DNR fish survey, 2021

Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.

Spring Trap netting was performed May 24-26 to provide pre-regulation data on the Bluegill size structure. A bag limit of 5 sunfish was implemented on March 1, 2021 as Long Lake was selected for participation in the statewide Quality Sunfish Initiative. The objective of the lowered bag limit is to reduce sunfish harvest and allow for more fish to attain larger sizes (8-10 inches). Information collected during this survey is considered pre-regulation data due to the short time period since the inception of the reduced bag limit. Spring trap netting is the preferred method for evaluating panfish populations and has been conducted on the lake four previous times since 2003. Several future evaluations relating to the 5 sunfish bag limit are planned over the 10 year evaluation period and will incorporate spring trap netting to provide proper comparisons. Spring trap netting in 2021 captured 274 Bluegill. Sample sizes for Bluegill in Long Lake have ranged from 216 to 604 fish over the five historical efforts. Bluegill in 2021 ranged from 3.3 - 9.1 inches and mean length was 6.77 inches. Many of the fish were of sizes desired by anglers, as Bluegill over 7 inches comprised 51% of the catch and fish greater than 8 inches made up 13% of the sample. Only two fish over 9 inches were measured. Bluegill 10 inches or greater have not been observed in any spring trap net efforts. Prior to 2016 Bluegill over 8 inches comprised from 1-5% of the catches and fish 9 inches or longer were absent. Bluegill size structure goals developed for the Quality Sunfish Initiative aim for at least 50% of the sample to exceed 7 inches, 20% to exceed 8 inches and 3% over 9 inches. Whether voluntary or required due to the reduced bag limit, release of larger sunfish, especially fish over 9 inches will be important if the lake is to realize its potential in reaching management goals. Additional criteria that may be used to measure success of the reduced sunfish bag limit include: mean size, catch rate of fish over 8 inches, and mean length of top 10% of fish. When combining the five pre-regulation spring trap net surveys mean size is 5.98 inches, mean catch rate of fish over 8 inches is 1.8/net, and mean length of the top 10% is 7.90 inches. Aging conducted in 2020 showed that Bluegill displayed good growth, reaching 7 inches at Age 5. Spring trap nets have produced Black Crappie catches that have ranged from 18 to 112 fish since this type of sampling began in 2003. The 2021 effort provided a sample of 50 fish ranging from 3.1 to 13.4 inches in length. Fish 10 inches or longer comprised…
