“…In this manner, development occurs by a process of saltation. Although there have been previous studies of various aspects of the early life history of the white sucker (Crawford 1923, Stewart 1926, Fish 1932, Raney & Webster 1942, Carbine 1943, Geen 1958, Geen et al 1966, Nelson 1968, Oseid & Smith 1971, Clifford 1972, Siefert & Spoor 1974, Long & Ballard 1976, McCormick et al 1977, Fuiman 1978, Buynak & Mohr 1978 none have emphasized ecomorphological relationships, nor demonstrated the steps and thresholds of saltatory development during the embryonic period.…”

SynopsisFrequent and detailed observations of arbitrary stages revealed a saltatory pattern of development in the early ontogeny of fluvial spawning white sucker. Considered as adaptations for respiration were: i) expansion of the surface area of the yolk through a change in yolk shape, ii) the presence of carotenoid pigment in the yolk, iii) a large caudal vein sinus, iv) coverage of the yolk surface with capillaries of bilaterally paired vitelline plexi, and v) a large pair of vitelline veins. The ability to swim developed slowly and well after hatching. Young suckers would therefore spend most of the eleutheroembryonic phase in the interstices of the rock substrate of the spawning ground. The change from a benthic to pelagic mode of existence occurred with swimbladder inflation and before the start of exogenous feeding.
