For the shallow haul the net was lowered to 25 meters in most cases (but to 50 meters at Stations 7(B) and 9(C)) and hauled in at the rate of 5 meters every 5 minutes (5 meters every 2 minutes from 50-meter level), while the ship was steaming at 1% to 2 knots. For the deep haul, the net was lowered to the bottom at Stations 1-4, to about 275 meters at Stations 5-8, and to about 800 meters at Station 9, and then, while steaming, hauled up to 25 meters (or to 50 meters) at such a rate that - Carried out by Mr. Dean F.
