“…Growing interest and debate over the influence of early life history events on population dynamics has popularized the use of retrospective otolith-based techniques for reconstructing aspects of a n individual's early life history (Pannella 1971, Victor 1982, 1986b,c Brothers et al 1983, Campana & Neilson 1985, Wellington & Victor 1989 'Present address: School of Ocean and Earth Science and Technology, University of Hawai'i, Honolulu, Hawai'i 96822, USA.

Daily increment formation in sagittal otoliths, scaling between otolith and somatlc growth. and the temporal link between settlement and formation of a settlement mark in otolith structure were evaluated for their use in reconstructing aspects of the early Me history of the basalt goby Bathygobius coalitus. Formation of daily increments was validated in sagittae of fish ranging In Life history stage from new recruits to sexually differentiated males and females. Total length (TL) was proportional to other measures of body length, width, and depth, and linearly proportionaI to sagitta radius for fish between 8 and 40 mm TL. Somatic-otolith scaling became more curvilinear in larger fish due to declining growth rate of otoliths relative to TL, especially in fish collected during warmer sea surface temperatures. For fish 8 to 40 mm TL, somatic-otolith scaling was not affected by differential somatic growth rates nor by seasonal water temperature. A settlement mark, clearly identifiable as a distinct and abrupt shift in optical focal plane, contrast, and width of daily increments, was venfied to coincide with settlement. Wider post-settlement increments abruptly followed narrower pre-settlement increments across the settlement mark. These results support the use of daily increments, somatic-otolith scaling, and a settlement mark for reconstruction of hatch and settlement dates, mean daily pre-and post-settlement growth rates, size and age at settlement, and post-settlement size-at-age histories for the basalt goby.

“…Adults spawn demersally following a unimodal lunar cycle with year-round reproduction and seasonal reproductive peaks from April to November (Robertson et al 1988). The males of the species provide parental care to the eggs; however, after hatching (*3.5 days), larvae enter the pelagic environment and the pelagic larval duration ranges between 24 and 40 days (Robertson et al 1988;Wellington and Victor 1989). After settlement, the adults are sedentary, defending small feeding territories indefinitely (Myrberg 1972).…”

Local retention, dispersal and fluctuating connectivity among populations of a coral reef fish

et al. 2011

The persistence and resilience of marine populations in the face of disturbances is directly affected by connectivity among populations. Thus, understanding the magnitude and pattern of connections among populations and the temporal variation in these patterns is critical for the effective management and conservation of marine species. Despite recent advances in our understanding of marine connectivity, few empirical studies have directly measured the magnitude or pattern of connections among populations of marine fishes, and none have explicitly investigated temporal variation in demographic connectivity. We use genetic assignment tests to track the dispersal of 456 individual larval fishes to quantify the extent of connectivity, dispersal, self-recruitment and local retention within and among seven populations of a coral reef fish (Stegastes partitus) over a three-year period. We found that some larvae do disperse long distances (*200 km); however, self-recruitment was a regular phenomenon. Importantly, we found that dispersal distances, self-recruitment, local retention and the pattern of connectivity varied significantly among years. Our data highlight the unpredictable nature of connectivity, and underscore the need for more, temporally replicated, empirical measures of connectivity to inform management decisions.
