Seaweed from supermarket for fish?

[Freezekougra]

I saw 3 types:
Dried kelp: Ingredients list says only kelp seaweed, but it has 10% sodium/serving
Dried seaweed: 3% sodium, no ingredients list
Dried laver: 1.5% sodium, no ingredients list

Will this be beneficial to fish? Do you think fish will readily accept it? I might want to try a gel based food with agar and seaweed
