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.
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 ... Webanistic understanding of how vaterite affects hearing. Lychakov and Rebane 17 developed a model for predicting the effect of otolith mass-asymmetry on fish hearing.
