Aim: To assess the incidence and pathological effects during encysted progenetic Euclinostomum heterostomum metacercariae infestation in the freshwater fish spotted snakehead (Channa punctatus). Methodology: Samples of Channa punctatus were collected from Tilaiya Reservoir, Koderma, Jharkhand, India, during pre-monsoon, monsoon, and post-monsoon seasons. The encysted metacercariae trematodes were isolated from Channa punctatus. Characterization was performed based on the morphology and sequencing analysis of a partial 18S rRNA gene.

Abstract:
Channa punctatus, a species of freshwater fish, was subjected to an experiment to measure the effects of lead acetate on its morphology, respiratory rate, and operculum activity. The fish in the experiment were dosed with lead acetate, which might have entered their bodies through their gills, skin, or digestive systems. Lead acetate was shown to have accumulated on the gills, operculum, morphology, and respiratory rate of the cichlid fish Channa punctatus. Fishes are particularly vulnerable to the accumulation of heavy metals in fresh water since they are the top consumer in aquatic systems.

Increasing reports from emergency departments and law enforcement agencies detail acute cardiovascular and psychological effects from synthetic CB intoxication, such as JWH-018.
