OK, I finally had a chance to go through the article Todd posted.
Here is the quote from the article about Sri Lanka:
<blockquote><font size="1" face="Verdana, Helvetica, sans-serif">quote
The number of jobs was estimated at less than 500, many of which were probably only occasional.
Everyone should keep in mind that Sri Lanka is an EXTREMELY MINOR EXPORTING COUNTRY. There are not 100's of boxes of Sri Lankan animals entering this country every week, as there are Philippines and Indonesian. I could pick some tiny island somewhere that had one small collection station on it and say "The aquarium industry is only providing 10 jobs". But as with everything, it must be put into context. Sri Lanka is not a major exporting country. Same argument can be made for Puerto Rico and the Maldives.
It says that Hawaii has about 70
FULL TIME jobs. What is the definition of full time? 40 hours per week 52 weeks out of a year? Very few collectors work these hours. Many of the operators in Hawaii are small (hence the article stating there are over 220 collection permits, but 70 full time jobs). Most of these collectors collect and ship maybe 2-3 days per week. Probably less than that during the slow months of summer.
Now to what the article says about the two main exporters of fish- Philippines and Indonesia.
<blockquote><font size="1" face="Verdana, Helvetica, sans-serif">quote
It seems to have stagnated in the meantime due to the negative effects of cyanide fishing (Hingco & Rivera, 1991). More than 2,500 people were thought to participate in this activity
Now, this means there are over 2,500
divers that are participating in cyanide fishing. That doesn't include the ones that aren't, the middlemen, and the employees of the export facility. Goodness only knows how many people are employed
regularly, not necessarily "full time", by the aquarium industry. Again, I'd really like to know the definition of "full time" from the author before I jump to any conclusions.
