Heritability of personality traits in dumpling squid (Euprymna tasmanica) and fitness-related consequences
This study used crosses of wild-caught dumpling squid (Euprymna tasmanica) males to multiple females with known behavioural types to evaluate patterns of additive and residual variance in behavioural traits from offspring under two contexts - a threat and a foraging test.
Genetic contributions to behavioural expression were context-dependent. Threat context behaviour had significant heritability, while foraging context behaviour had lesser additive and greater residual components.
Female trait variation was not correlated with fecundity. Female foraging boldness (which co-varied with size) explained some variation in brood hatching success. Positive assortion of mate pairs according to shy-bold phenotype determined fertilization success.

- The purpose of this study was to examine the heritability of personality traits in the dumpling squid (Euprymna tasmanica) and whether a female's personality type influenced reproductive output.

- Statement
- ANIMAL COLLECTION AND MAINTENANCE Adult dumpling squid (Euprymna tasmanica) were collected from 2 wild populations in Tasmania, south eastern Australia (Kelso and Margate). Squid were maintained in a 2400-L closed seawater system at the University of Tasmania (Launceston), but housed separately. They were subject to behavioural tests and then mated 2 weeks after capture. Eggs were deposited on PVC pipe and were incubated at 18 degrees celcius until hatching (35-40 days). BEHAVIOURAL TESTING Individuals were subjected to 2 behavioural tests conducted on separate days within a week of capture. Test duration for both was 5 minutes, when frequency and duration of behaviours were recorded. THREAT TEST: the experimenter touched the squid on one of its arms up to 10 times or until it moved away. Behaviours recorded were: number of touches required before the squid moved away, the first behavioural response towards the stimulus (1=jet, 2=fin swim, 3=amble, 4=ink, 5=bury, 6=no reaction, 7=colour change, 8=arm flower posture, 9=grab), jetting frequency, number of times the stimulus was grabbed and frequency of arm flower postures. FEEDING TEST: Live food (mysid shrimp) were presented to each squid. Behaviours recorded were: latency to feed, number of feeding attempts and handling time (number captured/total time spent feeding).
