Hey all, i need some help with a problem that i have. i'm going to remove 170 silver perch from my 5000l tank and i'm looking for any suggestions on the best way to do it. I want keep the water in there as i i'm replacing them with trout. And also is it okay to use Flossy (butcher's) salt to treat my water? |

If you going to move that many perch to another tank... then lowering the tank level and anaesthetising them is the recommended way... I got lazy the other day and chased mine around the tank for a couple of minutes... Result today... dead fish... as Kuda rightly points out... viewtopic.php?f=18&t=3142&p=192761#p192761 |

Not sure whats actually in the salt and it doesnt say on the bag, i'm a Butcher and we use it to cure meat so i think it would just be salt. The perch are only about 40 to 50 mm in size so i was thinking about draging the tank with shade cloth some how, i'm not really sure. |

What do you use to anaesthetise them? |

Wills you want to make sure. Curing salt AFAIK has much more than NaCl in it, however I think they were other chlorides like potassium and such. Which if that's all they are, should be safe. But if it has other preservatives I'd be really concerned, so find out. |

https://www.pureandgreenorganics.com.au/ingredients.html wrote: Bubble and Flossy salts are harvested from naturally occurring salt lakes at Koolyanobbing, 450km from Perth, and Esperance, some 700km south east of Freemantle in Western Australia. This Australian lake salt is simply washed and kiln dried - it has not been refined and has no chemical additives. Because it remains in its natural state, Bubble and Flossy Lake Salts have been awarded a Biological Farmers Association of Australia (BFA) registration. This is important when you come to realise that sodium chloride can have chemicals added to it, and very frequently does, without the name changing.
Salts traditionally used in bath salts include dendritic salt and Epsom salt. However, both these salts are actually "manufactured". Dendritic salt has an acid added to the sodium chloride to encourage the crystals to form star shapes and Epsom salt, once mined as a naturally occurring material, is now created in the laboratory as a chemical by-product. Our completely natural BFA registered lake salts are mineral rich, antibacterial and soothing. |

Then it might be easier for you to just drain the tank down and then use a shade cloth partition to gently herd them into an area where you can net them and transfer them with minimal hassle and stress to the fish.. |

Agreed, drop the water to a level that is shallower than the depth of your net, and you'll catch them easy, but don't expect them to come to the surface for food for a while after you do that, they become quite shy. |

Just a question. How do fish like strong light. If you put a couple of buckets on the bottom would the fish go into them. Thats how I move fish. Let them swim into a bucket and then lift it out. |

| Post subject: | Re: removing fish |
interesting idea... is the bucket upright or on its side? have you drained most of the water at this point? Just how patient must you be? |

| Post subject: | Re: removing fish |
On its side and I don't drop the water. A little patient. |

Wills where are you in the WB, ex Morawa boy me, but if perch are that size I have a fish trap I bought in Bunbury tackle shop, you can get them on Ebay as well, put bait in and fish swim in, much the same as a yabbie trap, don't feed fish and just bait the trap, we used this method for catching Pygmy Perch, the best bait.......don't laugh...........Cheese |
