Abstract

Currently, many people are interested in octopuses, from within the country to abroad. It is proven that if we look at the production value of octopus in 2010 - 2021, there is an increase every year. The octopus species that are exported are generally the Octopus cyanea type. The price of octopus on the export market ranges from USD 7-8 per kg. Octopus has quite high nutritional content and ranks third in the world of fisheries after fish and shrimp. This study aims to analyze the morphological and morphometric characters of octopuses (family: octopodidae) landed at Tanjung Menangis Beach, East Lombok Regency based on sex. This research was carried out from April to July 2023 by taking samples of octopus caught by fishermen at Tanjung Menangis Beach. Analysis of morphological and morphometric parameters was carried out at the Production and Reproduction Laboratory of the Aquaculture Study Program, University of Mataram. The morphological and morphometric parameters measured in male octopuses were 175 characters and 210 morphometric characters in female octopuses. Female octopuses have a relatively larger body size compared to male octopuses. The results of statistical tests using SPSS 23.0 showed that there were significantly different characters between male octopuses and female octopuses in the fishing area. Significant differences in characters include total length, dorsal mantle length, ventral mantle length, and dorsal mantle width
