CHROMOSOMAL CHARACTERS OF THE INDONESIAN SAND GOBY, OXYELEOTRISMARMORATA BLKR. 1874 (ELEOTRIDAE)*)
AbstractKaryomorphological investigation of sand goby or marble sleeper (Oxyeleotris marmorata Blkr.) from Cirata
Reservoir, WestÂ Java,Â Indonesia wasÂ undertakenÂ toÂ determineÂ the modalÂ chromosomeÂ numberÂ andÂ fundamental
number, and to construct the karyotype from somatic metaphase cells of head kidney. A total of 30 fish samples
fromÂ CirataÂ ReservoirÂ wasÂ sacrificedÂ forÂ directÂ chromosomeÂ preparationÂ by
colchicine-citrate-aceto-methanol-Giemsa staining-air dryingÂ technique. Chromosome set analysis showedÂ thatÂ 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
