Careful Monitoring, Often with Feed Trays, Increases Efficiency
Fertilization and Natural Productivity
- Semi-intensive production is the most commonly used technology level in freshwater prawn farming. At the beginning of the rearing period, when biomass densities are low, some semi-intensive farmers rely on organic and/or inorganic fertilization rather than feeding. Others find that providing feed from the beginning improves production and is cost-effective. Early in the produc…
Prepared Diets
- Although more expensive, some farmers prefer to feed a prepared diet throughout the production period. This feed acts both as a direct nutritional source and a fertilizer to enhance the availability of natural foods in rearing ponds. Initially, even nutritionally complete diets probably serve more as fertilizer than direct nutrition. Later, as the biomass density of the prawns increases and the a…
Feed Management
- Due to differences in feed types, stocking density, water chemistry and natural pond fertility, general recommendations for feeding rates are difficult to make. It is also difficult to calculate even reasonably accurate estimates of the total biomass of prawns in ponds due to the problematic sampling or seining of prawns. Generally, prawns are fed a fixed amount that depen…
Feeding Trays
- The best way to measure food consumption is by feeding trays that can be lifted out of the water for inspection. Lift nets or feed trays can be constructed by attaching any netting with a mesh small enough to retain the feed particles to a wooden or metal frame. The feed trays should be inspected every day before feeding to determine if there is any feed left over from the previous a…
Management Input
- Within the definition of semi-intensive production, there are many levels of management input, which can include the use of substrates, the ability to exchange water, and the level of aeration provided. For example, in the temperate U.S., most producers use full-time or nightly aeration and tend to feed at much higher rates than farmers in tropical countries. This is partly due to the nee…
