Hi Peter and All=0AInteresting about the squid.=0AAlso numerous reports of =
Bluefish in Minas Basin. Quite rare to get them there and=0Ausually they do=
n't come to NS until August. They prey on squid and follow them around.=0AT=
here is reports of the water being warmer than usual in the Minas Basin als=
o but=0Ahow accurate these reports I don't know.=0AAn interesting summer!=
