“To harvest the marina shells, it requires the shell collector, to first study the tide level to find out what day of the month and the time of the day, that the tide level will be less than half a metre. Experienced collectors will be on the beach just before low tide, allowing time to set up as the tide runs out and gives a couple of hours to gather before the tides starts coming back into shore. The low tide needs to be during daylight hours as safety precaution. In a calendar year, the shell collectors may get two good tides for gathering. The shell collector tries to gather enough to last 12 months. They need about a sugar bowl full to freeze and mix with other shells to create her patterns for a number of pieces in a year. The regime allows time for the shells to continue to spawn. The full cycle from where the shells go out into 30 feet of water to breed drop the roe and come into shore and grown fully by end of April.
