In this investigation, the effect of dietary administration of curcumin on the healing of skin wound in fish, Labeo rohita, has been reported. Fish were divided into three groups: control group (fish without skin wound), sham group (fish with skin wound without curcumin treatment) and curcumin‐treated group (fish with skin wound and subjected to dietary administration of 1% curcumin). Experiments were conducted for 30 days to assess the healing of skin wounds at different time intervals using scanning electron microscopy, histology, and mucopolysaccharide and enzyme histochemistry. In the curcumin‐treated group, healing of skin wounds was found to be enhanced than in the sham group as indicated by early restoration of morphology of the surface layer of epithelial cells; the density of the mucous goblet cells; the density of club cells in epidermal layer; and early granular tissue formation, collagen deposition and tissue remodelling in dermal layer. Furthermore, peroxidase and catalase enzyme activity showed increased endogenous defence system in the curcumin‐treated group compared with the sham group. It could be concluded that dietary administration of curcumin is beneficial in rapid healing of skin wounds in fish. Early healing of wounds could be considered to prevent the invasion of pathogens and to maintain the integrity of the surrounding tissue.
