uncles used to seine crayfish by the bucketful -- back when
five-gallon buckets were made of metal -- not white plastic.
LA and Steve seining for crayfish last millennium.
Your Own? If
you want large quantities of crayfish, use a minnow seine.
The 15-foot long ones will collect scads of these pincered scavengers.
If you need only small quantities, they’re more practical to buy.
They’re an inexpensive pet – initial cost and maintenance.
crayfish fall into the food (for people) and bait categories.
And then there’s the fun category.
fun to watch bait store workers count these out. Ask for a dozen the
next time you're in a bait store. It's cheap entertainment. Our use of them as pets is not sufficient to register on the
Tasty size crayfish. Mixes with fish about 60 days.
they also fall into an educational category.
All third grade teachers in our DSM biotope teach a “Crayfish Unit.”
Most kids have to share their crayfish.
The lucky ones get to take theirs home after the unit ends.
Lucky for the kids. Maybe not
so lucky for the crayfish. But their
chances of survival are not great in the wild either.
Survivors live about
three years. Most get eaten young -- very young.
Some 500 species
of crayfish exist worldwide. About
150 species live here in the U.S. Most
are about the size you find locally. One
crayfish in Tasmania grows as large as an eating-size lobster.
Technically, lobsters are probably saltwater critters.
Crayfish live in freshwater.
Lots of those rock lobsters from
South Africa are really crayfish.

are really crayfish. You can’t
seine these out of our local creeks. You
probably knew that. But you could find them
in a local creek somewhere. The same
easy-to-follow upkeep rules apply.
They are more likely to de-pincer
each other than our smaller local crayfish.
Blue lobster (crayfish). Pretty, but still not a good mixer.
originally from Australia are not as numerous, so they cost a lot more.
They’re just as easy to keep.
If someone tells you these guys will not eat fish ...
Of course blue lobsters (crayfish) eat fish. Get real.
What makes people say they don't eat fish?
Captive-born Yucatan crayfish get bluer as they
Wild caught Yucatan crayfish. Check out his strange pincers.
Younger Yucatans have less of that pincer growth.
Crayfish. Supposedly, these guys do not eat fish. We gave
ours a half-dozen dead goldfish. They ignored them. Yucatans do
pinch people (your photographer, for example) and they hold onto a net as hard as any other
crayfish. Beware mixing any crayfish or lobster with fish.
The parents of the first Yucatan had pincers covered with a net-like filtering material that
limited their fish-catching abilities. Perhaps they adapted to their
Iowa environment? These smaller than average crayfish love to crawl
out of their tank. You cannot keep them in without a lid.
Yucatan Info. We just call them Yucatan crayfish because two
of our German customers captured them and brought them back from
Yucatan. We haven’t
seen these strange crawdads on any price lists and probably won’t.
They are way pricier than our Iowa crawdads. For more info go to Yucatan
Count the legs and you see why crayfish are called

This means they have 10 legs – their two well functioning pincers, plus
the eight legs they use for locomotion, hugging each other, and food gathering.
