Farming in Unison
At Marrian Fishes, we view farming differently than what consumers generally perceive it to be: not just a series of isolated activities to produce food, but an integrative process which aims at maximum productivity with an emphasis on zero wastage.
Crop production and livestock/fish rearing take place in harmony. Ammonia and Nitrate-rich waste sludge water is released to the well system, to be further utilised for agricultural purposes in the farm. The sludge also serves as a bio fertilizer for plants, reducing the need for additional fertilizer. Waste produced after the cleaning of fish, is added to a unique vermicompost system - used as manure for plants.
Pond liner is used to convert a natural pond into an artificial pond in order to increase the stocking density of the fishes. Pond liners need to be protected from sharp objects (for example, stones) below the liner and from being punctured by any objects in the water body. Protection can be provided with layers of sand, geotextiles (particularly needle-punched nonwovens) and other materials. Pond liners are manufactured in rolls or accordion-folded on pallets. When deployed in the field their edges and ends are overlapped and seamed together. Methods used to seam the pond liners are thermal fusion, solvents, adhesives and tapes.
Sludge is a common problem for pond owners which unfortunately cannot be avoided. Pond sludge is made up of the organic materials that are found in and around your pond. Ranging from fish food, faeces and plant debris, it is the end product of when all of this matter falls to the bottom of your pond and begins to rot. Preventing or at least by minimising the amount of sludge is easy to do and will keep your pond running efficiently.
2HP Paddle Wheel Aerator - STD - B24 is specially design for extensive & modified extensive Shrimp/ Prawn & Fish Aqua Culture. It helps to increase DO concentration during pond culture & it also helps for removed temperature stratification in the daytime and eliminated oxygen gradient in the nighttime.
Where oxygen is injected into the water flowing in a tube at a given point, the efficiency of oxygen dissolving depends on the time the oxygen stays in the pipeline and on the pressure in the tube. Oxygen can be fed into the pipeline through an external pipe which helps in sucking the atmospheric air and is injected in to the water at a level of about 1m below the water level.
Blower with diffusers
During air diffusion, the air is supplied by various types of compressors or blowers into the water where it is diffused through a variety of diffusers. When the air is diffused through a perforated pipe large bubbles of up to 10 mm in diameter are formed and when the diffuser is a porous material fine bubbles of 2-5 mm in diameter are produced. When the bubbles emerge and pass up to the water surface a part of their oxygen content is dissolved in the water, and also a secondary upwards water movement is generated, creating a mixing effect.
Bird liners are set to protect the fish from the attack of birds like crane, kingfisher, kite etc. These bird liners are made of nylon monofilament twines, are laid and tied across the opposite sides of the pond at a distance of 5 inches between adjacent twines. It is of the red colour which is visible for the birds from far distance.
The main aim of bio fencing is to prevent the hunting and poaching of fishes by humans or by any other means. Bio fencing is done by the help of a 10ft height green net around the fence of the pond, connecting the top end of the green net to the bird liner and the bottom end below the mud. A door and a lock is provided at one end of the bio fencing to facilitate the feeding and movement inside the pond.
Water in the pond gets contaminated by the continuous accumulation of the sludge at the bottom of the pond. The sludge needs to be periodically removed in order to prevent the ammonia formation that is caused by the sludge accumulation. Once sludge water is removed from the bottom of the pond fresh water needs to be added to the pond inorder to keep the water replace the water removed through sludge.
