ABSTRACT Fifty-two ovigerous females of Cancer johngarthi were caught from the Baja California Peninsula's western coast, Mexico. Carapace length, carapace width and total weight of each specimen were registered. Fecundity estimates were obtained from the wet weight of eggs in each organism. Mean fecundity was 765,227 eggs, corresponding to a mean carapace width of 117 mm, and the mean relative fecundity was 4,305 eggs per gram of female body weight. Fecundity data (F) were fitted in relation to carapace width (CW) to the power model F = [0.84CW.sup.287], [R.sup.2] = 0.52. C. johngarthi has a high population renewal capacity compared with other larger species like Maiopsis ...
