Anthropogenic boat noise reduces feeding success in winter flounder larvae (Pseudopleuronectes americanus)

Abstract

The aim of this study was to explore an emerging discipline addressing the impact of 20 anthropogenic noise on larval stages of marine organisms. We assessed the influence of 21 boat noise on the feeding behaviour of the pelagic larvae of winter flounder 22 (Pseudopleuronectes americanus, Walbaum 1792). The hypothesis was that boat noise 23 influences the feeding behaviour of P. americanus flounder larvae independently of prey 24 density. Aquaria containing P. americanus larvae were placed in water baths in which boat 25 aquaria with no sound 26 emissions. Larvae were filmed using cameras placed above the aquaria and their behaviour 27 was recorded. Larvae exposed to anthropogenic noise displayed significantly fewer 28 hunting events than controls, and their stomach volumes were significantly smaller. This 29 noise effect was the same at all prey densities used, suggesting that larval feeding behaviour 30 is negatively impaired by anthropogenic noise.

Annoying noise: effect of anthropogenic underwater sound on the movement and feeding performance in the red cherry shrimp,Neocaridina davidi

“…According to the results, in sound treatment significantly more individuals were distracted in feeding compared to the control treatment. Similar results have been reported in previous studies on another species of this order (Decapoda) and other species (Wale et al, 2013, Hastie et al, 2021, Gendron et al, 2020, Hughes et al, 2014, Voellmy et al, 2013). Wale et al, (2013) argued that, crabs Carcinus maenas , exposed to ship noise playback were more likely to suspend feeding than were those experiencing ambient-noise playback.…”

Gendron et al, (2020) found the presence of boat noise had a significant effect on the hunting behaviour of Pseudopleuronectes americanus larvae. Larvae exposed to boat noise spent less time hunting and had smaller stomach volumes compared to those with no sound treatment.…”

The Effects of Anthropogenic Sound and Artificial Light Exposure on Microbiomes: Ecological and Public Health Implications

“…For example, it is well-documented that anthropogenic sound exposure affects wildlife populations. Indeed, noise-induced reductions in foraging efficiency have been demonstrated in bats (Luo et al, 2015), owls (Mason et al, 2016), flounder larvae Pseudopleuronectes americanus (Gendron et al, 2020), and crabs (Wale et al, 2013). Chronic traffic noise can alter gene expression in bats, which associates with metabolic dysregulation and stress (Song et al, 2020).…”

Reduction of roadway noise in a coastal city underwater soundscape during COVID-19 confinement

“…Nevertheless, vessel noise contribution to the soundscape is less noticeable in the rms PSD because vessels were present less than 6% of a normal day and less than 1% for COVID-19 confinement. This result does not mean that vessel noise lacks the potential of affecting marine organisms as it has been shown in other studies, 28,29 but it may occur at specific moments or encounters rather than as a large contribution to the general underwater soundscape. Nonetheless, vessels are still detectable in the roughness of L01 in band 1–5 kHz [Fig.…”
