    • Comparison of fishing efficiency between biodegradable PBSAT gillnets and conventional nylon (PA) gillnets 

      Grimaldo, Eduardo; Herrmann, Bent; Su, Biao; Føre, Heidi Moe; Vollstad, Jørgen; Olsen, Leonore; Larsen, Roger B.; Tatone, Ivan (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-19)
      Gillnets made of a new biodegradable resin (polybutylene succinate co-adipate-co-terephthalate (PBSAT) were tested under commercial fishing conditions to compare their fishing performance with that of conventional nylon (PA) nets. The relative catch efficiency between the two gillnet 15 types was evaluated over the entire winter fishing season for cod (<i>Gadus morhua</i>) in northern Norway. The ...

    • The effect of long-term use on the Catch efficiency of Biodegradable gillnets 

      Grimaldo, Eduardo; Herrmann, Bent; Jacques, Nadine; Kubowicz, Stephan; Cerbule, Kristine; Su, Biao; Larsen, Roger B.; Vollstad, Jørgen (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-05)
      The effect of long-term use on the catch efficiency of biodegradable gillnets was investigated during commercial fishing trials and in controlled lab aging tests. The relative catch efficiency between biodegradable and nylon gillnets was evaluated over three consecutive fishing seasons for Atlantic cod (Gadus morhua) in Norway. The biodegradable gillnets progressively lost catch efficiency over time, ...

    • Effect of mechanical properties of monofilament twines on the catch efficiency of biodegradable gillnets 

      Grimaldo, Eduardo; Herrmann, Bent; Jacques, Nadine; Su, Biao; Vollstad, Jørgen; Su, Biao (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-24)
      Gillnets made of the biodegradable resin polybutylene succinate co-adipate-co-terephthalate were tested under commercial fishing conditions to compare their fishing performance with that of conventional nylon polyamide (PA) gillnets. Both types of gillnets were made of 0.55 mm Ø monofilaments. However, since the biodegradable nets are weaker than nylon PA nets when using the same monofilament diameter, ...

    • 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 (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-20)
      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 succinate co-adipate-co-terephthalate (PBSAT) that are designed to degrade more readily in the envi- ronment. Gillnet filaments were incubated in microcosms of natural seawater ...

    • Fishing efficiency of biodegradable PBSAT gillnets and conventional nylon gillnets used in Norwegian cod (Gadus morhua) and saithe (Pollachius virens) fisheries 

      Grimaldo, Eduardo; Herrmann, Bent; Vollstad, Jørgen; Su, Biao; Føre, Heidi Moe; Larsen, Roger B.; Tatone, Ivan (Journal article; Tidsskriftartikkel; 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 trials covered two consecutive fishing seasons (2016 and 2017) for cod (<i>Gadus morhua</i>) and saithe (<i>Pollachius virens</i>) in northern Norway. Results generally showed ...
