I obviously wouldn,t have the answer.
However, back in the Summer and Autumn, there were reports of lots and lots of "short" fish being returned, as many as 50+ a trip.
Those fish haven,t suddenly disappeared.
I don,t believe in Aliens, not even Georgia ones.
When the temperature drops, or there is a lot of freshwater in our estuarys, the fish find deep holes or channels and just sit there.
They don,t move, therefore they don,t spend energy, therefore they don,t need to eat.
When the water clears or warms, they feed like mad.
If there is loads of freshwater, they will move out into the sea, until they find a blend that suits them.
That means they could be in quite deep water.
But, once again, they don,t move, feed etc.
Could be a similar situation exists there.
