Question

Which of the following refers to seed in fisheries?
A. Fish
B. Eggs of fish
C. Feeders
D. Larva

Answer 1

Hint: Fishery is the entity which is engaged in the harvesting of the fish, and raising them through aquaculture. The seed in fisheries refers to the ‘“roe” of fishes.

Complete answer: The seed in fisheries refers to the eggs of the fish. These are fertilized cells which give birth to new young ones. A fish is edible and is included in people’s diet around the world, therefore, there is an increase in the demand of the fish. This demand of the fish has met stocking of the juvenile and rearing them into a suitable environment which ensures their growth and allows them to harvest more in a short period of time, which is known as the fish farming. The first step in fish farming is spawning, followed by the hatching of the eggs. The hatching stage where the eggs are hatched is a crucial stage as they encounter a large number of mortality. The good hatching rate will eventually result in the growth of the larvae. The baby fishes that are used as seeds in new ponds and fisheries are used in four stages; the hatchling stage, the spawn stage, the fry stage, and the fingerling also known as the juvenile stage.
Hence, the correct answer is option B.

Note: In the spawn stage, the mouth is formed and they are able to get the nutrition directly. In the fry stage, they are about two centimetres long and can eat zooplanktons present in the water, whereas fingerlings are about fifteen centimetres long and they are then transported to the ponds.
