Paddlefish Polyodon spathula polyculture with freshwater shrimp Macrobrachium rosenbergii.

摘要

Several Kentucky farmers have adopted low-input shrimp farming over the past few years. While inorganic fertilization is optional, organic fertilization with alfalfa pellets is central to this practice. The use of organic fertilization augments overall pond productivity. Increasing pond productivity ensures that a wide variety of natural food items, including zooplankton, chironomids, nema-todes and organisms colonizing detritus are available to shrimp at the beginning of the production season (Wurts 2004). This is especially beneficial for newly stocked juveniles because it provides an ample supply of high nutrient foods, assuring that shrimp have plenty to eat at the outset
