The plots of land to purchase for the aim of fish farming rely largely on how huge you want your farm to be. For instance: the sort of plan you have got for the extension. Nonetheless, nothing stops you from beginning with two fish ponds after which increase int the others.
The essence of having a minimum of two ponds for fish farming is to make sorting the fish straightforward, Due to this fact, to know the house wanted, the really useful stocking density of a fish within the pond is 10fish/m² which implies that you’ll need an space of 100m² for 1000 fishes. Now you can use this to decide what you need to start with and the expanse of land you’ll need to start it.
Applicable website choice in fish farming is one of a very powerful elements that decide the success of the fish farm. Earlier than building of the pond, the water retention capability of the soil and the soil fertility has to be taken care of as a result of these elements affect the response to the natural and inorganic fertilization within the farm pond.
The chosen website for fish farming ought to have sufficient water provide around the yr for pond filling and different makes use of. The pond building has to be primarily based on the topographic space. In swampy and marshy areas, bunds ought to have a better accumulation of soil to construct the pond of a preferable measurement. Self-draining ponds are perfect for increased elevation areas.
The fish farming website needs to be simply accessible by street or any kind of transport to attain the marketplace for straightforward fish disposal. As well as to this, the accessibility of inputs similar to feed, seed, fertilizer and the development materials must also be out there close by the location. The location needs to be free from air pollution, industrial waste, home waste and some other dangerous actions.
For, website choice the next ecological, organic and social elements need to be thought-about.

In website choice for a pond, the ecological elements to be thought-about embrace soil, water, topography and local weather.
The soil high quality influences the pond productiveness and water high quality and determines the dyke building. The properties of soil texture and soil permeability are decided to determine the suitability of a website. Pond backside ought to have the flexibility to maintain the water. Loamy, clay loamy and silt clay soil varieties are most fitted for pond building. high quality gravel mustn’t exceed 10 p.c. Thus the rocky, sandy, gravel and limestone soil varieties are to be averted.
Analysis of soil suitability
Soil suitability might be evaluated by three strategies.
- In squeeze technique, take the soil in moist hand and squeeze the soil by closing your hand firmly. If it holds its form even after opening the palm of your hand, soil is appropriate for pond building.
- The bottom water take a look at is the most effective technique to consider the soil suitability. Dig a pit of one-meter depth and canopy it with leaves for an evening. If the pit is crammed with floor water within the subsequent day morning then a pond may very well be constructed. Nonetheless, in such soils, drainage could require extra time due to the supply of enough groundwater. If the pit is empty the subsequent morning, the location is appropriate for pond building, however the water permeability has to be examined.
- The third technique is the water permeability take a look at. Pour the water into the pit and canopy with leaves. If no water is discovered within the pit on the subsequent day morning then there may be seepage. To substantiate this, as soon as once more pour the water into the pit and canopy it with leaves. If the water availability is excessive then the location is appropriate for building. But when the water is drained, the location will not be appropriate for pond building. Nonetheless, the location can be utilized by way of use of plastic or heavy clay to cowl pond backside.
For a profitable fish farming enterprise, an sufficient quantity of water is required to construct the fish farm as a result of water depth wants to be adjusted at common intervals. Pure water our bodies similar to reservoir, river, and lakes have secure water high quality parameters (Water temperature, dissolved oxygen, pH, alkalinity and water hardness) compared to borewell and effectively water.
The fish farming website needs to be away from the flood space. Water shouldn’t be acidic or alkaline and if discovered to be so, appropriate correction is to be achieved by making use of lime or natural manure respectively.
The perfect water temperature is 20 – 300C for a fish farm. Water Salinity is the quantity of salt dissolved in water. A couple of freshwater fishes similar to tilapia and catfishes develop even in salt water, however the carps can stand up to solely in freshwater.
Sort of fish farming pond building is decided by the land topography. Usually, flood inclined areas and poor rainfall areas need to be averted. Areas similar to industrial zones, fields with underground oil pipelines, irregular land space, fields with excessive electrical energy poles and radio masts and extremely rooted vegetation space are additionally not really useful for pond building.
Organic elements embrace the species to be cultured, seed supply and tradition sort and so they need to be thought-about earlier than website choice of farm.
Social and financial elements
The ecological and organic elements are a prerequisite for good practices in aquaculture website choice and website administration. Additionally it is necessary to get to know the social and financial background of the realm and perceive the tradition and traditions, significantly concepts and beliefs domestically related to aquaculture practices.
The social material, market, and its construction, providers instantly or not directly linked with aquaculture sector similar to transportation, storage, wholesale market points and many others are to be thought-about. The land recognized for farm needs to be with out authorized points and fish farming needs to be accepted by the native folks. Different elements embrace availability of labour, electrical energy, medical services, and transportation.
An clever design and format is a prerequisite for an environment friendly pond building for fish farming. The excavated earth needs to be used to assemble the dyke and with a plodding slope in the direction of the outlet for the right draining facility. Ideally building of fish farming pond has to be accomplished throughout summer season in order that the pond can be utilized for stocking.
