Acoustic fishes encompass a diversity of different body plans, diel activity patterns, habitats and reproductive strategies.
Madsen concedes that the idea that seagrass provides acoustic refuge for fish makes sense.
Although not tagged with acoustic tags, these fish could have only come from one of the two FW release groups.
While the potential impacts of acoustic noise on fish hearing [7], [8], signal detection and communication [2] and stress responses [11], [12] have received a fair degree of attention, there is a general paucity of research examining how noise affects everyday behaviour of fish, and foraging in particular is largely unexplored in this context [2], [33].
"Abstract: To determine whether seismic exploration affected abundance or catch rates of cod (Gadus morhua) and haddock (Melanogrammus aeglefinus), acoustic mapping and fishing trials with trawls and longlines were conducted in the central Barents Sea 7 days before, 5 days during, and 5 days after seismic shooting with air guns.
However, stereo cameras can be viable tools for acoustic target verification of fish species and measurements of fish lengths, with the advantages of additional information on specific fish depth, tilt, and yaw.
When scientists slap an acoustic tag on a fish, they may be inadvertently helping seals find their next meal.
Notably, Dalhousie is the headquarters of the Ocean Tracking Network, a research effort using implanted acoustic transmitters to study fish migration patterns.
Because we had limited sample size for some species, an analysis of covariance (ANCOVA) was run to test whether acoustic variables related to fish size evolved in a similar way among five different groups.
