Trachinotus carolinus (Florida Pompano)*
Trachinotus Ovatus (Golden Pompano)
Trachinotus blochii (Silver Pompano)
• Florida Pompano serves as an important sport and commercial
fishing species
• In the US Florida Pompano typically sells for $6 to $10 per
pound. In Hong Kong its priced at $5/Kg
• Very popular around several countries in Asia especially China
from which we import golden Pompano to help meet our
Florida pompano demands.
• Silver and Golden Pompano are produced heavily in Vietnam,
Taiwan, Singapore the Philippines, and Malaysia.
Juvenile stage of the pompano
-16 days after hatching
Larval stage of the pompano fish
-Newly hatched will be 2.0 to 2.3 mm
long with little pigmentation.
Fertilized Pompano egg (Neurula Stage)
-eggs are buoyant, transparent and
about 1 mm in diameter
Pompano egg prior to spawning
• Pompano undergo natural spawning during spring and early summer.
• In aquaculture systems spawning is hormone induced within the
brookstock year around.
-Fish are injected with a 76ug pellet of gnRHa to induce spawning
-Hatch rate falls between 70-95%
• Some culture systems will purchase juveniles from established
hatcheries for the grow out phase.
• Early larval stages are fed an enriched feed of rotifers.
• Between 7 to 11 days after hatching artemia enriched feed
replaces the rotifers.
• Artemia feed is discontinued 20 days after hatch.
• Commercial feeds are used for juvenile pompano fish in
the transition stage of development.
• During the grow out phase commercial feeds are still
utilized or they can be fed with “trash fish”
-47% crude protein & 15% crude fat feed for 50g fish
-43% crude protein & 12% crude fat feed for >50g fish
1) Pond & Recirculating Aquaculture Systems
-RAS used for the nursery stage and larviculture in hatcheries
of pompano
- Ponds are the least cost method compared to RAS and Sea
cages
- Ponds had no artificial food implanted and very little
human interference during the grow out phase.
2) Sea water Cages (for silver and golden Pompano)
- Fingerlings for grow- out are provided by hatcheries
to the sea cages
- Cages are placed in calm, protected warm waters
such as coves, bays or sheltered lagoons
- Cage site must have a good source of water exchange
to maintain water quality
- Nursery net cages made of B-net
- Grow out net cages P.E knotted net with a mesh size
of 14 cm.
• Temperature- 27 to 30 degrees Celsius
• Salinity- 30 to 37 ppt for adults. As low as 9 ppt and as high as
50 ppt for juveniles
• DO- between 5.5 and 8.0 ppm
• Depth- 5 to 7.5m
• Very adaptable to changing levels within the system except for
temperature.
• Fast growing
• Hardy
• Tolerance for low salinity
water
• Different sizes can be
placed in the same
ponds because
cannibalism is rare
• Can be fed “trash fish”
• Desirable for food
• Readily adapts
• Stock must be obtained
from along sandy beaches
or hatcheries at present
time.
• Little information is known
about many aspects of the
pompano
• Problematic production of
juveniles
