HOW TO USE THIS BOOK
Rabbitfishes possess well-developed, venomous dorsal
and anal fin spines. The first dorsal spine is small and projects
forward. Their venom can result in an extremely painful sting.
The rabbitfish species pictured here are subject to two separate
fisheries during their life. The first occurs when the youngest
stages (Manahac) recruit to the reef in seasonal runs at the time
of the moon's last quarter (quarto menguate) in April and May (and
occasionally later in the year). In some years they are harvested
in great quantities, while in other years the run is quite weak.
After a few days on shallow reef flats, Manahac adopt a herbivorous
diet. This stage is called Dage locally and is not highly
valued as food. The Dage continue to feed on algae and grow
over a period of months to the adult stage in which they spread
out over the reef in deeper waters and are again sought as foodfish.
Adults are harvested by spear, a variety of nets, and hook and line
using Enteromorpha seaweed as bait.
