Community Structure of Zooplankton in the waters of Kampung Ambong Likupang, North Minahasa
Abstract
Zooplankton has an important role as a linking chain between primary producers and biota at higher trophic levels. This organism is a component in the food chain that has a dual role as both the first consumer and the second consumer. They are intermediaries between plankton and nekton groups. This research was conducted at the field station of Fisheries and Marine Sciences Faculty of Sam Ratulangi University, which is located in Kampung Ambong, Likupang, North Minahasa Regency, to identify the species and to determine the structure of the Zooplankton community through: Density, Relative Density, Diversity (H ), Dominance (e ), and Uniformity (C). Based on the results of species identification, 20 species from 15 genera in 3 classes were obtained, namely Hexanauplia (13 genus 18 species), Crustacea (1 genus 1 species), and Malacostraca (1 genus 1 species). The results of the community structure analysis obtained moderate uniformity values at points 1, 2, and 3.The dominance index shows low values at all three points, where point 2 C = 0.17 and at points 1 and 3 C = 0.20 This means that there is no types of plankton that dominate the area. Temperature 28 ° C, Salinity 300/00, and pH = 7 indicate conditions that are still in a good range as a place to live and grow Zooplankton.
