“…Seining of shallow, nonflowing, shorelines of off-channel habitats in the Mississippi River was effective for sampling larval and early juvenile blue suckers. Spawning occurred over a relatively short time period (10-28 days) during spring and corresponded with rising water temperatures (14-18°C) during mid-late April through early-mid May, generally corroborating information previously reported for reproductive season (Rupprecht & Jahn 1980;Moss et al 1983;McInerny & Held 1988;Burr & Mayden 1999). During sampling events at our sites, larval blue suckers were often observed in situ swimming near the surface in water less than 0.5-m deep, inaccessible to most boat-mounted sampling gear.…”

“…An appropriate water temperature regime may be more important in initiating successful spawning for a species that reportedly spawns in channel currents rather than on the floodplain (Moss et al 1983). Steadily rising main channel water temperatures within the appropriate range for spawning were available during spring of both years.…”

“…Spawning has never been observed directly, but Moss et al (1983) captured adults readily extruding gametes during handling from a deep (1.4 m), fast-flowing (1.8 mAEs )1 ) cobble riffle in the Neosho River, Kansas, USA; this represents the only observation to date on probable spawning habitat. Existing knowledge of the reproductive ecology of blue suckers is largely inferred from the capture of adults, because young life stages have been underrepresented in previous life history studies (e.g., Rupprecht & Jahn 1980;Moss et al 1983).…”

Ecology of larval blue sucker, Cycleptus elongatus, a North American catostomid that has declined throughout its range, is poorly known because larvae have rarely been sampled. A total of 316 young blue suckers (16.0-39.0 mm total length) was captured over 3 years at 14 offchannel sites in Pool 25, Mississippi River. Blue suckers demonstrated distinct temporal and spatial abundance patterns. Blue suckers were only captured in late May/early June, and were more abundant during a year of little flooding. Abundance was correlated with the distance a site was from the main channel, being highest in island borders and island sloughs in proximity to the channel. Fish guts contained a relatively high biomass of chironomids and zooplankton, suggesting islands were providing suitable feeding opportunities. Because of their proximity to flows, slack waters provided by islands were accessible to blue sucker larvae dispersing from channel spawning areas and facilitated their development into rheophilic juveniles.

“…Common foods of blue sucker include midge and caddisfly larvae as well as algae (Sublette et al, 1990;Walburg et al, 1971). The age at sexual maturity for blue suckers is approximately 3-years old; females mature faster than males and exhibit larger sizes (Moss et al, 1983). Generation times are roughly 10 years (Bessert & Ortí, 2008).…”

“…Generation times are roughly 10 years (Bessert & Ortí, 2008). C. elongatus is a nonguarding annual spring spawner (April-June) that can migrate hundreds of kilometers upstream to deposit young in deep riffles that have coarse substrate (Moss et al, 1983;Mettee & Shepard, 1997). In the middle Missouri River, blue suckers rely heavily on different habitat types between spring and summer (Neely et al, 2010).…”

Archaeological data suggest broader early historic distribution for blue sucker (Cycleptus elongatus, Actinopterygii, Catostomidae) in New Mexico

2016

Zooarchaeological data are increasingly important for establishing late Holocene conservation baselines for species of concern. The blue sucker (Cycleptus elongatus) is experiencing range reduction and is endangered in the State of New Mexico. The early historic (ca. AD 1540) distribution of blue sucker is poorly understood, and the extent of habitat loss is unclear. In 1961, two blue sucker skeletal elements were recovered from a late prehistoric/early historic archaeological site in northern New Mexico called Rainbow House (LA 217). Those remains suggest that the past range of blue sucker was larger; however, since that publication, little consideration has been given to the past presence of this species in the Upper Rio Grande. New zooarchaeological data from a site in northern New Mexico called Ponsipa (LA 297) have revealed the presence of multiple blue sucker skeletal elements. Additionally, a review of site reports and regional archaeological journal publications increased the abundance of blue sucker elements found at Rainbow House and added three archaeological sites where blue sucker has been reported in the region. Collectively, this information suggests a broader preimpoundment distribution for blue sucker than previously recognized and can help establish a new baseline for their conservation or restoration in New Mexico.

Blue sucker (Cycleptus elongatus) populations occur in the Mississippi River and Gulf of Mexico drainages of North America and are negatively affected by habitat fragmentation and flow regime alteration caused by dams. During fish assemblage surveys in August of 2022, we collected five juvenile blue suckers (312–428 mm total length) in the Angelina River upstream of Sam Rayburn Reservoir in East Texas (46,335 ha surface area) where the occurrence of the species was previously unconfirmed. Given this unexpected finding, we (1) analyzed mesohabitat associations to compare habitats we sampled with reports in the literature and (2) reviewed blue sucker occurrences in state, national, and global databases across historical (1950–1980) and contemporary (1981–2022) time periods to assess occurrence across gradients of habitat fragmentation and streamflow regulation. The blue sucker population in the Angelina River upstream of Sam Rayburn Reservoir was previously unconfirmed but is within the native range. Mesohabitats occupied by blue suckers were consistent with literature reports, including fast velocity, shallow depth, and coarse substrates. The low degree of regulation (19% of natural runoff stored by upstream reservoirs) and a high degree of habitat connectivity (287 rkm of unfragmented mainstem habitat) for the Angelina River upstream of Sam Rayburn Reservoir matched range‐wide patterns of persistence within relatively intact (unfragmented and unregulated) or remnant (fragmented but unregulated) riverscapes. Our review reveals that blue sucker populations might persist (1) in remnant river fragments where local habitat conditions are appropriate and (2) where effects of habitat fragmentation and flow regulation are not coupled.
