Abstract
Godavari River at Nanded, Maharashtra, was selected as sampling site
for collection of the fish samples and obtained O. mossambicus fishes
are divided into three groups: a healthy control group, a group exposed to
aquatic insect toxins, and a group exposed to sub-lethal concentrations (1.25
ppm) of HgCl₂. The Folin-Lowry method is reliable to measure the amount of
protein hence it is used to measure the protein content in the gill, liver and
muscle tissues during a 15-day exposure period. The results revealed that, in
comparison to the control group, fish exposed to both biological and chemical
toxins had a much lower protein content. The toxins from gigantic water bugs,
or Belostomatidae, were the biological stresses that most severely
degraded proteins. Even at low concentrations, mercury chloride (HgCl₂) showed
notable toxicity on protein content of the fish tissues. Additionally, fish
exposed to chemical and biological toxins at the same time experienced
heightened effects, demonstrating a synergistic effect on tissue protein
degradation. This study emphasizes how critical it is to keep an eye out for
chemical pollutants and pathogenic insect infestations in aquatic environments
to protect fish health as well as biodiversity and its components. These
negative consequences might be lessened by putting tactics like habitat
management to control insect populations and tougher regulations for industries
to restrict mercury as well as heavy metal pollution into practice. The nutritional
value, assurance of no toxicity and ecological balance of Mozambique tilapia
(O. mossambicus) depend on such measures.
