Winter Survival Strategies Of Benthic Invertebrates In Temporary Habitats In A Northern Minnesota Lake, Cal Oldenburg
Winter Survival Strategies Of Benthic Invertebrates In Temporary Habitats In A Northern Minnesota Lake, Cal Oldenburg
Journal of Earth and Life Science
During the winter months in the northern hemisphere, above 40 degrees latitude, a freezing event occurs that can last several months. Some lakes may have large portions of the shallow littoral zone frozen completely solid down into the sediments. Invertebrates affected by these events have developed survival strategies to cope with the harsh environment. The two main strategies for invertebrates in these areas are to either migrate to a different area and recolonize the original area when it becomes available again, or to burrow into the sediments and withstand the freezing. A 1- month study took place on Lake Bemidji …
White Bass Assessment In Regards To Changes In Water Level On Lake Traverse, Aaron Wilson
White Bass Assessment In Regards To Changes In Water Level On Lake Traverse, Aaron Wilson
Journal of Earth and Life Science
Until recently the white bass Morone chrysops has been somewhat ignored by anglers, more so in Minnesota than other states; most likely due to their limited distribution throughout the state. However, with more anglers becoming aware of the sporting and culinary potentials of white bass, interests have risen. With this rise in angler interest, there should be a rise in white bass assessments. Knowing what factors may be influencing white bass population dynamics will allow fisheries professionals to better manage and protect white bass fisheries. White bass are often found in rivers and impoundments were dams are present and water …
Brown Trout Spawning Location And Relationship To Suitable Winter Habitat, Matthew L. Skoog
Brown Trout Spawning Location And Relationship To Suitable Winter Habitat, Matthew L. Skoog
Journal of Earth and Life Science
Brown trout are a popular game fish throughout much of the world. Understanding habitat requirements is necessary for the successful management of brown trout. This study looks at the spawning habitat preferences and relationship of redd location to wintering habitat of brown trout in the Straight River, Minnesota. Brown trout in the Straight River were found to spawn in similar habitat to brown trout looked at in previous literature. All redds were located on gravel substrate. Seventy eight percent of redds were associated with some sort of cover. Water velocities at the redd sites. (mean=0.456 ms/cm), dissolved oxygen (mean=9.78 mg/L), …
Comparison Of A Length Size Limit Of Northern Pike Population On Two Lakes In North Central Minnesota, Ethan A. Puttonen
Comparison Of A Length Size Limit Of Northern Pike Population On Two Lakes In North Central Minnesota, Ethan A. Puttonen
Journal of Earth and Life Science
Fisheries managers use length size limits on northern pike (Esox lucis) to improve the size structure in select lakes. The objective of this study was to compare two similar lakes, one with a length size limit and one without, to determine if a length size limit is improving the northern pike size structure. Blueberry Lake showed a higher abundance of larger fish than Stocking Lake. Of the fish caught, 25% in Blueberry Lake were over 600 mm (24 in), and were in the protected slot. Stocking Lake had a smaller portion of fish of this size with only …
