LAFITTE, La. — The dock at Bundy’s Seafood is quiet, the trucks are empty and a crew a fraction of the normal size sits around a table waiting for something to do. But the most telling indicator that something is wrong is the smell. It smells perfectly fine.
“There’s no shrimp,” explained Grant Bundy, 38. The dock should smell like a place where 10,000 pounds of shrimp a day are bought off the boats. Not this year. In all of September, Bundy’s Seafood bought around 41,000 pounds.
White shrimp season began in late August, and two months in, the shrimpers here say it is a bad one, if not the worst in memory. It is bad not just in spots but all over southeastern Louisiana, said Jules Nunez, 78, calling it the worst season he had seen since he began shrimping in 1950. Some fishermen said their catches were off by 80 percent or more.
“A lot of people say it’s this, it’s that, it’s too hot, it’s too cold, it’s BP,” Mr. Nunez said. “We just don’t know.”
There is plenty that is not known. Louisiana’s Department of Wildlife and Fisheries has not compiled landings data for the season, so at this point it is hard to measure with any certainty the degree to which it is abnormal.
Even if the reports of a dismal season prove true, any forensic work is complicated by the oddities of this year’s weather, with a severe drought in the states along the Gulf of Mexico interrupted by spring flooding on the Mississippi River that brought millions of gallons of fresh water into the marshes. In addition, white shrimp crops have fluctuated over the decades for various reasons. (A BP spokesman said in a statement that some preliminary sampling indicated that the 2011 white shrimp population was within the historical range of variability.)
“We’re going to have to look at all of those different things and come up with reasons why it’s down, if it is down,” said Jim Nance, a shrimp biologist at the National Marine Fisheries Service.
But while all scientists acknowledge the difficulty of determining a cause for a reported decline in the shrimp crops, some say there is evidence that is at the very least suggestive of a culprit.
Joris L. van der Ham, a researcher at Louisiana State University who has been studying white shrimp, said he had found more white shrimp than usual last winter in estuaries that were affected by the BP oil spill. That abundance might have been due in part, he said, to a decrease in the number of people out shrimping last year, but a significant decline in this year’s season would undercut that assumption.
While cautioning that his study is incomplete, Dr. van der Ham speculated that certain compounds in the oil may have stunted the shrimp’s growth rate, and that the large numbers he found last year might have never made it out into the gulf to spawn, thus explaining a missing generation.
“There are numerous lines of evidence now that are sort of lining up that chronic exposure to this material could be problematic,” said James Cowan, a professor in L.S.U.’s department of oceanography and coastal sciences.
Those who work in the gulf seafood industry, as well as their lawyers, have watched closely for signs of a species collapse similar to the one that decimated the herring fishery four years after the 1989 Exxon Valdez spill in Alaska. The causes of even that collapse remain a matter of dispute, but it is often cited as an example of the delayed disaster that shrimpers and others fear.
This concern was stoked further by a recent study by L.S.U. researchers that reported that a species of fish abundant in Gulf marshes was showing signs of cellular damage, problems typically due to exposure to oil. The functions of the fish, a minnow called the killifish, have been affected in ways that could harm reproduction, the study found.
Seafood industry representatives say there is enough uncertainty to raise doubts that the shrimp harvest will recover by 2012, a supposition in a report that Kenneth R. Feinberg, the administrator of the $20 billion compensation fund for victims of the spill, used in his formula for determining final settlements.
Mr. Feinberg, in an interview, pointed out that he had, all along, described his report as preliminary and open to revision depending on new findings.
“We are monitoring this, and we are sensitive to these concerns,” he said. “We reserve the right to change the formula if anecdotal and empirical evidence justifies it.”
Concerns about the lack of shrimp are different from concerns about the state of shrimp that are found. Repeated studies have shown gulf seafood is safe to eat, a fact trumpeted by industry representatives and government officials, who launched a gulf seafood safety Web site last week to reassure consumers.
All of this demonstrates just how hard it has become to make a living on shrimp boats, said David Veal, the executive director of the American Shrimp Processors Association.
Mr. Veal has heard the anxieties about the white shrimp season, but while “clearly something is going on,” it is too early to say whether it is the worst in memory, he said.
Whether it is the worst or just very bad is almost immaterial, Mr. Veal said; it is still another blight on the shrimping life, compounded by the decline in the domestic market, the steep rise in fuel prices and the battery of hurricanes over the last decade.
“The fact that anybody is still in this business is a testament to their tenacity,” he said.
