Behaviour, growth and survival of redfish larvae in relation to prey availability
Growth, survival and condition of redfish larvae Sebastes spp., reared in the laboratory (0, 500 1500 and 4500 prey l ‐1 ) were highest in the 1500 prey l ‐1 treatment. Significantly lower larval growth and survival in the 4500 prey l ‐1 treatment corresponded with lower prey bite: orient ratios in...

| Summary: | Growth, survival and condition of redfish larvae Sebastes spp., reared in the laboratory (0, 500 1500 and 4500 prey l ‐1 ) were highest in the 1500 prey l ‐1 treatment. Significantly lower larval growth and survival in the 4500 prey l ‐1 treatment corresponded with lower prey bite: orient ratios in later weeks, suggesting that larvae were unable to forage efficiently at high prey densities. While these prey densities are higher than those reported in the field, naturally co‐occurring Atlantic cod Gadus morhua larvae require higher prey densities when reared under similar conditions in the laboratory. These data suggest that prey availability may not be as limiting to redfish as for other commercially important marine species. |
