Embryonic development of the southern surf crab Ovalipes trimaculatus (Decapoda: Brachyura: Portunoidea)Desarrollo embrionario del cangrejo nadador Ovalipes trimaculatus (Decapoda: Brachyura: Portunoidea)
(Instituto de Ciencias del Mar Barcelona, 2016-03)
The embryogenesis of Ovalipes trimaculatus, a member of the highly valued portunid swimming crabs, was studied under nearly constant temperature (13±1°C), salinity (33) and photoperiod (14 h light:10 h dark) conditions. A ...
Rearing enhancement of Ovalipes trimaculatus (Crustacea: Portunidae) zoea I by feeding on Artemia persimilis nauplii enriched with alternative microalgal diets
(Springer Nature Limited, 2020-12)
The southern surf crab Ovalipes trimaculatus (de Haan, 1833) presents a high potential for aquaculture. In this study, we analyze the benefits of different dietary treatments on its molt success and fitness of larval stages. ...
Functional morphology of the gastric mill of the swimming crab Ovalipes trimaculatus (Decapoda: Portunidae)
(Cambridge University Press, 2017-05)
The stomach of Decapod crustaceans is a complex structure with great interspecific variation. Several studies suggest that the anatomy of the gastric mill varies according to the diet of species in different groups. An ...
Molt cycle stages of the paddle crab ovalipes trimaculatus (de hann, 1833) based on observations of the external morphology
(UNIV VALPARAISO, 2009)
The knowledge of molt cycle in crustaceans is important from the physiological point of view and because it can be used in aquaculture and fisheries management. Ten specimens of Ovalipes trimaculatus were held in laboratory ...
Predicting the distribution of a portunid crab in Patagonian coastal waters
(Inter-Research, 2020-03)
Ovalipes trimaculatus is a commercially important, cosmopolitan portunid crab.However, environmental conditions that drive its distribution have never been studied. Thus, we aimed to assess the habitat preferences of this ...
Marine pollution effects on the southern surf crab Ovalipes trimaculatus (Crustacea: Brachyura: Polybiidae) in Patagonia Argentina
(Elsevier, 2014-10-05)
We compared the carapace shape and thickness as well as the energy density of Ovalipes trimaculatus inhabiting areas comprising a gradient of marine pollution: high, moderate and undetected, in the Nuevo gulf (Patagonia ...
Combining fishers' perceptions, landings and an independent survey to evaluate trends in a swimming crab data-poor artisanal fishery
(Elsevier, 2019-05-01)
The fishery for the swimming crab Ovalipes trimaculatus in the southwestern Atlantic started in 2007, with an average catch of 64.36 t⋅y −1 during the period between 2008 and 2013. The fishery is under an open access regime ...
