Yes, both are Murano. The fish weight is the first I've ever seen like it. I would really love to own it. The latticino cushion over which the fish "swims" is typical Murano. Of course, there's almost a label that confirms Murano. I believe the Venetian company is Avem - that's its label. The weight is circa 1960s or 1970s.
The more modern millefiori weight is interesting; the canes are a little bit different from the standard, chalkier, colorful canes usually seen in millefiori Muranos. Peg it around mid-1990s or later.
