Sorting and grading large numbers of Shrimp.

Just wonder how everybody sorts and grades their Shrimp.

I have about 200 Cherries ranging from very little colour to solid red.

Do you catch a few and put them in a glass tank (white Background?) to be able to view them easily, white plastic container??

It's something I've been putting off as the task seemed quite daunting but their numbers keep growing and need to move some on.

Mate I do it two ways, The first is my favourite on these warm barmy nights, I sit in front of my tank with the room lights off I have a small spot light, I shine into the tank any shrimp I see that has not the desired thickness of colour I catch and put in my cull tank. The second method I use is to catch a couple of nets full put them in a white plastic hand basin and take a photo of them with my mobile, very easy to count that way, I then take the basin put it under a strong light and grade them that way. I think the first method is the best because you can see the shrimps side on and you can easily pick out the ones that are more opaque and it is a lot easier to pick the sexes side on, than from above. You can then put the keepers into the basin ,photograph and count.:triumphant:

Don't worry about grading them mate. Just take the best looking ones out and discard the rest. Breed the good looking ones until they breed true. Then you can give them a grade.

Was gonna reply, But the two posts above pretty much summed up everything I was gonna say.

I'd let them breed true by removing the less colourful and letting them develop more strong genetics over time.

Just make sure you don't take all the males out as these are usually the less colourful

Thanks for the feedback guys, will get them sorted this evening. I like the Fire Reds so if it has red legs I'll keep it in my display tank.

Everything else can go in the rack.

Cheers.

      My parents have an aquarium, so I don't know if this will help, but still want to leave a suggestion. They also liked the idea of installing a light strip in it, so they started looking on amazon. I don't know what went wrong, but it broke on the fifth day of use. I think it was a cheap Chinese thing (although the website told me it was waterproof and durable). They asked me for help finding a better option, and I advised them of the smart LED multi-color light strips I used in my car. Being pretty skeptical, my dad still decided to try them. They have been working fine for a month now and don't even flicker. Mom says the fish are happy, lol. I hope my comment was helpful

      It's not looking good. Quarantine any shrimp showing Necrosis, as it can be infectious. Tell us what your water parameters are, and do a heavy water change after that. Increase surface agitation to get more oxygen into the water. A bit of H2O2 (hydrogen peroxide) into the water to increase oxygen might also help the shrimps that have not yet contracted this.

      Sorry to see you have a problem. Try reading the section on 'muscular necrosis' in the below section. You will need to scroll down through it until you see the bold red heading of that description (it is quite a large article covering many problems etc, it is about the 5th item on the first page);   I don't have any personal experience of this but do ask any questions as someone may be able to help. A bit more general info may also  help, your setup, number of shrimps, how long you have had the shrimps, any water parameters you may have etc?

      Hello, I was wondering if anyone here had any first-hand information on these particular pictures. It describes exactly what a few of my shrimp have. The second picture is spot on and most accurate. Thanks

      #4 looks almost like a juvenile female to me, just looking at the abdomen in the top left image, but definitely looks more male in the other two images. The colour suggests it is an adult though, and it’s lacking a clear  so Simon is probably right in thinking it is male, that top left image is just confusing me a bit. If you’re going to get a female, to be sure, make sure it’s got an obvious yellow saddle. That’ll help you know it’s mature as well.
