Karyomorphological investigation of sand goby or marble sleeper (Oxyeleotris marmorata Blkr.) from CirataReservoir, 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).Â
