Mysids & Copepods

[scyphozoa]

I know mysid shrimp will eat baby brine but do they also eat copepods? (If so, can one make a refugium so that it is shrimp proof?)

 

[GreshamH]

Yup, they sure will. They'll eat their own young, if given the chance.

 

[scyphozoa]

Not that it is a problem but I have Mysis everywhere--my sump, my overflow, and in the main tank. How could I construct a refugium to boost copepods that would be shrimp safe (...a refugium for the refugium)? Also, would this be of little use since once the copepods entered the main tank they would more likely be food for the Mysis and not my fish or other inhabitants?

Place a 50-100 micron filter sock or screen between the water source and the refugium itself. This should prevent any mysids (including the juveniles) from getting into the refugium and allow the copepods to be fruitful and multiply.

Ahhh..."they will eat their own young" comment.....mysid larvae cannot survive without their mothers.....they may eat them, but they also nurse the larvae .....go do some research and you will see that this is a loaded statement he made

"they will eat their own young" is a completely true statement ... I am in the process of setting up a Mysid culture and you have to rig up different size screens that overflow into other tanks so the juveniles can escape the young. Not sure if the mother actually nurses the larvae because they are susceptible to cannibalism at day 1. I don't see how his statement was loaded???

are mysid shrimp in most of our reef tanks? is this rare? do they come in on live rock?

Mysids are very common and are hitchhikers on anything from live rock to coral.

Are we talking about Gammarus Shrimp or Mysis shrimp here?

Yes do research it, you'll find what I say isn't loaded :lol:

Young doesn't have to equate to larvea I happen to work fairly closely with a bio essay lab that grows mysids mainly for EPA bio essays, the rest are sold thru the company I work for. I've looked into mysid culturing very extensively, as have a few of our staff PHD's, as it was something we considerred growing at one point. After seeing how it's done, we decided that is was more profitable, and far easier, for us just to buy them. Screening every stage multiple times daily is a lot of work, when you talking about the size we'd have to do it at.

We're talking about true marine mysids
