This is the first of two reports. Puerto Montt, Chile — Five years ago, while much of the world teetered toward an epic economic collapse, this bustling fishing port in southern Chile plunged into a crisis of its own. But, instead of a castrophic failure of banking and real estate, Chileans found themselves dealing with an invisible virus that had travelled literally from the opposite end of the earth.
But inthose pens were infested with a lethal microbe that wiped out millions of fish and threatened to kill the industry. Now those salmon farms are back; Chile expects a new production record this year — a staggeringmetric tons of Atlantic and Pacific salmon.
Using eggs and technology imported from the U. Fueled initially by Japanese investment, maryn mckenna science writer jobs of huge fish farms sprouted along Patagonian shores. The industry grew at a phenomenal rate averaging 25 percent per year. Puerto Montt became a boomtown, employing some 35, people at the farms, processing plants, and fish food factories that converted fish waste and other raw materials into pellets.
Construction boomed as well, with processing plants, thousands of homes for newly arrived workers, and a modern office building with a two-story underground shopping mall.
But aquaculture experts and environmentalists worried that they were growing too fast, taking too many shortcuts with the complex science of fish farming. There were too many farms, packed with too many fish, and not enough biological precautions.
The ISA quickly became an epidemic. Millions of fish died, and millions more had to be destroyed in an attempt to prevent its spread. More than 13, people lost their jobs, forcing many to pack up their families and migrate north in search of work.
But the fish farmers have recovered remarkably fast, due to a combination of strategies. The record exports will be comprised of half Atlantics and half Pacific species.
Individual farms are isolated from each other, with no movement of fish between them. At each stage in the process, workers wear disposable gowns and rubber boots with cleaning stations and foot disinfectant pools at critical points.
The processing plants now resemble surgical wards, with workers draped completely in clean, disposable gear. In the case of aquaculture, it means fish farmers will keep producing more and more fish until the ecosystem collapses. And any ecosystem has a carrying capacity, an ill-defined capacity for how much life can be sustained by the available food and oxygen.

We have to blame it on our lack of knowledge of the carrying capacity.

That led to a small theater company, but after a few years, she realized that a paying job would be a very good idea. When Maryn realized she really wanted to be a writer, she .
