Specific references to Halibut throughout Geoff Bond's publications.
Up until the 1970s, virtually the only fish on our plates were ones caught in the wild. Now, we have seen the huge volume of fish, notably salmon and trout, that are produced by fish farms. Even so, most other species that we find in our supermarkets (fresh, frozen, or canned) are still wild. Cod, halibut, tuna, sardine, plaice, mackerel, pollock, herring, and many others, for the time being at least, are all caught in the wild. We can say that many of them conform to the Savanna Model while the others, if not conforming, are certainly not harmful. ~Deadly Harvest p.63
