On July 10, 2015 we deployed the remote set spat on shell treatments: 6 envelopes on racks, 6 envelopes on the ground and a comparable amount of shell directly on the substrate. Each envelope consisted of 2.5 Kg of spat on shell (Spissula primarily). Because of a shortage of remote spat on shell from the hatchery we had to half the amount of shell per treatment. Also the shell material differed from the non-remote set treatments (Spissula vs Crassostrea shells) so we will have to break the experiment into two independent studies. At right the experimental treatments, cultch in envelopes on ground, directly on the ground and envelopes on the racks.
