catfish will safely hold 2 pounds of 8- inch, or 4 pounds of 16-inch fish per 

 gallon of water. 



(4) If the transportation time exceeds 12 hours, the loading rate should 

 be decreased by 25"n. 



(5) If the transportation time exceeds 16 hours, loading rates should be 

 decreased by 50% or a complete water change should be arranged. 



(6) During the winter, hauling temperatures of 45-50°F are preferred, 

 whereas 60-70°F are preferable during summer months. 



LARGEMOUTH BASS, BLUEGILL, AND OTHER CENTRARCHIDS 



In keeping with current stocking requirements, centrarchids are transport- 

 ed primarily as small fingerlings at light densities (Table 42). 



Largemouth bass fingerlings of 6-10 inches can be transported at 2.0 

 pounds per gallon of water for up to 10 hours without loss. This loading 

 rate was used when several southwestern hatcheries transported larger 

 largemouth bass fingerlings and most trips were considered highly success- 

 ful. Aeration was provided by aerators and bottled oxygen introduced at 

 0.14—0.21 cubic foot per minute. 



STRIPED BASS 



The Fish and Wildlife Service in the southeastern United States hauled 

 striped bass averaging 1,000 per pound at a rate of 0.15 pounds per gallon 

 of water for up to 10 hours with few problems. Fingerlings averaging five 

 per pound were transported at rates of 1.5 pounds per gallon for 10 hours 

 and 0.75 pounds per gallon for 15 hours. Recirculation systems and agita- 

 tors both have been used successfully. The recommended water tempera- 

 ture for hauling striped bass is 55°-65°F. Successful short hauls have been 

 made at higher temperatures. 



Striped bass averaging 500 per pound have been successfully transported 

 at loadings approaching 0.5 pound per gallon for periods of 19 to 24 hours.
