  1. Yesterday
  2. The fish don't know if they are Athur or Martha LOL... Just on water testing Bryan...I've found I need to test and log at least daily when cycling, then with the tanks cycled, maybe weekly or even two weekly if results allow...I found I only need to reach for the water test kit when I find an issue then I may test more frequently until the issue is solved then I stretch the timing out again. I look for visible differences also use my nose and ears, then if something doesn't smell or sound right I start to investigate. Cheers.
  3. Last week
  4. Thank you Cecil I will check it that book when I get a chance. And as far as the fish thank you for the advice.
  5. Sorry that you lost a few of the fish. But I know that you will work out the issue for the next go. Keep up the good work.
  6. AquaT, If I was you I would start out with a hardy species that will give you the least trouble for your first experience. That hands down is tilapia. And after you rear your first batch it's easy to produce your next batch yourself. I would strongly suggest a book available on Amazon for about $20.00 called Small Scale Aquaculture by Steven VanGorder. Not sure I would recommend building the RBC he recommends but there is all kinds of other information.
  7. Well, this is strange, "bigdaddy..." To answer your question about water testing, yes manually and we are not testing enough, My school has an Evromential Engineering Technician program and I hope to get them more involved with my water quality testing. It would also be great for my students to learning about data acquisition as well. The sticker work is funny and practical. We thought we had better get a bottom-dwelling fish species to clean up any sunken food and our students provided some bullheads (like a small catfish) and they just dumped them in the tank. We then thought we should have measured them to track their growth as well, but, it was before we had a net. The student said "no problem" went out grabbed his fishing pole and caught them right back out of the tank. haha
  8. First harvest and updated pictures.
  9. Regular table salt is fine. No need to go to the extra expense of buying sea salt. Allegedly you want the NON-ionized salt but I'm skeptical if it really makes a difference. And I am not alone.
  10. Thanks. I did lose up to about 15 or 20 from bacterial issues and subsequent fungal issues from the move. As I indicated moving fish is stressful and brook trout are right up there with crappies as far as sensitivity to handling. Part of the problem was females that were egg bound, which added to the stress. If female trout don't have optimum spawning conditions they will hold their eggs and attempt to reabsorb them which is stressful. When I move 100 male brooks, about 60 tigers, and 60 browns back to the trout pond in late spring I will be lacing their feed with a broad spectrum antibiotic to curb any more losses. Most likely the losses will be less, as I will be able to feed them well vs. the dropping water temps and lower feeding activity which I ran into this fall. Whenever you handle fish, being able to get them back on feed ASAP is important. So rising water temps helps that. And even with trout, dropping water temps below optimum means heir immune systems aren't working 100 percent.
  11. Very impressive Cecil. I love it!
  12. Sea salt or basic table salt?
  13. Hi AT, My direct answer is not going to be helpful to you, but I'll try to expand. I've moved into a brand new house so ATM I don't have one running. When time permits I will though. These systems last as long as you want them to. If you are using gravel or clay or other course media, the media does eventually clog and you need to replace it. If you have no other filtration they do no not last as long as if you were to properly filter with MBBR, swirls or other filters. There is plenty of info on this forum about that if you use the search function. If you decide to do iAVs the correct sand is the key, no other filtration is required and it is not known how long the sand will last at this stage but all reports are substantially longer. If you want to see what I have done over the years use the search function and you may need to dig a little further into the archives. Lots of people have also posted their systems in the build section plus, we would like you to post your build as you go along your journey as well, this helps other future newbies and also helps the current community. Cheers.
  14. Thank you DB, I will definitely keep that in mind. How long now has your system been in operation?
  15. Great insight, thank you Cecil!
  16. Yes salt reduces stress, and handling or transporting fish stresses fish. Even rearing fish in tanks is a form of stress. Salt is known as the "aspirin of aquaculture." Simplified when freshwater fish are stressed they give off salt and have a hard time staying in a "salt equilibrium." Adding salt to the water helps them stay in equilibrium. About 0.5 mg/l aka 5000 ppm, aka 5 ppt is usually the recommended rate. I use 0.2 to 0.5 mg/l in my aquaculture tanks indefinitely. (Not aquaponics). http://darc.cms.udel.edu/AquaPrimer/saltusencrac105.pdf
  17. Mistake: Not being patient when doing first cycle and wanting to change the water because I thought the water readings were too high. Remedy: Posted everydays reading on the forum and told people what I wanted to do then listened to their advise, became patient and did not change the water. Cheers
  18. Thank you Cecil, my plan is to raise live food for all of the fish. And use Salt in the water for transporting?
  19. So, when you all got started with your first systems what were some of the rookie mistake that you all made that can be easily avoided? Thank you in advance
  20. I have both in tanks and have no issues. That said, black crappie usually aren't sold feed trained. If they are not feed trained good luck getting them to feed on artificial feed. And they are very sensitive to handling. You may lose a good amount initially. Make sure you use salt when transporting (0.5 %).
  21. Awesome looking forward to seeing some pictures.
  22. Hello everyone I am new to the Aquaponic scene but not to the concept. There is a lot that I still have to learn but I am ready to get rolling and producing healthy fish and produce. I look forward to all of the wisdom shared from you all.
  23. Good Evening, I am new to the forum, and also new to aquaponics. I am in the planning phase of my first 50 plant Aquaponic tower system an was considering doing both Black Crappie and Yellow perch in the same tank. Is this wise or should I just stick with one fish for now? Thank you in advance for your wise advice.
  24. Earlier
  25. You're welcome. You appear to be doing your homework which is good. I think you're going to find there have been a lot of failures attempting to do what you want to do.
  26. Thanks for the info!
