Ocean acidification promotes otolith growth and calcite deposition in gilthead sea bream ( Sparus aurata ) larvae
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 demonstrate that...
