Abstract

Octopus is a commodity that has important economic value and high export value. Gugop Distric is one of the producers of octopus in the form of fresh products and processed products developed by Kube Mangat. It is said that the octopus species in Indonesia are dominated by Octopus cyanea, but there is no scientific certainty for the type of octopus in this Gugop village. This study aimed to identify morphometric analysis is for octopus. This research conducted in May-July 2022. Information on octopus resources in Aceh is still limited. Information about octopus biology needs to be known as basic information in octopus resource management. A total of 35 octopus samples were obtained, there are 5 key characteristics in Octopus cyanea including ocellus, bluish-white spots, brown markings all over the body, diamond-shaped papillae on the neck and head. The presence of false eye spots indicating that this species is Octopus cyanea. The size trend based on the total length of the octopus showed 6 classes with the highest total in the 68-72 cm category, namely 9 individuals.
