New Challenges

Climate-related changes in fish communities can present new challenges for fishery managers who must address declines in cool- and cold-water sportfish while dealing with increased abundance of warm-water sportfish. We used largemouth bass (Micropterus salmoides) in Wisconsin lakes as model populations to determine whether angler harvest provides a realistic method for reducing abundance of a popular warm-water sportfish that has become more prevalent and has prompted management concerns around the globe. Model results indicate largemouth bass will be resilient to increased fishing mortality. Furthermore, high rates of voluntary catch-and-release occurring in most largemouth bass fisheries likely preclude fishing mortality rates required to reduce bass abundance at meaningful levels (≥25% reductions). Increasing fishing mortality in these scenarios may require more “stimulus” than merely providing anglers with greater harvest opportunities via less stringent harvest regulations. Angler harvest could result in populations dominated by small fish, a scenario that may be undesirable to anglers, but could provide ecological benefits in certain situations.

Increasing Temperature

Acute cold stress caused increased predation on juvenile channel catfish (Ictalurus punctatus) and largemouth bass (Micropterus salmoides) by unstressed adult largemouth bass when temperature differentials were 9 and 7 C or more, respectively, (base temperatures 16 and 17 C). Predation rate tended to increase exponentially with increasing temperature differential. Catfish held 1 h in the cold water were only slightly less susceptible to predation than were others tested immediately after the temperature change.

Linear Regressions

Oxygen consumption was determined for largemouth bass, Micropterus salmoides, of various sizes in relation to sustained swimming speeds. The logarithm of oxygen consumption for a given swimming speed and temperature increased linearly with the logarithm of weight. Slopes of regressions were considerably less than unity. In general, slopes for different swimming speeds at a given temperature did not differ significantly. The relation between logarithm of oxygen consumption and swimming speed is expressed as a series of parallel, linear regressions for the temperatures followed. For a given swimming speed, oxygen consumption increased with temperature from 10 to 34 C, the highest temperature followed.Active oxygen consumption increased linearly with weight when expressed on a logarithmic grid. At each temperature the slope of the regression approached unity. The logarithm of standard oxygen consumption increased linearly with temperature from 10 to 34 C.The logarithm of maximum sustained swimming speed increased linearly with total length at each temperature. For a given total length, maximum sustained swimming speed increased from 10 to 30 C. Between 30 and 34 C maximum speed decreased.

We used frame-by-frame analysis of high-speed videotapes to quantify midline kinematics during steady swimming in largemouth bass at five standardized speeds (0.7, 1.2, 1.6, 2.0 and 2.4 L s-1, where L is total length). By combining morphological data from X-ray photographs with mathematical reconstructions of the midline of each fish, we determined the amplitude and timing of lateral displacement (zmax), lateral flexion (ssmax) and the angle between the midline and the axis of forward travel (thetamax) for each vertebral joint, the hypural bones and four equally spaced segments of the caudal fin rays. Analysis of variance revealed pervasive significant effects of both swimming speed and longitudinal location on variables describing amplitude, phase and wavelength. The amplitudes of zmax, ssmax and thetamax generally increased in a non-linear fashion from approximately 25 %L to the tip of the caudal fin, and the greatest speed-related increases occurred between 0.7 and 1.6 L s-1. For the snout, the first caudal vertebra and the trailing edge of the caudal fin, mean values of zmax increased with speed from 0.004 to 0.012 L, from 0.005 to 0.012 L and from 0.053 to 0.066 L, respectively. For joints between the skull and the first vertebra, between the trunk and the tail vertebrae, and among the most posterior caudal vertebrae, mean values of ssmax increased with speed from 1.2 to 1.7 degrees, from 0.6 to 0.9 degrees and from 1.4 to 2.2 degrees, respectively. Within each swimming speed, values of ssmax of the distal caudal fin commonly exceeded twice those of the proximal caudal fin. Surprisingly, at a given longitudinal location, the times of maximum lateral displacement and bending did not occur simultaneously. Instead, the phase of zmax relative to ssmax was commonly shifted by more than one-sixth of a cycle. Furthermore, the phase shift between zmax and ssmax changed significantly with increased swimming speed. Angles of attack of the tail structures changed periodically from negative to positive values. Maximum angles of attack of the distal caudal fin ranged from 5 to 17 degrees, changed significantly with swimming speed and were less than those of the hypural bones of the tail. Mean tail-beat frequency increased significantly from 2.0 to 4.2 Hz with increased swimming speed. Estimated speeds of wave propagation showed considerable longitudinal variation, and the ratio of swimming speed to posterior wave speed increased from 0.59 to 0.83 with increased swimming speed.
