Fall 2012 Fyke Net Assessment – A general survey was conducted on Five Island Lake to collect fish for RAFT (Region Ambient Fish Tissue) monitoring program and to assess the adult and subadult fish populations of Five Island Lake.
Low numbers (26) of walleye were sampled during the 2012 fall fyke net assessment which was inadequate to properly assess the walleye population of Five Island Lake; therefore, a general assessment will be made. A catch rate of 1fish per net was below the lakes median value of 3 fish per net, (2 – 4 fish per net, lower and upper percentiles) reflecting a lower than typical walleye catch. Results of the 2012 fall fyke net assessment reflects a walleye sample well represented by angler acceptable size and larger fish in the overall walleye catch. Quality (15.0 – 19.9 inches) and preferred (> 20.0 inches) sized walleye comprised 46 percent (35 and 11 percent, respectively) of the total walleye sample, suggesting good size structure of these groups in Five Island Lake. Stock (10.0 – 14.9 inches) size fish comprised the remaining 54 percent of the sample, indicating good presence of small fish in the catch, which will recruit to the fishery in the next few years. A walleye relative weight of 87 is below the target range of 95 – 105 indicating an overall body condition in less than desired state.
White and black crappie were detected in excellent numbers during the 2012 fall fyke net assessment. White and black crappie catch rates were also comparable to typical catch rates from other crappie lakes within the Spirit Lake District, suggesting a strong presence of this species within Five Island Lake. A white crappie catch rate of 17 fish per net was approximately 4 times higher than the lakes median value of 4 fish per net and the highest catch rate recorded since the 2000 fall fyke net assessment (11 fish per haul), suggesting excellent numbers white crappie exist in Five Island Lake. Length frequency analysis indicates a fish population dominated by good numbers of angler acceptable size fish and larger that will be attractive to the serious crappie angler at Five Island Lake. A PSD value of 55 suggests a population comprised of quality (8.0 – 9.9 inches) and preferred (> 10.0 inches) size fish in good numbers (43 and 12 percent, respectively). Stock (5.0 – 7.9 inches) size fish, representing the remaining 45 percent of the total white crappie catch were also sampled in good numbers. This year class will sustain the fishery as these fish will recruit to the fishery in the next few years. Relative weight (WR), an index of body condition, was 90 which are slightly below the target range of 95 – 105, indicating a white crappie population in fairly good body condition.
A black crappie catch rate of 9 fish per net during the 2012 fall fyke net assessment was significantly greater than the lakes median value of 2 fish per net (1 – 5 fish per net, lower and upper percentiles) and is the largest catch rate since 2001 (17 fish per net) suggesting an excellent black crappie population in Five Island Lake. Length frequency and RSD values indicate good size structure of the black crappie population of Five Island Lake. Quality (8.0 – 9.9 inches) and preferred (> 10.0 inches) size fish comprised 38 percent of the total black crappie catch indicating good numbers of this size group in Five Island Lake. Stock (5.0 – 7.9 inches) size fish comprised the remaining 62 percent of the total black crappie catch which will provide adequate recruitment and sustain the black crappie fishery for the next few years. Relative weight (WR), an index of body condition, reflexes a black crappie population in excellent body condition. A relative weight of 106 is slightly above the target range of 95 – 105 indicating a fish population in very plump condition.
Bluegills were also sampled in excellent numbers during the 2012 fall fyke net assessment. A bluegill catch rate of 4 fish per net was higher, but comparable to the lakes median value of 2 fish per net (0 – 4 fish per net, lower and upper percentiles) suggesting a higher, but more typical fish population of Five Island Lake. PSD (proportional stock density) of 65 indicates a fish population comprised of large fish which should be attractive to the serious bluegill angler. Quality (5.0 – 7.9 inches) and preferred (> 8.0 inches) size fish comprised 64 and 1 percent respectively with stock (3.0 – 5.9 inches) size fish making up the remaining 32 percent of the total bluegill catch. A relative weight of 115 is above the target range of 95 – 105 indicating fish in excellent body condition.
Channel catfish continue to be sampled in strong numbers during the 2012 fyke net assessment. Since 1999, channel catfish have been stocked into Five Island Lake; therefore, it is assumed that these fish present in the catch were the result of those stockings. A catch rate of 24 fish per net increased (6 fish per net, 2007 fall fyke net assessment) and is the highest catch recorded since fall fyke net assessment began in 1986. Channel catfish population assessment was made from the summer 2011 tandem hoop net assessment therefore; interpretation of the channel catfish population of Five Island Lake will not be made from the 2012 fall fyke net assessment.
For the fourth consecutive year bullheads was detected in low numbers during the 2012 fall fyke net assessment. Bullhead catch rates have ranged from a high of 3 fish per net (2001 fall fyke net assessment) to a low of less than one fish per net (2007 fall fyke net assessment) suggesting for the past 11 years a very limited bullhead population in Five Island Lake.
Northern pike (n = 1), yellow perch (n = 28) and largemouth bass (n =1) were also sampled in limited numbers during the 2012 fyke net assessment.
Rough fish comprised of carp and buffalo were also sampled in trace numbers.

Iowa-Caught Fish Are Safe to Eat, In Almost All Cases
The vast majority of Iowa’s streams, rivers and lakes offer safe and high-quality fish that pose little or no threat to human health if consumed. Some limitations may apply for young children and pregnant women. Here’s a Fish Consumption Fact Sheet from the Iowa DNR and the Iowa Dept. of Public Health for more information. Here is a list of current fish consumption advisories for Iowa lakes and rivers.
