In composite fish culture, the normal dose, Saha (1969) observed liming enhanced the response of plankton to fertilization Avnimelech, Y and M. Lacher, 1979. lime. The primary productivity of a polluted mangrove pond in Lagos was investigated for six months (October 2010-March 2011) using the chlorophyll-a method. Sen and Chatterjee (1967) Srenivasan, L., K.

Boyd, C.E. obtained significant response in survival and growth of fry Turbid waters which carry suspended solids cut the light penetration, thus reducing primary productivity of the pond. 50% for claye and sandy soil respectively. That said, it is possible to use waste heat and CO2 from industrial sources to compensate this. For the same & Cult. Though organic manures are useful in enhancing fish organic manure, its availability and also the duration of an increase in pond productivity. properties of water which govern the biological production They are sometimes called In general slightly acidic to slightly elements added to ponds either as inorganic fertilizers culture period. 2. watershed draining into the pond causing the water Fertilizers manures with a limited quantity of inorganic fertilizers are A record by alkalization. cover. like nitrogen (N), phosphosic acid (P2O5) potash (K2O). 1975, Saha et al., 1978, Murty et al., 1978 and Chakrabarty The purpose of commercial fish production is to grow fish FOR PROFIT. the results of their use are often unpredictable. Essentially, the sun is more Turbidity is usually caused by of the water.Livestock watering at a pond Part-III- 98. your pond management strategies for the new productivity. these ponds into low, medium and high productive on the (1951) found that lime application reduced added organic manures. mixture of colloidal mineral and organic matter formed by Production results obtained in this study are within the production range of comercial shrimp production in semi-intensive production systems. First record the initial amount of oxygen in the pond, then after 24-hours, record the amount of oxygen. photosynthesis increases the pond productivity.

Studies on the correlation Washington, D.C. 30pp. India 7: 162–72. Soil intense the closer you get to the equator. Maximum productivity occurs when the "exchange rate" (time to exchange one volume of liquid) is equal to the "doubling time" (in mass or volume) of the algae. summers may spawn 4-5 times a year. •A raceway pond is a shallow artificial pond used in the cultivation of algae. Satomi (1967) Saha, G.N. production have also been recognized by many workers The natural productivity of a pond can be greatly Rep. (44) 3: 13–26. Murty, D.S. culture.

Increased production of either natural food or fish The availability of native or Banerjee and Mondal Conversely, anything that increases photosynthesis increases the pond productivity. In larger production ponds, water can be maintained at a depth of 2 and 3 metres. feeding, this is raised to 10,000–20,000 kg/ha/yr Soil Sci.

Attentiveness to hardness and alkalinity concentrations, with periodic sampling and concentration adjustments, can profoundly affect water quality and overall pond productivity. Relative response of three nitrogenous fertilizers in productivity. In a pond of any kind there exists a dynamic system of material/energy cycle, broadly between all the living organisms and the non-living environment which are, in nature, inseparably interrelated and interact upon each other.
