Standard Length versus Total Length

摘要

In an effort to determine the length measurement most representative of the bulk of the fish, the standard length and the total length were each compared with the weight of the fish. This comparison was made for four species of game fish, yellow perch (Perca flavescens), wall-eyed pike (Stizostedion v. vitreum), rock bass (Ambloplites rupestris), and lake trout (Cristivomer n. namaycush). In each of the four species it was found that the weight could be estimated more accurately from the total length than from the standard length although with the wall-eyed pike the difference was inconsequential. Other advantages of the use of total length were outlined briefly.
