  324. in clearwater in a light intensity range of 1–10 mol s1 m2, when evaluated in terms of both&#13;
  325. the proportion of larvae feeding and larval feeding intensity. An ontogenetic improvement in&#13;
  326. photopic visual sensitivity of larvae was indicated by improved feeding at 0·1 mol s1 m2,&#13;
  327. from 265% of larvae feeding and 0·0270·005 rotifers consumed per feeding larva min1 on&#13;
  328. day 8, to 962% and 0·2210·007 rotifers consumed larva1 min1 on day 23 post-hatching.&#13;
  329. Algal cell-induced turbidity was shown to reduce incident irradiance with depth, indicated by&#13;
  330. increasing coefficients of attenuation (1·4–33·1) with increasing cell densities (0–2106 cells&#13;
  331. ml1), though light intensities in the feeding experiment test chambers, at the algal cell densities&#13;
  332. tested, were within the optimal range for feeding (1–10 mol s1 m2). Algae-induced&#13;
  333. turbidity had different effects on larval feeding response dependent upon the previous visual&#13;
  334. environment of the larvae. Young larvae (day 9 post-hatching) reared in clearwater showed&#13;
  335. decreased feeding capabilities with increasing turbidity, from 981% feeding and 0·1530·022&#13;
  336. rotifers consumed larva1 min1 in clearwater to 6110% feeding and 0·0420·004 rotifers&#13;
  337. consumed larva1 min1 at 56 NTU, while older clearwater reared larvae fed well at all&#13;
  338. turbidities tested. Likewise, greenwater reared larvae had increased feeding capabilities in the&#13;
