Study on the Development of the Prior Residence Effect in Rainbow Trout (Salmo gairdneri)
Hatchery-raised rainbow trout (Salmo gairdneri, Richardson) were placed singly in small aquarium tanks for varying periods of time before the addition of a second fish. The effect of prior residence upon dominance between two fish became evident after 12 hours or more had elapsed before the addition of the second fish. The resident was more likely than the intruder to attack first, attacked in a shorter time, and had a higher potential for final dominance. The results may be applicable to the estimation of the carrying capacity of natural waterways and artificial propagation enclosures.
