By Philip Brownell Armstrong Topics: Brown bullhead, Embryology, FishesAuthor: Philip Brownell Armstrong.   ABSTRACT. A population of brown bullheads (Ictalurus nebulosus Leuseur) in Muskellunge Lake, New York was investigated to determine population density, age structure, sex ratio, fecundity, survivorship, growth, and the intrinsic rate of population population density estimate was ( ≤ N ≤ ) per ha. The instantaneous rate of survivorship for females () Cited by: Training experiments: a) When the catfish Ictalurus nebulosus (Amiurus nebulosus) is moving, it can perceive an inhomogeneous d. c. field (current density A/mm2, current density gradient 0.

ents guarded the nest (Blumer, ). The larval stage of development (see Armstrong, ) was noted infrequently, but among 12 broods, larvae were first observed between June. The larval stage lasted a maximum of 6 days and was followed by the juve-nile stage of development. Juveniles were first observed between 12 June and 18 July. Groups of year 0 and year 2 brown bullhead (Ictalurus nebulosus) that had concluded the summer's growth, were exposed to six different temperatures between 5 and 30 °C for 8 weeks. T.J. Hara, in Encyclopedia of Fish Physiology, General. The pioneering recordings of electrical responses of facial nerve in response to various stimuli in bullhead catfish (Ameiurus nebulosus) by Hoagland in clearly demonstrated that the fish gustatory systems are very sensitive to mechanical stimuli (touch and water current) but generally insensitive to the classical vertebrate. The brown bullhead (Ameiurus nebulosus) is a fish of the Ictaluridae family that is widely distributed in North America. It is a species of bullhead catfish and is similar to the black bullhead (Ameiurus melas) and yellow bullhead (Ameiurus natalis).It was originally described as Pimelodus nebulosus by Charles Alexandre Lesueur in , and is also referred to as Ictalurus nebulosus.

White sucker, Catostomus commersoni (Lacépède), and brown bullhead, Ictalurus nebulosus (Lesueur), populations throughout the Great Lakes examined for evidence of pollution associated neoplasia exhibited a variety of morphologically distinct skin lesions. Three types of skin lesions affected white suckers: (a) focal on the lips, (b) discrete on the body, or (c) raised mucoid focal. Jagmeet S.
