I had the front endplate on the cooling water side of the surface condenser (called the channel head cover) removed. Most of the tube inlets in the channel head tubesheet were plugged with crayfish (but in Louisiana where this story is set everyone calls these little creatures, crawfish). 

Crayfish and crabs are two important crustacean seafoods in Louisiana, one of the most important seafood-producing states. Crayfish are about the size of a shrimp and look like small lobsters. Crayfish, also known as "crawfish" in Louisiana, have been regarded as one of the most important elements in Cajun cuisine, which is famous for its unique flavors. 

The red swamp crayfish is the major ccnmercial species. While the tail meat has been the major edible portion of crayfish, its hepatopancreas, also known as crawfish "fat" in Louisiana, is traditionally considered a rich source of natural crayfish flavors. Kinlin et al. (2) used steam distillation as a method of isolation and analyzed the volatile components of hepatopancreas from a boiled crayfish sample after the sample had been stored frozen for 3-4 months. Information on the flavor components in freshly boiled crayfish is needed for crayfish product quality improvement. 

This area of Louisiana is one of the most productive estuaries in the continental United States in the commercial production of shrimps, menhaden (fish), oysters, crayfish (also known as crawfish and crawdads), crab, mussels, and other marine species. Louisiana is also known as a sportsman s paradise because of the recreational fishing, as well as significant commercial fishing. For example, the shrimp industry is worth over US 350 million per year in Louisiana.
