Jerry Pixley, Farm Production Adviser


Self-taught shrimp farming entrepreneur

Experience & Achievements

2001 – Rented his first farm and began raising monodon (Tiger Prawns). Trained himself in all aspect of shrimp farming, from pond-preparation to harvest.

2002 – Increased farm size and became one of the first to start raising vannamei in Phang Nga, Thailand. Established protocols through trial and error, attaining 95% survival and producing 15 tons per hectare of 50-count shrimp.

2003-2004 – Rented and bought additional farm land, excavating the ponds and refurbishing the infrastructure, creating a top-notch farm.

2004-2010 – JRPixley Co consistently shipped between 200 and 250 tons per year.

2011 – White feces hit Southern Thailand and production fell. However, JRPixley Co quickly recovered through the use of probiotics and improved water quality, returning to previous production levels.

2012 – EMS began affecting Thai farmers. Over a year-and-a-half period, JRPixley experimented with nursery ponds and developed a management program allowing them to remain profitable.

2014 – With the use of probiotics, careful water-exchange management, and with the combination of high-quality PLs, production was further improved with both monodon and vannamei. Good results were obtained, in particular, with monodon, producing 10 tons per hectare at 23-33g size, in 93-100 days, with 96% survival and 1.2-1.4 FCR.

By being proactive, and through adaptation, JRPixley Co never went out of production and always maintained a profit. Jerry has “sold the farm” and will return to the United States, but, is interested to remain active in shrimp farming in the US, or assisting in the start-up and operation of ventures elsewhere.
