Figure 6.— Three annual cycles that relate to the condition of Pacific herring in the vicinity of 

 Auke Bay, AK: A visual index of visceral fat (see text); gonad indices based on (wet) gonad weights 

 as a percentage of the eviscerated (wet) body weights that would be expected at various BL's (see 

 Figure 4); and an annual cycle of zooplankton density, from displacement volumes for 1962-64 given 

 in Wing and Reid (1972). Points based on less than five specimens are enclosed in parentheses. 

 Curves fit by eye.
