TRANSPORT OF FISHES 83 



removable lid that rests upon flanges extending 

 around the inside of the tank. A good seal is assured 

 by use of a sponge rubber gasket on the flange, and 

 clamps to hold the lid firmly in place. A hole is cut in 

 the center of the lid to accommodate a 12-volt agi- 

 tator. The agitator is energized by an extension cord 

 wired to the automobile battery. For distances of 300 

 to 400 miles it will carry approximately one pound of 

 fish per gallon. The unit described would have a 

 capacity of approximately 30 gallons. At one pound of 

 fish per gallon it would transport 27 pounds of fish. 

 For transporting fishes up to 4 inches in length four 

 perforated aluminum insert cans are used to facilitate 

 handling the fish. When hauling larger fishes the unit 

 can be used without the insert cans. For this type unit 

 ice can be used for lowering or maintaining a low 

 temperature. Anesthetics and buffer can also be used 

 as described above. 



A larger unit of this same type can be adapted to 

 transport by a pick-up truck. The unit illustrated in 

 Figure 8 has a capacity of approximately 135 gallons. 

 Thus at one pound per gallon it has a capacity of 

 approximately 120 pounds of fish. This tank may also 

 be equipped with insert cans. Such a unit is large 

 enough to warrant filtration which would be possible 

 with the addition of a self -priming, centrifugal pump 

 with a suction line attached to the drain of the tank 

 and spray jets installed in the top of the tank. A 

 swimming pool type filter could be installed in the 

 pressure line. It would still be desirable to retain the 

 12-volt agitator, however.
