The present review article explains fish toxins from different species with their pharmaceutical and therapeutic uses. Fish stinging is a major problem in coastal areas as it exerts severe toxic effects mainly in fishermen, locals, and tourists. Fish toxins cause severe pain that radiates up in the limbs and regional lymphatics. These also impose venular stasis, hemorrhage and make changes in the arteriolar wall diameter. Fish toxins target ion-channels, ligand-gated channels and G-protein coupled receptors present in body cells and obstructs their physiological and metabolic functions. They affect molecules that participate in signaling pathways, and cause hemolytic, cardiovascular, and make obstruction in nerve function and smooth muscle contraction. For quick neutralization, fish venom-induced effects in victim’s toxin-specific antibodies are used. These quickly provide relief from pain, minimize the symptoms, and stop the immediate inflammatory reaction. Fish venom toxins are of wider biomedical applications and can be used for the preparation of immune diagnostics, bio-pesticides, anticancer agents, and analgesics by using its biological information.

Present review article explains the dietary and nutritional value of various fish derived natural food products. Dietary use of fish is a good source of important nutrients such as proteins, fats, vitamins and minerals.. Fish oil possesses polyunsaturated fatty acids (PUFAs) mainly  omega-3 fatty acids, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and eicosanoids. Fish consumption is world's prime source of high-quality protein; and about 14–16 percent of the animal protein consumed worldwide. This article also emphasizes therapeutic uses of fish oil in healing of wounds, hyperpigmentation, dermatitis, and in cardiovascular risks. Fish oil usage is good for skin-related diseases and for photoageing, cancer, dermatitis, wound healing, and melanogenesis. Fish oil polyunsaturated fatty acids (PUFAs) are highly beneficial in cardiovascular problems and dermatitis. These also affect neurotransmitter signaling and second messengers and shows antidepressant activity. In the present review various local, national, and international processed fish derived food currently available in the market fish dishes have been mentioned.
