“…Smith and Hines (1991) reported significantly lower foraging rates in blue crabs (Callinectes sapidus) after removal of two chelipeds. Berzins and Caldwell (1983) showed that stomatopods missing two raptorial appendages had a reduced ability to conquer or defend home cavities. The seriousness of such handicap is increased, as is often the case, if by-catch crustaceans are discarded over unsuitable habitats (Evans et al, 1994;Wileman et al, 1999) or repeatedly caught by trawlers.…”

The Clyde Sea Nephrops fishery produces large amounts of invertebrate discards. Of these, as much as 89% are decapod crustaceans, including the swimming crab Liocarcinus depurator (Linnaeus, 1758), the squat lobster Munida rugosa (Fabricius, 1775) and the hermit crab Pagurus bernhardus (Linnaeus, 1758). The short-term mortality of these species was assessed following trawling and periods of aerial exposure on deck (16-90 min), and ranged from 2-25%, with Pagurus bernhardus showing the lowest mortality. Two experiments were performed to determine the longer-term survival of trawled decapods compared to those with experimentally ablated appendages. Deliberately damaged decapods had a significantly lower longerterm survival (ca. 30%) than controls (72-83%). Survival of trawled Liocarcinus depurator that had been induced to autotomize two appendages was slightly lower (74%) compared with intact creel-caught animals (92%). Mortality rates stabilised about 10 d after trawling. Our results suggest that post-trawling mortality of discarded decapod crustaceans has been underestimated in the past, owing to inadequate monitoring periods.

“…Although autotomy of the cheliped is highly effective in immediate benefits for survival (Wasson et al 2002), the loss of the cheliped is known to have negative impacts on subsequent contests (Juanes & Smith 1995). Weaponless crabs have a decreased probability of winning in dyadic contests compared with intact crabs (Berzins & Caldwell 1983, Neil 1985, Smith 1992, Abello et al 1994) even if they are larger in body size than the opponents (Daleo et al 2009) or they have ownership of the resource (Yasuda et al 2011).…”

Abstract:Most crustaceans are known to regenerate their appendages after losing them, and the pattern of regeneration may be related to its function. The pattern of regeneration of the right major cheliped was examined after experimentally induced autotomy and its behavioral function during male-male contests for mates was investigated in the hermit crab Pagurus middendorffii. Males with an autotomized major cheliped regenerated it at the first molt after autotomy and showed smaller growth in body size than in control males. The shape of the regenerated cheliped was more slender than the original, implying that the regenerated major cheliped would be less robust and weaker than previously. The length of the major cheliped of an owner male (guarding a female at the start of a dyadic contest) and the body size of an intruder affected whether or not the contest escalated, but the major cheliped length of the intruder and the body size of the owner determined the outcome of the escalated contest. The intruder used the major cheliped as an offensive weapon to take the female away from the owner by force after the contest escalated. The owner often moved the major cheliped forward, similar to a fencing weapon, before escalation. Such movement of the owner seems to be effective to prevent the intruders from approaching, and the regenerated cheliped of the owner may not require much robustness and strength as a defensive weapon before escalation. Rapid regeneration of the major cheliped in P. middendorffii would therefore be beneficial to minimize the disadvantages incurred by loss of the major cheliped.

“…While such behavior has immediate survival benefits (Dial and Fitzpatrick, 1983;Medel et al, 1988;Smith, 1990a), autotomy may handicap individuals when foraging (Slater and Lawrence, 1980;Smith, 1990a), overwintering (Willis et al, 1982); escaping predators (Vitt et al, 1977;Dial and Fitzpatrick, 1984;Smith, 1990a), or competing for mates (Sekkelsten, 1988;Smith, 1990a) or shelter (Conover and Miller, 1978;Berzins and Caldwell, 1983). Energetic costs of regenerating body parts can reduce reproductive output (Maiorana, 1977) and growth (Kuris and Mager, 1975;Smith, 1990b).…”

Abstract. Blue crab (Callinectes sapidus Rathbun) populations were examined at four sites in Chesapeake Bay and three additional sites along the southeastern Atlantic coast and Gulf of Mexico; the aims were to assess the incidence of limb autotomy and to determine whether injury patterns varied temporally, geographically, and ontogenetically. These data, which include four years of information from one site (Rhode River, Maryland, a subestuary of central Chesapeake Bay), make this study the most extensive and intensive survey oflimb autotomy yet conducted in arthropods. A substantial percentage (17-390/0) of the blue crab populations were either missing or regenerating one or more limbs, suggesting that autotomy is an important mechanism for their survival. The frequency oflimb autotomy varied, both within and between years, and over broad geographical scales. Injury levels were generally correlated positively with crab size. Limb autotomy was independent of sex and molt stage, and frequencies varied little among sites in the Rhode River. Patterns of limb injury in C. sapidus were remarkably consistent among all sites. The most frequent injury involved loss of a single cheliped. Swimming legs suffered the least damage. Severe multiple limb loss was rare. Right and left limbs 'were lost with equal frequency in most populations. This consistency of autotomy pattern suggests differential vulnerability of limbs and standard behavioral response by blue crabs to various injury-causing agents. The frequency of autotomy was density-dependent in the Rhode River, indicating that intraspecific interactions (e.g., cannibalism) may be a major cause of limb Received
