Pooled samples and eDNA-based detection can facilitate the “clean trade” of aquatic animals
Individual-level sampling The probability of obtaining x infected individuals (D+) in a sample of size n taken without replacement from a population of size N, of which d are infected is described by a hypergeometric distribution81: $$P({D}^{+}=x)=frac{(begin{array}{c}d xend{array})(begin{array}{c}N-d n-xend{array})}{(begin{array}{c}N nend{array})}.$$ (1) However, diagnostic tests are rarely perfect. Infected individuals are correctly detected with probability Se […] More
