In three weeks' towing off Pictou, 319 first stage, 10 second, 2 third and 2 fourth stage lobster larvae were obtained. In the daytime at least, lobster larvae are largely concentrated at the surface and many thousands of crab larvae are captured with each lobster larva. Larvae are driven many kilometres offshore or onshore by the wind. First stage larvae were red in the daytime and blue at night in shallow water, and green in the daytime at the surface in deep water. All second, third and fourth stage larvae obtained were green.
