Effects of post-event event effluent on sea fishing

[I-K-E]

there's an age old saying the the sea provides

in an ideal world I'd love to live on a remote section of the coast line
fishing and lobster pots, salt for preserving, sea weed for food and manure and all the other stuff thats washed up

and if your remote enough then hopefully the initial effluent issues would be minimal (live on stores for a while)
