“…Indeed, abalone have numerous predators such as sea otters (Hines & Pearse 1982), crabs, stingrays, fish (Shepherd 1973, Griffiths & Gosselin 2008 and starfish (Cox 1962, Day et al 1995. Day et al (1995) described escape responses exhibited by Haliotis rubra when attacked by star fish: extension of their tentacles to detect the predator is followed by retraction of the tentacles when contact is made with the starfish tube feet, then lifting of its shell followed by violent twists of the shell from one side to the other to break the starfish's grip, almost always followed by a 'running' response. In addition, abalone often eject mucus, which probably helps to mask the direction of escape and might have repellent proprieties (Day et al 1995, Bancalà 2009).…”

Domestication of Haliotis tuberculata has only recently begun. During the process, we expect that behavioural and physiological traits may evolve to become more adapted to their captive environment. These modifications may result from intentional selection of production traits or unconscious and unintentional selection due to conditions experienced in the farm environment. To study this process at the earliest stage, the progeny of 3 different broodstocks obtained from wild parents, selected farmed abalone and randomly sampled farmed abalone, were studied. After rearing for 16 mo in separate tanks, offspring from the 3 progenies were placed together in sea cages at the same density. After 3 yr, behavioural traits were studied, and the immune status after a stress situation was assessed. Mortality and growth were also recorded. In spite of the fact that no significant differences were observed in survival, growth or immune status traits between the 3 progenies, less progeny from the selected broodstock performed the complete sequence of anti-predation behaviour, and they took more time to reach their hides compared to the wild progeny. In addition, the shell colours of the selected progeny were more orange and had more stripes compared to the brown-green colour of the wild progeny. Progeny of randomly sampled broodstock showed intermediate responses between those of wild and selected progeny. Our results suggest that associated behavioural trade-offs can take place after only one generation of selection to improve growth. This should be taken into consideration when using selected stocks for ranching or population enhancement programs.

“…Previous papers reported that crabs (Griffiths & Gosselin, ; Schiel & Welden, ), lobsters (Pederson, Barrett, Frusher, & Buxton, ; Schiel & Welden, ), and starfishes (Day, Dowell, Sant, Klemke, & Shaw, ; Griffiths & Gosselin, ; Schiel & Welden, ) are important predators on juveniles of abalone species. For juveniles of H. discus hannai <50 mm SL, their sympatric predators in the subtidal zone have been focused on to understand factors affecting survival of hatchery‐reared seeds released into natural habitats, and starfishes ( Lysastrosoma anthosticta and Aphelasterias japonica ) and kelp crab Pugettia quadridens were reported to be the main predators of juveniles (Hoshikawa, ).…”

We conducted field surveys to study avian predation on invertebrates inhabiting the intertidal and shallow subtidal zones in Otsuchi Bay on the Sanriku Coast. The black‐tailed gull Larus crassirostris was the most frequently observed avian predator, and we observed the gull actively foraging on benthic invertebrates at the study site. In particular, we found frequent predation activities by the black‐tailed gull on the abalone Haliotis discus hannnai. The abalone accounted for 56.3% of the total amount of the prey remains, and the sea urchin Strongylocentrotus intermedius and mussel Mytilus galloprovincialis were also major components of the prey remains and accounted for 14.6% and 11.8% of the total number, respectively. While the gull preys on the abalone over a wide size range (27.0–105.7 mm shell length), smaller size class abalone individuals (<40 mm shell length) were dominant in prey remains compared to the live abalone surveyed in the surrounding habitats. Among four time periods in a day, predation rate on the abalone was highest in the late afternoon. Predation rate on the abalone was higher on rising tides than falling tides, although no clear relationship was confirmed between the predation rate and the tidal height. The predation by the black‐tailed gull might have large impacts on the shallow rocky reef ecosystem.

“…However, this asteroid has been observed to feed readily upon ophiuroids, gastropods, and mussels under laboratory conditions (Swenson, personal observation). In addition, the diet of a congener, C. calamaria, includes bivalves, gastropods, crustaceans, ascidians, echinoderms, and carrion (Keough and Butler, 1979;Day et al, 1995). We selected C. tenuispina because it is a highly mobile, predatory asteroid.…”
