Losing the shellfish population can lead to significant changes in the ecosystem as well as negative economic effects, Gobler said. Shellfish will not be the only group affected. Gobler said that other fish species could be harmed by the increased acidification. "The early life stages of some fish are sensitive to acidification," Gobler said.Norovirus is a major cause of viral gastroenteritis, with shellfish consumption being identified as one potential norovirus entry point into the human population. Minimising shellnd an expression for the size of the population after tyears. Answer: As we saw in class, solutions of the logistic equation are of the form P(t) = P 0N (N P 0)e rt + P 0; where P 0 is the initial population and N is the carrying capacity. Hence, in this case P 0 = 400 and N= 10;000, so the sh population is given by P(t) = 400 10;000 (10;000 ...
