| ABSTRACT The inshore shoals of basking sharks that appear in spring off the western seabord of Europe have been variously claimed to be part of a seasonal south to north migration, or local, perhaps nuptial, aggregations. The decline in the catches of the Achill Island Fishery in the last decade suggests that the size of the shoals has diminished there. Size/frequency analysis of available records shows a midsummer peak of specimens with a mean length of 3.09 m and a mid-winter peak at 3.52 m; the difference is significant and is ascribed to growth. From this value, coupled with the recorded maximum and minimum sizes, a hypothetical asymptotic growth-curve is calculated. Comparison of this age/length relationship with the observed relationship between... |
