What are the symbiotic relationship between rice and fish in rice-fish culture?
Why have rice-fish system? Rice-fish systems allow the production of fish and other aquatic animals, from the same rice field area and generally without causing reductions in rice yields. This source of animal protein may be important for household nutrition and farm income.
How is fish benefited from the rice plant?
Rice-fish symbiotic relation Rice and fish form a mutualistic symbiosis — in other words, they both benefit from growing in the same ecosystem. The rice provides the fish with a shelter as well as providing shade and, in turn, reducing water temperature, which creates a more suitable environment.
How does rice-fish farming work?
Farmers plant their rice and put juvenile fish into the trenches. Once the rice is established the fish are let into the rice fields where they grow until harvest time, when the water is drained and the fish collected. The fish don’t just protect rice health, but human health too.
How is rice-fish farming sustainable?
Rice-fish farming is an excellent example of a sustainable approach to increasing food supplies as it does not involve any artificial fertiliser or pesticide. Also, it does not require expensive equipment or external expertise. It is also not harmful to the environment.
Which of the following is an advantage of placing fish in flooded rice fields?
Flooded rice fields awaken dormant plankton in the soil, insects flourish on the plankton, and the fish dine on both. In turn, the fishes’ presence reduces insects, weeds, and diseases that may harm rice.
Why is fish conservation important?
… They play a role in water purification, flood mitigation, sediment deposition, nutrient cycling, food production, providing habitat and maintaining biodiversity (WWF, 2006). Fish is the primary protein source for one 6 th of the entire human population, especially in developing regions (Helfman, 2007) .
Why is rice fish farming good?
Keeping fish in rice fields can increase rice yields by up to 10% – plus they have the additional supplies of fish. A diet of fish is an excellent source of protein and so improves people’s health. Extra rice yields, meanwhile, not only put meals on tables but enable families to sell surplus food at market.
What type of fish is produced in rice farming?

How did the rice fish get its name?
This similarity has led many killie keepers to also seek out and work with the various species. They are called ricefish because they are often found in the shallow flooded rice paddies throughout their range.
What do you feed a rice fish to breed?
If you want to breed them, however, it is important to improve this diet just a bit by offering live foods, such as daphnia, newly hatched brine shrimp, fruit flies, and/or Grindal worms, for several days. Other live foods, if available, are greedily taken as well. Adults of most species are easy to sex.
What should the temperature be in a ricefish tank?
