Effects of stocking density on growth of channel catfish, Ictalurus punctatus, fingerlings in Southern Brazil
(1997-12-01)
Channel catfish, Ictalurus punctatus, fingerlings (mean length: 4.0±0.5 cm) were stocked into sixteen 16-m2 tanks with cement walls and earth bottoms. Four stocking densities were used: 10, 15, 20, and 25 fish/m2. Fish ...
General Hydrography of the Beagle Channel, a Subantarctic Interoceanic Passage at the Southern Tip of South America
(Frontiers Media, 2021-10)
The Beagle Channel (BC) is a long and narrow interoceanic passage (∼270 km long and 1–12 km wide) with west-east orientation and complex bathymetry connecting the Pacific and Atlantic oceans at latitude 55°S. This study ...

Occurrence of dusky dolphin lagenorhynchus obscurus in Tierra Del Fuego archipelago over five decades
(Springer, 2018-09-27)
Dusky dolphins Lagenorhynchus obscurus are distributed in circumpolar temperate and cold temperate waters of the Southern hemisphere. In Tierra del Fuego, their presence had been considered occasional but in the last decade, ...

Extraordinary sediment delivery and rapid geomorphic response following the 2008–2009 eruption of Chait en Volcano, Chile
(American Geophysical Union, 2016)
The 10 day explosive phase of the 2008-2009 eruption of Chaiten volcano, Chile, draped adjacent watersheds with a few cm to >1 m of tephra. Subsequent lava-dome collapses generated pyroclastic flows that delivered additional ...
Distribution of dinoflagellate cysts and other aquatic palynomorphs in surface sediments from the Beagle Channel, Southern Argentina
(Elsevier Science, 2012-12)
Palynological analyses of 22 surface sediment samples from the Beagle Channel, Tierra del Fuego, Argentina, were performed in order to investigate the distribution of dinocyst assemblages and other aquatic palynomorphs and ...
Temporal and spatial adjustments of channel migration and planform geometry: responses to ENSO driven climate anomalies on the tropical freely-meandering Aguapeí River, São Paulo, Brazil
(2018-06-30)
Two reaches of Aguapeí River, a left-bank tributary of the Paraná River in western São Paulo state, Brazil, were studied with the objective of assessing the role of bend curvature on channel migration in this wet-tropical ...
Middle-Late Holocene palynology and marine mollusks from Archipiélago Cormoranes area, Beagle Channel, southern Tierra del Fuego, Argentina
(Elsevier Science, 2009-03)
The palynology and marine mollusks of a marine sequence from Río Ovando (54° 51′ S, 68° 35′ W), Archipiélago Cormoranes, Beagle Channel, has been studied in order to reconstruct paleoenvironmental conditions during the ...
Growth of Channel Catfish, Ictalurus punctatus, in Southern Brazil
(1998-12-01)
Despite successful introduction of channel catfish into Brazil in 1980, no studies have been conducted to assess the performance of channel catfish, Ictalurus punctatus, farming in southern Brazil. Fingerlings (27.0 ± 2.2 ...
