Behavior and recruitment success in fish larvae: variation with growth rate and the batch effect
Predation-mortality risk for red drum (Sciaenops ocellatus) larvae does not appear to be related to their growth rate, but important differences in behavioral performance occur between batches of larvae. This conclusion is based upon field-enclosure and laboratory experiments that assessed the degre...
