In May, Harriet M. Perry, the director of the fisheries program at the Gulf Coast Research Laboratory, was asked to examine some mysterious droplets found on blue crab larvae by scientists at Tulane University. An early test indicated that the droplets were oil, and she has continued to find similar droplets on fresh larvae samples taken all along the northern Gulf of Mexico.

Despite the potential significance of the discovery, Dr. Perry does not have research money to cover further tests. And like other scientists across the Gulf Coast who are racing to sketch out the contours of the BP oil spill’s effects, she has few places to turn for help.

The only federal agency to distribute any significant grant money for oil spill research, the National Science Foundation, is out of money until the next fiscal year begins Oct. 1. The Environmental Protection Agency, which has only $2 million to give out, is still gearing up its program. A $500 million initiative for independent research promised by BP, which was to be awarded by an international panel of scientists, has become mired in a political fight over control. State agencies, too, are stymied.

“We have met with every possible person we can regarding this issue, built the templates, sent in the requests, and we are waiting to see,” said Hank M. Bounds, the Mississippi commissioner of higher education, speaking of the needs of Ms. Perry and other scientists.
