Explanations for answers to quiz on gonadosomatic-index decrease in non-ovigerous Metacarcinus magister females:

Gonads are absorbed.  Yes.  This is explanation favoured by the authors.  Otherwise, gonads would have continued to grow preparatory to eggs being extruded in late autumn (see orange-dotted line on graph in the Research Study).

Body mass increases.  No.  This is determined in a comparison of gonad and body masses in September and October by the authors, which indicates that the decrease in gonadosomatic index is not a result of increase in body mass.

Eggs are extruded but not held by the female, perhaps because they are not fertilised.  Good try, but there is no evidence that this happens.
