What are the importance advantages of aquaculture?

Aquaculture helps to reduce the reliance and impact on wild stock. The use of unsustainable fishing methods such as bottom trawlers is also reduced. Aquaculture systems often take advantage of harvested runoffs, storm water and surface water. This reduces the need to depend on other sources of water supply.

What is the importance of design of breeding Programmes in aquaculture species?

A selective breeding programme is designed to improve productivity over generations (a generation is the replacement of brood fish by their offspring). It is designed to increase growth rates and yields gradually over many years.

What is selective breeding in fish?

Solution: (b) Selective breeding is the process of crossing of two selected varieties having different traits to produce a hybrid having good traits of both, e.g., some breeds of sheep possess only soft under-hair.
