Although there is no information presently available to unequivocally determine the origin of the recruits, the relationship between epifaunal diversity and recruitment could be partially explained by the life history characteristics of organisms within these assemblages.
Within epifaunal communities, reductions in biomass, secondary production, and species diversity have frequently been associated with increased fishing disturbance (Hiddink et al.
Auster (2005) also reached similar conclusions by finding no significant difference in the density of a common rockfish species (Sebastes fasiatus) between areas of rock and boulders with dense coral cover and similar areas having dense epifaunal cover (i.
The behavior of at least one infaunal predator, Glycera alba, suggests that it uses mechanoreceptors for prey localization and vibrational signals as the information source (Ockelmann and Vahl, 1970); other epifaunal predators are also known to be sensitive to such signals (fish: Janssen, 1990; Karlsen, 1992; shorebirds: Piersma et al.

Such failure could result from any of the following events or conditions: mechanical failure of a critical tag component; destruction by fishing crews unaware of or not participating in the present research; excessive epifaunal growth that makes the tag negatively buoyant or prevents the tag from floating with the antenna in a vertical position; or fouling of the tag on the fish, fishing gear, or flotsam.
