Stergiou, K.I. Res. Actually, that’s not entirely true – nowadays, American trout anglers, who are some of the most radical conservationists in the angling world, have turned largely to length as a way of recording their catch-and-return successes.

However, published length-weight relationships are sometimes difficult to use, as they may be based on a length measurement type (e.g., fork length) different from one�s length measurements (expressed e.g., as total length). Baseline studies of biodiversity: the fish resources of western Indonesia. 1986. 1988. Handbook of freshwater fishery biology. Saila, S.B., C.W. Can. Hall. 23, 321 p. 1977. Res.

Standard weight in fish is the typical or expected weight at a given total length for a specific species of fish.
