Numbers above bars indicate each strain's percentage contribution (rounded to the nearest tenth of a percent) to total rainbow trout produc- tion. The general purpose strains are "domestic", maintained entirely within hatch- ery waters and selected for higher production and greater ease of handling. Most of these are now under a sophisticated selection program described by Gall (1979). In contrast, two of the special purpose strains, ELT and RTKJ, are "wild"; they are maintained in lakes but spawned by hatchery personnel and reared to some extent in hatcheries before being returned to the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original California.
