History & Status of the Fishery
Walleye were sampled with gill nets at a rate within the lake class expected range, but it was the second lowest catch rate since 1967. The fish sampled were a good size, averaging 4.1 pounds, but it appears that there was limited recruitment and no fish were sampled below 17.3 inches. The average length was 22.2 inches and the longest was 27.6 inches. Ruby has been part of a statewide research project evaluating different stocking strategies. As part of this project, Ruby has been stocked with oxytetracycline (OTC) marked fry in 2001 and 2003, and OTC marked fingerlings in 2005. Only two fish were sampled that were aged to an OTC marked stocking year (2001). One fish was marked representing a stocked fish and the other was not (natural reproduction).
Northern pike were sampled at a rate within the lake class expected range, similar to the 2001 assessment but below the highest rate in the 2004 special assessment. The longest northern pike sampled was 33.5 inches, and the average length was 23.4 inches. The size structure was good with 17% of the fish sampled over 29 inches. The growth rate was above the state average for ages one, two and five, and similar to the state average for the rest.
Largemouth bass were sampled in gill nets at an expected rate for the lake class, while smallmouth bass, sampled in gill nets, were above the lake class expected range. Both species were also sampled with electrofishing at a moderate rate, but because of changes in the survey stations no real relationship to the previous assessment can be made. The electrofishing stations used for the bass population assessment were run concurrent with the six stations used for the walleye research project. The size structure appears to be moderate and growth rates were below or near the state average for both species.
Bluegill were sampled in trap nets at a rate above the expected lake class range, similar to the previous assessment. Historically, the abundance has been lower. The size structure was poor with an average length of 5.2 inches and no fish sampled over eight inches.
Yellow perch were sampled within the lake class expected range, and slightly lower than the previous assessment. Only one tullibee was sampled in 2006, the lowest recorded catch rate. Both species have had fluctuating populations and have been historically sampled at lower densities. Other species sampled include; black crappie, pumpkinseed, rock bass, and white sucker.
