Was not sure where to put this. It relates to commercial operations but it is also useful information...
Anyways, I visited one of the largest live fish wholesalers last week in NSW and did a small write up on my site about it.
For those interested check the link below.
I think in light of people considering niche type of markets, there may be scope to supply through these types of operators.
It would be interesting to hear from other members around the world if they have had experience with these types of wholesalers.
