Relation of Number of Eggs and Egg Length to Carapace Width in the Brachyuran Crabs Chionoecetes bairdi and C. opilio from the Southeastern Bering Sea and C. opilio from the Gulf of St. Lawrence

Abstract: The number of eggs attached to pleopods of Chionoecetes bairdi and C. opilio from the southeastern Bering Sea increased at a rate proportional to about the 3.4 and 2.7 power of carapace width, respectively, but for C. opilio from the Gulf of St. Lawrence it increased to the 4.2 power. The range in carapace width and number of eggs for crabs from the Bering Sea of a given carapace width were considerably greater for C. bairdi than for C. opilio. In the southeastern Bering Sea, the reproductive potential for adu… Show more

“…This result could be explained by the fact that crab size increased faster than egg number. This result agrees with that reported by several authors (Haynes et al, 1976;Atrill and Hartnoll, 1991;El-Sayed, 1992, 1997, 2004Siddiqui and Ahmed, 1992;El-Sayed et al, 1998, 2014Fouda, 2000;Kotb and Hartnoll, 2002;and El-Sayed et al, 2011) on several crab species. However, contrasting results were recorded by Gotelli et al (1985).…”

“…The fecundity was calculated by counting incubated eggs according to Subramoniam (1982). The relationship between the egg number or absolute fecundity and female carapace width was calculated according to the following formula (Haynes, Karinen, Watson, & Hopson, 1976):…”

“…The spider crab M. forceps seems to be part of those crabs which have low fecundity per brood, and egg number can vary, among crab species, from less then 5,000, described for Aratus pisonii (H. Milne Edwards, 1837) in Jamaica (WARNER, 1967) to more than 4,000,000, as reported by HAYNES et al (1976) for Chionoecetes opilio (Fabricius, 1788) on the Gulf of Saint Lawrence, Canada.…”
