Abstract

a large number of techniques, including a variety of indices, have been proposed and developed forassessment. Structural and functional variability have been summarized through both univariate andmultimetric indices as integrative indicators in environmental monitoring programs. In general, multimetricindices are considered to be sensitive, stable, and robust, thus offer a promising approach for ecologicalassessment. This study is aimed to assess the degree of sensitivity for several indices in terms of their abilityto determine environmental changes. Based on macrofaunal data, several univariate and multimetric indiceswere used to assess and compare the level of disturbance at fallowed farm and reference (control) sites. Thetwo multimetric indices, the AZTI’s Marine Biotic Indices (AMBI) and Ecological Quality Ratio (EQR), wereused as integrative indicators to assess the categorisation of each sampled site. The results showed that acombination of multimetric index and univariate indices provide a better assessment. The categoriesdetermined by multimetric indices seem to be in accordance with level of disturbance expressed by thetrophic analysis, multivariate and graphical analyses used in this study. The AMBI has the ability to detectlarge scale differences among sites. However, AMBI was unable to discriminate slight changes in themacrobenthic assemblages between sites, as have been exposed by EQR.

Abstract

Fish farming using floating cage has been conducted for a long time in Indonesia. Despite the benefits of aquaculture to meet the needs of the human protein, aquaculture has potential impact on the aquatic environment, especially due to the impact  of  organic  enrichment.  This  study aims  to  determine  the  relationship  of  water  physical-chemical  on  the abundance of mollusks as a biological agent to determine the level of environmental disturbance. This research was conducted in the waters of the Awerange Gulf, South Sulawesi. Mollusks samples were taken from two stations, namely the reference area and polyculture cage area with twice the sampling time and three   replicates. Abiotic and biotic relationships conducted using multivariate approach (Principal Component Analysis / PCA, BIO-ENV) using Eucladian Distance matrix. Based on the results, there were 15 species consisting of 14 families and 2 classes (gastropods and bivalves). Families were most prevalent in both sites was Turritellidae. In general, water quality in the Awerange Gulf is considered normal at both locations. Results of ordination using PCA on abiotic factors indicated that the stations between reference area and polyculture cage area are clustered, implying the difference of both sites. BIO-ENV analysis results indicates that the abiotic factors that most influence the distribution and abundance of molluscs in the Awerange Gulf were DO, Carbon and Nitrogen contain (r = 0.457; BIO-ENV). Keywords : Mollusk, Polyculture Cage, Awerange Gulf, Abiotic Component

Abstract

Phytoplankton are the dominant primary producers in aquatic ecosystems, Phytoplankton are sensitive  to   environment  as  changes.  Therefore,  the  phytoplankton  is  often  used  for bioindicators of water quality.  The purpose of this study was to obtain information on the abundance, diversity, evenness, and dominance of phytoplankton in Menjer Lake and examine the condition of the water quality and its effects on phytoplankton abundance. Research on the composition and abundance of phytoplankton in Menjer Lake was conducted in May 2015. Phytoplankton samples were taken using a plankton net size 25 µk and identification of phytoplankton using SRC and the microscope. The composition of phytoplankton in Menjer Lake consist of  40 species from six divisions in the following order: Bacillariophyte (17 species),  Chlorophyte  (15   species),   Cyanophyte  (3  species),  Chrysophyte  (1  species), Chryptophyte (1 species  ) and  Dinoflagellate  (3 species).  Phytoplankton abundance was highest at the net culture (11.884 ind/ l), then the abundance of phytoplankton low at the outlet station (8.476 ind/ l). The result of analysis on Phytoplankton diversity of stasions at Menjer lake the value 2,27-2,62 that means of high diversity. Uniformity index (e) at Menjer lake the value 0,84-0,92, that means the condition of phytoplankton community include into stable. Dominance index  (D) was highest at the outlet station phytoplankton species to dominate Aulacoseira granulata was indicated of its water is eutrophic. Keywords: Menjer Lake, bioindicators, phytoplankton
