Preferred Temperatures

We used behavioral and physiological responses of larval sea lamprey, Petromyzon marinus, to temperature to describe the thermal niche and define optimal thermal habitat. Acclimation temperature had a weak direct positive effect on acute preferred temperatures in summer but no effect on acute preferred temperatures in winter tests. Swimming speed, mass, and acclimation temperature accounted for 66% of the variation in the active metabolic rate of larval sea lamprey. When larvae are swimming at their maximum prolonged rate, the relationship between temperature and metabolic rate is a unimodal curve, as has been found for more active fish species. The final preferred temperature in summer, 20.8 °C, is similar to the temperature at which maximum scope for activity occurs, approximately 19 °C. We propose the "fundamental thermal niche" of larval sea lamprey to be the range of temperatures between 17.8 and 21.8 °C. Some practical applications for the thermal niche are sketched with respect to the integrated management of sea lamprey in the Great Lakes.

Behavioural Manipulation

Sea Lamprey (Petromyzon marinus), invaded the upper Great Lakes in the early 20th century, precipitating abrupt declines ina number of native fish species. A recently proposed alternative method for the behavioural manipulation of Sea Lamprey populations is the use of conspecific damage-released alarm and predator cues as potential repellents. We examined whether larval Sea Lamprey (Petromyzon marinus) ammocoetes can be manipulated to emigrate from an area by labeling their habitat “risky” with the regular release of chemosensory alarm cues over several days. in a semi-natural laboratory environment, we exposed eight replicate groups of eight ammocoetes twice a day, for 7 days, to deionized water (control), ammocoete whole-body extract (damage-released alarm cue), and 2-phenylethylamine HCl (predator cue). None of the experimental stimuli induced emigration from the experimental arena. This approach does not hold any promise for ammocoete behavioural manipulation in the context of a Sea Lamprey integrated management program.

Preferred Temperatures

Preferred temperatures were determined for yearling lake trout acclimated to 5, 10, 15, and 20 C. Acclimation temperature had virtually no effect on preferred temperature. The final preferendum was 11.7 C, which is about 2 degrees C warmer than the temperature at which lake trout are most commonly caught in thermally stratified lakes.

Group living is widespread among animal species, and comes with a number of costs and benefits associated with foraging, predator avoidance and reproduction. It is largely unknown, however, whether individuals sacrifice exposure to their own preferred or optimal environmental conditions so they can remain part of a social group. Here, we demonstrate that individual three-spine sticklebacks vary in the degree to which they forego exposure to their preferred ambient temperature so they can associate with a group of conspecifics. Individual fish varied widely in preferred temperature when tested in isolation. When the same individuals were presented with a choice of a warm or cold thermal regime in the presence of a social group in one of the environments, fish spent more time with the group if it was close to their own individually preferred temperature. When a group was in a relatively cool environment, focal individuals that were more social deviated most strongly from their preferred temperature to associate with the group. Standard and maximum metabolic rate were not related to temperature preference or thermal compromise. However, individuals with a higher standard metabolic rate were less social, and so energetic demand may indirectly influence the environmental costs experienced by group members. The reduced tendency to engage with a social group when there is a large difference between the group temperature and the individual's preferred temperature suggests a role for temperature in group formation and cohesion that is mediated by individual physiology and behaviour. Together, these data highlight exposure to non-preferred temperatures as a potential cost of group membership that probably has important but to date unrecognized implications for metabolic demand, energy allocation, locomotor performance and overall group functioning.

The modal preferred temperatures of rainbow trout acclimated to 5 °C, 10 °C, 15 °C., and 20 °C. were determined photographically to be 16 °C, 15 °C., 13 °C, and 11 °C., respectively. The final preferendum was 13 °C. The phenomenon of decreasing preferred temperature with increasing acclimation temperature has not been reported for any other species of fish.

Sea Lampreys

Criteria for the classification of marks inflicted by sea lamprey (Petromyzon marinus) into nine categories were developed from laboratory studies in an attempt to refine the classification system used in field assessment work. These criteria were based on characteristics of the attachment site that could be identified under field conditions by unaided visual means and by touching the attachment site. Healing of these marks was somewhat variable and was influenced by the size of lamprey, duration of attachment, severity of the wound at lamprey detachment, season and water temperature, and by other less obvious factors. Even under laboratory conditions staging of some wounds was difficult, especially at low water temperatures. If these criteria are to be used effectively and with precision in the field, close examination of individual fish may be required. If the feeding and density of specific year-classes of sea lampreys are to be accurately assessed on an annual basis, close attention to the wound size (as it reflects the size of the lamprey's oral disc) and character of wounds on fish will be required as well as consideration of the season of the year in which they are observed.Key words: sea lamprey, attack marks, lake trout, Great Lakes
