Fish hearing sensitivity vaterite
WebMar 15, 2013 · Correspondingly, otolith crystallization – deposition of lower-density vaterite in place of high-density aragonite - has been associated with reduced auditory sensitivity (i.e., poorer hearing) in hatchery-reared chinook salmon . In the present study, fish from both Lake Quinault and Cook Creek hatcheries had high proportions of vaterite ... WebFish afflicted with this deformity can lose up to 50% of their hearing sensitivity right across their hearing range. More than a billion farmed salmon are harvested every year. To test if vaterite was a global phenomenon, we sampled salmon from the world’s major producers: Norway; Canada; Scotland; Chile; and Australia.

WebOtoliths are small bones near the brain of teleost fish that aid in hearing and balance. Otoliths are typically composed of a polymorph of calcium carbonate called aragonite; however, when stressed, fish may transition to producing a less dense polymorph called vaterite. Otoliths are typically used in studies of fish natal origin or migration patterns … WebJun 21, 2024 · Hearing, as defined by numerous investigators of vertebrate hearing, involves not only detection of a sound, but the ability to respond to the sound behaviourally. Thus, in order to understand what a fish (or any animal) hears, it is important to use behavioural methods that allow an animal to “tell the investigator” which sounds are ...
