Length-Weight Relationships of Fall Chinook Salmon (Oncorhynchus Tshawytscha) Corresponding to Differential Densities
Miner, Paul A.
The purpose of this study was to determine whether reductions in standard rearing densities, of fall chinook salmon (Oncorhynchus tshawtscha) fingerlings, would result in elevated growth rates. Length-weight data was collected to yield growth rates expressed in grams of fish biomass per fish, and a condition, or K, factor. Growth rates, however did not increase as rearing density decreased. Therefore, the treatments applied in this study were determined to be outside the range of affects on the growth rates. Although no significant differences in growth rates were found in this study by decreasing the standard rearing density, future studies that compare growth rates, as the standard rearing density increased, may encourage fish hatcheries to increase the rearing density of chinook salmon in rectangular flow through tanks.
