Morphometric characteristics of fur Cockles (Anadara spp.) in Wonokromo and Juanda Estuary, Surabaya

Abstract

One of the invertebrate seawater animals that are considered to be a pollution existence parameter is fur cockles (Anadara spp). Further study is necessary to determine the environmental conditions that support the fur cockles' survival in the estuaries by observing the morphometric characteristics and analyzing the correlation factors between the fur cockle's growth and the environmental condition. This research was conducted in January and February 2017 in the river estuary area of Wonokromo and Juanda. Fur cockles (Anadara spp.) found in the estuarine area of Wonokromo and Juanda River were 18 - 57.59 mm in length with a rounded and thick shell. The shell color of the fur cockles in Wonokromo and Juanda are a blackish brown, while the flesh color in Wonokromo was observed to be darker than that in Juanda.
