Abstract
Length-weight relationships provide foundational knowledge for managing fisheries populations. However, there are many species where the length-weight relationships are not widely understood. The Flier (Centrarchus macropterus) is one species where there is a lack of information regarding its length-weight relationship and spatial variation associated with this relationship. A new study was needed to assess the length-weight relationship for this species. Fliers were collected from upper Moro Creek during October 2023. Multiple gears (backpack electrofishing and seining) were employed to increase detection of this species. Length (mm), and weight (g) were recorded for every individual observed. A total of 85 Flier were sampled from four sites in the upper Moro Creek watershed, and their average (±SE) length was 75.7 (±1.8) mm and average weight was 8.5 (±0.7). The length-weight for Flier in upper Moro Creek was Log(W) =-4.2 + 2.7Log(L). Mean (±SE) Fulton’s condition factor (K) was 1.7 (±0.1), mean LeCren’s relative condition factor (Kn) was 1.0 (±0.1) and mean relative weight (Wr) was 100.5 (2.9). Our estimates of condition on this species are similar to other estimates of condition for this species in other water bodies. However, it is apparent that our data displays some sampling bias to older (larger) individuals in this population, which may have influenced our ability to accurately estimate the length-weight relationship of this species. This research provides a foundation of knowledge on the length-weight relationship of Fliers in predominantly lotic ecosystem in Arkansas.
