Qualitative changes include the cessation of emperor fishing and the move to shark, ray and wrasse fishing, the cessation of shellfishing for limpets (Acmaeidae & Patellidae) and three bivalve taxa (
Cardiidae, Paphies striata and Soletellina tumens) and the uptake of Turbo into the diet.
Cladistic analyses based on morphological characters (Schneider, 1992, 1998) and phylogenetic relationships based on analysis of small subunit ribosomal RNA gene sequences (Maruyama et al., 1998) both indicate that the known bivalves with symbiotic dinoflagellates are closely related, all belonging to
Cardiidae. In addition, the available mol ecular genetic evidence (NcNally et al., 1994) reveals that the symbiotic algae associated with Corculum and Tridacna are also very closely related (LaJeunesse, 2000), but not identical.
