Tripura is a north-eastern state of India with a total geographical area of 10,491 sq.km. Labeo bata, L. calbasu, L. gonius of the genus Labeo Cuvier and Cirrhinus reba of genus Cirrhinus Oken are the most popular and commercially important native minor carps of the state. During a detailed survey on the protozoan parasites of the minor carps of Tripura, two new species of myxozoan (Myxozoa: Bivalvulida) parasites Myxobolus tripurensis sp.n. and Myxobolus potularis sp.n. were encountered on the gill filaments of the host fishes. Distinctive characteristics of the plasmodia and the spores have been described.

The elemental composition of the fish otolith may represent a permanent record of the environmental condition the fish inhabited. Fish otolith grows incrementally from the core to a marginal region that acts as a repository of trace metal signatures. The present study explores the potential application of otolith microchemistry of the benthopelagic indigenous minor carp Bangana dero sampled from the Ropar wetland on River Sutlej, Punjab.

Tetrabromobisphenol A (TBBPA) is a widely used plastic additive with high bioaccumulation potential and toxicity on both humans and wildlife. Currently, research on its ecotoxicity and the underlying mechanism is limited. Using common carp (Cyprinus carpio), we evaluated the toxicity of TBBPA, especially focusing on its alteration of a key metabolism-related pathway aryl hydrocarbon receptor (AHR), using in vivo/vitro assays and in silico simulation.

An experiment was performed to investigate the potential of fructooligosaccharide (FOS) and Bacillus subtilis (BS) (alone or as synbiotics) in promoting growth and immunity against infections in Labeo fimbriatus fingerlings. Six iso-nitrogenous and iso-lipidic diets containing combinations of two levels of FOS (0% and 0.

In this study, we established a murine cell line that expresses ginbuna crucian carp (ginbuna) CD4-2 and used it to develop an anti-CD4-2 monoclonal antibody (mAb). An established mAb, named D5, showed good reactivities to BALB/c 3T3 cells expressing CD4-2 and a lymphocyte population in the ginbuna leukocytes. Gene expression analysis showed that D5 cells express CD4-2 and TCRβ genes but not CD4-1 and IgM genes, meanwhile May Grunwald-Giemsa staining of sorted D5 cells had the typical morphology of lymphocytes.

Gut microbiota and their metabolites are increasingly recognized for their crucial role in regulating the health and growth of the host. The mechanism by which the gut microbiome affects the growth rate of fish (Cyprinus carpio) in the rice-fish coculture system, however, remains unclear. In this study, the gut contents of the fast-growing and slow-growing (FG and SG) carp were collected from the rice-fish coculture system for both the fish gut microbiome and metabolome analyses.
