Some folks wanted to know where to buy fogging nozzles.   A few years ago, I
raised some hogs in confinement and I used overhead "fogging nozzles" to
keep them cool.   I believe these are also used in poultry operations.   So
possibly large farm supply stores might have them.   But I just put "fogging
nozzles" - WITH those quote marks, in the world's best search engine
www.google.com and you immediately see a whole bunch of suppliers!  We all
have the internet!  Make USE of it!  It's a wonderful tool.

I first tried "fogging nozzles" in the world's best search engine and got
141 sites, then I tried "Fogger Nozzles" again WITH those quote marks, and
got MORE sites, then I tried "atomizing nozzles" and I got over double the
sites, I believe it was 323 hits!   Search using www.google.com   Hope this
helps.

I was thinking of setting up the system as follows Polytanks with 5-7 females to a male, with flower pot saucer on the bottoms for nest. (UNclear area) I flow from these tanks into a yet to be defined lower "fry catchment tank" (???), and out to a solids seperator of sorts and then to the biofilter and then to the growbeds. The water would then be recirculated into the brood tanks after passing through a UV filter. What is unclear is, I could also opt to just grow the fish in the hapa method in the 5-6 foot wide polytanks, but I am afraid that too much poop would accumulate in the nets. After 5-7 day I would need to have an excess tank(s) free to now move the broodparents into.I could then selectively remove fry from the hapa into my smaller containers. You see if I go one way, it means knowing how to drain the solids from the tank without making scrambled fry and getting fry and poop seperated, :> and the other means added expense making up a lot of nets and hapas. I would like to go a middle route between "old school" and new way!!? Am I making much ado about nothing . anyone? Thanks guys. Good to know you made it back safely Arlos! We'd like to see pictures!!

When I am close to the tanks they beg me for food but this does not happen if say you or any one other approaches the tank they will ignore you for the most part. Because they are only fed by me .Also If you watch a holding female she defends an area around herself to keep it safe for the release of her young and she will not release the young in a dangerous place so you can say that these fish have a sort of intellect . So If you build your tank with a sort of shelf less than say 5inches deep on one end at the tank top with the shelf too shallow for an adult to get in to it and hang yarn mops in it thickly from say a PVC frame.And you make this shelfs entrance either with a weir or so you can close it at will with say a sheet of glass. And the tank absolutely has no other cover for concealment then the young will all be released at this area and they will not leave its cover for any reason to swim with the sharks.So if you place a drain with a stand pipe in this shallow end shelf (independent from the main system drain and stand pipe in the deep end) and once a week or so you close the weir and pull out the stand pipe you can see how all the young fry will be sucked out and sized for stocking wright. This way you don't have to strip the eggs or fry from the females but thats easy to do too. Some folks are just afraid that they might hurt their breeders .I will explain that if you like Bruce | Message 14 Subject: Re: SEC: UNCLASSIFIED:-Re: Pond Aerator Solutions From: "Judith M.

Abalone require fresh macrocystis pyrifera (giant brown kelp) which must be harvested about once a week. abalone feeds are being developed but as of yet fresh harvested is best.I have 100 of then about 2 1/2 years old. After 4 years old, the growth slows as they spend energy thickening their shells. I raising them only for water quality data ( not to mention one heck of an AB feed in about one year) Abalone can be raised in a closed loop system but they are a species that are indicators of changes in the environment. Easily stressed. water must be maintained from about 45 -58 F After 65 F they are susceptible to withering foot syndrome. The best place to aquire them for a commercial supplier is the AB Farm Inc. in Cayucos, CA. Contact Brad Buckley at 805 995-2495. tTheir site is www.abalonefarm.com or email brad at bradab 'at' aol.com. Great people. They will ship live to you.Very good facility. If you want to set up an operation, I can help with that. Runcorrectly they are a great long term investment like a winery, not a bad lifestyle either. I asked Brad how he came to end up on the end of a cattle trail, overlooking the Pacific, directly in the middle of nowhere. he said he started by cutting pipe. He had mentioned this after saying he received his degree in Public relations at which time I piped up with, " This must must have been a proud day for your parents". He's done alright now as sales manager. After spending years building water treatment systems for the silicon valley's electronic industry I'll take Green Acres any day.

This is EXACTLY what I suspected I am interested in building a smart tank so you hit the nail on the head. Apparently those who strip their mama fish's mouths, for fry get an even higher yield.
