Definitions

  • At least some of the sets of hoist ⁇ ing means may according to the invention comprise at least two tackles activatable from the second side of the net cage immediately adjacent the water level, whereby a particularly simple net cage is obtained.
  • the taking up of the dead fishes is initiated by the set of tackles 27, 28 being activated in the direction shown by means of an arrow 53.
  • the lower end of the first side 26 of the net is pulled obliquely upwards in the direction of the arrow 53 while the dead fishes roll or are pushed forwards to- wards the second side 36 of the net.
  • This activation of the set of tackles 27, 28 continues until the underblock 29 is positioned immediately adjacent the overblock 32, cf. Fig. 5.
