“…The home ranges of the fish after homing were restricted and were associated with the vertical wall and the rocky area (Fig.2). Black rockfish generally inhabit rocky areas, which they rarely leave (Harada, 1962;Shinomiya and Ezaki, 1991;Mitamura et al, 2009). These results suggest that the release site was indeed outside the home ranges of the fish, or at least was rarely visited by the rockfish.…”

“…In this study, four of eight straight-homing start points were outside the estimated home ranges. In general, black rockfish inhabit small, rocky areas (Harada, 1962;Shinomiya and Ezaki, 1991). The home ranges predicted here were characterised as rocky areas with a vertical wall.…”

“…This species grows relatively slowly, is long-lived and abundant in rocky areas, and is a typical site-specific fish that utilises a rock crevice or hole for shelter within a small home range (Mio, 1960;Harada, 1962;Hatanaka and Iizuka, 1962;Numachi, 1971;Utagawa and Taniuchi, 1999;Mitamura et al, 2009). Our comparative study on the homing behaviour of vision-blocked and olfactory-ablated rockfish revealed that the rockfish primarily used olfaction to navigate back to their original habitat from outside the home range (Mitamura et al, 2005).…”

SUMMARYSedentary and territorial rockfish of the genus Sebastes exhibit distinctive homing ability and can travel back to an original location after displacements of metres or even kilometres. However, little is known about the behavioural and sensory mechanisms involved in homing. Although our previous study demonstrated that nocturnal black rockfish Sebastes cheni predominantly use their olfactory sense for homing from an unfamiliar area, the possibility of using landmarks in a familiar area cannot be discounted; i.e. site-specific fish are likely to use three-dimensional spatial memory for navigation and orientation. Using high-resolution acoustic telemetry, we investigated whether S. cheni exhibit distinctive homing paths. Results show that all of the eight rockfish increased their effort within a small area of an unfamiliar region around the release site just after displacement, suggesting that the rockfish probably searched for the homeward direction. The rockfish showed the search movement in the upstream and/or downstream direction, which did not lead home. Finally, after returning to their familiar area, the rockfish exhibited more directed movements with faster speeds at a shallower depth, which was similar to the depth utilised in daily life as well as that of the fish capture.

“…3. Other stations for supplemental divings: The diving stations in Kasaoka Bay are already described by FusE (1962 a, b) and HARADA (1962) -120-km 2 km inaccessible to me were gathered from fishermen and used as data for discussion after close selection. Especially I appreciate those offered by Mr. IwAKI, a skillful fisherman in Shirahama, since they gave me sometimes important clues and precise knowledge on the behaviors of fishes in Tanabe Bay.…”

“…Various studies have shown that black rockfish are most territorial during the reproductive season, with larger males chasing smaller individuals and thus limiting their territories (Shinomiya and Ezaki, 1991;Harada, 1962). It is possible that the fish we sampled are sub-adults and that some were chased away by larger individuals from an area saturated in territories.…”

Movement of Selected Nearshore Temperate Reef Fishes Along California's Central Coast

Worldwide fisheries decline has spurred the utilization of new conservation and management approaches, including the implementation of marine reserves. The diversity of goals and expected outcomes should guide the marine reserve design process, coupled with a thorough understanding of the ecology of all species targeted for protection.Central California's network of coastal marine protected areas (MPAs) was established in an environment of some uncertainty regarding the expected outcomes for temperate nearshore fish species, especially the Sebastes genus (rockfishes). Movement behavior of temperate reef-fishes plays an important role in the level of protection that a reserve will afford a species. Consistent small-scale movements (<10 km) and limited home range sizes decrease the likelihood that individuals will encounter fishing mortality.Conversely, large-scale movements outside of reserve boundaries may contribute to fisheries in surrounding waters ('spillover').The current study sought to further elucidate the movement behavior of some shallow-water temperate reef fish species throughout California's central coast, with goals of providing useful data for future MPA design processes. Tag-and-recapture methodology was utilized in order to observe fish movements, centered on a public participation program for acquiring information on recaptured tagged fishes. A total of v 476 fishes representing 14 species were recaptured from a sample of 37,111 tagged (1.3%) over a five-year period spanning [2005][2006][2007][2008][2009]. The majority (75%) of distances traveled were less than one kilometer, however some species made consistent far-ranging travels on the order of hundreds of kilometers as well. Analyses of factors with potential for shaping movement behavior included geographic variation, source of recapture data, gear type, days at liberty, length, initial capture depth, handling condition, and fish density. Additionally, the applicability of tag-and-recapture methodology is examined as an effective source of fish movement information. The results of this research corroborate findings of previous studies as well as provide new insight into the movement patterns of some nearshore temperate reef species.vi ACKNOWLEDGEMENTS
