If youâ€™ve lived on the Gulf Coast for more than a few years you have seen both commercial and recreational fishing under go some significant changes. For various species and types of fishing there have been increases in length limits, decreases in number allowed, changes in gear types, area restrictions, seasonal closures, turtle and fish excluder devices and closed areas.Every summer the oyster beds are closed due to sewage pollution, there is mercury in our fish, the price of seafood goes up and imported seafood is under cutting our commercial fleet. We charter a boat for half a monthâ€™s rent only to throw back nearly all the fish we catch because they are too small to keep. If youâ€™ve experienced some or all of these then you have probably realized that the oceanâ€™s fishery resources are not infinite.The Gulf Coast is not alone in its resource related problems. The cod fishery in the north Atlantic was closed over 15 years ago and will be closed for another 15 years due to over-fishing. Alaskan salmon runs are down 40% to 60% over the last 20 years. The red snapper season in the Gulf seems close earlier each year. The fish we see in our markets are smaller and are not available for as long. We have to ask ourselves will there be seafood in 20 years and if so what kind?A little history: fishing changed rapidly in the twentieth century especially after WWII. During that war fishing was curtailed all over the globe especially in the Atlantic. When the war was over recreational and commercial fishing expanded rapidly.Nations like the Japan and Russia developed large trans-global distant water fleets of trawlers, long liners, deep-water crabbers and purse seine vessels. Japan, which spent decades collecting oceanographic data, developed new and innovative fishing methods and equipment that greatly increased their catch.There is no planet wide agency that manages and enforces international fishing regulations with any great effect. The United Nations and organizations like the International Committee for the Exploration of the Sea (ICES) make motions in that direction but nothing has been done that has had any real effect on the stocks of fish.The United States has its fishery management councils with their regulations and 200-mile limits but it is a big planet. The bottom line is that a constantly expanding human race is taking more than a finite resource can provide.Aquaculture has and is being touted as a way to fill the gap between the fish that we want and the fish our oceans can provide. Farmers know it is easier and more profitable to â€œraise deer than wolvesâ€ â€“ which are animals that are lower on the food chain and require less intensive care. Fish like mullet, tilapia and the carps (which have been cultured for centuries) will start to fill this gap over the next few years.When and if the stocks now under increasingly strict regulation recover there will never be enough fish to supply our markets like they did in the past without risking a protracted collapse.
