WebIn animal husbandry, feed conversion ratio (FCR) or feed conversion rate is a ratio or rate measuring of the efficiency with which the bodies of livestock convert animal feed into the desired output. For dairy cows, for example, the output is milk, whereas in animals raised for meat (such as beef cows, pigs, chickens, and fish) the output is the flesh, that is, the body … WebDec 14, 2024 · Overview. NOAA Fisheries scientists study different aspects of a fish's life and development, including growth, maturity, and natural mortality. Scientists specifically assess the age and growth rates of fish species by studying fish ear stones, called otoliths. Otoliths reveal the ages of individual fish, almost like counting the rings in a tree.
