Characterization of cannibalism in early paralarvae of Patagonian red octopus, Enteroctopus megalocyathus (Gould, 1852), grown in a controlled environment [PDF]

Journal of the World Aquaculture Society, 2021
In the experimental mariculture of Patagonian red octopus, Enteroctopus megalocyathus, paralarvae rearing showed the highest mortalities. Part of this mortality has been attributed to cannibalism, so we studied the joint effect of paralarvae density and ...

Overview of Patagonian Red Octopus (Enteroctopus megalocyathus) Fisheries in Chilean Regions and Their Food Safety Aspects [PDF]

Animals
Artisanal fisheries in southern Chile rely heavily on the Patagonian red octopus (Enteroctopus megalocyathus) as a valuable resource, contributing significantly to local economies. This octopus species accounts for 25–40% of Chilean octopus landings.

Effect of broodstock diet on the fecundity and biochemical composition of eggs of the Patagonian red octopus (Enteroctopus megalocyathus Gould 1852)

Ciencias Marinas, 2010
Twelve females of the Patagonian red octopus Enteroctopus megalocyathus, of 1.4 ± 0.2 kg, were maintained at 12 ºC under three conditioning treatments: T1 (F10%), frozen fish at 10% daily body weight (bwt d–1); T2 (FC (3:1) 10%), mix (3:1) of frozen ...

Performance Parameters of Paralarvae and Postparalarvae Rearing of Patagonian Red Octopus, Enteroctopus megalocyathus, under Experimental Conditions

Aquaculture Research, Volume 2024, Issue 1, 2024.
Patagonian red octopus, Enteroctopus megalocyathus, an interesting species for Chilean aquaculture diversification, requires the improving of their experimental technology to obtain early juveniles. The first objective of the study was to enhance aspects of feeding and temperature management in broodstock, egg incubation, paralarvae rearing, and early ...

Systematics and Phylogenetic Relationships of New Zealand Benthic Octopuses (Cephalopoda: Octopodoidea)

Frontiers in Marine Science, 2020
The systematics of the New Zealand octopods have only been reviewed twice in the last 100 years. In these revisions many species have been provisionally classified in the genus Octopus.

The effectiveness and impact of disinfection with chlorine on embryos and early hatchlings of two Western Pacific octopus species

Journal of the World Aquaculture Society, Volume 55, Issue 4, August 2024.
Abstract Replicating maternal care and incubating octopus embryos artificially is advantageous to improve access to embryonic stages, split and share broods, and reduce the required space to culture large quantities of embryos. However, without female care and adequate rearing systems, the risk of bacterial and fungal infections can be high. This study

Uso del microhábitat por el protozoo parásito Aggregata patagonica Sardella, Ré & Timi, 2000 (Apicomplexa: Aggregatidae) en su hospedador definitivo, el pulpo Enteroctopus megalocyathus (Gould, 1852) (Cephalopoda: Octopodidae) en el sur de Chile Microhabitat use by the protozoan parasite Aggregata patagonica Sardella, Ré & Timi, 2000 (Apicomplexa: Aggregatidae) in his definitive host Enteroctopus megalocyathus (Gould, 1852) (Cephalopoda: Octopodidae) in southern Chile

Revista Chilena de Historia Natural, 2005
Los protozoos de la familia Aggregatidae requieren de dos hospedadores para completar su ciclo biológico: un crustáceo y un cefalópodo. En este estudio se busca evidenciar si existe un uso diferencial de microhábitats de las infrapoblaciones de Aggregata
