• A global biogeographic classification of the mesopelagic zone (2017, background): “Gjøsaeter and Kawaguchi,1980 estimated their biomass at 1000 million tons, but acoustic surveys now suggest that mesopelagic fish biomass may be an order of magnitude higher (Kaartvedt et al., 2012).”
• Mesopelagic fish biomass in the southern California current ecosystem (2015, background): “However, more recent studies indicate that the biases due to avoidance and escapement from pelagic trawls may be even more severe, such that there may be an order of magnitude or more midwater fishes than previously recognized (Kaartvedt et al., 2012; Koslow et al., 1997; May and Blaber, 1989).”
• From siphonophores to deep scattering layers: uncertainty ranges for the estimation of global mesopelagic fish biomass (2019, background): “Although it is recognized that trawl avoidance by mesopelagic fish may lead to a large underestimation of their biomass by net sampling (Kaartvedt et al. , 2012), acoustic energy is not necessarily directly proportional to fish biomass and the acoustic energy is not only from fish and so the…”
• The future of food from the sea (2019, background): “although estimates are uncertain due to challenges associated with sampling and acoustic measurements (Kaartvedt et al. 2012; Irigoien et al. 2014; SAPEA 2017).”
• The biomass distribution on Earth (2018, background): “35 Nevertheless, previous estimates based on trawling are known to underestimate mesopelagic fish biomass due to escapes and avoidance of trawls (167).”
• Quantifying carbon fluxes from primary production to mesopelagic fish using a simple food web model (2019, background): “It may be, however, that this estimate is too low because mesopelagic fish can avoid pelagic trawls (Kaartvedt et al., 2012).”
• The trophodynamics of marine top predators: Current knowledge, recent advances and challenges (2015, background): “It is increasingly thought that the micronekton are undersampled by traditional net systems (by up to an order of magnitude; Kaartvedt et al. 2012).”
• Carbon export mediated by mesopelagic fishes in the northeast Pacific Ocean (2013, background): “Our capture efficiency estimates for mesopelagic fishes are consistent with published estimates for similar nets (Barkley, 1972; Baird et al., 1974; Kaartvedt et al., 2012), and the 2.1-fold difference in capture efficiency between the IKMT and MOHT is almost identical to the difference reported by…”
