Rob, check this out --
Blackwell, B.G., B.R.Murphy, and V.M. Pitman. 1995. Suitability of food
resources and physicochemical parameters in the lower Trinity River, Texas,
for paddlefish. J. Freshwater Ecol. 10(2): 163-175.
Paddlefish in the Trinity are interesting. Their early growth is extremely
rapid:
441 mm EFL Age I (vs < 4o0 mm EFL in many pop.s)
747 mm EFL Age II (vs < 600 mm EFL many pop.s)
786 mm EFL Age III
Shallow backwaters with rotifer-dominated zooplankton assemblages may be a
factor.
Also - I believe that Ms Pitman authored some papers on historical
occurrences and biology of paddlefish in Texas, but I do not have these on
hand.
