Abstract

ABSTRACT            The Gastropod is macroorganism in the water. It is important for live organism in the water, it is as primary consumer. The research purpose to know the composition and structure of the Gastropod in the Kuantan river. The research was carried out in may of  2013 with a descriptive survey method in purposive random sampling with a set of field conditions based on station. This method is used because there are MCK, gold minning, rubber plantation. A total of  Gastropod species found are 14 species belong 9 genera, 4 families  and 1 ordo. Thiaridae  found as the families with the highest of species (7 species),  followed by Pleuroceridae (5 species), Pachychilidae and Cochlipidae  found 1 species. Melanoides anomala  found as dominant species (18,34%).  The highest of totally density showed in the station II (22,37 individu/m2) and the lowest density showed in the station III (16,00 individu/m2). Indeks diversity of  Gastropod in the Kuantan river turn 1,39-2,14, So the Kuantan river into medium pollution category. Physics and chemistry factor in the Kuantan river  suitable to life the Gastropod.

Abstract

ABSTRACT Muaro is one of the water bodies in which a variety of living organisms, the organism is clam shells Polymesoda bengalensis is known by the public as the seashell. The shells used by people around for a living because of the economic and nutritional value is very high. Current where abouts shellfish habitat Polymesoda bengalensis already disturbed. The most serious threat to the population is the result of harvesting clams and mussels taking excessive. Organisms that live in Muaro depending on substrate conditions and salinity, the salinity fluctuations depending on topography estuaries and tidal influence, the substrate  showed  differences  with  population densities. This factor  caused by  each type of  substrate occupied by Polymesoda bengalensis shells with different age groups. This study aimed to determine the distribution of oyster shell length and physical factors-water chemistry of mangrove clams Polymesoda bengalensis in Muaro Nipah Kecamatan Sutera Kabupaten Pesisir Selatan. The research was conducted in  January  2013  in  Muaro  Nipah  Kecamatan  Sutera  Kabupaten  Pesisir  Selatan.  Analyzes  were Polymesoda bengalensis conducted in the laboratory Animal Ecology Department of Biology, Faculty of Mathematics  and  Natural  Sciences,  Andalas  University  in  Padang,  this  determination  using  survey methods and sampling techniques using purposive systematic stratified random sampling in three locations determined by vegetation. Results of sample analysis shells Polymesoda bengalensis obtained size comparison long: thick : high = 2 : 1 : 2, there is a close relationship between the length and height with thick shells Polymesoda bengalensis. Biomass of meat is determined by the length, thickness and height shells. Length ranged shells 2.9–7 cm. Shell size distribution in strata I and III predominantly young individuals, in strata II adult individuals while on location I and III predominantly young individuals and locations II dominated by adult individuals.
