Ozark Fisheries is one of the largest producers of goldfish and koi in North America. The family owned company took ownership of much of the previous Grassyfork Fisheries properties in 1970. At one time Grassyfork Fisheries produced 75% of the goldfish sold in the United States, earning Martinsville the moniker of the "Goldfish Capital of the World." The Martinsville location of Ozark Fisheries now serves as a production and shipping facility. Farm tours are available with prior arrangements for large groups. In fact, Ozark has hosted numerous groups in conjunction with the national FFA convention, held in nearby Indianapolis. Tours are $8 per person with a $100 minimum. Farm tours are rain or shine - with the majority of the Martinsville tour located indoors, modifications can be made to accommodate inclement weather. There is no official dress code, but the farm does recommend no open toed shoes. This is a hands-on tour of an aquaculture farm. Your group will be exposed to water and all things fish related. Sorry, tours are not available for individuals at this time.
