What is intensive method of fish culture?

What is intensive method of fish culture?

An intensive fish farming system is the well-managed form of fish farming, in which all attempts are made to achieve maximum production of fish from a minimum quantity of water. This system involves small ponds/tanks/raceways with very high stocking density (10-50 fish/m3 of water).

What are four basic types of intensive fish culture systems?

Types of aquaculture systems

• Water-based systems (cages and pens, inshore/offshore).
• Land-based systems (rainfed ponds, irrigated or flow-through systems, tanks and raceways).
• Recycling systems (high control enclosed systems, more open pond based recirculation).

What is extensive fish culture system?

Summary. Extensive aquaculture includes systems of culture and rearing in which human intervention is concentrated on reproduction of the stock in addition to capture. Compared to fishing, these systems make it possible to selectively increase the production of the species most in demand for man.

What are the types of fish culture?

(i) freshwater pond culture; (ii) rice-fish culture or integrated fish farming; (iii) brackishwater finfish culture; (iv) mariculture involving extensive culture and producing fish/shellfish (e.g., oysters, mussels, cockles) which are sold in rural and urban markets at relatively low prices.

What is the features of intensive aquaculture?

The more intensive the production, the higher is the density of farm organisms in the farming medium. In intensive farming systems, aimed at a high production, the density of farm organisms is often very high. Moreover, intensive systems are based on the cultivation of only one species (monoculture).

What is the difference between intensive and extensive on fish culture?

Intensive Farming refers to an agricultural system, wherein there is high level use of labor and capital, in comparison to the land area. Extensive Farming is a farming system, in which large farms are being cultivated, with moderately lower inputs, i.e. capital and labor. It is followed in densely populated region.

What is the difference between extensive and intensive aquaculture?

Extensive aquaculture is the other form of fish farming. Extensive aquaculture is more basic than intensive aquaculture in that less effort is put into the husbandry of the fish. Extensive aquaculture is done in the ocean, natural and man-made lakes, bays, rivers, and Fiords.

What do you mean by intensive and extensive fish 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.

What is semi-intensive fish farming?

For the purpose of the study, semi-intensive fish farming was defined as a fish farming practice where feeding is carried out at least two times per week and fertilizing once per week. Such a definition was chosen following consultation with aquaculture literature and technical experts familiar with the region.

What is intensive method?

Intensive method of agriculture aims to maximize use of per unit area of land. It might be both labour-intensive or capital-intensive. Due to high pressure of population, even the smallest part of the land is cultivated intensely.

What’s the difference between extensive and intensive?

Summary. An extensive property is a property that depends on the amount of matter in a sample. Mass and volume are examples of extensive properties. An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount.

Why fish culture is important?

Through aquaculture, our oceans, seas, and inland freshwaters hold huge potential to provide us with increased amounts of healthy and nutritious food. This is needed to feed an ever growing human population so aquaculture helps us with our ‘food security’.

What is intensive system?

Intensive farming is a technique used to yield high productivity by keeping large numbers of livestock indoors, it is an agricultural system that aims to get maximum yield from the available land. This farming technique is also applied in supplying livestock.

What is the difference between extensive and intensive fish culture?

What is semi intensive fish farming?

What is intensive cultivation?

Intensive cultivation implies constant raising of crops from the same plot of land. Thus, if more and more capital and labour are applied to the same plot of land, the system of cultivation is known as intensive.
