1 Pompano Jazmine Pritchett 7/10/13 Marine Aquaculture

2 Trachinotus carolinus (Florida Pompano)* Trachinotus Ovatus ( Golden Pompano) Trachinotus blochii (Silver Pompano)

3 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.

4 Pompano egg prior to spawning Fertilized Pompano egg (Neurula Stage) -eggs are buoyant, transparent and about 1 mm in diameter Larval stage of the pompano fish -Newly hatched will be 2.0 to 2.3 mm long with little pigmentation. Juvenile stage of the pompano -16 days after hatching

5 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.

6 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

7 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.

8 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.

9 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.

10 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
