Revision of the population structuring of Illex argentinus (Castellanos, 1960) and a new interpretation based on modelling the spatio-temporal environmental suitability for spawning and nursery
(Wiley Blackwell Publishing, Inc, 2012-03)
During the last 30years, interpretation of the population structuring of Illex argentinus evolved from a single to a six-stock model, in which stocks are characterized by having distinct spawning seasons, areas and migration ...
Brazilian sardine (Sardinella brasiliensis Steindachner, 1879) spawning and nursery habitats: spatial-scale partitioning and multiscale relationships with thermohaline descriptors
(OXFORD UNIV PRESSOXFORD, 2012)
We provide a detailed account of the spatial structure of the Brazilian sardine (Sardinella brasiliensis) spawning and nursery habitats, using ichthyoplankton data from nine surveys (1976-1993) covering the Southeastern ...
Dynamics of the Confluence of Malvinas and Brazil currents, and a southern Patagonian spawning ground, explain recruitment fluctuations of the main stock of Illex argentinus
(Wiley Blackwell Publishing, Inc, 2020-09)
The Argentine shortfin squid (Illex argentinus) sustains one of the world's largest squid fisheries. This squid presents strong interannual fluctuations in abundance, attributed to its semelparous life strategy coupled ...
Spatial patterns of copepod biodiversity in relation to a tidal front system in the main spawning and nursery area of the Argentine hake Merluccius hubbsi
(Elsevier Science, 2014-08)
Copepods play an important role in marine ecosystems as a direct link of energy transfer between primary producers and higher trophic level consumers, such as fish. In the Argentine Sea, the Patagonian stock of Argentine ...
Inshore spawning grounds of the squid doryteuthis gahi suggest the consistent use of defoliated kelp lessonia trabeculata in central chilean waters
(2016)
Coastal spawning grounds of the squid Doryteuthis gahi were identified for the first time at three sites in Central Chile during 2014 and 2015. A total of 15 egg masses were collected from between 10 and 15 m depth and ...
Comparative study of spawning pattern and reproductive potential of the Northern and Southern stocks of Argentine hake (Merluccius hubbsi)
(Elsevier Science, 2015-08)
The reproductive biology of the Northern (Bonaerense) and Southern (Patagonian) stocks of M hubbsi in the Argentine Sea is analyzed, including information on spawning areas, estimates of abundance and size composition of ...
Larval condition of Merluccius hubbsi (Marini, 1933) in the northern Patagonian spawning ground
(Elsevier Science, 2014-08)
Argentinean hake, Merluccius hubbsi, is one of the most important fishery resources of the South-western Atlantic Ocean, but its spawning biomass decreased in the last fifteen years, mainly due to the increased fishing ...
