  • Salmon lice are a real threat to aquaculture and wild fish populations

    August/September 2015 issue

    Attached to the host, the lice use their rasping mouth to graze and remove mucus, skin and tissue. Strongly attacked host fish may lose their appetite and growth, and the stress and wounds expose fish to secondary infections.

  • Essential ingredient to a successful world – SEAFOOD!

    August/September 2015 issue

  • Thanks be to soy

    June/ July 2015 issue

    The next time that you are sufficiently lucky to be sitting down to a bowl of tofu, or platter of edamame, or… if you are particularly lucky… to a fillet of delicious, nutritious, soy-fed fish, then I would urge you to please spare a moment, to bow your head, and… if you are so inclined… offer a quiet word of gratitude to the Great Whomsoever-to-Whom-you-whisper-your-deepest-secrets-and-desires.

  • Stock Replenishment of Marine Fishes as a Springboard to Commercialization?

    June/ July 2015 issue

    Historically, the “secrets” to culturing many of the fishes currently reared in the U.S. were unlocked through efforts to replenish or enhance wild populations for the benefit of commercial and recreation fishermen.In many cases this culture capacity went on to fuel successful aquaculture ventures because the fish were obviously valued – not only for sport but also as food. Unlike other parts of the world, in the U.S. there are only a handful of organizations culturing marine fish for stock replenishment. I recently reached out to some of those groups to see what species they were culturing and what interest, if any, was being exhibited by the commercial sector for farming applications.
