The Brook Trout and Coaster information gathered here at Brook Trout Heaven, focus on Northwestern Ontario fly fishing and sport fishing in Lake Nipigon, Lake Superior and it's tributaries.
(all Brook Trout posted on this site were released)
The graph with the fish background is my represention of the blue MNR graphs at the bottom. It shows the percentage of the spawning population based on length of each fish measured.
This data was used to change the regulations to help protect the spawning population. Note the summary below the graph.
The "X" axis of the above graph is recorded in millimeters
Summary: The old 18" regulation protected 27% of the spawners at South Bay. Research indicates that the breeding population is around 200 to 300 fish. The RED bar graph data also represents that segment of the brook trout population that is now protected under the 22" regulations for the Nipigon system. This protects 87% of the population.
27% less than 18"(460)
13% larger than 22" (555)
60% between 18 to 22'
