RED BLOOD CELL MORPHOLOGY OF SOME FISH SPECIES IN HA TINH AND NHA TRANG, VIETNAMDo Huu Quyet, Hoang Thi Thuy Duong, Chernyavskikh S.D., Pham Huu Tinh, Tran Van Dat and Nguyen Tai TuAbstract The article presents the research results of red blood cell morphology of 6 fish species caught in the wild (Mugilidae sp., Decapterus sp., Epinephelus fuscoguttatus, Scatophagus argus, Aluterus monoceros, Pampus argenteus) and 2 cultured fish species (Sciaenops ocellatus, Lates calcarifer) in Ha Tinh and Nha Trang. The data obtained showed that the red blood cells of the wild and cultured fish groups both exhibited cytoplasm disorders but the degrees of manifestation were different, with the main abnormal forms being nucleus distribution and erythrocyte nucleus shape disorders, no disorder in the form of micronuclei in the cytoplasm were found. The group of fish caught from the natural environment and Lates calcarifer have a low rate of red blood cell morphological disorder, ranging from 0 to 2%, while for Sciaenops ocellatus, although the areas show different levels of disorders, all show serious morphological disorders, particularly it was up to 87% in some certain areasâwhich means that Sciaenops ocellatus is being negatively affected by external factors. Images and detailed analysis can be found in the article. |
