Biofouling monitoring for aquatic invasive species (AIS) in DFO Maritimes Region (Atlantic shore of Nova Scotia and southwest New Brunswick): Fs97-6/3158E-PDF

May–November, 2012–2015 /

"The establishment of four invasive tunicate species; Ciona intestinalis, Botryllus schlosseri, Botrylloides violaceus and Styela clava, has had detrimental impacts on the shellfish culture industry in Atlantic Canada, and there is a risk of introduction of additional tunicate species of concern. An annual surveillance and monitoring program for invasive tunicates, and other biofouling species, such as Caprella mutica and Membranipora membranacea, began in 2006 in DFO Maritimes Region. This report summarizes the results of annual monitoring in 2012 through 2015, conducted at geo-referenced coastal stations on the Atlantic shore of Nova Scotia (NS) and southwest New Brunswick (swNB). Thirty-two to 57 stations were monitored during three collector (monitoring plate) deployment periods: First (May – August), Second (August – October) and Full (May – October) in NS, while 14 to 18 stations were monitored in Second and Full deployment periods only in swNB. Water temperature, salinity and oxygen content were measured at each deployment and collection and hourly temperature data were collected during the Full deployment period at many sites in both regions. Four to 29 additional reports of tunicate presence or absence were received in NS during this study"--Abstract, p. v.
