No. Been in government salmonid aquaculture/fisheries for over 30 years.

I'll DM you tomorrow.@ReefGeezer did you do hyposalinity? If you did how low? UV? Other medications than copper? How long did you hold on average? What were you losses percentagewise? What did you feed?
I know the LA distributors, I didn't know that there were distrubitors in Tampa. I had the impeccable timing of buying my business on 9/1/2001. Had to drive to LA to get stuff.
Did you ever buy directly from the collectors?
I am trying to get information on the front end of the chain. Did you know or talk to someone at length about the proccess from collector to distributor?
Sorry for the questions. I have nefarious motives.
Just saw the 5k halides for coral ... yuk I do hate that color.
If you want to move this to DM let me know.
Awesome! tyvm.I'll DM you tomorrow.
You missed out using meds on an unknown issue. That's the kind of thing somebody who hasn't a clue what they are doing do and by somebody who has been in the hobby no time at all. I think they say thats only something a nob would do.
WOW! 12 years in the hobby and at least up untill 18 months ago still making nob mistakes. Didn't learn so much in the first 10.1/2 years then throwing meds at an unknown issue buying fish that were so stressed out it died when you stressed it even more. So you couldn't spot a very stressed out tang and still bought it. Another major nob thing to do.You say they said it won't work, but I thought you were providing proof that it does work. Were you saying an idea, or are you talking about actual results?
Not really true. I've been in this hobby for 12+ years now and it looks nothing like it did 12 years ago. If anything, people are way too accepting of snake oil methods.
LOL, that lecture was 6 hours long. The first 3 hours were interesting but the last 3 hours were way over my pay scale and I was praying for a fire alarm test.I guess if I am bored and have the chance to sit through lectures on it like Paul then I can know more. Otherwise this is all an esoteric waste of time. The proof is in the pudding.
HaHa. If I told you how long I have been in the hobby, you won't believe me but the President then was a General who helped us win WW2.I have been in this hobby for 40 years, not much has changed.
The researchers from Oregon was OK, but as soon as researcher's from Cali were added, they lost all credibility.Researchers from Oregon State University in Corvallis and California State University in Fullerton led the most recent foray into unexplored reservoirs of bacteria, concentrating their attention on the protective slime, or mucus, that coats fish.

The team chose to focus on younger fish because they tend to have thicker mucus layers. The extra mucus is necessary because their immune systems are relatively undeveloped, which means that they need additional protection.

As for baby fish coming out with full immunity. They certainly do. They have the same immunity as their Mothers. I did post the scientific study on that before but I have no need to find it now. I think I also put it in my book someplace.
Every retailer kept fish in copper back in the day. I can see where some variation from mean could be caused by differing stages of the parasite's life cycle in individual fish. However, I firmly believe the bigger factor was stress and food.
Personally, I don't believe in true immunity to parasitic dinoflagellates like Velvet. However, I do think that when fish are otherwise healthy, provided the right diet, and remain unstressed they can exhibit immune-like characteristics.
I think it is splitting hairs to argue about the word "immunity" though. It gets in the way of getting good information communicated.
You need a different hobby you have no idea with this one. Not even seen a photo of your tank. Seriously think of stamp collecting or something without animals involvedYou need serious help guy.
Yes I did and they do. The immunity protects them long enough for them to absorb their yolk sack until they start eating. But whatever the Mother is immune to, so are the fry. If they weren't, there would be no fish as bacteria and parasites would kill them almost instantly.Earlier in this thread you were claiming that young fish had fully developed immune systems from their mothers.

Mindme, I have been trying to ignore you as I don't really want to or have to prove everything I say. If you don't believe any of what I post, just don't read it.
If I am a charlatan, so be it, I think there will be quite a few people that may disagree with you, but it doesn't matter as I said, I have nothing to prove.
Have a great day.
One study of immunity in fish fry if anyone is interested.

Abstract
We have tested whether immunity can be transferred from a mother fish to its fry. Rainbow trout mother fish were inoculated against infectious haematopoietic necrosis virus (IHNV) by intraperitoneal injection of a fragment of the IHNV glycoprotein spanning amino acids 31 to 310. This protein fragment was obtained by isolating the specific cDNA from Japanese IHNV strain HV7601 and expressing it in Escherichia coli. Fry from immunized and control fish were exposed to IHNV at various intervals after hatching, and their mortality monitored. Survival of the fry of immunized fish was significantly greater when exposure to virus occurred 7 days after hatching, and some immunity appeared to persist until at least 25 days after hatching.
