“…A fourth candidate for LP/P‐BS reproduction is Tamaulipas shiner. This species inhabits large‐stream habitats of the Rio Grande system, which supported six other cyprinid PBS species (Haworth & Bestgen, ; Platania & Altenbach, ). To our knowledge, Tamaulipas shiner previously has not been considered a LP/P‐BS candidate, but a recent phylogenetic analysis placed it in Alburnops as sister to the LP/P‐BS species, Red River shiner (Hollingsworth et al., ).…”

The emblematic minnows of the North American Great Plains: A synthesis of threats and conservation opportunities

et al. 2017

Anthropogenic changes to the Great Plains rivers of North America have had a large, negative effect on a reproductive guild of pelagic‐broadcast spawning (PBS) cyprinid fishes. The group is phylogenetically diverse, with multiple origins of the PBS mode. However, because of incomplete life‐history information, PBS designation often relies only on habitat and egg characteristics. We identified 17 known or candidate PBS fishes and systematically synthesized the literature on their biology and ecology in relation to major threats to persistence. Research output on an individual species was unrelated to conservation status, but positively correlated with breadth of distribution. The PBS species have opportunistic life‐history strategies and are typically short‐lived (generally 1–3 years) fishes. Many PBS species have truncated ranges showing declines in both distribution and abundance, especially those endemic to the Rio Grande catchment. Fundamental habitat associations are unknown for many species, particularly regarding seasonal shifts and early life stages. Critical thermal tolerances have been quantified for five PBS species and are generally >35°C. Turbidity and salinity changes are linked to responses at multiple life stages, but information is lacking on interactions between water quality and quantity. Hydrologic alteration appears to be a primary threat to PBS species, through complex interactions with landscape fragmentation, and habitat change. We highlight areas where scientific and management communities are lacking information and underline areas of potential conservation gain.

“…Daily age was estimated for age‐0 fish ( n = 34) as the number of daily rings on otoliths, assuming that increments were first deposited at hatching. The initiation of daily growth rings on otoliths at hatching has been reported in several species, including Flathead Chub Platygobio gracilis (Haworth and Bestgen ) and Smallmouth Bass Micropterus dolomieu (Hill and Bestgen ). Likewise, initiation of daily growth rings on otoliths has been observed before and after hatching.…”

Age and Growth of the Rio Grande Silvery Minnow, an Endangered, Short‐Lived Cyprinid of the North American Southwest

et al. 2018

This study provides the first comprehensive evaluation of age and age–length relationships from an extant population of the federally endangered Rio Grande Silvery Minnow Hybognathus amarus. The surveyed population was from three fragmented reaches within about 290 km of the middle Rio Grande in New Mexico, the last protected population in the historical range of the species. A total of 158 Rio Grande Silvery Minnows were collected in autumn 2009 (n = 83) and spring 2010 (n = 75), with sampling designed to fill six 10‐mm size‐class bins that represent the size range characteristic of the juvenile and adult population. Age was then determined directly for each specimen independently by two investigators, each using otoliths and scales; growth rates were estimated via back‐calculation of length at age from otoliths. The results confirm that individuals in the contemporary population are short‐lived, with very few surviving to their second or third summers. For historical comparison, the ages of a small collection of Rio Grande Silvery Minnows taken in August 1874 were evaluated using scales. The specimens in this historical collection ranged from age 0 to age 2, similar to the age range for the autumn 2009 collection and incongruent with a previously published report of five age‐classes (ages 1–5) for 13 of these specimens. Our results corroborate the age‐structure derived from temporal tracking of length frequency histograms generated under the Rio Grande Silvery Minnow Population Monitoring Project and validate current management of the species as short‐lived. Our age range and age–length relationships are also similar to those of other well‐studied Hybognathus spp., and the results from our study may aid management of these closely related, short‐lived pelagophil minnows. While additional research is needed to clarify the areas of age–length overlap, the crucial findings of this study should facilitate implementation of an appropriate management policy for this short‐lived, federally endangered cyprinid.

“…In this analysis, the CPUE for FHC of less than or equal to 6 cm total length was used to represent age-0 individuals. Age and growth analysis of FHC in FCB near site 8 found that individuals less than or equal to 6 cm total length in the fall were likely hatched that year and are of the age-0 year class (Haworth and Bestgen, 2016). These annual estimates of age-0 FHC were compared to patterns of peak flow days (in the sense of Haworth and Bestgen, 2017; see the discussion on peak streamflow).…”

By James J. Roberts, James F. Bruce, and Robert E. Zuellig AbstractThe analysis described in this report is part of a longterm project monitoring the biological communities, habitat, and water quality of the Fountain Creek Basin. Biology, habitat, and water-quality data have been collected at 10 sites since 2003. These data include annual samples of aquatic invertebrate communities, fish communities, water quality, and quantitative riverine habitat. This report examines trends in biological communities from 2003 to 2016 and explores relationships between biological communities and abiotic variables (antecedent streamflow, physical habitat, and water quality). Six biological metrics (three invertebrate and three fish) and four individual fish species were used to examine trends in these data and how streamflow, habitat, and (or) water quality may explain these trends. The analysis of 79 trends shows that the majority of significant trends decreased over the trend period. Overall, 19 trends before adjustments for streamflow in the fish (12) and invertebrate (7) metrics were all decreasing except for the metric Invertebrate Species Richness at the most upstream site in Monument Creek. Seven of these trends were explained by streamflow and four trends were revealed that were originally masked by variability in antecedent streamflow. Only two sites (Jimmy Camp Creek at Fountain, CO and Fountain Creek near Pinon, CO) had no trends in the fish or invertebrate metrics. Ten of t...
