During the spring of 1967, 240,000 striped bass and striped bass X white bass hybrid fry were stocked in four one-acre dirt ponds. Each pond received 30,000 striped bass and 30,000 hybrids. At the end of a 71-day period, approximately 23,187 were harvested in three ponds, 12.88 percent of ,the original number. A total kill occurred in the fourth pond one week prior to harvest. Results indicate the hybrid having faster growth and higher survival rates.
