As fish grow in length, they increase in weight. The relationship between weight and

length is not linear. The relationship between length (L) and weight (W) is often modelled

by W = aLb

where W is the weight of a fish in kilograms, L is the length of a fish in

centimetre and a and b are constants. The constants a and b can be found for different

species of fish. The length measured is the fork length as shown in the diagram above.

You will be provided measurements for a small species of fish.

What would you expect a 65cm fish of this species to weight? Justify your answer.

You would need to tell us these values (a and b) in order for us to answer.
