Summary of Squaliforme shark diet studies for species commonly caught during Chatham Rise bottom trawl surveys.

Unless specified otherwise, n is the number of stomachs that contained prey and so yielded diet information. Length is the approximate maximum total length, from McMillan et al. [55]. The term fish means both teleosts and elasmobranchs. The statistics are %N, percentage number; %W, percentage mass; %N, percentage number;%V, percentage volume; %O, percentage occurrence; Occurrence, presence absence and could not estimate %O; semi-quantitative, quantitative diet description but data not presented in detail (only in figures).1, numerous estimates were possible by area and year, but the estimated trophic level did not vary much from the estimated reported here because the diet variation was largely in the proportions of cephalopods and fish, which have similar trophic levels.2, estimates for 1980s, 1990s, and 2000s.3, estimates were possible for two size classes, but only one trophic level is reported as there was only 0.01 difference between the two.
