Back in the late 80's I bought a block of "Rod and Reel" brand frozen shrimp. To thaw it I threw the block in the livewell. After thawing, several shrimp were scattered throughout the livewell. I "thought" I got them all out. A few days later we noticed a horrible stench coming from near the boat. I looked in the livewell and literally dry heaved. One had lodged under the drain tube. Hard to believe a single shrimp stunk so bad my neighbors noticed it. Lesson learned...
