Report of the Danish Biological Station to the Ministry of Shipping and Fishing . hery has now almost entirely ceased there, it is saidfor want of Avhelks; nor do I know of other piaces in the country where themethod is still used. These whelk hivetraps are represented in fig. 7, one hangiugoutside the boat ready to be sunk down to the bottom. They are made of willowsand have a funnel-shaped opening et each end; one of the ends is loose, to betaken ofE when new bait has to be placed inside and the entrapped whelks takenout. The traps must have a weight to make them sink and lie steady, or thewhelks will not enter. They are furnished with a rope, which at the surface ofthe water ends at a wooden buoy, so that the traps can be found again. It wasat once found, that it was difficult in the Limfjord to buy bait for these fish, dried fish, salted fish were all too expensive. I then ordered second-class, but fresh, split cod through an Icelandic firm; it cost but some few øre perpound and turned out to be good. Tainted split cod, however, which I once got 12. in the Limfjord, was of no use;it smelt badly aod the Buccinumwould not touch it; Nassa how-ever en ter ed the traps butonly in small number.

To economize with thebait, the split cod, which isotherwise rapidly devoured bythe whelks so that the trapscatch 110 more, the pieces ofspht cod were euveloped in astrong steel wire through whichthe snouts of the whelks couldnot peuetrate. The bait couldthen last for some days in springand the trap continue to fish;as soon as the water gets warm,however, the bait must be chan-ged almost daily or it will the latter period thesteel wire was given up; but,to keep the bait from the whelksas long as possible, the piecesof split cod were hung by awire under the roof of the trap, thus away from the bottom. In this way wemanaged to keep the bait from bein
