Answer: Option (d) all of these is correct
Explanation:
Water supply
Ensuring an adequate supply of water in the right quantity and quality is the most important factor to consider when deciding the suitability of a fishpond site. Therefore, investigation of suitable water sources should be carried out more thoroughly during site selection. A statement from the irrigation department or other water authority must be obtained regarding the amount of water required for the pond or hatchery, and any restrictions on the water supply to the fish farm (e.g.: maintenance time in irrigation canal).
Climate
The key climatic factors obtained from the nearest weather station are:
- average monthly temperature
- average monthly precipitation
- average evaporation monthly
- average monthly humidity
- average monthly sunshine
- average monthly wind speed and direction
Land
Confirm that the proposed area is suitable. The general shape of the terrain should have a slope of no more than 2 percent. If a wasteland, unsuitable for agriculture or other direct uses, is selected for a project, the cost of the land will be low. Soil elevation and floodwater levels are important factors in determining whether an area is suitable for a fish farm or hatchery. The soil is not deeply waterlogged; The maximum flood water level in the last 10 years does not exceed the top of the dyke.
