Available in PDF, EPUB and Kindle. Book excerpt: Geomorphic changes resulting from the construction of dams, irrigation diversion structures, and flood control levees has separated the Rio Grande from its floodplain contributing to the decline of native fish species including the endangered Rio Grande silvery minnow (Hybognathus amarus). The species is currently restricted to 280‐km of the river in New Mexico. Since 2006, the New Mexico Interstate Stream Commission has constructed 121 ha of floodplain habitat between the river levees to improve habitat. To determine if constructed habitats were being utilized by the Rio Grande silvery minnow and the fish community, a presence/absence study was conducted on eight constructed floodplains during 2008 and 2009, and one natural floodplain in 2008. A total of 14 481 fish were captured in fyke nets during both years: 3528 fish were captured from constructed floodplains and 8410 were captured from the natural floodplain in 2008: 2543 fish were captured from the constructed floodplains in 2009. Of this total, 11 602 of the fish were Rio Grande silvery minnow: 2180 Rio Grande silvery minnow were collected from constructed floodplains and 7356 from the natural floodplain in 2008; 2057 Rio Grande silvery minnow were collected from constructed floodplains in 2009. Gravid female and male expressing milt were collected both years. A total of 1173 unidentified larval fish and 363 Rio Grande silvery minnow eggs were also collected during the surveys. The results show that the Rio Grande silvery minnow and the fish community utilized the constructed and natural floodplains during the spring spawning season.

This book was released on 2014-07-23 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two in-situ exposure studies were conducted with the federally-listed endangered Rio Grande silvery minnow (Hybognathus amarus). One-year-old adults were exposed in cages deployed at three sites in the Middle Rio Grande, N. Mex., for 4 days to assess survival and for 26 days to evaluate survival, growth, overall health, and whole-body elemental composition. The test sites were located on the Pueblo of Isleta in the (1) main channel of the Middle Rio Grande, (2) 240-Wasteway irrigation return drain, and (3) wetted instream habitat created below the outfall of the 240-Wasteway irriga-tion return drain.

Download or read book Unsettled Waters written by Eric P. Perramond and published by University of California Press. This book was released on 2018-11-06 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the American West, water adjudication lawsuits are adversarial, expensive, and lengthy. Unsettled Waters is the first detailed study of water adjudications in New Mexico. The state envisioned adjudication as a straightforward accounting of water rights as private property. However, adjudication resurfaced tensions and created conflicts among water sovereigns at multiple scales. Based on more than ten years of fieldwork, this book tells a fascinating story of resistance involving communal water cultures, Native rights and cleaved identities, clashing experts, and unintended outcomes. Whether the state can alter adjudications to meet the water demands in the twenty-first century will have serious consequences.

Book excerpt: This article describes the initial season‐long yield trial of raising the endangered Rio Grande silvery minnow, Hybognathus amarus, in the conservation rearing facility at the Los Lunas Silvery Minnow Refugium. Ten thousand fish (90,900/ha) were stocked on June 22, 2010. Production was based on a total of 653 mL (5.936 L/ha) of 11‐37‐0 N‐P‐K and 5.5 kg (50 kg/ha) of alfalfa pellets. Fish were harvested in October; almost all were harvested 18–27 October. At stocking, fish averaged 21.7 mm total length and mean weight was 0.10 g. At harvest, fish averaged 48.98 mm and 1.12 g. Fish were sampled monthly, and increased lengths and weights through the study were significant (P = 0.05). Five thousand eight hundred ninety‐two fish were harvested (58.92% survival). Yield was 59.99 kg/ha. Temperature, dissolved oxygen (DO), pH, un‐ionized ammonia, nitrite, turbidity, alkalinity, and chloride were measured at seven sites throughout the outdoor refugium. Secchi disc visibility was measured in the stream and in the ponds. Only two variables (DO and pH) went outside permitted values, but were easily corrected. Harvest was difficult due to the many different naturalized areas consisting of varying depths, channel widths, and substrates.
