On Sunday, NewsHour Weekend reports from the Big Island of Hawaii, where a proposed bill has ignited renewed discussion about the impact of the state's largest aquarium fishery, which catches hundreds of thousands of gem-like saltwater fish each year for shipment to collectors around the world. Supporters say the industry is sustainable and regulated, and the increased number of collectors, fish taken out and fish still living on the reef are a sign that management is working. But environmental activists say the practice is destructive, depletes populations of popular fish species and fish die by the thousands from reef to retailer. NewsHour's Mike Taibbi reports.
