Abstract
Mangroves prove a habitat for Batillaria zonalis as nursery ground, feeding ground and reproductive ground. This research was conducted from September 2016 - August 2017 and to determine the spasial and temporal pattern with based on mangrove zone and environmental characteristics. The gastropods and environmental characteristics were analyzed using Principal Component Analysis (PCA). The results showed that significant changes in gastropod assemblages were primarily due to changes in the water quality and season. Correlation between gastropod and physico-chemical parameters in A. marina revealed significant relationship with gastropod B. zonalis distribution.
Highlights
Banggi coast is located on the North Coast of Banggi Coast in the North Coast of Java located in Rembang District, Central Java, Indonesia (6’30-7’06 S and 111’00 – 111’30 E)
Banggi Coast has a dominant mangrove The Banggi coast in Rembang, Central Java is fringed by various species of mangrove such as Rhizophora mucronata Lam., Rhizophora apiculata Blume, Rhizophora stylosa Griff., Avicennia marina (Forssk.) Vierh., and Sonneratia alba Sm (Ariyanto et al, 2018)
This research aims to determine spatial and temporal pattern of gastropods B. zonalis based on the environmental characteristics on A. marina zone in Banggi Coast, Rembang, Central Java, Indonesia
Summary
Banggi coast is located on the North Coast of Banggi Coast in the North Coast of Java located in Rembang District, Central Java, Indonesia (6’30-7’06 S and 111’00 – 111’30 E). The presence of antropogenic disorders, the development of aquaculture ponds and the expansion of settlements resulted in changes in the mangrove ecosystem These chages can alter the stability of mangrove structures, indivual pressures on distribution and organism abundance (Fondo and Martens, 1998; Beasly et al, 2005) and an important process in the food chain (Giesen et al, 2007). Based on this information, B. zonalis in shandy shore (Chan and Chan, 2005); feeding behavior (Kamimura and Tsuchiya, 2004); Diversity of Shell Colour (Miura et al, 2007) it is still minimal information about the distribution pattern of gastropod B. zonalis on the environmental characteristics. This research aims to determine spatial and temporal pattern of gastropods B. zonalis based on the environmental characteristics on A. marina zone in Banggi Coast, Rembang, Central Java, Indonesia
