Abstract

The Identification System for Tanganyikan Cichlids (ISTC) is a computer system that identifies the species of Tanganyikan cichlids based on five meristic and three descriptive characters. An index Ii is proposed as the degree of proximity between an unidentified specimen and species i. For calculating this index, the system allows the use of the following: (i) the range data including the largest and smallest values of meristic characters; and (ii) the meristics, between which the correlations are unknown. Therefore, a large amount of data accumulated in literature can be used. This system is sufficiently practical, although the methods are simplified and mathematically coarse.
