  1. Pompano Jazmine Pritchett 7/10/13 Marine Aquaculture

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

  3. Economic Importance • 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. Life Cycle 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

  5. Reproduction • 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. Feeds • 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. Production Methods • 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. Water Chemistry & Culture requirements • 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. Advantages Disadvantages • 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
