Arsenic speciation and arsenic feed-to-fish transfer in Atlantic salmon fed marine low trophic feeds based blue mussel and kelp
Silva, Marta Sofia; Tibon, Jojo; Sartipiyarahmadi, Sahar; Remø, Sofie C.; Sele, Veronika; Søfteland, Liv Ingeborg Rosvoll; Sveier, Harald; Wiech, Martin; Philip, Antony Jesu Prabhu; Berntssen, Marc HG (Journal article; Peer reviewed, 2023)Background: Aquaculture aims to reduce the environmental and climate footprints of feed production. Consequently, low trophic marine (LTM) resources such as blue mussels and kelp are potential candidates to be used as ... -
Cadmium in Brown Crab Cancer pagurus in Norwegian Waters
Wiech, Martin (Doctoral thesis, 2018-05-23)The Brown crab Cancer pagurus is appreciated as seafood and its fishery is of importance in several European countries. However, findings of high levels of cadmium have increased concern about food safety, and spatial ... -
Cadmium in brown crab Cancer pagurus. Effects of location, season, cooking and multiple physiological factors and consequences for food safety
Wiech, Martin; Frantzen, Sylvia; Duinker, Arne; Rasinger, Josef Daniel; Måge, Amund (Journal article; Peer reviewed, 2020)Brown crab Cancer pagurus is appreciated as seafood in several European countries. However, cadmium levels in crabs can be elevated and their consumption may pose a hazard for human health. To assess if cadmium poses a ... -
Cadmium in the shore crab Carcinus maenas along the Norwegian coast: geographical and seasonal variation and correlation to physiological parameters
Knutsen, Heidi; Wiech, Martin; Duinker, Arne; Måge, Amund (Peer reviewed; Journal article, 2018-04)Previously, high concentrations of cadmium have been found in the hepatopancreas of the edible or brown crab (Cancer pagurus) sampled from positions north of about 67° N, compared to regions further south along the Norwegian ... -
Differences in nutrient and undesirable substance concentrations in Maurolicus muelleri across the Bay of Biscay, Norwegian fjords, and the North Sea
Zhu, Yiou; Mahjour Azad, Atabak; Kjellevold, Marian; Bald, Carlos; Iñarra, Bruno; Alvarez, Paula; Boyra, Guillermo; Berntssen, Marc HG; Madsen, Lise; Wiech, Martin (Journal article; Peer reviewed, 2023)Introduction: We are having pressing issues of global food insecurity and malnutrition. Mesopelagic communities in the North Atlantic have been estimated to have high biomasses of organisms. Some of these low-trophic ... -
Effects of cooking and freezing practices on the distribution of cadmium in different tissues of the brown crab (Cancer pagurus)
Wiech, Martin; Vik, Eirin; Duinker, Arne; Frantzen, Sylvia; Bakke, Snorre; Måge, Amund (Peer reviewed; Journal article, 2017-05)Increased cadmium concentrations in claw meat were demonstrated after cooking and freezing practices of whole brown crabs. This was investigated in crabs from two different locations along the Norwegian coast, one with ... -
Growth Performance, Nutrient Digestibility, and Retention in Atlantic Salmon, Salmo salar L., Fed Diets with Fermented Sugar Kelp, Saccharina latissima
Sartipiyarahmadi, Sahar; Philip, Antony Jesu Prabhu; Sveier, Harald; Steinsund, Silje; Lock, Erik Jan Robert; Madaro, Angelico; Hansen, Tom Johnny; Wiech, Martin; Strand, Øivind; Jakobsen, Jan Vidar; Van Der Heide, Marleen E.; Nørgaard, Jan Værum; Remø, Sofie C. (Journal article; Peer reviewed, 2023)Using low trophic marine resources such as sugar kelp (Saccharina latissimi) is of great interest to increase the circular food production in the ocean. Sugar kelp does, however, contain high levels of carbohydrates and ... -
Opposite selection on behavioural types by active and passive fishing gears in a simulated guppy Poecilia reticulata fishery
Diaz Pauli, Beatriz; Wiech, Martin; Heino, Mikko Petteri; Utne-Palm, Anne Christine (Peer reviewed; Journal article, 2015-03)This study assessed whether fishing gear was selective on behavioural traits, such as boldness and activity, and how this was related with a productivity trait, growth. Female guppies Poecilia reticulata were screened for ... -
Targeted risk assessment of mercury exposure of recreational fishers: Are nephrops fishers in Norway at risk?
Wiech, Martin; Djønne, Christine; Kolding, Jeppe; Kjellevold, Marian; Ferter, Keno (Journal article; Peer reviewed, 2021)Recreational fishers often consume their catch, which may expose them to environmental contaminants. However, targeted risk assessment for exceeding the tolerable weekly intake (TWI) of a specific contaminant is often ... -
Tracing simultaneous cadmium accumulation from different uptake routes in brown crab Cancer pagurus by the use of stable isotopes
Wiech, Martin; Amlund, Heidi; Jensen, Karl Andreas; Aldenberg, Tom; Duinker, Arne; Måge, Amund (Peer reviewed; Journal article, 2018-05-24)High concentrations of cadmium in brown crab are an issue of food safety, and large variations between different areas have been found. To investigate the relative importance of dietary and aqueous uptake regarding the ...
