Abstract

Mussel larvae of Mytilus galloprovincialis were grown in two pH treatments (pH 8.1 and 7.4). Larvae were collected for biological measurements of shell field development and calcification at 35 hours post-fertilization (hpf, trochophore stage). Calcein dye was added to the cultures prior to the start of calcification. Calcofluor is live dye and so was added to sampled larvae at 35 hpf for immediate imaging. Confocal microscopy was used for 3D imaging of larvae. Images were processed in ImageJ. S...

Mussel larvae of Mytilus galloprovincialis were grown in two pH treatments (pH 8.1 and 7.4). Larvae were collected for biological measurements of shell field development and calcification at 35 hours post-fertilization (hpf, trochophore stage). Calcein dye was added to the cultures prior to the start of calcification. Calcofluor is live dye and so was added to sampled larvae at 35 hpf for immediate imaging. Confocal microscopy was used for 3D imaging of larvae. Images were processed in ImageJ. Shell field area was determined as the area stained by calcofluor, on one valve. Calcification area was determined as the area stained by calcein, on one valve. See publication for details.
