Acoustic ontogeny of a teleost

Abstract

The influence of growth on the intensity and variability of acoustic echoes from individuals and groups of a teleosts was quantified using Donaldson trout (rainbow-steelhead hybrid) Oncorhynchus mykiss. Fish growth was linear in total length (L T ) and quadratic in mass. Dorsal swimbladder area increased exponentially with L T . Allometric growth ratio (i.e. k) values of swimbladder length linearly increased with L T . Average swimbladder volumes occupied 3-6% of fish body volume and increased exponentially with L T . The aspect angle that resulted in the maximum average acoustic intensity from the group shifted from 80 to 86°through the experimental period. Mean echo intensities increased at both 38 and 120 kHz as mean L T increased. Predicted echo intensities at 38 kHz exceeded that at 120 kHz at L T <150 mm but were less than that predicted at 120 kHz at L T >280 mm. Generalized additive mixed models using L T , swimbladder angles and lateral elongation ratios of fish bodies were better predictors of echo intensities than L T alone.

Sound the alarm: A meta‐analysis on the effect of aquatic noise on fish behavior and physiology

“…As expected, negative biological noises were determined to have an adverse effect on fish behavior, whereas studies investigating positive biological noise all resulted in positive responses, but these responses failed to elicit a significant effect size. This is likely due to the low number of studies considered, as it has been suggested and well supported that species, especially those with anatomical modifications for sound projection or reception, can recognize and potentially evaluate sounds related to biological interactions (Fay and Popper ; Horne, ). The lack of research into this topic is understandable given the difficulty associated with replicating natural soundscapes under laboratory conditions; mostly due to issues surrounding the balance between sound pressure and particle velocity within a closed environment (Akamatsu, Okumura, Novarini, & Yan, ).…”

Common carp (Cyprinus carpio) response to two pieces of music (“Eine Kleine Nachtmusik” and “Romanza”) combined with light intensity, using recirculating water system

“…It is also well known that a number of fish species, using specifically modified anatomical structures, are able not only to produce but also to receive, to recognise, and to evaluate sounds, especially those related to their species-specific biological demands (Fay and Popper 2000;Frizsch 1999;Horne 2008;Popper and Schilt 2008;Popper et al 2003;Rollo and Higgs 2008).…”
