The Red-Claw crayfish, Cherax quadricarinatus is locally known as freshwater lobster
due to its lobster-like appearance and habitat. The aim of this study was to identified
the C. quadricarinatus for morphological and morphometrics characteristics study. A
total of 30 individuals has been analysing in the fisheries science laboratory of
Unversity Malaysia Terengganu for future analysis. Based on morphological examined,
the species can be distinguished from other crayfish by size, colour and the presence
of four distinct anterior ridges (carinae) of the carapace. For morphometrics
measurement, nine characters including weight has been chosen to be measured. The
One Way ANOVA, based on male and female of the species was calculated the
proportional ratio between the characters with total length. The carapace length,
abdominal width, chela width and chela length were significant meanwhile carapace
width, antennal length, abdominal length and telson length were not significant with
each other.
