The production and farming of aquatic animals as fishes, prawns, shrimps, molluscs, lobsters etc. is called aquaculture.
We raise small nurseries where water is stored in small pits where we put fish seeds (fish eggs). From these fish eggs very small fish come out after hatching. Then these small fish are transferred to big ponds. These small nurseries where eggs hatch to give small fish are called hatcheries.
It deals with production and management of fishes. It is a scientific, systematic way of raising of fishes, their multiplication, their production and management. So it is used as food in a sensible way.

Long Answer Questions: Food Production ICSE Class-8th
Differentiate between an egger and a broiler.
Following are the differences between the egger and the broiler:
- Egg laying chickens are called eggers or egg layers.
- The chicks are given calcium (bones, seeds) and are reared to produce eggs.
- Eggers should give large number of eggs as white leghorns give many eggs. Rhode island red breeds like HH-260, IBL-80, B-77.
- Chickens which give us meat are called broilers.
- Those chicks are reared on a diet of fats so that they gain flesh on their body and these are used as broilers.
- Broilers should give flesh. Indigenous variety Aseel give high yield of meat and less number of eggs.

What are “milch animals”? Give three examples of exotic breeds of cow.
Milk-producing animals are known as “milch animals” e.g. cows, buffaloes, goats and camels. The milk from goats is nutritious and is sometimes preferred to cow milk. But the production of goat milk is much less than that of cows and buffaloes. Cow milk is quite nourishing and easy to digest, but as compared to buffaloes, cows produce less quantity of milk. Buffaloes are the major source of milk in our country.
Exotic (Foreign) breeds. For example. Jersey, Holstein- Friesian, and Brown Swiss.

Differentiate between food crops and cash crops and give two examples of each:
- These are crops which are grown for food such as cereals: wheat, rice, maize, pulses, oil seeds.
- These grow in the plains generally.
- These are annuals and complete their cycle in one season as in case of wheat, rice maize, gram, beans, peas.
- These are crops which are cultivated for commercial purposes such as tea, coffee, rubber, coconut, spices.
- These grow in the hilly areas on the slopes as water of rain should not stand in the roots as in case of tea.
- These plants are perennials. These plants live for more than two years. Tea, coffee require pruning before winter.
What are Kharif crops ? Give the name of the most important cereal plant of such crops. Briefly describe any three methods for cultivation of Kharif crops.
Kharif crops generally grow in rainy season. Rice is the most important cereal Kharif crop growing in India. It occupies the largest area in India. It needs rainfall from 150 to 200 cms. and requires flooded fields during its growth. and requires alluvial loamy soil.
