  <dc:description>&lt;p&gt;&lt;span&gt;The insecticidal properties of rotenone and pyrethrum have been known for many years. Both toxicants have long histories of extensive use for control of a variety of insect pests. Rotenone has been also employed as a management tool by fishery biologists to rehabilitate fishing waters, and its toxicity to fish in a number of ecological situations is well established. Pyrethrum's toxicity to fish is less well known.&lt;/span&gt;&lt;/p&gt;</dc:description>
