ornamental fish reproduction and
of live feeds for marine ornamental fish
his B.S. in Marine Biology from Hawaii
Pacific University in the spring of 2002.
After a brief period with the Oregon
Department of Fish and Wildlife working in
fisheries science, he began working for the
Oregon State University Molluscan Broodstock
Program, where he was exposed to aquaculture
of the Pacific Oyster, Crassostrea gigas.
After a few years there, he began a position
in Cedar Key, FL with UF extension agent
Leslie Sturmer, where he focused on various
production aspects of the hard clam,
Mercenaria mercenaria. In 2009, he
received his M.S. in Fisheries and Aquatic
Sciences from the University of Florida
under Dr. Cortney Ohs. His thesis focused
on evaluating Florida pompano,
Trachinotus carolinus, larvae fed
nauplii of the calanoid copepod
Pseudodiaptomus pelagicus. Eric joined
the Tropical Aquaculture Laboratory in
October 2010 as a part of a new project
exploring the production of marine
ornamental fish species.
the use and production of alternative live
feeds for first feeding marine ornamental
in the production of marine ornamental fish
is the first feeding phase, when larvae
begin feeding exogenously. Most marine fish
species are provided rotifers (Brachionus
spp.) and/or brine shrimp (Artemia
spp.) nauplii during this phase. However,
they are not the preferred prey of most
marine fish larvae and success with them has
been limited to a few species. Using this
feeding regime, larvae exhibiting a
generalist feeding mode tend to have
suitable performance; however, a number of
marine fish larvae feed selectively.
Copepods and other marine zooplankton
typically yield better performance of larvae
during experimental trials. The problem
lies in producing sufficient numbers of
these organisms to satisfy the needs of
commercial facilities. Furthermore, using
wild marine zooplankton can be inconsistent
and problematic for commercial hatcheries.
Expanding the number of marine ornamental
fish species in commercial production relies
upon looking beyond the readily available
live feeds and exploring the numerous
phytoplankton and zooplankton available.
Alternative live feeds organisms, including
copepods, dinoflagellates, ciliates,
appendicularian larvae, nudibranch
trochophores, and bivalve larvae, all have
potential for use and production as a live
feed in marine fish larivculture.
