Pentair Aquatic Eco-Systems’ World Aquaculture Technology Engineering & Research (W.A.T.E.R.) Center Successfully Completes First Fish Harvest

On Friday February 5th, the team at Pentair’s PAES W.A.T.E.R. (World Aquaculture Technology Engineering and Research) center conducted the first fish harvest from the 12,500 sq. ft. indoor aquaculture operation. A team of eight Pentair employees worked diligently to ensure complete success on this project. In total, 10,564 lbs. of tilapia were transferred from Pentair’s indoor Recirculating Aquaculture System (RAS) to tanks on the live fish hauling truck. When the truck arrived, the first hour was spent loading clean water into the hauling tanks to ensure the fish had a healthy environment while being transported.

Fish were harvested from the tanks with seafood baskets and transferred to the truck in tanks of water, important in maintaining product quality, keeping them calm to reduce damage and loss of scales on themselves or other fish being transferred.

This cohort of fish, the first grow-out from the PAES W.A.T.E.R. facility, was grown for 242 days from fingerlings of 0.73 grams to approximately 682 grams (1.5 pounds) each. They were then held on a maintenance diet – a technique where fish are fed an amount which keeps them healthy but does not encourage growth. The survival rate of this cohort was much higher than anticipated. Initial planning, purchasing, and stocking numbers anticipated a ten percent mortality rate during the overall growout period; our mortality rate, however, was just over one percent—much better survival than anticipated   

When the buyer sets a pickup date, the fish are purged for one week prior to being transferred from PAES W.A.T.E.R. – located just outside of Orlando, FL – to New York City, arriving in the evening of February 6th. On the way to their final destination, the truck stopped in North Carolina for a water exchange to ensure the well-being and quality of the animals.

The Lunar New Year holiday on Monday February 8th results in an increased demand for fish. Considering the current shortage of seafood available for purchase, providing these healthy, delicious, farm-raised fish to the live fish market was well-timed. The team working at PAES W.A.T.E.R. looks forward to similar events like this in the future.
