Are you sure that your cooking and food preparation techniques do not
alter the salt/water composition of your food?  Try catching them
fresh out of the ocean and eating them with no preparation.

If you drain the blood/hemolymph fluids, which are high in NaCl, the
actual tissue is low in Na+ but high in K+.  It has the same osmotic
pressure (salinity) as seawater and so has the same osmotic effect on
the body, but without the sodium loading.
