Common logperch

[7] While the common logperch is not currently listed as a threatened or endangered species, humans should be aware of our negative impact on the species, and the ways in which we can minimize this impact; most notably, by limiting the construction of dams, by increasing oxygen levels in the tailwaters of existing dams, by limiting the number of predatory gamefish stocked (such as saugeye), by decreasing the amount of silt and debris deposited in streams, and by monitoring nitrite levels in common logperch habitats.

Also, a monitoring plan should be created, in which a routine census is taken of the fish in each area of its distribution, and in which invasive species that outcompete the common logperch, such as Neogobius melanostomus, are removed.

Westwards, logperch are most heavily distributed in the Mississippi River drainage system, and their range extends eastward in freshwater habitats all the way to the Atlantic Ocean.

It is an invasive species, Neogobius melanostomus (round goby), however, that poses the largest competitive threat to the common logperch.

[9] Natural predators of the common logperch consist most notably of carnivorous piscivores from the Sander, Micropterus, and Esox genera.

The common logperch spawns numerous times in the warmer months of the year, typically during spring and summer.

Thus, the common logperch has maintained its ancestral reproductive tendencies, and therefore has not evolved any new adaptations in comparison to other darter species.

[12] Some human-induced changes with negative effects on the life history of the common logperch include the construction of dams and erosion around water drainages.

[12] Large amounts of silt created by the constant change of water flow by dams for hydroelectric generation is also detrimental to logperch species.

The overuse of pesticides and fertilizers near watersheds can also have a deleterious effect on the common logperch by killing or altering aquatic insect life, and by increasing nitrite levels.

The common logperch was first formally described as Sciaena caprodes in 1818 by the French polymath Constantine Samuel Rafinesque (1783–1840) with the type locality given as the Ohio River.
