the actual volume of the distribution tank being used, the weight of fish 

 being transported, and the volume of water displaced by the fish. 



Table 40 provides the water displacements for various weights of fish. As 

 an example, what would be the loading density of 800 pounds of fish trans- 

 ported in a ,500-gallon tank?

TROUT AND SALMON 



Normal carrying capacity for 1.5-inch and 2.5-inch chinook salmon is 

 0.5-1.0, and 1.0-2.0 pounds per gallon, respectively. The carrying capacity 

 for 4-5-inch coho salmon is 2.0-3.0 pounds per gallon of water. 



Under ideal conditions, the maximum load of 8-11-inch rainbow trout is 

 2.5-3.5 pounds per gallon of water for 8 to 10 hours. Similar loading rates 

 are appropriate for brook, brown, and lake trout of the same size.
