Egypt would have lost its sharks

what the crew told us at the end of the cruise was that Yemeni fishermen took a year in prison and saw their boat destroyed following their arrest by the Egyptian army with their hugs full of shark fins.
we have this week and on two different boats seen no hammers no Longimanus very very little gray, only one or two foxes. The question is to check the info and when was the last time the usual fauna was observed.
