Farming freshwater prawns

FIGURE59 cont.CROSS SECTIONSOURCE: EMANUELA D’ANTONI6.2 Management of the grow-out phaseThis section of the manual briefly introduces some general principles of aquaculture farmmanagement. In doing so, it draws heavily upon some other FAO manuals on the managementof ponds and water (FAO 1996) and fish (FAO 1998). A simple manual on small-scalefreshwater fish farming (FAO 1994) is also available. You are strongly recommended toobtain and read these publications before commencing operations on your prawn farm.This section of this manual concentrates on matters which are specific to the managementof freshwater prawn farming and is based on the original FAO manual on this topic, supplementedwith material extracted from Boyd and Zimmermann (2000), D’Abramo andNew (2000), Johnson and Bueno (2000), Karplus, Malecha and Sagi (2000), Tidwell andD’Abramo (2000), Valenti and New (2000) and Zimmermann and New (2000). Informationis provided on the management of the monoculture of freshwater prawns (at various levelsof intensity in different climatic zones), as well as their polyculture with other aquaticspecies and its integration with other types of farming. Harvesting is dealt with later, in aseparate section.Figure 60Long-tail pumps areeasily available inThailandFigure 61Long-tail pumpbeing used to liftwater from a Thaiirrigation canal into asupply channel forfreshwater prawnponds (this type ofpump can also beused to drain pondsby pumping)SOURCE: HASSANAI KONGKEOSOURCE: HASSANAI KONGKEOCHAPTER 699
