“…A female may make it more dicult for a male to control her to insure that she mates with a large male (Shuster 1981). In blue crabs and many other species, a male's size in¯uences his ability to, (1) guard and/or protect the female during takeover attempts (Ridley and Thompson 1979;Berrill and Arsenault 1982;Ward 1983a;Berrill and Arsenault 1984;Jivo and Hines 1998), which might result in damage to her (Borgia 1981;Smith 1992); (2) physically carry the female (Adams and Greenwood 1987;Crespi 1989) or copulate with her (Beninger et al 1991);and/or (3) provide her with a large quantity of sperm (Wilber 1987;Sainte-Marie 1993;Jivo 1995). Therefore, female resistance may represent a strategy for mating dierentially with large males.…”

In many species, males and females actively participate in courtship, and the outcome of pre-mating interactions in¯uences the mating success of both sexes. Female blue crabs, Callinectes sapidus, mate soon after their ®nal molt to maturity; thus female molt stage dictates the timing of mating. In a ®eld experiment, we manipulated female molt stage and sex ratio to test their eects on the courtship behavior of both sexes, if female behavior in¯uences the behavior and pairing success of males, and if male courtship in¯uences male pairingsuccess. Early-molt-stage females avoided males during courtship, whereas late-molt-stage females sought out males. As a result, males had to pursue and capture early-molt-stage females whereas males displayed to late-molt-stage females and more easily physically controlled them. Males sometimes abandoned late-moltstage females, but this occurred more often when females were abundant. The rate at which females avoided males was positively correlated with that of males abandoning females, and males that were unsuccessful at pairing met with higher rates of female resistance than successful males, suggesting that female behavior in¯u-ences male pairing-success. Unlike unsuccessful males, successful males more often made the transition between display and maintaining physical control of the female. At high male sex ratios, males initiated courtship more readily; thus both sexual competition and female behavior in¯uence male courtship in this species.

“…As a result, search times for non-virgins may be high and/or encounter rates may be low. Non-virgins may seek out additional males to mate with if they are released while still vulnerable to predation or if, as in a variety of other species, they receive a small amount of sperm (Gromko et al 1984;Simmons 1988;Waddy and Aiken 1990;Sainte-Marie 1993). Otherwise, non-virgins may resist the mating advances of males because paired females miss feeding opportunities necessary for growth after molting.…”

“…Postcopulatory mate guarding occurs in many crabs but its role in sperm competition has rarely been examined, despite evidence that sperm competition may occur in crabs (Salmon 1983;Christy 1987;Diesel 1991;Koga et al 1993). In some species, females mate with multiple partners (Murai et al 1987;Brockmann 1990;Diesel 1991;Henmi et al 1993), females store sperm for extended periods of time (Paul 1984;Bauer 1986;Diesel 1988;Sainte-Marie 1993), and male ejaculates harden to form what may be a sperm plug (Bigford 1979;Elner et al 1980;Bawab and El-Sherief 1989;Diesel 1990). If the hardened ejaculate prevents other males from mating with the female, the duration of guarding may coincide with sperm plug formation.…”

“…Such harvesting affects the demography of the population by skewing the sex ratio towards females and decreasing mean male body size (Smith and Jamieson 1991;Abbe and Stagg 1996;Rowe and Hutchings 2003;Pillans et al 2005;Fenberg and Roy 2008). In such harvested populations, small males replace large males in reproduction and remaining males participate in more matings than in pristine populations (Ennis et al 1990;Sainte-Marie 1993;Carver et al 2005;Milner et al 2007). Therefore, the sperm availability would decrease sharply in large male-selective harvested populations consisting of smaller males and with female-biased sex ratio, which can decrease the reproductive success of females.…”

Keywordsbeen reported in many species of vertebrates and invertebrates (e.g. Bianchi et al. 2000;Branch and Odendaal 2003;Roy et al. 2003;Harvey et al. 2006).In a wide range of taxa, body size is one of the key determinants of fitness in both males and females (Andersson 1994). For example, body size is positively correlated with reproductive fitness (e.g. mating success and fecundity). Mostly, larger males are stronger competitors for females (e.g. Hoefler 2007) or can provide more ejaculated sperm (e.g. Jivoff 1997), or better care for the offspring (e.g. Kolm 2002). In females, body size positively correlates with egg size (e.g. Einum and Fleming 1999), number of spawning (e.g. Claramunt et al. 2007), number of eggs spawned (e.g. Evans et al. 2008), or quality of larvae (e.g. Berkeley et al. 2004). Therefore, mate choice is non-random in the majority of animal species (Real 1990), and males and females prefer larger mates mutually (e.g. Sandvik et al. 2000;Herdman et al. 2004; Aquiloni and Gherardi AbstractTo signal a need for caution for present large male-selective harvesting practices, negative impacts of the large male-selective harvesting on reproductive output in large decapod crustacean resources are introduced with emphasis on my own work with spiny king crab Paralithodes brevipes, coconut crab Birgus latro, and the stone crab Hapalogaster dentata. The large male-selective harvestings for several large decapod crustaceans have changed their population demographic structure by decreasing mean male size and skewing sex ratio towards females. By several field and laboratory experiments, the change of population demographic structure was anticipated to decrease female reproductive success in the resources (i.e. reproductive output of the harvested populations) through a decrease in sperm availability for females because of male size-dependent reproductive potentials and slow sperm recovery rate. Furthermore, reproductive output and stability of the large male-selective harvested resources were also anticipated to decline by a decrease in mate availability for females, attributing to combination of female mate choice for larger males with negative effects of female delayed mating and/or maternal influences. To establish the optimal management practices, the details of the mating system and reproductive ecology of each targeted species should be investigated.
