<meta content="Striped trumpeter larvae reared in algal cell-induced turbid water (greenwater) fed equally well
in clearwater in a light intensity range of 1–10 mol s1 m2, when evaluated in terms of both
the proportion of larvae feeding and larval feeding intensity. An ontogenetic improvement in
photopic visual sensitivity of larvae was indicated by improved feeding at 0·1 mol s1 m2,
from 265% of larvae feeding and 0·0270·005 rotifers consumed per feeding larva min1 on
day 8, to 962% and 0·2210·007 rotifers consumed larva1 min1 on day 23 post-hatching.
Algal cell-induced turbidity was shown to reduce incident irradiance with depth, indicated by
increasing coefficients of attenuation (1·4–33·1) with increasing cell densities (0–2106 cells
ml1), though light intensities in the feeding experiment test chambers, at the algal cell densities
tested, were within the optimal range for feeding (1–10 mol s1 m2). Algae-induced
turbidity had different effects on larval feeding response dependent upon the previous visual
environment of the larvae. Young larvae (day 9 post-hatching) reared in clearwater showed
decreased feeding capabilities with increasing turbidity, from 981% feeding and 0·1530·022
rotifers consumed larva1 min1 in clearwater to 6110% feeding and 0·0420·004 rotifers
consumed larva1 min1 at 56 NTU, while older clearwater reared larvae fed well at all
turbidities tested. Likewise, greenwater reared larvae had increased feeding capabilities in the
highest algal cell densities tested (32 and 66 NTU) compared with" name="eprints.abstract" />

in clearwater in a light intensity range of 1–10 mol s1 m2, when evaluated in terms of both
the proportion of larvae feeding and larval feeding intensity. An ontogenetic improvement in
photopic visual sensitivity of larvae was indicated by improved feeding at 0·1 mol s1 m2,
from 265% of larvae feeding and 0·0270·005 rotifers consumed per feeding larva min1 on
day 8, to 962% and 0·2210·007 rotifers consumed larva1 min1 on day 23 post-hatching.
Algal cell-induced turbidity was shown to reduce incident irradiance with depth, indicated by
increasing coefficients of attenuation (1·4–33·1) with increasing cell densities (0–2106 cells
ml1), though light intensities in the feeding experiment test chambers, at the algal cell densities
tested, were within the optimal range for feeding (1–10 mol s1 m2). Algae-induced
turbidity had different effects on larval feeding response dependent upon the previous visual
environment of the larvae. Young larvae (day 9 post-hatching) reared in clearwater showed
decreased feeding capabilities with increasing turbidity, from 981% feeding and 0·1530·022
rotifers consumed larva1 min1 in clearwater to 6110% feeding and 0·0420·004 rotifers
consumed larva1 min1 at 56 NTU, while older clearwater reared larvae fed well at all
turbidities tested. Likewise, greenwater reared larvae had increased feeding capabilities in the
highest algal cell densities tested (32 and 66 NTU) compared with</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Additional Information:</th><td valign="top" class="ep_row">The definitive version is available at www.blackwell-synergy.com
