Scientists explore marine ecosystems that are changing as a result of ever-growing fishing pressures. This case study and its compelling underwater footage document how the harvest of sea urchins off the coast of Maine impacts other species in that marine community. Scientist-divers track predator-prey balances and life cycle events such as spawning. By studying a complete ecosystem as well as species life cycles, the methods, timing and location of harvest can be adjusted to promote sustainable practices.
