Objectives and Tasks

Objective Task
1. Examine the relation between telemetered physiological variables, oxygen consumption, and physiological indicators of stress in white sturgeon. a. Obtain or construct a swimming respirometer for large fish. Set up wet laboratory holding and testing facilities.
. b. Obtain physiological telemetry tags & related equipment for lab testing to include heart rate, ventilation rate, EMG tags; tags can be reused. Obtain detailed instructions & methods for surgical implantation of tags.
. c. Collect white sturgeon from the Columbia River and transport them to our laboratory. Maintain fish under ambient conditions. Fish should be about 0.9-1.5 m in length. Hold fish for several weeks prior to testing
. d. Surgically implant tags. Cannulate fish for repeated blood sampling. Check for proper operation of biotelemetry system.
. e. Subject fish to a respirometry trial. Conduct a U-critical swimming challenge with fish while simultaneously measuring oxygen consumption, monitoring telemetry signals (i.e., heart rate, ventilation rate, or EMG), and periodically taking blood samples
. f. Examine relations between telemetered data, oxygen consumption, physiological indicators of stress, and individual fish. Derive best fit regression equations for the relation between telemetered data and oxygen consumption.
2. Assess the effects of catch and release angling on metabolic rate and selected physiological indicators of stress in wild white sturgeon a. From the wild, capture several large sturgeon. Transport fish to laboratory and surgically implant tags or implant tags in situ. Monitor recovery from surgery, tag implantation, & tag output for a few days.
. b. Release fish back to point of capture, or transport to smaller, isolated backwaters. Monitor physiological function & movement for several weeks to establish baseline metabolic rate data.
. c. Using telemetry, locate fish & capture tagged fish by angling. Monitor physiological function during angling. Monitor hookup and playing time. Upon landing, draw blood sample, photograph fish & surgery site, release fish.
. d. Determine stressful effects of angling. Monitor after release for several days. Compare response to angling with baseline data. Assess rate of recovery, correlate metabolic data with physiological information obtained in laboratory.
3. Document the occurrence and determine the extent of any postangling mortality a. Use physiological telemetry and fish movement and location data to assess postangling mortality
4. Assess the effects of exhaustive stress on selected aspects of white sturgeon reproductive performance a. Locate facilities for long term rearing of large, broodstock sturgeon. This could be at our laboratory or an established sturgeon aquaculture facility
. b. Obtain mature female sturgeon from wild or aquaculture facility. Stock in each of 4 large tanks for rearing. There will be 2 treatments (stressed & controls) with 2 replicate tanks per treatment. Maintain fish under ambient conditions.
. c. During rearing, monitor reproductive physiology and state of maturation by periodically sampling blood for sex steroid analysis and conducting ovarian biopsies as per standard aquaculture procedures.
. d. Administer stressors to fish in 2 tanks at selected intervals: dewatering & hypoxia, chasing until exhaustion, and netting fish and suspending in air.
. e. Spawn treatment and control fish using a single sperm sample and standard aquacultural methods. Record female weight, total length, weight of the eggs, and ovarian fluid weight
. f. Using subsamples of eggs from each female, weigh & measure diameter. Determine gonadosomatic index, absolute & relative fecundity, percentage of fertilized eggs for each female.
. g. Determine the mean percent of embryos hatching and monitor growth of fry at 2, 4, 6, and 8 weeks after absorption of the yolk sac. Monitor embryo, fry, and juvenile mortality twice a week.

Other Budget Explanation

Schedule Constraints: It will likely be necessary to have objective 1 mostly complete before commencing objectives 2 and 3. Any delays to objective 1 will cause delays in other objectives. To put the complete focus on objective 1 during the first year, objective 4 will be delayed one year.

Section 7. Abstract


The white sturgeon is a species critically affected by hydroelectric development. Because of the declining status of many sturgeon populations, catch and release angling has become a central part of current fisheries management activities directed at sustaining or recovering populations of these fish. However, the potential detrimental effects of catch and release angling on these fish have never been addressed. We propose to examine the effects of catch and release angling on the stress physiology, reproductive physiology, and mortality of white sturgeon in laboratory and field studies. This research will use a multi-disciplinary approach that will focus on state-of-the-science physiological telemetry techniques to assess the effects of angling stress on fish in the wild. Data from the laboratory on the physiological responses and metabolic costs of physical stress in white sturgeon will be coupled with metabolic rate data obtained by physiological telemetry from fish angled in the wild to allow an assessment of catch and release angling. This project should be relevant to the resident fish goal and sturgeon mitigation as described in section 10 of the FWP. Results from this study should be complete within 3-4 years and will enable fisheries managers to make more informed decisions regarding the use of catch and release angling as a management tool for sustaining or recovering populations of white sturgeons. The study could be used to decide if seasonal closures to angling are warranted to protect spawning fish or to improve survival of fish during the summer when water temperatures are at their highest.
