Abstract
This research was carried out from May to September 2013, located around Tallo River estuary, District of Tallo,
Municipality of Makassar, Indonesia. The aim of this research was to determine the contribution of environmental parameters on the
stability of ecological mollusks, using a quantitative method of sampling with a Principal Component Analysis Approach (PCA). The
results of this research are expected to provide an overview and information for further research and as consideration for stockholders
to ascertain the suitability of ecological habitats for the survival of molluscs.
The abundance and percentage of Molluscs were found in three classes
, i.e.,
285 ind/m
2
of Pelecypods or 61%, 95 ind/m
2
95 of
gastropods or 20%, 90 ind/m
2
of Bivalves or 19%. The contributions of environmental parameters as an identifier in management of
habitat of mollusc are that salinity is +0.1571 in the range of 20 to 31%. The contribution of the depth is 0.5284 with a value of 1-4
meters. A pH value is +0.5834 with a value of 7.7 to 8.2. Dissolved organic matter with a contribution is 0.0083 with a value of 21.98
to 52.74 ppm. Turbidity with a contribution is 0.1730 with a value of 2.8 to 7.25 NTU. The range is an optimal range for the growth
and survival of molluscs at the research location.

Introduction
Life of aquatic organisms is strongly influenced by
environmental conditions both organisms living in the
water column and on the bottom of water. The
organisms that live in the water column are called
pelagic organisms being able to move freely, while
organisms that live on the bottom of water are called
benthic organisms, where they are always associated
in the water either temporary or permanent. If
condition of water has optimal stability in supporting
the survival of the organisms, it is found the existence
of various types of organisms in the water that
reproduce perfectly and do every aspect of life such as
behavior, role of ecology, and pattern of distribution
will last well.
Benthic organisms are all kinds of the organisms
living and associated with sediments on the bottom of
waters, including basic plants (benthic plants) also
called as
fitobentos
and basic animals (benthic animals)
are called as
zoobentos
(Hutabarat and Evans, 1984).
One of the benthic animals is molluscs or soft animals
that generally have an outer frame or shell composed
of several classes. The large species are a part of the
marine , freshwater and terrestrial ecosystems. Some
of the organisms can be consumed by humans, which
are pests, or even very deadly poison predators.
According to Odum (1971), molluscs are benthic
organisms that holds a crucial role in the water
community, particularly in the processes of
mineralization and recycling of organic matter so that
they are key components of the food chain. This
relationship is based on the food chain of
detritus
commenced from dead organisms that are then untied
by microorganisms. These microorganismsconsumed
by detritivores. Moreover, the researcher further
asserts that macrozoobenthos has a vital role in
determining the secondary productivity that can render
the availability of food for other organisms and as an
indication of the potential suitability of the water
quality, especially as an indicator of the pollution.
