In fact, the aforementioned criteria constitute a non-permit required confined space. A permit required confined space â more specifically, entrance to a permit required confined space â should be limited only to workers with the proper permit. This is due to the inherent hazards within this type of confined space.
Salmon farming is a type of aquaculture where the fish are grown in net cages, typically located in sheltered bays and fjords along the coast. Salmon are hatched in brood hatcheries and grown in freshwater until they are large enough to transfer to marine pens.
The net result is greatly accelerated depletion of the numbers of fish in the oceans. That is why I have recommended choosing wild Alaskan salmon. It tastes better, is more nutritious than farmed Atlantic salmon, and eating it does not have the environmental impact or health consequences of relying on farmed salmon. The news that Seafood WATCH has approved the new salmon farming technique is certainly welcome. I understand that this action followed several months of investigation by scientists who inspected the production facilities and reviewed feed ratios, fish contaminant and pollution discharge levels at the salmon farms.
