Factors Influencing Fish Species Distribution in Lake St. George

This discussion explores why certain fish species, such as the Pumpkin Seed, may not be present in Lake St. George despite the diverse aquatic habitat. Various factors like water depth, temperature, oxygen concentration, and the presence of prey can influence fish populations. Shallow areas might have higher oxygen levels, affecting species preferences, while the time of day and year also play crucial roles in fish behavior and availability. Understanding these dynamics is essential for effective fishing and conservation efforts in the lake.

  2. Question 4Why do you think there are species of fish in lake St George that did not appear in our catch? The temperature wasn’t right because the depth of the lake didn’t stretch deep enough for certain species. Maybe some fish need less oxygen concentration, and the shallowness puts a lot of oxygen. Some species are small enough to slip through the net. Some species’ prey are in deeper area, so predator wouldn’t be there. Time of the day (sunlight breech) Time of the year Water push Interference Fishes prefer different environment Fish move around Plant impact Fished in different spot -fish live in various depths and regions
