Pepermint shrimp breeding

[Mashaw]

Hi just wondering if I could ask afew questions about breeding, Iv a
Had a look through some of the threads on here but am not really seeing any answers to my questions

what is the general survival rate for settlement? Iv heard less then 1%?

And iv read that peps are still not able to be bread on a large scale due to the massive fry deaths, is this true? Or have things changed?

Thanks

Never tried it myself, but there is a little book out about keeping and breeding them: How to Raise & Train Your Peppermint Shrimp

not so much a matter of times changing, it's the tools available that weren't available before. the space, time, money and labour are still there to deal with.

Larvae is pelagic thats why the survival rate is verry low in a normal aquarium but in a kreisel aquarium things change a lot .

A Kreisel Larvae tank is the key to success, not just with shrimp, but also with fish.
I had a real breakthrough when I switched my fish larvae tanks to a kreisel form.
Which kreisel form is best depends on the species.

I linked a pretty good article in this thread: Tank designs for the larval culture of marine fish

The Modified planktonkreisel tank design is probably the best for shrimp.

Ok cool well I was just wondering as I did a lot of research into the breeding of peps and I was seeing the same common mistakes and or problems that people were having so I worked back wards and built my own system,
It is running arm and I have fry in them but my first batch was only a small one, about 40 or so and Iv only lost about 5 fry and I'm at day 10.

I guess because it's a very new system and unlike anything Iv seen befor I'm just trying to get an idea of percentage losses by about day 10' I'm not so much trying to breed the shrimp it's more of a test for the system itself as its only a 2 tank system I just want to see if my efforts in building a new style of system was worth it and is worth it befor I go building a big 8-12 bay system

Most info I could find was from posts on forums that were from 5-10 years ago, so if anyone could give me a rough time percentage survival rate to settlement now that would be great as I can not find anything

 

[Mashaw]

The new system Iv set up has been taken from a number of different breeding styles of system and build into one.

I think Iv managed to combat these problems

1. Cut down daily maintains to about 10mins per day totally on the whole system, which inc feeding, cleaning, water changes and setting up feeds for the next day

2. Sorted out the death by bad water issue

3. From what I have read, reduced percentage of losses upto day 10 by a fair bit

And a number of other things

With shrimp larva you want also make sure to watch iodine levels and replenish them if needed.

 

[Mashaw]

Yeah cool, thanks for the advice

 

[Mashaw]

Needing some help, Iv set up this new style of system and its working very well, with minimal death, but as soon as I get to around the day 9-10 mark my death rate goes through the roof, can any one shed some light on this?

 

[Mashaw]

Why is it at this stage things seem to go bad? And not just for me, Iv noticed a lot of people have a lot of death around this time? Tia

 

[tri4god]

I would love to give this a shot.

It could be a molding issue between larva stages. Are you making sure the Iodine level is high enough? That is usually one of the problems you run into with shrimp.

 

[Mashaw]

No, totally forgot about that, do they really suck it up? The fry system gets a water change twice a week

 

[ThRoewer]

I'm not sure how they take it up, just that iodine is important for molding.

Hmm thanks much for the info, I seem to be getting really good results up to the mark, next to no deaths, then on the one night just about everyone of them die.

Can you suggest any other foods I might be able to give them other them Rotifers and green water and BBS?

 

[ThRoewer]

The defined point in time where they all die points to a molding issue of some kind.

As far as I know, shrimp and shrimp larva hunt more by using tactile and chemical than optical senses. So as long as a food "tastes" right and is in reach they should go for it. I would give micro pellets or finely crushed flake food a shot. You could also try small sized frozen food.
The only thing to watch with these feeds is the water quality.

You can raise the peppermints in a standard 10 gallon tank, with just a heater and air bubbles in the corner. Feed them baby brine shrimp and siphon out any detritus that builds up. After a couple weeks, you can even feed them frozen foods, and they'll pick it up off the bottom and carry it around with them. I've never had iodine issues, as it's already in our salt mix. Highly unlikely your water is deficient in it.
Biggest problems you'll encounter is with the late stage larvae breaking off arms. Bubbles are like wrecking balls to those guys. If an arm breaks off, it takes 3 molts to grow back, which is 12 days or so. They will only settle if they have all their arms, so it can be frustrating when you check and find your biggest larvae missing a leg. lol

This is very helpful as I didn't know there used more of a tactical style rather then optical, I will take your advice and maybe try and add a little flake and see if that makes a difference

As far as water quality goes, this is not somthing that I really need to pay to much attention to as the system Iv designed has a sump that it runs on with a very large water volume and has twice a week water changes.

I did take this into consideration when I started to encounter these issues but it came down to the face that I have the same deaths at the same time from all my batches and also all of my breeding shrimp are in tanks on the same system and they are not showing any issues
