How do Spanner crabs respond to the net?
The study area has moderate bottom water currents, mean speed 9.6 cm s−1, and all spanner crabs arriving at the nets did so from down current of the nets. The rate at which spanner crabs responded to the bait rose to a peak between 12 and 21 min after the net was placed on the bottom and then declined.
How far can spanner crabs move?
From field data on current speed together with laboratory data on speed of movement of spanner crabs we estimated that in 30 min, crabs could be attracted from as far as 70 m from the bait. 80% of crabs that reached the net crossed on to it and 37% of these reached the bait.
What is an open end Spanner?
