona intestinalis: Vase tunicateStyela clava: Clubbed tunicateCaprella mutica*: Japanese skeleton shrimpMembranipora membranacea: Coffin box bryozoanCarcinus maenas*: European green crabCodium fragile*: Oyster thief alga*indicates species that are not included as percent cover as they are not accurately captured, but are included as detections.Les Sciences du MPO surveillent les EAE dans la région du Golfe. Les données recueillies dans le cadre du programme de surveillance de l'encrassement biologique du MPO donnent un aperçu de la répartition et de l'abondance des espèces aquatiques envahissantes (EAE) dans la région du Golfe. Les espèces de salissures biologiques indigènes ne sont pas incluses dans cet ensemble de données. Nous présentons ici un ensemble de données sur la détection et le pourcentage de couverture des EAE.La surveillance de l'encrassement biologique est effectuée à l'aide de plaques collectrices en PVC qui sont déployées dans la colonne d'eau à environ 1 mètre sous la surface de la mer au printemps de chaque année. Des organismes d'encrassement biologique se fixent sur ces plaques qui sont récupérées à l'automne de la même année. Les abondances d'EAE sont exprimées en pourcentage de couverture sur les plaques. Tous les organismes d’encrassement biologique installés sur la face inférieure des plaques de PVC sont notés et le pourcentage de recouvrement de chaque EAE sur les plaques est estimé.Botrylloides violaceus: Botrylloïde violetBotryllus schlosseri: Botrylle étoiléCiona intestinalis: Ascidie jauneStyela clava: Ascidie plisséeCaprella mutica*: Caprelle japonaiseMembranipora membranacea: MembraniporeCarcinus maenas*: Crabe vert européenCodium fragile*: Codium fragile*indique les espèces qui ne sont pas incluses dans les données de couverture en pourcentage car elles ne sont pas bien capturées par la méthode d'échantillonage, mais sont incluses dans les données de détection.
