“…The lack of cannibalism of eggs and young in brooding females of C. quadricarinatus in this study is in accord with previous reports on female crayfish (Scudamore, 1948;Little, 1975: Bechler, 1981Figler et al, 1995Figler et al, , 1997. The only two incidents of feeding on few eggs and young observed in our study may have been due to the eggs being nonfertilized, diseased, or the young being dead.…”

Mother-offspring relationships were studied in the red-claw crayfish Cherax quadricarinatus during 3 phases: "egg-carrying," "hatching," and "release." The maternal behavior of 16 females and the dispersal of their young were monitored with a video camera in small-and large-sized aquaria. Time allocated to locomotion, aeration, and cleaning was computed for each phase. During the release phase there was an increase in mobility and a reduction in time devoted to fanning as compared to the egg-carrying and hatching phases. A significant negative linear regression was found between the number of juveniles on the mother and days since release. Mother-offspring association was considerably prolonged under conditions of limited space, resulting in a delay in the next breeding cycle of the female. The implications of this study for the commercial production of redclaw crayfish arc discussed.

“…Females carrying eggs and juveniles are not cannibalistic. However, they are more aggressive toward other crayfish than nonreproductive females, probably as a mechanism for protecting their young (Burba, 1983;Figler et al, 1995Figler et al, , 1997Levi, 1997).…”

“…Normally sex differences play an important role in the outcome of aggressive interactions. In general males are dominant over females (Ameyaw-Akumfi 1976;Figler et al 1995aFigler et al , 1995b, but 'a reproductive status advantage' is found in P. leniusculus and Procambarus clarkii, where berried females are more aggressive (Peeke et al 1995;Figler et al 1997) than non-berried females and males since they need shelters to incubate and safeguard their eggs. They fight intensively to establish dominance hierarchy over non-maternal females and even adult males (Leimar and Enquist 1984;Ranta and Lindström 1993).…”

Sheltering behaviour of Macrobrachium nobilii (Henderson and Matthai, 1910)

Shelter acquisition seems to be one of the main causes for agonistic interactions in the communal culturing of decapod crustaceans, leading to reduction in survival and growth-rate values. Understanding how to reduce aggressive behaviour among individuals by providing suitable shelters would promote production efficiency and welfare in such aquaculture environments. Factors influencing the sheltering behaviour of a freshwater prawn, Macrobrachium nobilii, were studied in laboratory conditions. Prior ownership significantly increased the ability to retain a shelter; males were significantly more likely to acquire and retain a shelter than females, except females carrying eggs. Various movements of the prawn while acquiring the shelter and the behaviour pattern involved in evicting an occupant are described. The size of the shelter selected by an animal is directly related to its body size. Regarding the choice of the colour of the shelter, juveniles and adults preferred dark shelters over light-coloured shelters and never chose a transparent shelter.

“…The present knowledge of crayfish behaviour has thus emerged largely from studies conducted under controlled laboratory settings. Such work has addressed defensive responses to predator cues (Stein & Magnuson, 1976;Bouwma & Hazlett, 2001;Herberholz et al, 2004), the influence of shelter and season on diel activity patterns (Westin & Gydemo, 1988;Barbaresi & Gherardi, 2001), and individual behaviours in social contexts including mating (Mason, 1970;Berrill & Arsenault, 1982, maternal behaviour (Hazlett, 1983;Figler et al, 1997Figler et al, , 2001Levi et al, 1999), and aggressive interactions (Rubenstein & Hazlet, 1974;Huber et al, 2001a).…”

SummaryAgonistic behaviour of crayfish has been studied extensively in laboratory settings where pairs or groups of individuals are allowed to interact within an experimental arena. Crayfish agonistic behaviour within its natural context, however, has received little attention to date. The present, non-manipulative field study explored activity patterns, behavioural repertoires, and agonistic encounters of rusty crayfish (Orconectes rusticus) during the summer months using continuous, 24-hour, underwater video recording at a series of representative field sites. Following the filming, crayfish within the vicinity of the camera site were captured and measured. Individual densities were high, reaching a maximum of 68 individuals/m 2 at some sites. Large crayfish predominantly inhabited deeper sections of the river and were mostly active at night, whereas small crayfish generally utilized the shallows and were active outside their burrows during day and dusk. Time outside their shelter was mainly used for feeding. Individuals frequently returned to the same shelter they had emerged from. Agonistic encounters were common events and generally occurred in the context of shelter acquisition or defense. Dyadic fighting progressed with escalating sequences of stereotyped aggressive acts. Furthermore, high intensities with unrestrained use of claws were seen in encounters between size-matched opponents. The results of this study allow us to root laboratory findings of crayfish aggression within a comprehensive, ethological framework and to consider ultimate consequences for individual fighting decisions and strategies.
