Cumulative impacts assessment along a large river, using brown bullhead catfish (Ameiurus nebulosus) populations.
The effects of point-source and diffuse discharges on resident populations of brown bullhead catfish (Ameiurus nebulosus (LeSueur, 1819)) in the Waikato River (New Zealand) were assessed at sites both upstream and downstream of point-source discharges. At each site, the population parameters, relative abundance, age structure, and individual indices, such as condition factor, organ (gonad, live...
متن کاملAuditory sensitivity in the bullhead catfish (Ictalurus nebulosis).
The auditory sensitivity of 4 specimens of the bullhead catfish (Ictalurus nebulosis) was determined by shock-avoidance training in an aquatic shuttle box. The range of hearing extended from 100 to 4000 cycles per second, with the maximum sensitivity around 600 to 700 cycles per second.
متن کاملPollution-induced behavioural effects in the brown bullhead (Ameiurus nebulosus).
Aquatic ecosystems are major sinks for pollutants which can have adverse effects on biodiversity. Thus, it is important to understand the nature of pollution-induced change in aquatic ecosystems. We show that brown bullheads (Ameiurus nebulosus) may have evolved in response to chronic pollution exposure. We collected adults from the Detroit River (polluted site) and Belle River (control site). ...
متن کاملOlfactory discrimination of amino acids in brown bullhead catfish.
Olfactory discrimination of amino acids was investigated in brown bullhead catfish (Ameiurus nebulosus). Based on the magnitude of the observed food search activity of catfish conditioned to single amino acids, the tested compounds were classified as being detected by the catfish as equal to, similar to, or different from the conditioned stimulus. L-Proline (L-Pro)-conditioned brown bullhead ca...
متن کاملInsulin biosynthesis in the bullhead, Ictalurus nebulosus, and the effect of temperature.
Insulin biosynthesis in the brown bullhead, Ictalurus nebulosus (Le Sueur), was studied by measuring the incorporation in vitro of [(3)H]leucine into proteins of the principal islet. The tissue was incubated for 6-15h in Krebs-Ringer bicarbonate buffer with [(3)H]leucine, supplemented with amino acids and glucose. Proteins, precipitated with trichloroacetic acid and extracted with acid ethanol,...
