Normal distribution in fish populations

Marcus du Sautoy examines a sample of dover sole from a day's catch, and by measuring the weight of this small number of fish, explores how the bell-curve of the Normal Distribution allows us to predict what the largest fish in the population is likely to weigh, even without catching it. The calculations are not shown in full detail, but his prediction is backed up by a conversation with a fisherman.
