Tuesday afternoon we saw dozens of blue claw crabs swimming on the surface. all were female and all had eggs .They weren't just swimming along, they had there back fins sticking up out of the water and splashing like mad .
The female crab has to have the right salinity and water temp. when she releases her eggs. If conditions aren't just right, they won't survive (eggs). My bet is that they are in a "panic" heading for better water. All the rain and flooding up river has to have changed conditions for them. They normaly head towards the mouth of the bay where the water is saltier and cooler.
We see them rather often while sharkin in the lower bay on the outgoing at night. This time of year they are particularly heavy along with all those damned jellyfish I always assumed it was an attempt to deliver thier eggs in the ocean or pretty close thereto. In the bay currents, up to a few knots , they must take one hell of a ride
