The body size-specific fecundity of Scyllarides squammosus is described based on the numbers of eggs carried externally on the pleopods of “berried” (ovigerous) females collected during June 1999, at Maro Reef, located mid-chain in the Northwestern Hawaiian Islands (NWHI). Fecundity was positively and nonlinearly related to “tail” (abdomen) width (TW); fecundity ranged from 53,807 to 227,489 eggs in 43 females spanning 52–77-mm TW. The smallest berried female encountered at Maro Reef in 1999 was larger than the smallest berried female observed during most previous years' (1986–97) lobster research cruises. Fecundity of the median-sized (60-mm TW) female caught at Maro Reef in 1999 by the NWHI commercial lobster trap fishery was an estimated 89,660 ± 3,980 (SE) eggs. Brooded eggs averaged 0.67 ± 0.006-mm diameter (range: 0.61–0.77 mm), equivalent to 0.17 and 0.13–0.24 mg, respectively. Egg size was unrelated to female body size. Fecundity and egg size estimates and their body size relationships are briefly compared with other scyllarid lobsters.
