“But Dr. K....

What else is there??”

slide5

Ornamentals

“Feel good” fish!

introduction
Introduction
  • Aquarium trade a rapidly growing sector of aquaculture.
  • Approximately $15 billion industry (Bartely 2000).
  • High demand drives industry ($$$).
  • Several pros and cons concerning this industry.
slide9

Making fish makes money!

ornamental fish
Ornamental Fish
  • Influence of capture fisheries still applies.
  • As restrictions on animal collection

intensify, culture of ornamental fish

(OF) will assume a larger roll.

  • Currently, 90% of aquarium freshwater

fish cultured. (Reverse for marine fish—major issue!)

ornamental fish1
Ornamental Fish
  • Production of OF is a global industry with global impacts (globalization = bad news?)
  • Has accounted for 40-60% of total exports in Singapore, Brazil, Phillipines (Tay, 1977; Chao 1997; Dowd and Tlusty 2000; Baquero).
  • However, this has all been at the EXPENSE of the capture industry!

Ornamental Fish
  • Production of OF doubled between 1985-1997.
  • In U.S., OF production is ranked fourth behind catfish, trout, and salmon; 7% of total aquacultural production (JSA, 1999).
  • Florida produces over 800 varieties of freshwater ornamental fish through captive breeding accounting for nearly 80% of total U.S. value (FASS 1999).
  • U.S. demand accounts for ~60% of total industry!

Ornamental Fish
  • Lucrative industry (average value $35-60/lb.; marine even higher at $400-600/lb.)
  • Captive breeding of marine fish accounts for much less (~13% of marine fish traded are cultured, 3% commercially feasible (Dawes 1998; Schiemer 2001).

Ornamental Fish
  • Greed has led to habitat destruction.
    • - Mangrove destruction, reefs, illegal collection
    • - Conservation groups, government influence.
    • - Clearly another black-eye for aquaculture!
  • How do we combat this?
    • - Limitations on collection.
    • - Limit number of fish (Bahamian 50 fish/permited species).
    • - Limit number/size of speices (FL restrictions on 49 spp.)
    • - More reliance on aquaculture (HBOI 2000)
    • - Artificial propigation (“just borrow some”)
culture of ornamental fish
Culture of Ornamental Fish
  • Variety of culture methods
    • - Closed systems (tanks, ponds)
    • - Florida- 0.1 acre sandy loam or coral bedrock (
  • Semi-intesive densities
    • - tiger barb fry (pond) = 10k/m3
    • - clown fish (tanks) = 700-3800/m3
