| Abstract |
Fish are cold-blooded vertebrates, whose body movements and balance are mainly using fins, breathing through gills, and living in an aquatic environment. Most vertebrates in the world are fish covering 48.1%, mammals (10.8%), reptiles (14.4%), amphibians (6.0%), and birds (20.7%). One of the fish consumed in North Sulawesi is scad mackerel locally called malalugis. This research focused on the meristic and morphometric characteristics of blue scad. The samples were caught in Makalehi waters and then landed in Manado Bay. Meristic observations (related to the number) included the number of spines and soft dorsal fin, pectoral fin, pelvic fin, anal fin (anal), and caudal fin. There were 9 spines on the first dorsal (D1), 2 spines and 30-37 soft rays on the second dorsal (D2), 3 spines and 24-31 soft rays on the anal fin (A), and 1,327 linea lateralis (LL). The morphometric observations cover total length, standard length, fork length, head length, tail stem length, eye width, body width, pectoral fin length, and anal fin length (anal). The total length ranged from 180 mm to 303 mm with a mean of 223 mm and a standard deviation of 25 mm. |
