Abstract

The abundance of phytoplankton and zooplankton have correlation with mangrove conditions in coastal area. The mangrove degradation give negative impact for abundance and diversity phytoplankton and zooplankton. The research aimed to analysis and construct prediction model of abundance and biodiversity of phytoplankton and zooplankton in mangrove ecosystem. The research used the transect method (to determine mangrove density), filtering method (to analyze abundance of phytoplankton and zoopankton) and statistical method (to develop estimation modeling of plankton abundance). The results showed that (1) the mangrove density between 250 trees/Ha - 1250 trees/Ha (2) the phytoplankton abundance were 10.675 Indv/L (in mangrove rarely) - 24.290 indv/ L (in mangrove high density), (3) the zooplankton abundance were 261 Indv/L (in mangrove rarely) - 2.204 indv/L (in mangrove high density) (4) The modelling analysis showed that (1) the phytoplankton abundance (y) = 0.0303 x2 - 22.059 x + 13004 and (2) the zooplankton abundance (y) = 0.0057x2 – 5.39 x + 1458.2, with x = mangrove densityKeywords: phytoplankton and zooplankton, mangrove density, abundance, estuary and lagoon

Highlights

Mangrove ecosystem is a specific community structure consists species composition, growth structure and productivity (Giesen et al 2006; Hilmi et al, 2015) and has important function as habitat of plankton and other organisms

The mangrove density in Meranti Island was dominated by Avicennia spp, Rhizophora spp, and Sonneratia spp (Table 3)

Summary

Introduction

Mangrove ecosystem is a specific community structure consists species composition, growth structure and productivity (Giesen et al 2006; Hilmi et al, 2015) and has important function as habitat of plankton and other organisms. The density and abundance of organisms can be used to analysis mangrove sustainability indicator (Ardli & Wolff, 2008; Badola & Hussain, 2005; Hilmi et al, 2017). Plankton consists of zooplankton and phytoplankton (Abdulwahab and Rabee 2015; Cairns and Pratt 1993; Effendi et al 2016; Honggang et al, 2012; Khalifa et al 2015; Li et al 2012; Mckinstry and Campbell 2017; Ormanczyk et al, 2017; Pratiwi et al 2016; Simanjuntak 2009). Zooplankton is unable to conduct photosynthesis due to lack of chlorophyll (Li et al, 2012; Masuda et al, 2017)
