[Coral-List] Fw: Marine Aquarium Trade

Wed Dec 13 16:12:44 UTC 2023

This is a very good topic to discuss. 
I personally have been in HOBBY since I was 11 or 12 years old. 40 years ago coral were collected on a much more wider spectrum. Maybe about 20-30 years ago the coral collection became more selective, customers wanted more colorful, more unusual colors, a demand that calls for a more rarity in stock. Collectors eventually started focusing on color as they racked up more value. Due to the rarity or unusual colors mainly from the zooxanthellae, many were given a “name” such as once called “purple hornet” and over time this single clone end up being grown into hundreds by hundreds of colonies among aquarists so clearly this clone is well preserved in the hobby say it goes extinct in the wild. 
Biggest negative impact today the hobby has on these “conserved corals” would be their locations of harvest are unknown…….. we can’t simply reintroduce cloned corals from the hobby back into the wild without knowing where they are native (or genetically native to).

I think they mean that if you profit from the live coral aquarium trade, you don't want to lose the resources you make money off of.  However, I would argue that there is a greater incentive to exploit the resource.  This probably fits under the titles "scramble competition" and "the tragedy of the commons."  Namely, whoever gets to it first, gets the best pickings, and if you are late to the picnic there may not be anything much left to eat.  So there is an incentive to exploit the population faster and as much as you can.  Garret Hardin wrote a famous paper in Science long ago entitled "Tragedy of the Commons."  Exploitations of nature can fit into this category, especially fisheries.  In fisheries, it is sometimes called "the race for fish."  The collection of wild corals for the aquarium trade is an invertebrate fishery.  Corals that are farmed are not a fishery, but there are hybrid systems where people are alleged to take corals from the wild, grow them larger in captivity, and then ship them to the US or Europe, the largest and second-largest buyers of living corals for aquaria.  People can grow them completely in nurseries for the trade, but it is probably faster, easier, and cheaper to collect them.  There is pressure on countries to better regulate coral fisheries and to shift to farming corals for the trade.
>       Coral fisheries are a threat to corals, however, they are a relatively small threat compared to the big threats such as climate change, land-based pollution, overfishing (of fish) and disease.  It could have intense effects if there are small, heavily exploited areas, and on rare, slow-growing or reproducing corals that are popular in the trade (such as rare fleshy corals).  All threats add to the total threat to corals, but some threats add much more threat than others.
