Commercial shrimp farms located throughout the world utilise several techniques to harvest shrimp from ponds and raceways. Commonly, farmers drain their systems and collect shrimp in nets, mesh bags or baskets as water passes through the drain. Other methods for partial harvest include cast netting or trapping the shrimp as water exits the pond gates during receding tides. Recently, modified mechanical pumps have proven to be very effective at harvesting shrimp from ponds and raceways.
Some commercial farms now use mechanical pumps to reduce the time and labour required to harvest. Farms that sell to certain high-end markets are often unable to use collection methods involving nets, mesh bags or baskets because the shrimp can be damaged during harvest.
At the University of Florida shrimp demonstration facility, protocols have been established for effective use of a fish pump to harvest juvenile and adult Pacific white shrimp, Litopenaeus vannamei, from ponds and raceways. These protocols can reduce time and labour costs, improve product quality, and can be used with other aquatic organisms.
