Summary: 404
AbstractLight traps and channel
nets are fixed-position devices that in
volve active and passive sampling, re
spectively, in the collection of settle
ment-stage larvae of coral-reef fishes.
We compared the abundance, taxo
nomic composition, and size of such
larvae caught by each device deployed
simultaneously near two sites that dif
fered substantially in current velocity.
Light traps were more selective taxo
nomically, and the two sampling de
vices differed significantly in the abun
dance but not size of taxa caught. Most
importantly, light traps and channel
nets differed greatly in their catch
efficiency between sites: light traps
were ineffective in collecting larvae
at the relatively high-current site,
