Abstract

In repeated study of seed production of marble goby Oxyeleotris marmoratus under tank conditions at the Faculty of Fisheries and Marine Science Universiti Pertanian Malaysia serious morphological deformations of the seeds were observed in a batch with an extremely low survival rate. In this batch 47.3 of the seeds had deformations at the mouth operculum caudal peduncle pelvic fin and occipital region. Some fish lacked the complete operculum or pelvic fin. Poly-deformation was found to be 41.0 in the deformed fish. In fish with the caudal peduncle deformed the spine was twisted like an S. The deformed seeds were significantly smaller than normal seeds in total length and body weight p less than 0.05. The inability of the fragile larvae to consume enough live organisms in their early stages was attributed to their morphological deformations due to poor conditions of the brood fish or as a result of artificial spawning. These deformations were considered to be disadvantageous in feeding and eventually resulted in poor deformations might be attributed to malnutrition.
