  1. If they are growing and eating well I wouldn't be too concerned, but keep an eye on them. What are your water parameters like, ammonia, nitrites, PH? Anything that could be stressing them? Remember many pathogens can be there but not effect the fish until they are stressed. Sometimes you just have a few fish that have issues while the rest are fine.
  2. 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.
  3. 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.
  4. 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.
  5. 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
  6. 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 %).
  7. 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.
  8. I would join the following list serve and ask. Joining the Ohio Aquaculture Association wouldn't be a bad idea either. Ohio has done a lot of things with yellow perch and there are a fair number of growers over there. I've seen some good articles on just what you're asking in their newsletters. I know there is at least one buyer on the list serve below. Don't be thrown off by it being Ohio. Lots of people from other states on there including me. Aqua-ohio@lists.service.ohio-state.edu Last I knew Dr. Laura Tiu was the administrator. A guy that really knows his stuff on yellow perch is Bill Lynch who was president of the Ohio Yellow Perch Association last I knew. Even though he rears yellow perch he's not reluctant to give advice and give out his knowledge. He used to be an extension agent for Ohio State.
  9. Ande, Neither one of those hatcheries is for food consumption with one being state hatcheries that supply fish for stocking public waters and other for stocking recreational ponds.
  10. Just keep in mind the largest yellow perch farm in the world couldn't compete with wild caught perch and after pumping more than 20 million dollars into the operation and switching over to rainbow trout. All that money and still couldn't do it. Sold and under new ownership, and last I heard they will be raising genetically enhanced salmon.
  11. Hey Andy,

    Here's a cast of one of your European perch (Perch fluviatilis) that I assembled and painted as an American yellow perch (Perca  flavescens).

    18 inches (45.72 cm). 



    1. ande


      Nice,  :bow:

       Where I fish them 8-10 inches is big, 12-14 huge and 18 unheard of

      Must be too cold up your way? I've heard of some really big ones in Russian and Eastern Europe. 


  12. I had another heron on the big pond yesterday evening. Had a small trout or yellow perch in his mouth. Since I have two federal permits and one state permit to take herons out I got the shot gun out. Don't know why but he flew off apparently unscathed. I should have hit him. It was raining pellets all around and behind him. Proabably went through the feathers as there is not much to these birds but feathers and skin and bones. Should have been closer but it's hard to get very close to these birds. If I put the fear of Cecil into the bird and it won't come back that is fine with me. I'd prefer not to kill them.
  13. Hey Andy if he was raising Arctic char like you have up your way it might not be so bad.
  14. I've moved 108 male brook trout, 218 female brook trout, 71 brown trout, and 70 tiger trout to the biggest pond on the property. Total of 467 trout. Only a handful left in the original trout pond that come up for feed. Will probably get them out via hook and line. The following are the only pictures I have as one day a friend helped and he had a cell phone. The next day I was on my own and nothing to take a photo with. Brown Trout Another Tiger Trout
  15. Only day with no rain is tomorrow. But I have a family commitment tomorrow.
  16. For optimum weather I may move it to the weekend. If that is the case I will have access to the wife's iPhone for pictures.
  17. Wish me luck next week. I'm going to stress over $30,000 worth of trout. I'm going to seine the trout pond and place 60 of each species (180 total) into a 12 foot Intex pool until the pond is completely seined out (same day) and put the 180 back into the trout pond with the rest of the fish going to a much bigger pond on the property. I don't want to move them but the pond won't be able to handle what's in the trout pond once they get much bigger. The trout pond carrying capacity is 720 lbs. upon harvest which is ~ 180 trout @ an average of 4.5 pounds minus a 10 percent mortality. This is calculated at 16 lbs. per gpm flow @ 45 gpm. The hope is the trout in the big pond will average 18 inches and approximately 3 lbs. by late May before the water gets too warm, which is large enough to sell although I get a higher price for the trout that will stay in the trout pond until the following fall. Just don't have room for them all and the big pond gets too warm after May. Not only will the Intex pool water be very cool 40's to low 50's F. ( 8 to 12 C.) but it will be have salt solution of 0.5 percent NaCl and ammonia remover. I plan adding a little bit of Tricaine methanfulfanate (Finquel or MS222) to calm them a little. Will also create a circular flow with a sump pump and an agitator to add oxygen. The fish will be moved about 500 feet to the big pond via a trailer mounted 300 gallon tank with a fresh flow agitator. I sold it to a friend but he is letting are borrow it as long as I need it. Hope to this all done in a day.
  18. Could you elaborate on placing the swimming pool on top of the fish tank? I assume it was empty and turned over? I'm having a hard time picturing this.
  19. I use a product called Finquel aka MS-222 (Tricaine methanesulfonate). Have tried clove oil. Don't care for it for various reasons. Used clove oil with water in a container and had a hard time getting rid of the smell of the clove oil! And it's not much cheaper, and the Finquel seems to go farther. Note: Since my fish are not eaten the use of the above is not an issue.
  20. A pic of a tiger and brook trout male quickly caught out of the pond today, anesthetized, photographed, and released. I think you can agree the astaxathin in the feed is doing a good job of coloring them up. Still too warm to move them to a bigger pond. May finally change later next week.
  21. Ande, My problem is I don't have a functional camera right now. I usually use my wife's iPhone but she's not home during the day. I hope to inherit hers soon if she upgrades!
  22. I have 71 four to six in black crappies that are feed trained and are now in a floating cage. I brought them in last fall into a basement RAS that were produced in a small 1/10th acre pond. The pond was planted with brood fish that were caught via hook and line from a nearby lake. Would have had many more but make the mistake of planting fathead minnows (Pimphales promelas) in the pond, and they became so prolific there is no doubt they were competition to the fry and may have even eaten some. Live and learn.
  23. Crappies were released free swimming into the pond a couple of weeks after going into the cage about the middle of June. Hadn't seen any trace of them until yesterday when I seined most of them out. They are now back into one of the RAS tanks for the winter with similar size bluegills and some tilapia. The hope is to get them back on pellets. They don't appear to have grown much if any over the summer but look otherwise healthy. My thinking is since they were hatched from wild stock it may take a few generations of selective breeding to get a better growth rate. At least I was able to get 75 of them feed trained is supposed to be difficult. Next spring I am going to attempt and cross white and black crappies. Black crappies are easily acquired locally and there is a reservoir not too far away where they are all whites. As a fish taxidermist the largest crappies I mount for customers are natural hybrids of the two.
