Description

Notice of Intent to negociate a sole source purchase order utilizing Simplified Acquisition Procedures with Bio-West,1063 West 1400 North, Logan, UT 84321,Woundfin monitoring in the study of the lower Virgin River is currently underway. This includes monitoring a minimum of each month, with twice monthly monitoring during the summer of 2001 and two months following additional woundfin stocking. This study would add efforts related to determining food habits of red shiner and woundfin during summer, fall, winter, and sprig in the same habitats, the availability of food items during those periods, and how food habits change with variations in flow, habitat use, and res shiner density. This study would require developing new techniques and methodologies and, therefore, is a reconnaissance level study. The objectives of the study are as follows: 1. Determine the seasonal food habits of woundfin and redshiner adults and young form the same habitats. 2. Determine the availability of food items seasonally in the Virgin River. 3. Determine if food habits vary between different habitats in the study reach, and if they vary with flooding events. 4. Determine the potential for competition between the two species and whether food limitation is a concern the Virgin River. This study will require developing a technique to use stomach pumping on wild woundfin, so gut contents can be determined with out sacrificing the fish. Development of this technique will allow for assessment of food habits seasonally, by habitat type, in areas with large number of re shiner, in areas with few red shiner, and immediately after flood events. Methods of determining food availability will involve collection of benthic macro invertebrates form riffles, drifting particles in runs, and perhaps collection of food items form other portions of the river. Pumping stomachs will allow a field review of items being eaten, and the goal will then be to determine where those food items are produced (within the river or outside), and what is the abundance of food items. This may require development of sampling techniques that are not standard to stream sampling. The study would be conducted during summer, fall, winter beginning in the summer of 2001. A final report would be required September 30,2002. This is a simplified Acquisition with an estimated value of less than $50,000. Questions concerning this acquisition may be directed to Albert Richard at 702-293-8601 or fax 702-293-8050
