Hoplias aff. malabaricus Bloch, 1794 (Characiformes: Erythrinidae) parasites [PDF]

Arquivos do Instituto Biológico, 2018
ABSTRACT: Aquatic organisms are a subject of great interest because of their nutritional value and their high availability as human food. As a result, an increasing number of studies are being conducted on potentially harmful aquatic organisms such as aquatic parasites that compromise host health, as well as affect public health by zoonosis.

DNA Barcoding unveils cryptic lineages of Hoplias malabaricus from Northeastern Brazil [PDF]

Brazilian Journal of Biology, 2021
Abstract The trahira or wolf fish - Hoplias malabaricus- is a valid species, although recent cytogenetic and molecular studies have indicated the existence of a species complex. In this context, the present study analyzed the mitochondrial COI marker to determine the levels of genetic diversity of specimens from the Brazilian state of Maranhão, and ...

Addressing challenges in Hoplias cf. malabaricus (Characiformes: Erythrinidae) taxonomy and distribution in Southern Brazil with otolith shape analysis

Neotropical Ichthyology
Species of Hoplias malabaricus complex group are widely distributed in most Neotropical drainages. Some species are cryptic and difficult to identify and delimit because many morphological characters are highly homoplastic and variable.

Metabolismo de rutina de Hoplias malabaricus malabaricus (Bloch, 1974) (Osteichthyes, Erythrinidae) [PDF]

Revista Brasileira de Zoologia, 1982
The routine metabolism of Hoplias m. malabaricus in relation to weight, at 3 different experimental temperatures (15, 20, 30oC), through oxygen consumption in confinement and in the absence of external stimuli was studied. The metabolic index (mg O2/g.h) and the intensity of metabolism (mg O2/g.h), for each temperature, were obtained.

Hematologic and hepatic responses of the freshwater fish Hoplias malabaricus after saxitoxin exposure [PDF]

Toxicon, 2013
The bioaccumulation of saxitoxins (STX) in the trophic chain, mainly in freshwater, are not completely known. This work aimed to elucidate the effects of STX on Hoplias malabaricus through trophic bioassay. The fish were fed once every five days with Astyanax sp.
