This screen gives details of the calculations performed to convert the length given in '*** Fish Size Quote ***' of the previous screen (Reference data detail) to a weight.

The weight of a fish at a given length may be estimated using one or more length-weight relationship formulae obtained from fishbase.org for that species. These are expressed for a specific length type (e.g. fork length, total length) and sometimes it is necessary to convert a fish length from one type to another in order to use them. The Overall result is the overall range of all values of Calculated weight lower and upper. Where separate length-weight calculations exist for both males and females, a mean is taken of the two.
