Trophic niche changes during settlement in the Argentine hake Merluccius hubbsi reveal the importance of pelagic food post metamorphosis
(Inter-Research, 2019-06)
Among those factors that determine the success of a fish cohort, trophic interactions play a key role, especially during the larval and juvenile stages. The Argentine hake Merluccius hubbsi is the most abundant demersal ...
New insights on reproductive features in Lepidonotothen nudifrons (Pisces, Notothenioidei) at the south Shetland Island, supported by physiological evidence
(Asociación Latinoamericana de Investigadores en Ciencias del Mar, 2019)
The Southern Ocean marine ichthyofauna is dominated by a unique costal demersal fish group, the suborder Notothenioidei. The nototheniid Lepidonotothen nudifrons is abundant in nearshore waters of the Scotia Arc region, ...
Life strategies of some long-distance migratory catfish in relation to hydroelectric dams in the Amazon Basin
(1991-12-01)
In this paper, we present evidence that the long-distance migratory catfish Brachyplatystoma filamentosum, B. flavicans, B. vaillantii, Goslinia platynema and Lithodoras dorsalis spawn in the headstreams of the Amazon river ...
Genomic variation underlying complex life-history traits revealed by genome sequencing in Chinook salmon.
A broad portfolio of phenotypic diversity in natural organisms can buffer against exploitation and increase species persistence in disturbed ecosystems. The study of genomic variation that accounts for ecological and ...
The São Paulo shelf (SE Brazil) as a nursery ground for Doryteuthis plei (Blainville, 1823) (Cephalopoda, Loliginidae) paralarvae: a Lagrangian particle-tracking individual-based model approach
(SpringerCham, 2014)
The São Paulo shelf ranges from ~23ºS to 25ºS, comprising nearly 622 km of shoreline. This region sustains historical landings of the tropical arrow squid Doryteuthis plei. As in other coleoid cephalopods, the broodstock ...
Spatial and temporal patterns in size and maturation of Loligo plei and Loligo sanpaulensis (Cephalopoda: Loliginidae) in southeastern Brazilian waters, between 23 degrees S and 27 degrees S
(INST CIENCIAS MAR BARCELONA, 2008)
Patterns of population dynamics of Loligo plei and Loligo sanpaidensis in Southeastern Brazil were investigated with samples obtained from commercial catches and research cruises from 1999 to 2000 and from 2002 to 2003. ...
Salilota australis
(International Union for Conservation of Nature, 2020-12)
This widely distributed, demersal species has an estimated generation length of 10 years. It is a valued bycatch species retained in bottom trawl fisheries throughout its range. Exploitation of spawning aggregations increases ...
Intertidal Fishery of the Patagonian Red Octopus, Enteroctopus megalocyathus (Gould 1852): Reproductive Status and Catch Composition in the North of San Jorge Gulf (Patagonian Atlantic Coast)
(National Shellfisheries Association, 2019-12)
Enteroctopus megalocyathus is one of the most important octopus fishing resource in Patagonian Atlantic and Patagonian Pacific coasts, but there is no information available regarding the biological aspects of the species ...
