| Abstract | Informative reviews on the environmental problems and pollutions in the estuarine are documented, and they found thataquatic organism has been radically affected. In this study, we thus assessed to establish baseline data on the liver histopathologycollected from ten estuarine fishes living in Pranburi River estuary (PRE), Thailand, during 2016-2017. The fishes were dividedinto two distinct groups, including pelagic fishes (Ambassis vachellii, Ambassis nalua, Auriglobus nefastus, Chelon subviridis,Eubleekeria splendens, Gerres filamentous, Lutjanus russellii, and Nuchequula gerreoides) and demersal fishes (Butis butis andUpeneus tragula). Livers of all fishes were morphologically observed and then processed by standard histological techniques.This study revealed that the hepatic vacuolar degeneration occurred in all fish species and indicative of hepatocellular lipidosis.However, we noted that this lesion exclusively occurred in demersal fishes. Some similar reports on the small sizes of themelanomagcrophage centers (MMCs) were mainly scattered in the liver tissue of demersal fishes. Interestingly, our study showedthat the blood congestion and proteinogenous plate in the central vein (30% prevalence in 2017) were first-detected in C.subviridis. All abnormalities seen in these liver samples indicated that all estuarine fishes, especially demersal fishes, mightassociate with the reduced functionality of liver as well as health status. Consequently, the environmental quality monitoring inPRE of Thailand should be additionally investigated in further studies. |
