Use the monthly capture-recapture data for eulachon fish below to estimate the population size using the Schnabel estimator. "mark" refers (10 points) The dataset includes the number of individuals caught each day (Catch), the number of those that are recaptures (Recaptures), and number of individuals newly marked (Newmarks). Hint: Does the Schnabel estimate use the NEW marked each day or some other metric? Make sure your results make sense given the data as a sanity check. As a reminder: n = sum(Mt*Ct) / sum(Rt) Where: n = an estimate of the true number (N) of individuals in the population at the time of initial marking. Mt = the number of individuals in the population that have been marked at the time the t sample was taken. Ct = the number of individuals captured at the sampling that occurred at time t. Rt = the number of recaptured, marked individuals taken at time t. eulachon <- data.frame(Month=1:5,Catch=c(29,34,28,20,25),Recaptures=c(0,14,10,8,9),Newmarks=c(29,20,18
