Depth distribution and spawning pattern of Dissostichus eleginoides over the winter period in Subarea 48.3
may be a small spawning event in April/May. The observed shifts in length at depth may be associated ... with movement of animals to preferred spawning depths. A general model would be that toothfish form ... this depth, dispersing immediately afterwards, mostly upslope. Behaviour appears to be different at ... spawning between the two areas. There may be two (or more) spawning periods during the winter, with the ...
