Live box for breeding fresh-water crawfish in lentic waters

摘要

the notification is podchowu freshwater crayfish floating cages in age 0 + and 1 + in water reservoirs stagnuju0105cych (lakes, ponds). application of solid cage offers the opportunity to control growth and survival and yield podchowywanych carcinomas at any time farming.skeleton cage is welded steel bars on the rigid structure of rectangular dimensions of zaraczeniowej density dependent. in the structure described above is sieciarska skeleton cage open fabric, designed the closure of soot from the internal water tank.the fabric is in the form of a grid of plastic mesh side situated in the range from 0.5 to 2.5 mm (depending on the species podchowywanego cancer). since the soot soot provides a rigid grid surface stiffness dna (metal or plastic) permanently affixed to the base. the above described structure embedded in soot is pu0142ywaku (7), with the piping.a float (7) is built on the rectangle whose internal dimensions are larger than the soot of approximately 5 - 10 cm. a float (7) is made of tightly combined pipe hollow (air at atmospheric pressure), made from a material providing sufficient stiffness and buoyancy.displacement float should be selected so as to maintain the surface structure probably drowning cage.
