Myxobolus Bütschli 1882 is an important group of parasitic protozoa infecting a large number of freshwater fish species worldwide. The severity of Myxobolus infection leads to heavy loss in production of fishes. During the survey of the fish parasites, a new species of the genus Myxobolus have been isolated from the gills of a freshwater edible fish Cirrhinus mrigala Hamilton, 1822 from Canning, South 24 Parganas, West Bengal, India which has been described here.

Heavy metals in aquatic ecosystems accumulate in fish tissues, posing significant ecological and health hazards due to their toxic effects on both the environment and human consumers. The purpose of the study was to assess the potential hazards associated with consuming carnivorous, omnivorous, and herbivorous fish species from the Dhaleshwari River in Bangladesh. The study focused on the seasonal variation and accumulation pattern of toxic heavy metals in these fish species.

Understanding the mechanisms that promote coexistence between functionally analogous non-native and native species that share similar prey is important for predicting the ecological consequences of their competitive interactions. Theory predicts that species coexistence is facilitated by stabilizing mechanisms that enhance inter-specific trophic niche partitioning, and/ or the equalizing mechanisms that reduce differences in the average fitness. Inter-specific niche partitioning, influenced by the ecological opportunity in prey resources, also affects intra-specific niche partitioning and individual niche expansion.

is an important edible fish with a significant aquaculture contribution in Southeast Asian countries. The current study aims to enhance our understanding of the developmental biology of , which is crucial for implementing sustainable fish farming practices. To induce spermiation and ovulation in brooders, the synthetic hormone Ovaprim (GnRH + dopamine inhibitor) was administrated as a single injection dose of 0.

Fish egg quality is very crucial in aquaculture sector for production of healthy seed. Egg yolk is an energy reservoir for growth and development of embryo. This study evaluated the biochemical composition and quality of Cirrhinus mrigala eggs at three different hatchery sites of Pakistan, (Site 1= Fish Seed Hatchery, District Pakpattan; Site 2= Sidhuwan Hatchery, Head Balloki, District Kasur; Site 3= Chenab Fish Hatchery, Rangpur, District Muzaffargarh) during induced breeding.
