A net measuring 25 x 80 ft. was projected over waterfowl by using 3 small cannons. The propelling charge consisted of equal parts (by vol.) KClO3 and granulated white sugar. The cannons were fired electrically using No. 6 electric caps for primers. Total ground coverage by the projected net runs from 2800 to 3200 sq. ft., depending on weather conditions. Disturbance, as a result of using the trap on a refuge, was found to be slight. 2018 geese and 683 ducks were captured between the dates December 10, 1948 and December 31, 1949. Injuries resulting from the use of the trap were less than 1%. Estimated construction cost per trap $68. Since the trap may be used for both ducks and geese, it is cheaper than most enclosed-type traps for waterfowl. Cartridges cost 12[cent] each. The trap is easily camouflaged and completely portable. It may be used on land, at the edge of the water, or on ice. Smaller models can be made to be carried as a back-pack for use in remote areas. Minor limitations that have appeared are tangling of the captured birds in the net and damage to the net by rodents. Tangling was reduced by using six stake-down pins at the perimeter of the net to hold it flat and prevent the captured birds from balling up. An asphalt-base repellent reduced rodent damage. While used only on waterfowl to date, this trap should be effective for capturing upland gamebird species such as pheasants and wild turkeys. Plans and specifications for the construction of the cannon-projected net trap will be available for use by authorized persons, and may be obtained from the U. S.
