Abstract
Pangasius polyuranodon is present in the Pinang Luar lake. Residue of palm
plantation activities such as fertilizer, pesticide as well as soil particles may enter
the water and negatively affect the health of fish in general. A study aims to
understand the histological structure of the gill, kidney and liver of the fish has
been conducted in December-February 2021. Fish organs were histologically
processed and stained with HE. Abnormality and damage of the gill was noted
and categorized using Histological Alteration Index. Results shown that the types
of abnormality present were hyperplasia, hypertrophy and necrosis. In the gills of
2 fishes, there were Dactylogirus sp and Myxobolus sp parasites that may caused
the gill damage. The HAI value of the fish ranged from 1 to 102 (category I – III),
indicates that the gill of P. polyuranodon from the Pinang Luar lake is categorized
as normal to high damage. The histological structure of kidney and liver are
normal. In general, histological structure of the gill, kidney and liver of the fish
from the Pinang Luar lake are healthy.
