“…9). Spencer and Gough (1978) found similar G3o values for Ostrea edulis of the same initial live weight grown in tray culture (North Wales). Other tray cultures from North Wales, starting with small spat (1.2 to 5.7 mg live wt) found higher G3o values (Utting 1988).…”

“…Part of the variance in the mean relative growth was due to the dependence of growth rate on initial size. This relationship was examined further using a single growth coefficient (G3o) for the entire study period, normalized to a monthly rate (Spencer and Gough 1978):…”

“…Spencer & Gough (1978) found little overall difference between the growth or survival of Crassostrea gigas Thunberg or Ostrea edulis L. held subtidally from rafts versus intertidal trays subjected to low levels of emersion (5 %). Roland & Albrecht (1986) measured reduced growth rates of C. gigas at +2.1 m compared with +0.9 to 1.2 m, while Surnner (1981) similarly found higher growth in subtidally grown oysters over 3 mo.…”

Survival and growth of newly settled oysters were measured at sub-and mtertidal treatment levels during the first month of post-settlement life in the York River, Virginia, USA. Controlled settlement of hatchery-reared larvae m the laboratory and image analysis techniques allowed for individual oysters grown in the field to be tracked through time. High mortality occurred within 1 wk postsettlement at all tidal heights m 3 experiments which spanned the natural recruitment period. This imtial mortality strongly influenced later abundance, as weekly mortality rates decreased sharply after 2 wk. Additionally, all recruits were eliminated from the mid-intertidal zone and above (>25 % aerial exposure) during high temperature periods. Only in autumn did recruitment occur in the mtertidal area occupied by natural oyster populations. In contrast, low intertidal and subtidal populations persisted through the month long experiments where adult oysters were rare Growth (shell area) of intertidal oysters exposed >25 % was reduced relative to more immersed oysters. Density-dependent growth was not observed While the natural oyster population appeared to b e relegated to the suboptimum mtertidal, successful recruitment to this zone was limited on a seasonal basis by lethal air temperatures >30Â°C The mortality agents which structure the mtertidal population affect recently settled and juvenile oysters

“…During the study period the temperature ranged between 9.2 and 18°C, well within the range for optimal growth rate (Quayle & Newkirk 1989). There was a significant correlation between water temperature and growth rate of O. chilensis as has been reported also in Ostrea edulis and Crassostrea gigas (Spencer & Gough 1978;Utting 1988). However, a major difficulty in correlating temperature and growth rate in field populations of bivalves is that the correlation, even if it is significant, may not be causal (Wilson 1977;Page & Hubbard 1987).…”

The phytoplankton community of the Putemun Channel (southern Chile) and its correlation with some environmental variables is analysed in this paper. Samples were collected on a monthly basis from May 1991 to May 1993. A total of 121 phytoplanktonic species were identified. The phytoplankton cell abundance ranged between 3.5 × 10 4 cells/litre and 11.2 × 10 6 cells/litre. The phytoplankton community was characterised by the dominance of diatoms. An inverse relationship between temperature and species diversity was observed. A significant correlation, after excluding tychoplanktonic benthic forms, was found between chlorophyll a, cell abundances, and temperature. The influence of biotic and abiotic variables on oyster (Ostrea chilensis (Philippi 1845)) growth was analysed. The instantaneous growth rate was found to be positively correlated with both temperature and phytoplankton abundance, whereas significant negative correlation between growth and amount of particulate inorganic matter was found.
