So far...it’s been all about the food!


  • Aquaculture has been (and may always be) about feeding people.


“But Dr. K....

What else is there??”


Ornamentals

“Feel good” fish!


  • First...lets revisit food fish aquaculture.


(Tlusty 2005)


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.


Making fish makes money!

Source: 1998 Census of Aquaculture, USDA-NASS


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 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

  • 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
