Average abundance, measured as number of individuals per grouper pit, of large fish, including large grunts such as the margate (Haemulon album) and cottonwick (Haemulon melanurum), snapper (Lutjanus spp.), grouper (Mycteroperca spp, Epinephelus spp., and the graysby
, Cephalopholis cruentata), triggerfish (Balistes spp.), and the hogfish (Lachnolaimus maximus), associated with grouper pits surveyed during 2012-2015 off southwestern Florida, shown for each predator presence or absence category: no predator; red grouper (.Epinephelus morio) only; species of lionfish (Pterois spp.) only; or both predators.
Graysby were the most abundant group of larvae collected in the Gulf of Mexico that could be identified to species.
Similarly, larval graysby were rarely collected before 1995 (occurring in 2 of the 10 years between 1986 and 1995), but they have become more common in samples during recent decades (7 of the 10 years between 1996 and 2005) and are often collected in multiple months within a year.
Graysby are considered fall spawners throughout their range (Richards et al., 2005), and most graysby larvae were collected during July-October in shallow shelf waters on the west Florida Shelf (mean depth of 49.2 m vs.
However in the Straits of Florida, flexion and post-flexion larval graysby were collected farther offshore than were preflexion larvae of the species (Fig.
The relative increase in occurrence of fall-spawned larvae was best illustrated by the rapid rise in the number of larval graysby collected.
For example, graysby larvae were one of the most abundant grouper species in our Straits of Florida collections and have become common in SEAMAP collections since 1995.
