Abstract: Mackerel scads (Decapterus spp) are important small pelagic fishes in Ambon Island waters and dominate the catch of purse seine in term of number and volume. One of the species of mackerel scads that can be found all year round in the area is Decapterus macarellus, however, there is no biological information about this species from Ambon Island waters. This research was conducted to study some biological aspects which consist of size distribution, growth pattern and condition factor of mackerel scad (D. macarellus) in Ambon Island waters. Samples of mackerel scad were collected weekly from purse seine fishers at Hitu village, Ambon Island, Maluku Province on February to March 2018. Totally, there were 279 of mackerel scad collected during the study with the total length ranging from 11.0 to 24.5 cm (mean 17.22±2.48cm) while the weight between 13 and 136g (mean 50.4±23.8g). Analysis of length-weight relationship showed that mackerel scad in the area have isometric and positive allometric growth pattern with condition factor close to unity.
