Abalone farming system

Year	Description
1993	Invention patented by Richard K. Craig and Benjamin E. Beede on May 6th, 1993. Abstract: An abalone farming system includes an indoor hatchery and an out-of-doors growout area which each utilize a plurality of horizontally elongated tanks in which the abalone are raised. These elongated tanks are stacked along a common vertical plane and arranged such that seawater provided at one end of an upper tank flows the entire length of that tank before cascading to a next lower adjacent tank, wherein the water flows the entire length of that tank before cascading to a next adjacent lower tank, and so forth until the water is discharged to a seawater discharge line. Each tank is provided with an air bar which extends the entire length thereof for aerating the seawater flowing through the tank, and a plurality of plates which are configured to increase the grazing area for the abalone and for dividing the area within the tank into distinct cells. A holding tank is utilized to supply water to both the hatchery and growout area. Water supplied from the holding tank to the hatchery is filtered, subjected to ultraviolet sterilization and temperature controlled. Seawater in the discharge line can be reclaimed and recirculated, thus permitting the abalone farming system to be modified into a partially closed loop system, if necessary.
