“…Thus, one could test the effects of temporal and/or spectral variations in the experimental noise, which can affect the possibilities of fish to adapt (Purser & Radford ; Neo et al . ; Nedelec et al . ; Shafiei Sabet, Neo & Slabbekoorn ).…”

“…In addition, the study of effects of noise on aquatic organisms has mainly been based on collecting correlative data (reviewed in Radford, Kerridge & Simpson ), although experimental studies are becoming more common (Bruintjes & Radford ; Holt & Johnston ; Neo et al . ; McLaughlin & Kunc ; Nedelec et al . ; Shafiei Sabet, Neo & Slabbekoorn ; Simpson, Purser & Radford ; Simpson et al .…”

Summary1. Studying the effect of anthropogenic noise on animal behaviour and physiology is a field of growing scientific and management interest. Anthropogenic noise is internationally seen as major environmental concern, but knowledge of the response of animals to noise and its ecological and evolutionary consequences is disparate. Even though fish and invertebrates form the majority of aquatic taxa, the effects of noise on these taxa are largely understudied. Especially the consequences of noise for short-range communication and behavioural interactions are yet unknown. While experimental studies on this subject are thus greatly needed, the expense of the equipment can be a main factor limiting data generation. Speakers that produce low-frequency sounds under water are currently either too large or too expensive to allow for sufficient replication in many research set-ups. 2. Here, we describe a device that can produce a low-frequency sound, which can be used as an experimental source of noise both in aquaria and in the field. The device is completely self-contained and costs around 10 euros per 'noise egg'. 3. The sound created consists of frequency bands (harmonics), which has the advantage that broadband and pulsed sounds, such as sounds produced by vocal fish, are easily detected in a spectrogram. Because the sound from the egg attenuates quickly, it can be used in aquaria and in the field to target certain study species or individuals without affecting a large part of the surrounding area. 4. We have developed the device to study the effects of noise on communication and behaviour in small aquatic animals; however, it could be used for other purposes, such as testing the propagation of certain frequencies in shallow-water habitats. 5. We hope the described method will facilitate the generation of experimental data on the effect of noise on behaviour and communication in aquatic animals in a wide variety of study systems and study areas.

“…For that reason, we cannot say if the effects of noise exposure would persist over a longer time period. Both zebrafish (Shafiei Sabet et al 2015) and European seabass Dicentrarchus labrax (Neo et al 2014) showed stronger negative effects when sound was emitted intermittently compared to continuously, in terms of activity, foraging performance, and behavioural recovery. Thus, both the duration and the temporal pattern of noise exposure may be important for longterm effects on fish behaviour and fitness.…”

“…In addition, noise can have behavioural effects on fish. Fish shoals have been shown to change their vertical movement and their shoaling structure in the presence of passing boats (Drastik & Kubecka 2005, Sarà et al 2007) and when exposed to artificial sound (Neo et al 2014(Neo et al , 2016. Also, increased swimming speed and change of habitat utilization have been found in connection with boating activities (Jacobsen et al 2014).…”

The negative impact of anthropogenic noise on marine animals is receiving increasing attention. In order to study the effect of motorboat noise on foraging behaviour in fish, we chose 2 species with different hearing abilities. The roach Rutilus rutilus has a better developed sense of hearing than the Eurasian perch Perca fluviatilis. The study took place in an inlet of the Bothnian Sea where boat traffic is almost absent. Groups of 6 fish were placed in field enclosures containing either one of the species or equal numbers of perch and roach. Half of each enclosure was covered with artificial vegetation. The fish were fed with pieces of saithe twice a day, both with and without the disturbance of an outboard motor. Sound pressure level and particle acceleration were measured for the motor, which was run at 2000 rpm. The trials were repeated for 5 d. Perch made fewer feeding attempts during noise exposure compared to controls in the singlespecies enclosures. As the experiment progressed, they gradually increased feeding and time spent in the open area, both with and without noise, indicating habituation. Habitat utilization was affected by the interaction of noise exposure and day. Roach responded to noise exposure with fewer feeding attempts, higher latency to enter the open area, and longer time spent in the vegetation compared to the controls without noise. Roach behaviour changed with time only when housed together with perch. This study, using authentic sound in a natural habitat, shows that noise exposure may affect the feeding behaviour of fish, that the response is species-specific, and that habituation and the presence of other species may modify the effects.

“…In the experimental studies on fish (Purser & Radford, 2011;Voellmy et al, 2014), it was assumed but not investigated that the effect of sound on foraging efficiency was caused by an impact on the predator and not on the prey and the relevance of temporal variation in sound characteristics (cf. Neo et al, 2015;Neo et al, 2014) remained unexplored.…”
