Managing the Aquarium Trade

History

Global Economic Impacts

  • Export
    • Dominant in developing tropical countries [1]
    • Poorer countries are often centralized around the trade as a means of income [1]
  • Import
    • Dominant in developed countries with expendable income [1]
  • Overall global impact
    • Involving 350 million fish annually [2]
    • Industry valued at $963 million [2]

Aquarium Trade as an Invasion Pathway

  • Major source of exotic species invasion
    • In part caused by owners that feel they don't wan't
      • Re-released into non-native waters
      • Sometimes affects ecosystem balance by out-competing or throwing off natural food webs
  • Often goes unnoticed
    • Hard to regulate
    • Focus on other invasion pathways such as ballast water

Case Study: Hawaiian Islands

  • first significant study on the effect of aquarium collecting on natural populations [2]
  • Large study on Kona, Hawaii
    • 7 of 10 species surveyed were significantly affected by collecting [2]
    • Abundance of many fish is lowered [2]
      • affect on those surveyed ranged from 38% to 75% lower in abundance [2]
    • Few Non-target fish were affected
      • only 2 effected [2]
      • not indicative of over fishing pracitces [2]

Prevention Methods and Future Impacts

  • Reef Check Program <ref name="check">Hodgson, G. "A Global Assessment of Human E€ects on Coral Reefs." Marine Pollution Bulletin. 38.5 (1993): 345-355. Print.Cite error: The opening <ref> tag is malformed or has a bad name
    • checking indicator organisms
    • around 300 reefs in 31 countries
  • Re-release regulation
    • Hard to enforce
  • Regulation on collection
    • also hard to enforce in developing countries

References in Popular Culture

  • Finding Nemo
    • Sparked interest over the relatively unheard of industry.
    • People now want "Nemo" or "Dory" fish
  • The Spongebob Squarepants Movie
