The importance of fishes can be discussed under the following headings.
1. Food value
Fish serves as an important food for human. Edible tissues of fish are appreciably greater than that in chicken, pig and sheep/goat.
2.Medicinal value
Fish is low in fat, high in protein and an excellent source of Omega-3 fatty acids. Regular consumption of fish can reduce the risk of various diseases and disorders. Some research findings indicate the following:
Asthma: Children who eat fish are less likely to develop asthma.
Cancer: The Omega-3 fatty acids in fish reduce the risk of many types of cancers by 30 to 50 percent, especially of the oral cavity, oesophagus, colon, breast, ovary and prostate.
Cardiovascular disease: Eating fish every week reduces the risk of heart disease and stroke by reducing blood clots and inflammation, improving blood vessel elasticity, lowering blood pressure, lowering blood fats and boosting good cholesterol.
Dementia: Elderly people who eat fish or seafood at least once a week may have a lower risk of developing dementia, including Alzheimer’s disease.
Depression: People who regularly eat fish have a lower incidence of depression. Depression is linked to low levels of Omega-3 fatty acids in the brain.
Diabetes: Fish may help people with diabetes to manage their blood sugar levels.
Prematurity: Eating fish during pregnancy may help reduce the risk of delivering a premature baby.
Further, it is observed that different fishes are used as Ayurvedic medicines which help in treatment of duodenal ulcers, skin disease, night blindness, weakness, loss of appetite, cough and cold, bronchitis, asthma, tuberculosis, etc.
3. Decorative value
Many species of colored fish are kept in aquarium, ocenarium, ponds and lakes for decoration or ornamentation.
4. Fish Skin and Leather:
The skin of several fishes like the sharks and rays are used for making polishing and smoothing material. Shark skin leather is of some commercial importance in the manufacture of many useful articles such as shoes and hand bags, etc. In Japan, lantern are prepared from the skin of puffer fishes (e.g., Tetrodon). Some tribal people used skins of puffer and porcupine fishes {e.g., Diodon) for war helmets.
Crude skins of sharks and rays are used by carpenters and metal workers. Shark skin tanned with placoid scales on it is called shagreen. It has been used as an abrasive for polishing wood and ivory and also for covering jewel boxes, fine books and sword handles.
5. Fish Glue:
Liquid glues are prepared from skin, head and other trimmings of certain fishes. This glue has an adhesiveness of great power for paper, wood, leather and glass.
6. Fish Fin:
The fins of sharks are exported to China where they are used for preparing soup.
7. Fancy Articles:
Scales of garpike (Lepidosteus) are used for jewelry and novelties. From scales of some fish is secured a pigment whose water suspension is known as pearl essence. It is used in the manufacture of artificial pearl in Europe, especially in France.
8. Industries:
As the fish forms a rich source of food, millions of people are engaged in fishing industry and depends on fisheries for their livelihood in various ways. Besides those who directly catch the fish for marketing, there are equally large number of people engaged in subsidiary industries like refrigeration, preservation, canning, and in the manufacture of fish products and by-products.
9. Scientific Study:
Fishes have considerable use as experimental animals, especially in the fields of Genetics, Embryology, Animal Behaviour and Pharmacology. Certain fishes such as Latimeria and dipnoans have anatomical features of great zoological interest. Fishes like dogfish (Scoliodori), perch (Perca) and carp (Labeo), etc., are dissected for anatomical study in zoological laboratories. Researches in ichthyology are conducted for the benefit of fisheries and mankind.
