Abstract

The morphological characters are important information in the enrichment of scientific data of species in taxonomy knowledge and understanding the size variations associated with fishing activity aspect and its environment. The utilization of giant prawns in Kayan River produces many kinds of sizes and morphologic characters with have not been scientifically reported. The research aims to analyze the morphological characters and size composition of giant prawns (Macrobrachium spp.) in Kayan River, Bulungan Regency. The research was carried out from January to March 2023. Sampling was conducted 12 times with 30 individuals per sampling (a total of 360 individuals). Data collected include sex, chela pereiopods, color, abdomen, carapace, rostrum, uropods, walking legs, swimming legs, and genitals. The research results showed that the characteristics of shrimp patterns were bluish-green, brownish-green, yellowish-green, and white-green. Male and female prawns had similarities in the 5 greenish blue pole segments and brown claw tips a mud-like shape with a rough texture, and leg spines with 5 walking legs, and 5 swimming legs, but the difference between the claws and spines was that the male has bigger. The total length composition was formed into 9 classes with a size range of 8.4-26.2 cm, carapace length range of 2.9-9.9 cm, abdomen length of 5.4-14.5 cm, and weight composition of 5.0-245 g.
