Abstract

Karyomorphological investigation of sand goby or marble sleeper (Oxyeleotris marmorata Blkr.) from Cirata
Reservoir, West  Java,  Indonesia was  undertaken  to  determine  the modal  chromosome  number  and  fundamental
number, and to construct the karyotype from somatic metaphase cells of head kidney. A total of 30 fish samples
from  Cirata  Reservoir  was  sacrificed  for  direct  chromosome  preparation  by
colchicine-citrate-aceto-methanol-Giemsa staining-air drying  technique. Chromosome set analysis showed  that  the
modal chromosome number of the test fish is 2n = 46, confirming previous studies. Fundamental number is 50. Two
karyotypic formulas were found, i.e. 1) 2n = 46 (4SM + 42A); and 2) 2n = 46 (2M + 2SM + 42A).
