High intensity, low frequency acoustic signals influence the spatial distribution and social interactions of European minnows (*Phoxinus phoxinus*). Anthropogenic noise may have direct fitness implications or wider impacts on fish population dynamics.
A combined approach meta-analysis was conducted to review the current state of knowledge on how anthropogenic noise affects fishes (vote counting: 114 studies); and to understand the broader scale ecological implications of differing impacts (anatomical, physiological, or behavioural) across developmental life-stages and aquatic environments (effect size calculation: 51 studies).
Relationships between mechanical response, and histopathological damage indices were investigated to gauge entire swimbladder response to infection. This study resolves previous incongruous findings when gauging swimbladder response to infection. We show that an increase in wall thickness raises the pressure require for organ rupture but decreases strength.
This paper is a write-up of a plenary talk at the 2019 “Effects of noise on aquatic life” conference (Den Haag, The Netherlands, July 7-12, 2019), the unusual topic having been suggested to the main author by the organizing committee for its ability to provide an unorthodox perspective. This is therefore not a review of two fields, but an exploration of whether a multidisciplinary perspective can bring benefits to either.
Relationships between mechanical response, and histopathological damage indices were investigated to gauge entire swimbladder response to infection. A mechanical-morphological trade-off reduces organ rupture, however, speculatively compromises efficiency of gas exchange.
In a controlled laboratory study, the response and tolerance of Eurasian minnow (*Phoxinus phoxinus*) shoals to tonal signals (150Hz of 1s pulse duration) differing only in temporal characteristics (“continuous,” “slow,” “intermediate,” or “fast” pulse repetition rate) were investigated.
A laboratory study investigated the group behavioral responses of common carp (*Cyrpinus carpio*) to tonal stimuli under the presence or absence of a background masking noise.
