Includes bibliographical references (pages 6-7). "Templeman (1944) suggested that relative abdomen width could be used to determine size at which female lobsters mature. Although there is considerable evidence in support of this concept, no one has previously defined the exact relationship between abdominal width and maturity. Abdomen width expressed as a percentage of carapace length (AWI) is used as a female maturity index. Through the correlation of abdomen width index (AWI) and stage of ovary development, we have been able to show that 50% of females with an AWI of 65 are potentially mature (capable of extruding eggs in the current season)"--Abstract.
