Interpretive Summary:

Technical Abstract: Golden shiners (Notemigonus crysoleucas) are the major species of the baitfish transported and sold in the United States. Basic data of ammonia excretion rates of golden shiners is critical for live transport practice and rational design of improved live transport systems. To simulate live hauling conditions, ammonia excretion rates of N. crysoleucas at 15, 20 and 25 C were determined for a 24 hr period in three recirculating systems after fingerling N. crysoleucas were fasted and acclimated for 2 days. The experiment was repeated four times using different size and batches of shiners. Results indicated no significant differences in the hourly ammonia excretion rates (HAER) between two batches of equal size golden shiners. However, with fish unit size increasing from 2.7 g to 3.6 g, HAERs significantly decreased and with increasing temperature from 15to 25 C. HAERs increased, respectively. Maximum value of average daily ammonia excretion rates at three temperatures was applied to calculate the size of floating bead biofilter (FBF) or zeolite filter needed for one hauling vat (378.5 L water, 63.5 kg fish) for 24 hrs. Considering the limitations of temperature, salinity and the operational feasibility, zeolite filter is more practical than FBFs for live fish transport.
