I was hoping to get away without explaining, as it is complicated...essentially it is based on the assumptions that the data follows a normal (Gaussian) distribution, i.e. a bell curve, and there are an infinite number of possible fishing opportunities i.e. the population is infinite. Given that, there is a formula relating sample size, confidence interval (the amount of inaccuracy in your result, 1% in the example I gave) and confidence level (the probablility that your result is accurate to within the confidence interval, 95% in my example).

You can use a calculator to do the sum for you.
