“…In the open‐water season, E. maxillingua inhabits clear, shallow, rocky reaches within small streams (Bean, ; Scott & Crossman, ). During the breeding season in late spring, males build nests by carrying pebbles in their mouths and arranging them into mounds with a diameter of up to 45 cm (Hankinson, ; van Duzer, ). Nest construction usually occurs behind rocks or other obstructions that create eddies or calm areas in reaches of otherwise fast‐flowing streams.…”

“…Unlike some Cyprinid taxa, E. maxillingua do not exhibit nuptial pigmentation or other secondary sexual dimorphism (Scott & Crossman, ). However, like many minnow species, the male E. maxillingua is responsible for nest construction and maintenance (Hankinson, ; Maurakis et al ., ). Our results demonstrate that E. maxillingua nesting materials exhibit similar dominant wavelengths to surrounding materials.…”

We compared size and colour characteristics of rocks used by male cutlip minnows Exoglossum maxillingua to build nests to those of streambed background materials. We found that materials used to construct conspicuous, mound-shaped nests were uniform in size and darker and more colour-saturated than background materials of the same size. To our knowledge, this phenomenon is the first reported example of fish selecting nest materials based on colour and has important implications for the conservation of mound-nesting stream cyprinid species.

“…It has been found in depths of 0.15 to 1.2 m, in water with temperatures ranging from 0 to 26°C, and over firm bottoms of rubble, gravel, boulders, and cobbles. Instream cover such as large rocks, logs, vegetation, or overhanging banks is an important component of the habitat of this species (Hankinson 1922;Van Duzer 1939;Haase and Haase 1975;Cooper 1983;Pappantoniou 1983;Smith 1985). In Connecticut, total alkalinity ranged from 7 to 137 and hardness 22 to 184 both mg/l equivalent CaCo,.…”

The Cutlips Minnow, Exoglossum maxillingua, is a stout bodied minnow distinguished from all other members of the family Cyprinidae in North America by its unique trilobed lower jaw. It is common in many upland regions of the Atlantic coast drainage of northeastern North America. It is rare, and there is evidence that populations have declined from levels in the 1930s in Ontario. It is more widespread in Québec where it has been found in numerous river systems from 1935 to 1989. Since 1977, there has been a significant decrease in the number of surveys in the limited area occupied by this species in Canada. Surveys might have provided more information on present status. There is, however, evidence of low and/or declining numbers in some river systems.Le bec-de-lievre, Exoglossum maxillingua, est un méné au corps trapu qui se distingue de tous les autres membres de la famille Cyprinidae en Amérique du Nord par sa machoire inférieure trilobée. Il est répandu dans de nombreuses régions hautes du bassin versant de ]'Atlantique dans le nord-est de l'Amérique du Nord. On le rencontre rarement en Ontario, ou sa population enregistre une baisse par rapport aux chiffres des années 1930. Il est plus répandu au Québec ow I'on a relevé sa présence dans nombre de réseaux fluviaux de 1935 a 1989. Depuis 1977, le nombre d'études effectuées dans la région restreinte occupée par cette espéce au Canada a diminué de fagon marquée. Si tel n'avait pas été le cas, nous disposerions probablement de plus de données sur la situation actuelle de l'espéce. I] semblerait toutefois que sa population est faible ou a la baisse dans certains réseaux.
