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.

Abstract:

Length-weight relationship (LWR) and condition factor (K) are fundamental tools to evaluate the growth of a fish population and the health of the aquatic habitat. The present study was undertaken to investigate the length-weight relationship and condition factor of three small indigenous fish species namely, Channa punctatus, Pethia ticto, and Trichogaster fasciata from the Turag River, Bangladesh. The fish samples were collected from three different sites (Aichi, Arichpur and Rajabari) during the month of December 2022 to February 2023. A total of 63 fish samples of different sizes were colle

To assess the proximate composition, five dried fish samples of Mystus vittatus, Channa punctatus, Chanda nama, Corica soborna and Trichuirus haumela were selected. The moisture content ranged from 14.06% to 24.58%, protein varied between 44.08% to 65.65% (moisture basis) and 53.45% to 76.39% (dry matter basis), lipid content of the selected dried fishes ranged from 1.91% to 17.76% (moisture basis) and 2.31% to 21.54% (dry matter basis). Ash content varied from 9.63% to 22.73% (moisture basis) and 11.21% to 28.15% (dry matter basis). The experiment was replicated three times and conducted from

Histopathology is an important diseases diagnostic tool. Penetration into the host is the first step for a microbial agent to mutiply and invade the vital organs of its host. Like all animals fishes suffers from environmental, stress, which is followed by pathogenic attacks and parasitic afflictions causing Epizootic Ulcerative syndrome (EUS). Histological investigations of tissues of EUS infected fish Channa punctatus showed an eroded epidermis, necrosis of skeletal muscles and intense granulomatous inflammation, infiltration of mixed inflammatory cells in muscular as well as submuscular laye

Abstract:

In Epizootic ulcerative syndrome (EUS) affected Channa punctatus and Clarias magur, the serum total proteins were decreased by 24.63% and 38.75% respectively along with A:G ratio. During immune response, the antibodies produced were found to be positively exponential with the amount of antigens (bacteria, fungus and viruses). The present changes may be because of the changing environmental conditions especially temperature fluctuations producing stress conditions in the fishes.
