The sea water that provides seaweed with nutrients also carries bacteria, viruses, and fungi. As a defense against these organisms, it is thought that seaweed synthesizes an arsenal of chemical compounds, and these in turn can be used by garden plants.he sea water that provides seaweed with nutrients also carries bacteria, viruses, and fungi.

Cod should be baked at about 350 degrees for 10 to 15 minutes. This is more than sufficient cooking time since cod is a delicate fish and is easily overcooked. When in doubt, if the fish flakes easily with a fork it is finished cooking and ready to eat.
Fish has always had one temperature for being done. The internal temperature for a done fish should be 145 degrees. At this temperature the fish should be opaque throughout and flake easily when tested with a fork. Like you, I prefer my Salmon to be medium, so the internal temperature will not be 145. As far as the internal temperature for other fish. I think you will need to test some fish to find the right internal temperature for the way you like your fish cooked. I know that on Cod and Halibut, I under cook mine a little so it is moister. But I never have checked the temperature, but will next time.
