Standard-length coded wire tags (1 mm long x 0.25 mm in diameter) were injected into the cheek musculature of 240 fingerling (47-128-mm-long) largemouth bass Micropterus salmoides. After 9 weeks, tags remained in all of the 200 surviving fish as well as in all 19 of the dead fish examined. Histological analysis indicated that the tissue surrounding the tags was healed. Cheek tagging with coded wire tags appears to have considerable potential for permanently identifying specific groups of largemouth bass. Although the originators of the coded wire identification system (Jefferts et al. 1963) foresaw its potential for use with various macroorganisms, its major use has been for permanently tagging salmonids and particularly Pacific salmon (Oncorhynchus spp.). It has become the standard method for evaluating production on the Pacific coast of North America where 126 million anadromous salmonid fish were marked with coded wire tags from 1981 through 1984 (Johnson 1985). The tagging methods described by Bergman et al. (1968), Ambrogetti (1976), Koerner (1977), and Duke (1980), which involve injecting tags into the snouts of juvenile fish, are those generally practiced on the Pacific coast. In salmonid fishes, the midline snout cartilage has been the designated target for coded wire tagging, but, as Zajac (1985) pointed out, tags may be more frequently recovered from fibrous, muscle, and adipose tissue between the olfactory bulbs. . 1968.

Returning surplus adult coho salmon (Oncorhynchus kisutch), principally sexually precocious males (jacks), were confined in 1,500 ft of stream adjacent to the Washougal River salmon hatchery near Camas, Washington. To increase the benefits from hatchery production, the Washington Department of Fisheries then opened the area to free fishing. Regulations restricted fishing gear to rod, hook and line, and made retention of all salmon caught mandatory regardless of whether they were hooked inside the mouth or outside the mouth (snagged). Catch and fishing effort estimates were obtained from interviews, automobile counts and streambank sampling. Economic data and the opinions of fishermen and observers regarding the fishery were also obtained from interviews. During the 41‐day season extending from September 21 through October 31, 1967, 14,689 fishermen trips resulted in a catch of 22,749 jacks and 9,552 3‐year‐old coho salmon weighing a total of 136,883 lb. Most of these fish were snagged. The net economic value of this recreational fishery was estimated to be substantially more than the net value that would have resulted from the alternative of selling the fish to a commercial buyer. Participating fishermen and observers were largely in favor of the special fishery.
