Ocean acidification promotes otolith growth and calcite deposition in gilthead sea bream (Sparus aurata) larvae
Abstract The effects of ocean acidification on otolith crystallization and growth rates were investigated in gilthead sea bream (Sparus aurata) larvae. Larvae were exposed to three different pH levels: pH8.2, pH7.7 and pH7.3 for a period of 18 days post-fertilization. For the first time, we demonstr...
