Do you need to get a new "blood" of shrimp for breeding?


I've been reading some forums that said you need to get a
new "blood" every now and then for shrimp breeding? If I don't
they get deformed? So to solve this, can I just go to my LFS and
buy like 1-3 new shrimp, or do I have to buy it from a different
store?

Its hard to tell if the LFS keeps getting the same inbred ones or not.

Every 6 months would work IMO

To my knowledge there's not been a confirmed "deformed shrimp" yet that is linked with inbreeding. That is much more common with mammals. In theory because mammals are built genetically differently to spread out and travel into a much wider range of area, while shrimp are built genetically to be able to accept inbreeding much better since often they may be confined to a much smaller area and have to breed with each other to sustain a population.

This is a post from a different thread:

Shrimp can inbreed for years without any problems. To start a new strain selectively breeding AND inbreeding is necessary. Deformities are not really an issue with shrimp, although I admit that inbreeding depression (lowered fertility) may develop after several years if not introducing new blood.


Here's a quote from the scientific paper from GENETIC DIVERSITY STATUS OF WHITE SHRIMP Litopenaeus vannamei BROODSTOCKS IN MEXICO by Ricardo Perez-Enriquez, Fidencio Hernandez-Martinez, Pedro Cruz*, Manuel Grijalva-Chon, Josefina Ramos-Paredes, Fernando Mendoza-Cano

Centro de Investigaciones Bioldel Noroeste, S.C. (CIBNOR)
Mar Bermejo 195, Col. Playa Palo Santa Rita, La Paz, Baja California Sur, Mexico 23090

"Management practices for almost 10 generations since the introduction of a single stock from Venezuela to Mexico, had permitted the broodstocks to retain high levels of genetic diversity. "

A decrease in the number of alleles were also not found.

This doesn't mean years later they wouldn't have inbred depression, but it is nice to know that the hobbiest has several years before possibly encountering anything.

That's good to know since, I only
know two LFS that sell shrimp LOL.
After u thought about it for awhile,
is that really even nessacary because
how did we get from a clear wild shrimp
to a full red shrimp? Obviously interbreeding,
and how do I know my LFS hasn't been
doing that themselves.....

I would recommend ordering online from reputable sources, not your lfs. More diversity and typically better prices.

I would go even further and say buy from members of this forum. The people who sell here do so because they love shrimp and almost all take excellent care of them. They know their own stock better than a fish store who is just a middleman. And the goal of shrimp hobbiests here is to breed the best stock they can.

Buy from someone you trust, and that is worth peace mind every time!
