A 3n factorial experiment to evaluate the effects of an abrupt transfer of striped bass, Morone saxatilis, from a closed system rearing facility into a variety of experimental temperature and salinity combinations demonstrated a considerable hardiness of juvenile fish. Striped bass less than two months old had over 80% survival during seven days subsequent to acute introduction from the rearing facility into temperatures of 18 C or 24 C and salinities of 4 ppt or 12 ppt. Relative growth in these treatments was monitored, and the results suggest a degree of flexibility for stocking programs into estuaries.
