“…The location and timing of white sturgeon spawning are not well understood, but it is generally thought that the sturgeon respond to increases in streamflow (Schaffter, 1997;Hildebrand and others, 1999;Paragamian and Wakkinen, 2011). They select areas in the channel that have the highest water velocity (Parsley and others, 1993;Parsley and Beckman, 1994;Billard and Lecointre, 2000). In the Kootenai River, for example, white sturgeon have only been found spawning in areas that have a mean water-column velocity of 0.8-2.8 meters per second (m/s; Parsley and others, 1993).…”

“…Research in the Columbia and Kootenai Rivers of the Pacific Northwest indicated that high streamflow velocity and coarse bed material increased the survival of white sturgeon eggs and larvae (Parsley and others, 1993;Parsley and Beckman, 1994;Billard and Lecointre, 2000). Identifying the physical characteristics of the river where white sturgeon spawn can help protect their habitat and increase their survival to the larval drift stage of the life cycle.…”

“…Acipenseriformes, specifically pallid sturgeon, shovelnose sturgeon, and paddlefish, are long lived, reach sexual maturity late (5-15 years), and do not reproduce annually (Billard and Lecointre, 2001). These species each have adhesive eggs inferred to be deposited in the current over coarse substrate and a protracted free-embryo life stage that drifts for several days after hatching.…”

AbstractThe Comprehensive Sturgeon Research Project is a multiyear, multiagency collaborative research framework developed to provide information to support pallid sturgeon recovery and Missouri River management decisions. The project strategy integrates field and laboratory studies of sturgeon reproductive ecology, early life history, habitat requirements, and physiology. The project scope of work is developed annually with collaborating research partners and in cooperation with the U.S. Army Corps of Engineers, Missouri River Recovery Program-Integrated Science Program. The project research consists of several interdependent and complementary tasks that involve multiple disciplines.The project research tasks in the 2014 scope of work emphasized understanding of reproductive migrations and spawning of adult pallid sturgeon and hatch and drift of larvae. These tasks were addressed in three hydrologically and geomorphologically distinct parts of the Missouri River Basin: the Lower Missouri River downstream from Gavins Point Dam, the Upper Missouri River downstream from Fort Peck Dam and downstream reaches of the Milk River, and the Lower Yellowstone River. The project research is designed to inform management decisions related to channel re-engineering, flow modification, and pallid sturgeon population augmentation on the Missouri River and throughout the range of the species. Research and progress made through this project are reported to the U.S. Army Corps of Engineers annually. This annual report details the research effort and progress made by the Comprehensive Sturgeon Research Project during 2014.

“…Due to their instinctive behavior, most species of Acipenseriformes have critical requirements for spawning conditions (Billard and Lecointre 2001), and show a homing fidelity to some particular spawning areas (Bemis and Kynard 1997). Sturgeon reproductive success is influenced by many environmental factors, such as water temperature, water level, discharge, current velocity and riverbed substrate (Dettlaff et al 1993;Billard and Lecointre 2001).…”

“…Sturgeon reproductive success is influenced by many environmental factors, such as water temperature, water level, discharge, current velocity and riverbed substrate (Dettlaff et al 1993;Billard and Lecointre 2001). Results from previous research have suggested that geomorphic characteristics are likely important in regulating other microhabitat variables (e.g., substrate quality, hyporheic exchange, hydraulic habitat complexity) important to spawning fish (Baxter and Hauer 2000;Keckeis 2001; Moise and Michel 2004;Moir et al 2006).…”

A bedform morphology hypothesis for spawning areas of Chinese sturgeon

Results from previous research suggested that geomorphic characteristics may be important controlling factors among other microhabitat variables for spawning fish. We investigated the bedform morphology of seven spawning areas (five historic and two present spawning areas) of Chinese sturgeon (Acipenser sinensis) by analysis of relief maps of the riverbed and by field surveys. We conclude that the topographic characteristics of the spawning areas include rocky or gravelly substrate river bend, large variations in water depth and river width and a slope with moderate length and slope. The turning structure and the adverse slope may be the most important topographic characteristics for the spawning areas. Combined with the reproductive occurrence of the fish in these spawning areas, we tentatively propose a bedform morphology hypothesis for the spawning areas. We consider that a spawning area of A. sinensis should consist of three functional areas: Mating area (M), Dispersal area (D) and Incubation area (I). M, D and I are distributed along the water current and their bedform characteristics are clearly different. M is the place for mature fish to mate and spawn. It is usually below a riffle with rolling terrain. D is the place for fertilizing and dispersing fertilized eggs. It is usually in a river bend with sharp variations in terrain, such as deep pools or steep slopes. I is the place for dispersal of fertilized eggs. It is usually in long point bars or broad shallow areas with rocky substrate. This hypothesis could serve as a guideline for improving the present spawning areas or constructing new spawning areas, so as to rehabilitate the wild stock of the sturgeon.
