- How do you calculate N (population size)? Is the mark-recapture method a reliable way to estimate population size?Why is the minimum viable population size smaller for a geneticallydiverse population than for a less genetically diverse population?To measure the population of lake trout in a 250-hectare lake, 100 individuals were netted and marked with a fin clip, and then returned to the lake. The next week, the lake is netted again, and out of the 300 lake trout that are caught, 15 have fin clips. Using the capture-recapture estimate, the lake trout population size could be closest to? Also, what formula do I use to solve this problem? Thank You!
