Rice Fish water culture might be practiced to enhance the income of agriculturists and to make a fundamental thing accessible in the eating routine of people living in rural regions where this culture is the staple ration. As rice development requires a lot of water and fish culture likewise require water for fish life, this combination is valuable for both. Fish feast upon creatures which develop in fields and on numerous poisonous creepy crawlies and their hatchling, subsequently the product can be saved from hurtful creatures and better yield of rice can be obtained. The weed development can be controlled to a significant by refined herbivorous fish. It is conceivable to governor the development of molluscs and rearing of mosquitoes, where there is legitimate water management therefore diminishing general wellbeing dangers (Health hazards)
It requires low inputs and gives off-season work to farm workers. The upsides of this shared combination includes tillering in rice by the development of fish in immersed fields of rice, which outputs the greater production of rice. More noteworthy if profundity of water is managed in the fields, keeps bugs such as rodents from delving gaps in bunds. Notwithstanding welfares, these cultures involve increase in budget for agriculturists, especially in labour and other management, that may effectively be overwhelmed by fish farming revenue.
Types of rice-field water culture which are practiced are as follow: the first involves the raising of at least one crop of fish by utilizing rice fields, flooded with water after harvest. Other culture is developing fish alongside rice and at the finish of the rice-production season harvesting rice and fish. The next type includes trading the stock to bizarrely arranged dump, channels or pools at the season of rice harvest, and restocking them in fields for a further creating period. By this structure, fish is created to a larger size than is promising in the short term of a rice crop.
The fields of rice filled with fresh water are refined with mono-or poly-culture of finfish. The temperature of water and oxygen content for fish must be maintained by appropriate management of water. The bunds around the field must be reinforced and the altitude expanded on account of this culture and make them water tight by inserting straw along dividers of the bund. For culturing of species and the requirement of water level, a height of 20 to 60 cm is appropriate. Typically, the pipes and screens are used at inlets and outlets to avoid outflow of fish and entrance of other unwanted creatures. For the shelter of fish trenches are burrowed to fill in, when water gets cold or warm in field. A 50 centimeter width and a profundity of 30 centimeters are enough, yet for extraordinary conditions of temperature further trenches up to 100 centimeters are prescribed. And a slant of 30-45 degrees at side might be important depending on the soil type.
Connecting few components of production drops the hazard quota which agriculture involves. On the off chance that one component falls flat, the other can convey the minimum amount for survival. In fish cultivating, the essential yield is rice and thusly fish cultivating techniques must be changed to influence them to culminate with rice development. Water supply restricted areas may produce a noteworthy impede. Water quality in fields must be kept up at a level appropriate for fish and its nourishment. A major issue which has influenced the way of life, and decreases it in numerous states, is the unnecessary pesticides usage which murders fish. Likewise, there is a danger of accumulation of pesticides in fish which may be unsafe for users.
The risks in the small scale farming may be reduced by this joined culture as water used in the pond not only produces fish but it also contributes to the irrigation requirements of rice crop thereby increasing production as well as decreasing the production cost. The production from fish culture can be treated as a commodity point. It provides protein for mankind consumption. On the other hand, cash can be obtained by its marketing and farmer can fulfill its everyday needs. This technique of farming rises the farmer income hence farmer can live a better life.
