Fun puzzle - felt there should be a huge fish move on 5 somewhere - but in the end played these two steps...

Not huge, but the finned X-Wing in c24 might have been helpful if you hadn't found your second move.

Danny, I did see the grouped kite r4/c4 - which does the same damage I think - plus some grouped transports. But it never took out one of the bilocal 5s as I was hoping for..

All of the bilocals contribute to a stable cycle after all fish eliminations. Some puzzles just don't want to cooperate! _ Very Happy _

Code:
 stable cycle (*)

UR 47 boxes36; r89c9<>47
X-Wing (5)
UR 14 boxes39; each solution solves box 1
W-Wing (57)
