A Case Study on Feed Management to Improving Production and Economic Returns for the Semi-Intensive Pond Production of Litopenaeus vannamei por Allen Davis, D., Amaya, Elkin, Venero, Jesus, Zelaya, Oscar, B. Rouse, David

“…It is also quite interesting to note that almost allmanagement set points (e.g. poor growth, or good growth) result in increases in feed input and that most often oneof the lowest payed employee is responsible for the proper application of the most costly component of shrimpculture, (i.e. the feed). Over the last six years, research at the Claude Petite Mariculture Center has been conductedusing standardized operational protocols (35 shrimp/meter, 10 hp/ha of base aeration, limited water exchange) whileachieving a systematic improvement in feed management. …”
