Carry-Over Effects of Broodstock Conditioning on the Salinity Tolerance of Embryos of the New Zealand Geoduck (Panopea zelandica)

Figure 6

Abnormalities identified in D-veligers developed from embryos reared at 35 and 32 ppt salinity: (a) normally developing D-veliger for reference. Abnormalities included (b) (i, ii) indentation of the shell—exemplified in two individuals, (c) (i–iii) developmental issues around the shell margins—exemplified in three individuals, (d) (i, ii) concaving of the D-veliger shell hinge—exemplified in two individuals, (e) (i, ii) helical deformation of the shell—exemplified in two individuals, and (f) (i, ii) eversion of soft tissues—exemplified in two individuals. Black arrows indicate the locations of shell distortions.
