| Abstract: | The relationship between otolith radius and fish length in the pilchard Sardinops ocellata off South West Africa is shown to vary seasonally. This phenomenon may explain the sinuous nature of the relationships between body part and fish length in other studies. The seasonal variation is too large to be accounted for solely by ingrowth of the hyaline ring by opaque material. The otolith radius: fish length ratio shows a weak negative correlation with fish growth rate (r = ?0,7547, p = 0,1–0,05). |
