Converting fish lengths to weights<br />
Converting fish lengths to weights<br />
Fish biologists have collected vast quantities<br />
of length and weight data from a variety of fish<br />
species. This has enabled length and weight<br />
relationships to be calculated for some fish<br />
species which can be used to estimate the<br />
weight of a fish by measuring its length.<br />
Please note that these figures are estimates<br />
only and individual fish weight may vary<br />
depending on age, sex, season and recent<br />
feeding activity.<br />
