Four strain~ of this fish were studied for phenotypic variation based on their meristic counts. Significant variation in counts of pelvic fin rays, anal fin rays, caudal fin rays and dorsal fill rays were observed among the strains. date: 2008 date_type: published publication: Malaysian Journal of Science volume: 27 number: 1 pagerange: 69-73 refereed: TRUE issn: 1394-3065 official_url: URL: http://www.ejum.fsktm.um.edu.my/ referencetext: Olivier K.
