Analisis Fekunditas dan Diameter Telur Kerang Darah (Anadara antiquata) di Perairan Pulau Auki, Kepulauan Padaido, Biak, Papua
ABSTRACT: Analysis of
fecundity and egg diameter of cockles (Anadara antiquata) in Auki Island Water,
Padaido Islands, Biak, Papua. This research was carried out to analyzes
fecundity and egg diameter of cockles (A. antiquata) in sandy base and seagrass
bed in Auki island water, Padaido Islands, Biak, Papua This research was
conducted over 10 months (June 2009-March 2010).Samples were collected at
monthly intervals and were measured the shell length and body weight. The
colour of the gonad was used to determine the sex. Fecundity was calculated
usingthe volumetric method with Sedwigck Rafter counting cell (SRC cell). The
sex ratio was 1,00 : 1,92 for cockles in sandy base and 1,00:1,67 for cockles
in seagrass bed. Fecundity rangedbetween 100.068 - 4.288.312 for 51.70 to 70.80
mm in shell length for cockles in sandy base andranged between 134.025-3.127.500
for 41,20-66,80 mm in shell length for cockles in seagrass bed. Egg diameter
ranged between 20-64 μm for cockles in sandy base and ranged 10-64 μm forcockles
in seagrass bed.
