Anyone interested in biology?

Here's a link to ongoing studies of ich and the development of immunity ... kinda academic, but very interesting to see the connections between the parasite and development of immunity in fish.

One possible cause of an ick outbreak in coldwater fishes (like hillstreams) is found here:

http://www.lsc.usgs.gov/fhb/workshops/27/15.htm

"Our three cool water facilities, which respectively rear muskellunge, tiger muskellunge, and walleye, are generally unaffected by the parasite. Seasonal water temperature conditions that favor development of Ich at the cold-water facilities are believed to be the primary factor. The use of surface waters subject to mid-summer temperature spikes, at least in part, seems to precipitate predictable epizootics. "

In other words, changing temp from cool to warmer can be a catalyst for ich development in cold water fish.

Do you know at what temps the infected hillstreams you saw were being kept?

And an interesting development in current ich research in China with a homeopathic 'recipe' for treatment...

"Based on variation of surface immobilization antigens, four different serotypes of I. multifiliis were found in eight parasite strains isolated from cultured eels. Our findings suggest that differences in serotype correlate to variations in temperature tolerance. A recipe containing ginger, capsicum, pepper and borneol has been used effectively to treat Ichthyophthirius-infected eels in densely stocked concrete ponds."

And yes, there is such a thing as ich immune fish...

I LOVE this kind of stuff! Facinating, ain't it?

One more and I'll quit...promise.

Link to abstract of article published jointly by the China ich research team and Dr. Clark from Cornell. Vaccines may be on the way...

Cool, eh?

OK, this is the last one...really!

Summary of how the immunity experiments are working and their rather conclusive results thus far:

Martin.

Positive, I've seen an ich dot on my SpB at the store, and I've seen much more serious ich which wiped out the remaining gastros in the same place about a month ago.

I suspect that any fish can get ich if its immune system is down (after shipment).

BTW, there may be another belief that is false: salt and hillstreams. I've been trying to collect at least some info on Vantanmenia and it turns out that at least one species (and some other hillstream sp.) is described as brackish?!

It is ready, we are only waiting for an OK. Maybe someone has a better way of contacting the site owner for it? -- I'd not mind carrying a few along since I'm checking stores for hillstreams now. Or maybe we can just go ahead with it?

Mike,
Did you email Jeff? If not, I can ...and will attach the pdf.

Did, more than a week ago, no reply. If you could do it too, it would be great.

Jeff said it looks great and to go for it.

"Looks great Shari! Sure, go ahead and distribute it.

Thanks,

Jeff"

Get rid of the watermark and we can print and distribute as we like...please post the link to the final copy.

Good job, Mike.

Wow! You surely get things done.

The final flier has been waiting for you in the same directory:

Let me know if an A4 version is needed.

Ready for the next flier? (I had fun with this one, so why not a couple more like this)

---------

PS. Ah, I see what I did wrong: I emailed to comments@aquaweb.pair.com, he probably does not check it.

Ignorant here...what's an 'A4'?

European paper has different dimensions, this is their main format (not the same as the "letter" in the US).

duh!

Guess you can tell I've never done any written work in Europe, eh? Did alot in Israel, where they use a completely random selection of paper sizes! Very aggravating when trying to keep files in a consistent manner.

Isn't A4 8.5 x 11"?

Anyhow, stop with the Ich stuff already....I'm coming out in spots

Martin.

I bought some hillstreams (either H. yunnanensis or more likely Sinohomaloptera (now balitora) kwangsiensis)
a few years ago and discovered they had ich after getting them home and into the Qtank. I treated them successfully with NoxIch at reduced strength and they recovered with no problem. Other than that, I have only heard of hillstreams getting ich one other time. In that instance, they were in a store and the treatment applied at full strength killed them.

According to Wikipedia:
A4 is a standard paper size, defined by the international standard ISO 216 as 210×297 mm (roughly 8.27×11.69 in). It is the normal size of paper for both domestic and business purposes in all countries except the United States, Canada, Mexico, the Philippines and Chile. See paper size standards in North America.

An A4 sheet cut in half along the long side produces an A5 sheet. An A3 sheet is double the size of an A4. All the A paper sizes are similar to each other. The ratio between the long side and short side is the square root of 2.

Martin, haven't you ever been out of North America?
