5. A trap net shall not be set in water more than 60 feet deep. A trap net
under this ruling is the same as that defined under regulation no. 4.
6. No more than two trap nets shall be placed in one string and *an open space free
from netting of not less than 50 feet shall be left between the nets.
7. In the event of a dispute between a trap-netter and a pound-netter concerning
the distance between nets, priority consideration shall be given the pound-netter if it is
established that he has fished for several years the grounds where his nets had been set.
Such consideration shall be given even though the trap-netter was the first to set his nets
on the. disputed grounds at the beginning of the season.
8. A trap net or a string of trap nets must be set approximately at a right angle to the
shore line or shoal or reef.
9. Regulations 2, 4, 5, 6, and 8 have been recommended for trap nets on the assumption
that they will be observed by pound-netters also. Enforcement is to be contingent
on the adherence of'pound-netters to these regulations.
APPENDIX D
THE WHITEFISH FISHERY OF LAKES HURON AND MICHIGAN, 1940-1942
Because of unavoidable delays in publication, statistics of the whitefish fishery have
become available for three additional years (1940, 1941, and 1942) since the preparation
of the main body of this paper and appendices A, B, and C. The data for these
years are presented in this appendix. Discussion is brief and is concerned chiefly with the
demonstration that the new information substantiates the conclusions drawn previously.
Emphasis is. placed on the detailed statistics for the State of Michigan waters although
production data are given for other areas.
