Conduct investigations to describe movements and behavior.

Map existing areas providing important habitat requirements.

Obtain an artist's descriptive key of developing larvae and
early juveniles of pallid sturgeon, shovel nose sturgeon, and
shovel nose X pallid hybrids.

Determine reliable, nonlethal aging techniques.

Research additional solutions to the impacts of man's activities
on pallid sturgeon and their habitat.

2.2.1. Identify priority areas and needs for restoring the diversity
of riverine floodplain habitats. .

2.2.2. Develop simulation models for operation of main stem Missouri
River and tributary dams to benefit pallid sturgeon and provide
for other uses.

2.2.3. Design multi-level releases from main stem Missouri River
reservoirs.

2.2.4. Develop pilot projects on selected dams to transport sediment
past the dam and into the river reaches downstream.

2.2.5. Determine the need for fish bypass facilities.

2.2.6. Determine the impact of sturgeon commercial and sport fishing
on pallid sturgeon.

2.2.7. Determine the diagnostic characteristics to distinguish between
eggs of sturgeon and paddlefish species.

Obtain information on genetic makeup of hatchery-reared and wild
Scaphirhynchus stocks.

Determine the degree of genetic divergence between
Scaphirhynchus species within the range of pallid sturgeon.

Identify genetically meaningful management units (stocks) of
pallid sturgeon.

Determine the extent and management implications of
hybridization between Scaphirhynchus species.

2.4. I~I Obtain information on population status and trends.
