Caught in a Net? Takeaways In the last two decades, shrimp farming has become one of the fastest growing areas of the fish farming industry. Travelling south in a bouncing bus towards Hue from Halong Bay, where the pitted limestone islands soar out of the sea like rotting dragon’s teeth, the coastal plain is dotted with huts on stilts, platforms running around them. During low tide, they stand on dry land. At high tide they’re surrounded by water. Nets and string cages hang beneath the platforms. More wrap the stilts, each one seething and undulating with life. These are domestic versions of a fish farm, designed to produce enough catfish, squid, crab and the area’s ubiquitous shrimp to feed the family. And families thousands of miles away.
