Received: JanuAccepted: ApPublished: May 28, 2014 This effect has been attributed to variation among moon phases in lunar illumination, but our results do not support that hypothesis for angler-caught muskellunge.Ĭitation: Vinson MR, Angradi TR (2014) Muskie Lunacy: Does the Lunar Cycle Influence Angler Catch of Muskellunge ( Esox masquinongy)? PLoS ONE 9(5):Įditor: Shin Yamazaki, University of Texas Southwestern Medical Center, United States of America We argue that this variation is evidence that the effect of the lunar cycle on catch is mediated by biological factors and is not due solely to angler effort and reflects lunar synchronization in feeding. There was no difference in the lunar effect between expert and novice muskellunge anglers. The lunar effect was stronger for larger muskellunge (>102 cm) than for smaller fish, stronger in midsummer than in June or October, and stronger for fish caught at high latitudes (>48°N) than for fish caught further south. Several factors affected the amount of variation explained by the lunar cycle. We could therefore not conclude that the lunar effect on catch was due to an effect on fish behavior alone. For Lake Vermilion there was a significant effect of the lunar cycle on angler effort. We obtained angler effort data for Wisconsin, Mille Lacs (MN), and Lake Vermilion (MN). On some lakes and at night, the maximum relative effect was higher. Anglers fishing exclusively on the peak lunar day would, on average, catch 5% more muskellunge than anglers fishing on random days. The predicted maximum relative effect was ≈5% overall. At night, more muskellunge were caught around the full moon than the new moon. More muskellunge were caught around the full and new moon than at other times. Using periodic regression, we showed that the number caught was strongly related to the 29-day lunar cycle, and the effect was consistent across most fisheries. And Valentina Tereshkova was the first woman to travel into space aboard Soviet spacecraft Vostok 6." Pyle also includes profiles of more well-known figures, such as Neil Armstrong, Buzz Aldrin and Yuri Gagarin.We analyzed angling catch records for 341,959 muskellunge ( Esox masquinongy) from North America to test for a cyclic lunar influence on the catch. John Casani was a brash young engineer who took over the struggling Voyager program to reconnoiter the outer planets at a time when success was far from certain. Margaret Hamilton was an accomplished mathematician and one of the first female software engineers to design programs for spaceflight software that proved critical to the success of the moon landing. John Houbolt was an engineer who convinced NASA leadership that the most effective way to land on the moon was to use a seemingly risky technique called 'Lunar Orbit Rendezvous,' which worried NASA planners but was the only way to make the landing possible by 1969. Some examples from the promotional material: "Joe Engle was a daring test pilot who set multiple records in the dangerous X-15 rocket plane and later commanded the space shuttle three times. Space author ( and contributor) Rod Pyle profiles the pilots, scientists and engineers who worked behind the scenes to make Apollo possible, as well as the people in front of the space race spotlight.
