Salmon (image) University of California - Davis Caption In winter 2013, a UC Davis-affiliated experiment in rearing salmon on the farmed Yolo Bypass floodway near Sacramento produced remarkable results. In 40 days, juvenile Chinook salmon grew nearly 1.5 inches longer and packed on weight at an average rate of 0.17 grams a day (pictured). Juvenile salmon that started at the same size and were released into the Sacramento River at the same time grew only about half as fast (not pictured).
