ABSTRACT 1 Since the last thorough review of the effects of anthropogenic noise on
cetaceans in 1995, a substantial number of research reports has been published and our …

As marine aquaculture expands around the world, there is increased concern for impacts to
protected species. Documented cases of marine mammal, sea turtle, seabird, and shark …

Acoustic deterrent devices (ADDs) to prevent pinniped predation on fish farms and fisheries
are widely used, but show highly varying success. Recently, ADDs have also been …

Fences can both enhance and detract from the conservation of wildlife, and many
detrimental impacts are associated with creating physical barriers. By contrast, virtual fences …

This report proposes and offers validation of a frequency weighted scale, the dBht (Species),
as a metric for the assessment of the behavioural and audiological effects on underwater …

In this review, we summarize and discuss the main interactions affecting salmon farming and
pinniped populations worldwide. Out of seven pinnipeds commonly engaged in these …

Acoustic harassment devices (AHDs) were deployed at salmon-trap nets in the Baltic Sea to
reduce gear and catch damage by grey seals (Halichoerus grypus). The AHDs emitted …

The marine aquaculture industry suffers losses due to pinniped attacks which damage net
enclosures and fish stocks. Acoustic harassment devices (AHDs) emit loud sounds which …

Seal scarers (or acoustic harassment devices, AHDs) are designed to deter seals from
fishing gear and aquaculture operations, as well as to prevent seals from entering rivers to …

The Baltic seal populations have been threatened by extinction due to a combination of
hunting and the effects of environmental pollution by organohalogens. By the 1970s, the …
