Not neccessarily. Look at the problems they have with some of the big
cats. Some display quite low fecundity. The debate still continues
today as to why.

What?? Kill one of Australia's most Endangered fish just to find out
what is in their stomachs! Bruce, I'm most surprised. :-) (poke poke)
I'm sure you really meant that we should try to examine some of the
specimens that exist in Museum collections and to take a closer look at
their stomach length and gill raker type to try and predict the foods
that they consumre.

The temperature is extremely variable depending upon the time of year.
In December at 6 am water temp in the type locality was 17oC, by 10 am it
was at 31oC! I think Rob found a variation as high as 21oC over a day.
Few fish in the world experience such extreme temperature changes every
day of their lives.

You just have sh*t on the brain Bruce. :-)
