Abstract
This study involves the use of the histology of the gills of a periwinkle species, Tympanotonus
fuscatus, as a biomarker tool, to investigate and evaluate the ecological pollution status of two
different water bodies, Bodo and Creek Road water-sides, in River State. The study involved the
sampling of ten (10) feral table sized fish from two stations along the creeks of the experimental
sites (Bodo and Creek Road water bodies), with similar specie, size and number from a reference
site (ARAC – African Aqua-culture Centre). The test fish gills were harvested from the fish caught
from both experimental sites for histological evaluation, while the control gills were harvested
from fish harvested from ARAC. The percentage prevalence of histological alterations showed that
fish from Bodo water-body had the worse outcome (25%), followed by Creek Road water-body
(21.7%) and ARAC having the best outcome (6.6%). Gills histology has proven to be an explorable
biomarker for evaluation of environmental status.
The use of fish Liver as a histological bioindicators is an important environmental biomonitoring
tool. Histological biomarkers were adopted to evaluate the health conditions of different
organisms and to indicate potential environmental hazards. Histotoxicology is applied as an
effective method to evaluate the influen...

Anthropogenic pollution is a major threat to coastal marine ecosystems. Due to their direct exposure to the surrounding water, fish gills are highly susceptible to contaminant-induced damage, making gill histopathology a valuable approach for evaluating the health status of fish populations in impacted environments. In...

This study assessed microplastic contaminations in African catfish (Clarias gariepinus) and
water samples from selected fish farms in Awka Metropolis, Anambra State, Nigeria. It also
examined the microplastic abundance, particle length, color, morphology, and polymer
composition in different fish tissues (gills, intest...

Batik wastewater is a significant environmental pollutant that may adversely affect aquatic ecosystems and human health. Its biological effects can be assessed using aquatic organisms as bioindicators. Suckermouth catfish and tilapia are fish species known for their adaptability to polluted environments; however, infor...

Anthropogenic activities from industrial, residential, and agricultural areas degrade river water quality through the release of organic pollutants and heavy metals. The Welang, Gembong, and Rejoso Rivers in Pasuruan Regency, East Java, Indonesia, are freshwater ecosystems exposed to these pollution sources. This study...

Coastal monitoring commonly relies on physicochemical measurements, which provide important information on seawater condition but may not fully reflect biological responses in resident organisms. This study established a species-specific histopathological framework for the rock oyster Saccostrea cucullata and evaluated...
