It is utilized as an abrasive to assist in polishing ivory and wood as well as also to cover jewel boxes, books of fine quality and the handles of swords.

6. 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.

7. Isinglass

It is a gel-like substance that is derived from the air-bladders certain fish species like perches, carps, sturgeons as well as cat fishes, salmons cods, cods and others. The isinglass is a sparkling powder that is utilized for getting rid of beer, wine and other beverages, and also for making edible jelly for the making of adhesive materials.

The air-bladder is taken out of the fish, washed in cold water and then flattened beating it against the wood. The bladder is dried under the sunlight and exported to be used in the production of isinglass. The highest quality isinglass comes from Russia.

8. Medicines and Disease Control

Oils extracted in the refined form from the livers of sharks and cods are high in vitamin A as well as D. The pituitary glands produce essential extracts for medicine.

These fishes are propagated and widely distributed into tanks, ponds and lakes to kill mosquitoes that transmit malaria yellow fever and other horrible diseases that plague tropical regions.

Fishes such as dogfish (Scoliodori) Perch (Perca) as well as carp (Labeo) as well as others dissected to allow studying anatomical structures in zoological research labs. The research conducted in ichthyology is to benefit the fisheries as well as for the benefit of humanity.

One of the most extreme cases of particularization is the bony electric Eel (Electrophorus electricus) from the Amazon. It measures approximately 1.5 meters long, and the postero-ventral fourth fifth of its body covered by an electric organ. It is able to generate electricity of as high as 600 volts potential, with a maximum power output of 1000 Watts. Fish that eat carnivores consume the larvae of beneficial insects.
