Heftier et at: Variability in abundance of larval fishes inside Beaufort Inlet

ferent species implies that care must be taken in the 
interpretation of correlations between these variables 
and fish densities. For example, temperature may 
be inappropriate to associate with observed densi- 
ties owing to the spawning-season periodicities in- 
volved with life history strategies of each species. 
Time of spawning (e.g. early winter) and the arrival 
at the inlet after a 2-3 month cross-shelf transport 
time, could result in higher abundance correspond- 
ing with rising temperatures. The multiple-regres-
