What are advantages and disadvantages of composite fish culture?

What are advantages and disadvantages of composite fish culture?

1) Various species of fishes are cultured altogether. 2) Ensures complete utilization of food in pond. 3) Increase in fish yield.

What are advantages of composite fish culture?

An advantage of composite fish culture is that it increases the yield of fish. In a composite fish culture, five or six different species are grown together in a single fish pond. Fishes with different food habitats are chosen so that they do not compete for food among themselves.

What is the major problem in composite fish farming How is this problem overcome?

Even if fish seed is collected from the wild, it can be mixed with that of other species as well. So a major problem in fish farming is the lack of availability of good quality seed. To overcome this problem, now some ways have been worked out to breed these fish in ponds using hormonal stimulation.

What are advantages of fish culture?

1. Fish provides high quality animal protein for human consumption. 2. A farmer can often integrate fish farming into the existing farm to create additional income and improve its water management.

What is harmful for fish culture?

Explanation: weeds are very harmful becuase it releases some harmful chemicals into the water and it does not disolve oxygen and causes death of the fishes.

What are the risks disadvantages of the use of aquaculture?

Fish farms can impact wild fish populations by transferring disease and parasites to migrating fish. Aquaculture can also pollute water systems with excess nutrients and fecal matter due to the large numbers and concentrations of farmed fish. Sometimes equipment used in aquaculture can be problematic.

What are some advantages and disadvantages of fish farming?

Fish Farming Pros & Cons

• Pro: Replenishment. Fish farming allows us to replenish the food fish supply at a faster rate than the oceans can produce it, allowing suppliers to keep up with demand.
• Pro: Employment.
• Pro: Nutritional Provisions.
• Con: Environmental Damage.
• Con: Feeding.
• Con: Lice and Bacteria.

Why is composite fish culture better than monoculture or single fish culture explain?

Composite fish culture is undoubtedly more superior over monoculture. Fast growing, non-predatory, non-competable species of food fishes are cultured together with complementary feeding habits and capable of utilizing both the natural and supplementary fish food. At the same time one fish is useful to the other.

What are the problem of composite culture?

– One problem with such composite fish cultivation is that many of these fish only breed during monsoon. While fish seed is collected from the wild, it can also be mixed with that of other animals. But the lack of availability of good- quality seed is a big problem in fish farming.

What is composite fish culture system?

Composite fish culture is the process of rearing different species of fish in the same area or fish pond. Nearly, five or six different species are grown together in a single fish pond. This ensures complete utilization of food resources in the pond. Such a system increases the fish yield.

What are the advantages of composite fish culture?

An advantage of composite fish culture is that it increases the yield of fish. Nearly, five or six different species are grown together in a single fish pond. The survival rate of fish increases and their yield also increases without affecting the other species.

Why are fish stocked in the same pond?

In order to obtain high production per hector of water body, fast growing compatible species of fish of different feeding habits are stocked together in the same pond so that all its ecological niches are occupied by fishes. This system of pond management is called mixed fish farming or composite fish culture. It is also known as polyculture.

How does a mixed culture fish culture work?

The foods of the different layers in pond-water are fully utilized by the carps in the composite fish culture or mixed culture. Induced breeding can also be done in the exotic carps and they are fast growing and the total production of fishes is very high and cost of production is less; this is also a profitable one.
