Question

Difference between intensive and extensive aquaculture

Answer 1

Answer:

Intensive Farming refers to an agricultural system, wherein there ishigh level use of labor and capital, in comparison to the land area. ExtensiveFarming is a farming technique, in which large farms are being cultivated, with relatively lower inputs, i.e. capital and labor.

Answer 2

Intensive Aquaculture.

• In intensive aquaculture, fish are raised in artificial tanks at extremely high densities. To regulate water quality, temperature, oxygen levels, stocking densities, and feed at the ideal level to promote growth, lower stress, control disease, and lower mortality, aquaculturalists must have a complete grasp of the targeted species.
• Despite being fully automated and self-sufficient, industrial aquaculture can have a negative effect on the environment.
• The inability to appropriately handle the nutrient-rich wastewater is the main issue brought on by extensive aquaculture.
• Organic and inorganic nutrients including phosphorus, ammonia, dissolved organic carbon, dissolved organic nitrogen, and dissolved organic phosphorus are abundant in effluent.

Extensive Aquaculture

• The alternative to intensive aquaculture is extensive aquaculture. In that less effort is put into fish rearing, extensive aquaculture is more fundamental than intensive aquaculture.
• The ocean, natural and artificial lakes, bays, rivers, and Fiords are all used extensively for aquaculture.
• These habitats have several mesh enclosures that keep fish captive and serve as harvesting trap nets. Fish are vulnerable to the elements, therefore choosing the right spot is crucial to ensuring the desired species grows quickly.
• The disadvantage of these facilities is that they rely on the nearby area's clean water in order to lower mortality and boost fish survival and growth rates.
