What do you mean by intensive and extensive fish farming?

What do you mean by intensive and extensive fish farming?

to fish farming conducted in medium- to large-sized ponds or water bodies; the fish production relies merely on the natural productivity of the water which is only slightly or moderately enhanced. Intensive fish farming, on the other hand, implies that the quantity of fish produced per unit of rearing area is great.

  • Tomato (hydroponics)

What is difference between extensive and intensive farming?

Intensive Farming is a farming method that uses higher inputs and advanced agricultural techniques to increase the overall yield. In contrast, Extensive Farming is one in which more and more land is brought under cultivation to increase the output produced.

Which conditions are controlled in intensive fish farming system?

Intensive Aquaculture Important environmental conditions is under control, measuring water temperature, dissolved oxygen, pH and salinity.

What are the benefits of intensive farming?


  • One of the fundamental advantages of intensive farming is that the farm yield is extremely high.
  • With the help of intensive farming, supervision of the land becomes easier.
  • The farm produce such as fruits and vegetables are less expensive when intensive farming techniques are employed.

What are the characteristics of extensive fish farming?

Extensive farming involves no feeding and no, or minimal, fertilization, semi-intensive some supplementary feeding and fertilization, and intensive steady supply of feed and fertilizers. The more intensive the production, the higher is the density of farm organisms in the farming medium.

How is fish farming practiced in the tropics?

As fish farming practices are very diverse, we have chosen to limit ourselves to small-scale freshwater fish farming in the tropics. And, as pond fish farming is the most common form of fish cultivation in these areas, the information provided focuses on pond construction and pond management.
