Variable and source Assumption
Vio Brown 1942 Optimum temperatures- are those which
Clemens and Sneed 1957 result in optimum growth. Temperatures
that result in death or no growth are
unsuitable.
V11 Perry and Avault 1968 Salinity levels at which spawning has
Perry 1973 been observed are suitable.
UlZ McCammon and LaFaunce 1961 Optimum temperatures for fry
are those
Moss and Scott 1961 ,
when growth is best. Temperatures that
Macklin and Soule 1964 result in no growth or death are unsuit-
West 1966 able.
Allen and Strawn 1968
Andrews 1972
Starostka and Nelson 1974
VI, Allen and Avault 1970 Salinities that do not reduce growth
of fry and juveniles are optimum.
Salinities that greatly reduce growth
are unsuitable.
V1,, Andrews et al. 1972 Temperatures at which growth of juveniles
Andrews and Stickney 1972 is best are optimum. Temperatures :that
result in no growth or death are unsuit-
able.
Vls Jenkins 1976, ~ Storage ratios correlated with maximum
standing crops are optimum; those cor-
related with lower standing crops are
suboptimum.
U16 Jenkins 1976 Total dissolved solids (TDS) levels cor-
- related-with high standing crops of..warm-
water fish are optimum; those correlated
with lower standing crops are suboptimum.
_' The data used to develop this graph are
_______ primarily from southeastern reservoirs.
U1, Walburg 1971 Flushing rates correlated with reduced
levels of fry abundance are suboptimal.
U1e Miller 1966- "` High velocities near cover objects will
Scott and Grossman- 1.973 decrease the amount of usable habitat
Cross and Collins 1975 around the objects and are thus
considered suboptimum.
