Answer: Silk is obtained from rearing of silkworms. Following the incubation period, larva hatches out of the egg known as caterpillar. Larva has a pair of salivary glands, termed as silk glands. Silk is secreted in the form of a liquid that hardens when exposed to air. A fully grown larva or caterpillar stops feeding and after that the cocoon is formed.

In fishing industries, exotic fishes such as common carp are also cultured. For the construction of a pond, land with clay soil is considered. Factors like temperature, light, oxygen, water flow and more of this pond are regulated to increase the production of fishes. Natural food given to fishes are microscopic aquatic plants and animals, while artificial food include husk of rice, bran of wheat, pieces of grain and more. All about Fish farming can be found here.
