    my crayfish farm
    Today I’ll take you on at tour ‘round my noble-crayfish farm
    12 ponds 50 sqm each - EPDM rubber lining
    bottom built as terraces
    deepest step one and a half meter
    middle step one meter and 30 centimeter by the edge
    gravel and stone on the bottom
    at the edge the lining is fixed with stones or boards
    Purpose of my crayfish farm...
    ...is to get more crayfish than I can from my lake
    My model is inspired from the German crayfish farm, Krebszucht-jeske
    Krebszucht-jeske’s model
    Jeske starts stocking a pond with 0-year juveniles from his own hatchery
    ...or have females and males mate in a pond in autumn
    ...or berried females in spring
    young crayfish are fed with sprouted grain or peas or plants
    at 3-year stage they are sorted in females and males
    females for starting new crayfish lakes
    males are put in a grow-out pond and feed crayfish pellets one sumer
    late summer they have reached eating-size 50-80 gram
    and are sold alive for people to have their own crayfish party
    the pond is emptied, mud removed, and starts up again as new
    mud has to be removed in order to get clean water and healthy crayfish
    Jeske’s produces 20 kilo crayfish per 1000 sqr meter
    actually much more in his grow-out ponds
    but he also needs ponds for stock, and for the young crayfish
    to compare - in a good crayfish lake you can fish 5 kilo crayfish per 1000 sqm
    My model is about similar
    but I keep all stages, from 0-year to 3-years in the same pond
    and I don’t feed them
    feeding turned the water into algae soup
    crayfish became covered with hair algae - and got sick
    so I stopped feeding
    but then I can only keep small crayfish
    who can feed on natural food as small animals and plants
    3-years are put into lakes for crayfishing
    In my lake I have my stock
    and catch crayfish for my ponds and for eating
    today I’ll catch some for stocking my ponds
    these have to be sorted in females and males
    I only need the females
    the difference between male and female
    male has two small legs between his body and tail
    this is his penis
    look at this female - has no penis
    that’s the difference - male to the left and female to the right
    Here’s a crayfish hide
    has been here for months
    it has many crayfish
    most females - they go for stocking the ponds
    Now we will stock some ponds
    this pond gets ten females
    and then two males
    now they can have their weddig here
    I fish crayfish in the ponds at night
    I use a flashlight and a racket
    here’s one
    racket behind it
    a stick to scare it into the racket
    with clear water it’s easy to spot the crayfish
    this way I can catch a hundred crayfish in one hour
    here’s a fry from this year
    I try to keep my stock at ten per sqare meter
    by adding more females if they are less
    and fish more if there are many
    ten per sqm suits the amount of natural food
    and I do’nt need to feed them
    here’s a drone video from my lake and ponds
    my grandson Phillip made it for his granddad
    the lake is for my stock and for fishing
    with sustainable crayfishing
    in the ponds I have my small crayfish
    I catch and put in lakes for crayfishing
    a few years in a lake and they have grown to eating size
    would you like crayfish in your garden?
    but no pond
    then you can make a backyard crayfish farm from raised beds
    with water instead of soil
    just half a meter water is enough
    you can plant water lilies to get beautiful nature in your garden
    four raised beds are enough for a full system
    3 beds for juveniles and one as grow-out pond
    feed with sprouted grain or crayfish pellets from Sveden
    you also need a pond for your stock
    or - you can buy 3-yearlings and feed them a summer
    you only need one pond then
    ten sqm pond should produce fourty crayfish - two kilos
    now we got around to it all
    thanks for watching
    hope I see you again in my next video
