Environmental Description in the Design of Fish Farms at Exposed Locations
Kristiansen, David; Aksnes, Vegard Øgård; Su, Biao; Lader, Pål; Bjelland, Hans Vanhauwaert (ASME Proceedings | Ocean Space Utilization;OMAE2017-61531, Chapter, 2017-06-25)This paper addresses the description of exposure from waves and currents in coastal regions for design of marine fish farms. Representative descriptions of environmental conditions are important inputs to the design and ... -
The fate of conventional and potentially degradable gillnets in a seawater-sediment system
Brakstad, Odd Gunnar; Sørensen, Lisbet; Hakvåg, Sigrid; Føre, Heidi Moe; Su, Biao; Aas, Marianne; Ribicic, Deni; Grimaldo, Eduardo (Peer reviewed; Journal article, 2022)Abandoned gillnets in the marine environment represent a global environmental risk due to the ghost fishing caused by the nets. Degradation of conventional nylon gillnets was compared to that of nets made of poly- butylene ... -
Fishing efficiency of biodegradable PBSAT gillnets and conventional nylon gillnets used in Norwegian cod (Gadus morhua)and saithe (Pollachius virens)fishery.
Grimaldo, Eduardo; Herrmann, Bent; Vollstad, Jørgen; Su, Biao; Føre, Heidi Moe; Larsen, Roger B.; Tatone, Ivan (Journal article; Peer reviewed, 2018-09-10)Fishing trials were carried out to compare the relative fishing efficiency of gillnets made of a new biodegradable resin (polybutylene succinate co-adipate-co-terephthalate, PBSAT) with conventional (nylon) nets. The fishing ... -
An integrated approach for monitoring structural deformation of aquaculture net cages
Su, Biao; Kelasidi, Eleni; Frank, Kevin; Haugen, Joakim; Føre, Martin; Pedersen, Magnus Oshaug (Peer reviewed; Journal article, 2021)The majority of present marine finfish production is conducted in flexible net cages which can deform when they are subjected to water movements generated by currents. The ability to monitor net deformation is important ... -
Numerical and experimental study on the drainage and collapse of a floating flexible bag structure
Kristiansen, David; Su, Biao; Volent, Zsolt (Journal article; Peer reviewed, 2018-11)This paper addresses the possible drainage and collapse of closed flexible cages in sea-based fish farming. A closed flexible cage is a floating bag structure containing water that is enclosed from the ambient water. ... -
