Being wise after the event is not an option when mussels are about to spawn . In our case the decision was taken on 27-3-09not to harvest and as it turned out it was fortuitous, as mussel which had been collected on Saturday 28-3-09 for the Taste of the West show at West-point Exeter when cooked produced 20% meat content. If the decision had been to continue harvesting it would have needed 20% more mussels in a sack to achieve the correct weight.
Normally spawning would have occurred during the high tides when the larvae would have drifted further , but probably due to the sea temperatures being down for the time of year they had waited until the sea temperature was correct, which would appear to have been the weekend 27-28th March .
