STRUKTUR UMUR GELOINA EROSA DI KAWASAN EKOSISTEM MANGROVE PESISIR BARAT KEBUPATEN ACEH BESAR
ABSTRACT: Mangrove cokles G. Erosa
lives in some of mangrove ecosystem (Estuaries), and one of mangrove ecosystem
area is in west Aceh Besar Regeny Coastal Area. G. Erosa has some generations
started from larva (juvenil), spat and adult age needs for further analysis.
The aim of this research is to make information about (1) measurement
dispersion group, and (2) structure of age the G. Erosa which live in the
mangrove ecosystem area in west Aceh Besar Regeny Coastal Area. The place of
this research is divided into three locations, and the obsevation was implemented
in June-August 2009. The total of plot sample in every four mounth and every
each plot is 10 m x 10 m in each inside there are 10 subplot 50 cm x 50 cm. All
subplots sampling arebroken by using scaped destructive metode sampling
quadrate, and to filt base water sedimen. The result showed that dispersion of
measure G. Erosa poin is around 1.05-8.55 mm to form 12 measure group,are is
dominated by juvenil. Structure of age is 3-6 kohort. Mangrove ecosystem area
in west Aceh Besar Regeny Coastal Area has 3-6 generation of G. Erosa.
