Question

Differentiate between Culture fishery and Capture fishery.

Answer 1

Hint: Fishery refers to the practice of collecting fishes for economical purposes such as food, for scientific purposes, for by products such as oil, glue etc. Culture fishery and Capture fishery involves creating and capturing fishes respectively.

Complete answer:

Capture fishery	Culture fishery
Capture fishery involves catching fish directly from water bodies i.e. lakes, sea, ponds, etc.	Culture fishery involves growing, rearing, and then capturing of fishes from fish tanks.
The capture is done from natural water bodies such as oceans, rivers, lakes, and ponds.	The culture of fishes is done in restricted self-made water bodies.
This method involves the natural development of fishes i.e. No need for taking care of fish.	Individuals handling the body must take care of the growing fishes to achieve maximum yield.
Any fish whether matured or immature get trapped while capturing.	Only matured fishes are captured.
It is a random process of capturing fish.	It is a defined method since only fishes needed are grown.
In simple terms, this method involves collecting.	This method involves rearing.
Fish yield decreases gradually due to random capture.	Fish yield can be increased as per the need by selective breeding.

Note:
- In capture fishing; overfishing, pollution, and other environmental factors affect the fish yield.
- Culture fishery is the preferred method.
- Nowadays, culture fishery is also called aquaculture due to the rearing of a variety of aquatic animals other than fishes such as prawns, crabs, etc.
