Techniques to Monitor Recruitment of Postlarval Spiny Lobsters,'Panulirus argus', to the Florida Keys

摘要

Monitoring of postlarval spiny lobster recruitment using floating artificial habitat collectors requires that collectors be pervious to fouling organisms for at least two months prior to deployment. Sampling is necessary during new moon and first quarter phases of each lunar month. Two collectors sampled at 2-3 day intervals should indicate peak recruitment and relative abundance at an appropriately selected station. Results obtained while testing monitoring techniques confirmed that significantly greater recruitment occurs during spring. Abnormally high recruitment followed a severe temperature drop.
