Blue sucker, Cycleptus elongatus (Le Sueur), was sampled in the Kansas River, Kansas, USA to determine how relative abundance varies spatially and growth compares to other populations. Electric fishing was conducted at 36 fixed sites during five time periods from March 2005 to January 2006 to determine seasonal distribution. An additional 302 sites were sampled in summer 2005 to determine distribution throughout the river. A total of 101 blue sucker was collected ranging from 242 to 782 mm total length and 1-16 years old. Higher catch rates were observed in upper river segments and below a low-head dam in lower river segments, and catch rates were higher during November in the upriver sites. Kansas River blue sucker exhibited slower growth rates than other populations in the Great Plains including populations as far north as South Dakota.

“…The blue sucker, Cycleptus elongatus (Lesueur), is found throughout the Mississippi, Missouri and Ohio river drainages from Montana to Mexico and east to Pennsylvania (Moss, Scanlan & Anderson 1983; Hand & Jackson 2003; Morey & Berry 2003). This obligate, large‐river species typically inhabits riffle and run habitats associated with sand, gravel and cobble substrates for spawning and feeding (Moss et al.…”

Blue sucker represent a significant component of large river ecosystems, historically supporting substantial commercial fisheries in the Mississippi River drainage with catches exceeding 1 million kg in the late 1800s (Coker 1929; Morey & Berry 2003).…”

“…Population abundance of blue sucker has likely declined throughout its native range as a result of anthropogenic influences including channelisation, dams and overharvest (e.g. Hand & Jackson 2003). As a result, the blue sucker is a species of special concern throughout much of its current distribution (Elstad & Werdon 1993; Hand & Jackson 2003).…”

Blue sucker, Cycleptus elongatus (Lesueur), populations have declined because of habitat degradation and overharvest, and little information exists on the population characteristics and stock dynamics of this species. We examined size and age structure, mortality, growth and condition of blue sucker in the Wabash River, Indiana-Illinois, USA. A total of 356 fish collected by electric fishing from June 2003 to April 2006 ranged from 238 to 775 mm total length and 85 to 5288 g wet weight. Age ranged from 3 to 16 years and annual mortality ranged from 22 to 25%. Annual growth was greatest among younger age classes (range 48-141 mm yr )1 ) and declined after age 6, likely at the onset of reproductive maturity. Variation in the relative condition factor (range 66-141) was heteroscedastic over the size range of fish sampled, perhaps attributable to seasonal differences in reproductive condition among mature fish.

Comparison of Four Hard Structures Including Otoliths for Estimating Age in Blue Suckers

et al. 2021

The Blue Sucker Cycleptus elongatus is an imperiled North American catostomid in need of management and protection. No hard structures are validated for aging this species, but past studies focused on somatic structures such as fin rays and scales. Calculated parameters (mortality, recruitment, growth) that inform management decisions are directly influenced by the accuracy and precision of the hard structure used to estimate age. We identify the most precise and credible structure with which to age Blue Suckers while also completing the first in-depth investigation of their otoliths. We collected Blue Suckers (n = 168) from the lower Wabash River and compared ages estimated from scales, opercles, pectoral fin rays, and lapillus otoliths but were unsuccessful in estimating ages from cleithra. We identified structure bias between all structures and found scales (n = 67; maximum = 11 years, mean = 8.2 years) and opercles (n = 65; maximum = 15 years, mean = 8.3 years) to be substantially less precise than pectoral fin rays and lapillus otoliths. We found that otoliths (n = 128; maximum = 42 years, mean = 13.5 years) were more precise than fin rays (n = 167; maximum = 20 years, mean = 9.6 years) and yielded a much higher range of ages. We could not identify any range of ages or total lengths in which (nonlethal) fin ray age could be accurately corrected to (lethal) otolith age. Thin-sectioned otoliths are the gold standard for aging most fishes, including numerous age-validated catostomids, and the credibility of Blue Sucker otolith age estimates was additionally supported by a strong correlation between whole lapillus mass and estimated age (R 2 = 0.89). Overall, evidence indicates that Blue Sucker lapillus otoliths yield more precise and credible age estimates than other hard structures.
