Collection of catch data is fundamental to themanagement of a fishery. A sample of catch data is collected each month from fishers on-site at Glover’s Reef. Data are collected on lobster, conch and finfish, and more than 300 fishers have participated in the program. Data are collected using standardized data sheets and include information on species, size and weight, gear type, effort, and area fished. From these data we can determine catch-per-unit-effort (CPUE) for the most important commercial species and observe trends over the years. The data collection started in August 2004 with a pilot survey and has continued since 2005, on a monthly basis (see Fisheries Catch Report). These catch data are also contributing to the development of a sustainable level of catch for lobster and conch for the atoll (see Spiny Lobster Catch Quota Report).
