Jenis Dan Kelimpahan Zooplankton Berdasarkan Kedalaman Yang Berbeda Di Perairan Kelurahan Teluk Makmur Kota Dumai
Teluk Makmur in Dumai City is a coastal area experiencing ecological pressure due to human activities, such as tourism and industry. Changes in water quality in this region may affect the structure of the zooplankton community, which plays a crucial role in the food chain. This study aims to determine the species and abundance of zooplankton based on different depths and stations. The research was conducted in November 2024 at Koneng Beach, Marina Beach, and Puak Beach. At each station, samples were collected at three depths (1, 3, and 5 m) using survey and purposive sampling techniques. Water quality parameters such as temperature, salinity, DO, pH, transparency, current, nitrate, and phosphate were also measured. Identification revealed zooplankton from the class Hexanauplia: Acartia sp., Calanus sp., Temora turbinata, Oithona sp., and Nauplius. The highest abundance was recorded at a depth of 5 m (41,542 ind/l), while the lowest abundance was found at depths of 1 and 3 m (0 ind/l). Based on stations, the highest abundance was observed at Station I (27,694.67 ind/l) and the lowest was at Station II (8,308.33 ind/l). One-way ANOVA test showed no significant difference in zooplankton abundance either between depths or between stations (p> 0.05).
