I live Toronto, and our tap water is fresh water, not salty. I talk for each LB of bivalvia like clams mussels.

  1. How much tap water?

  2. How much salt to add?

  3. What g of salt per LB NEVER to outstrip? What concentration kills them?

For pics, pls see After purge mussels 6 time in salt water 20 mins each, why they still exude much grime?

    To ensure you never kill them, you would need to replicate the water they lived in before they were caught. Ocean salinity varies depending on location.

If you want to simulate seawater, you need 35g per 965g (more or less 1 liter) of fresh water.
