Respectfully, Wayne, SeaScope is a hobbyist publication, and it's put out by Aquarium Systems now known as Marineland - the aquarium salt manufacturer.
Mary, I get Pet Business, and I've picked up a copy of Pet Product News and I think I get Pet Edge but it's mostly dog/cat stuff, so I don't bother reading it. I get some entertainment out of Pet Business, but honestly I just kind of skim through it. That reminds me I have an issue lying around here somewhere, perhaps I'll take it home and read it
When I go to trade shows I come home laden with all manner of literature, I try to read the more interesting stuff.
On a hobbyist level, the new Daniel Knopp publication, Coral, seems to be very high-end, very specialized and in-depth. It's selling very well, it's not one big ad, it's retailer-friendly (no ads for every mail-order house on the planet) and the articles are just that - articles, not masked advertisements.
