Biofouling in marine aquaculture: a review of recent research and developments
Bannister, Jana; Sievers, Michael; Bush, Flora; Bloecher, Nina (Journal article; Peer reviewed, 2019-07-24)Biofouling in marine aquaculture is one of the main barriers to efficient and sustainable production. Owing to the growth of aquaculture globally, it is pertinent to update previous reviews to inform management and guide ... -
Biofouling on salmon pen nets and cleaner fish shelters does not harbor planktonic stages of sea lice
Jevne, Lone Sunniva; Øvrelid, Margrete Slåtsve; Hagemann, Andreas; Bloecher, Nina; Steinhovden, Kristine; Båtnes, Anna Solvang; Olsen, Yngvar; Reitan, Kjell Inge (Journal article; Peer reviewed, 2020-09-01)The objective of the current study was to determine the extent to which planktonic sea lice (Lepeophtheirus salmonis Krøyer, 1838 and Caligus elongatus Nordmann, 1832) were present in the biofouling on open-sea net pens ... -
Effects of cnidarian biofouling on salmon gill health and development of amoebic gill disease
Bloecher, Nina; Powell, Mark; Hytterød, Sigurd; Gjessing, Mona Cecilie; Wiik-Nielsen, Jannicke; Mohammad, Saima; Hansen, Haakon; Floerl, Oliver; Gjevre, Anne Gerd (Journal article; Peer reviewed, 2018-07-06)This study examines the potential implications of biofouling management on the development of an infectious disease in Norwegian farmed salmon. The hydroid Ectopleura larynx frequently colonises cage nets at high densities ... -
Efficacy testing of novel antifouling coatings for pen nets in aquaculture: How good are alternatives to traditional copper coatings?
Bloecher, Nina; Floerl, Oliver (Journal article; Peer reviewed, 2020-03-30)Biofouling is a challenge in global sea-based salmon farming. Norway's salmon-growing industry relies primarily on copper-based antifouling coatings. However, copper is an increasingly recognised environmental hazard, and ... -
Efficacy testing of novel antifouling systems for marine sensors
Bloecher, Nina; Solvang, Torfinn; Floerl, Oliver (Peer reviewed; Journal article, 2021)Marine sensors are widely employed tools for remotely providing a representation of their environment. The primary factor limiting measurement accuracy and deployment longevity is biofouling. For prevention, copper is the ... -
Identification of spectral signature for in situ real-time monitoring of smoltification
Svendsen, Eirik; Volent, Zsolt; Schellewald, Christian; Tsarau, Andrei; Bjorgan, Asgeir; Venås, Birger; Bloecher, Nina; Bondø, Morten Steen; Føre, Martin; Jónsdóttir, Kristbjörg Edda; Stefansson, Sigurd Olav (Peer reviewed; Journal article, 2021)We describe the use of an optical hyperspectral sensing technique to identify the smoltification status of Atlantic salmon (Salmo salar) based on spectral signatures, thus potentially providing smolt producers with an ... -
Seatonomy applied in operational analysis of an autonomous net cleaning robot - NetClean 24/7 report for work package H1.1: Operational analysis and overall system design
Ohrem, Sveinung Johan; Kelasidi, Eleni; Bloecher, Nina (SINTEF rapport;2022:01107 A, Research report, 2022-09-23)This report presents an analysis of the autonomous cleaning operations handled in the NetClean 24/7 project. The analysis was conducted using the Autonomous Job Analysis (AJA) concept introduced in the Seatonomy method. ... -
Towards cost‐effective biofouling management in salmon aquaculture: a strategic outlook
Bloecher, Nina; Floerl, Oliver (Journal article; Peer reviewed, 2020-08-30)Biofouling is an ongoing challenge for marine salmon aquaculture, impacting farming operations, fish health and welfare. Current mitigation strategies employed in Norway and Scotland rely mainly on the use of antifouling ... -
Using acoustic telemetry to monitor the effects of crowding and delousing procedures on farmed Atlantic salmon (Salmo salar)
Føre, Martin; Svendsen, Eirik; Alfredsen, Jo Arve; Uglem, Ingebrigt; Bloecher, Nina; Sveier, Harald; Sunde, Leif Magne; Frank, Kevin (Journal article; Peer reviewed, 2018-10-01)The aim of this study was to demonstrate the feasibility of acoustic telemetry for monitoring fish during farm operations and gather knowledge about Atlantic salmon responses during crowding and delousing events in a ...
