Although sustainable fishing practices are a rarity in our environmentally threatened world, some can be found. This program searches out fishing industries that take steps to protect delicate ecosystems. In the Canary Islands, fishermen use hook-and-line methods for high market-value species and take only fully mature fish. In Oman, the authorities closely monitor catch sizes as well as what types of boats and nets are used. In one small British village, a 70-year-old injunction allowing only sail power along the coast has prevented the over-exploitation of fish and oyster beds. Interviews with leading policy-makers elicit a growing awareness that drastic action must be taken to protect ocean fish stocks-although in almost all cases, these measures fall short of what is needed to avert a planetary crisis.
