American officials have suspended all fishing in parts of the Gulf of Mexico tor at least 10 days because of the huge oil spill.(26)The restrictions will give scientists time to study the effects on seafood in the gulf. Sunday’s order extended from the mouth of the Mississippi River in Louisiana east to waters of Pensacola Bay in Florida. The affected waters include areas off the coasts of Mississippi and Alabama.(27)On April 20 an oil drilling machine exploded and sank about 80 kilometers from the Louisiana coast. Eighty percent of the seafood eaten by Americans is imported.(28)But the fishing industry in Louisiana is responsible for about 1/3 of all seafood caught in the United States. Seafood is worth nearly $2.5 billion to the state. The spill comes shortly before the start of the fishing season. The fishing ban announced on Sunday did not affect state waters west of the Mississippi River. Those waters represent 77% of Louisiana’s total seafood production. Another important industry along the gulf is tourism. Coastal communities have been waiting and watching for days for oil to arrive on their shores.(29)Bad weather has interfered with efforts to send out boats to clean up the oil and watch for the effects on wildlife in the Gulf of Mexico. Bird populations are among those at risk of being poisoned by the oil. Bird rescue groups have set up stations. But they say finding injured birds in the huge spill and sending out boats to rescue them will be a difficult job.
