Abstract
This study aims to analyze the diameter, size and growth type of sea urchins (Diadema setosum) on the islands of Kodingareng Lompo and Kodingareng Keke, Makassar City, South Sulawesi Province. This research was conducted for two months, from August to September 2022 on Kodingareng Lompo and Kodingareng Keke Islands, Makassar City, South Sulawesi Province. The number of sea urchins caught during the study was 1206 in August and 1066 in September. Sample analysis of sea urchins was carried out in situ on the island. Data analysis to determine the size distribution was carried out using a quantitative descriptive approach, including body diameter measurements. Based on the time of sampling in August, 12 classes were obtained with a mean size of 37.28 mm and a standard deviation of 14.34 mm with a total catch of 1206 individuals. In September, 11 classes were obtained with a mean size of 35.14 mm and a standard deviation of 13.62 mm with a total catch of 1066 individuals. The growth pattern of D.setosum sea urchins based on sampling time and station on Kodingareng Keke and Kodingareng Lompo Islands is negative allometric, namely the increase in shell diameter is faster than the increase in weight.
