I put my hand in seven times and pulled up:
- Five very large (historic) green-lipped mussels, one had a top and bottom shell which I have not seen before but it broke
- Two scallop shells in ok condition, not particularly big, also saw a scallop on the surface
Straight away, lots of shell under the surface, very easy to find.
Massive school of blue mackerel or juvenile kahawai circled me as I ascended at 15m
