The potential of Hoplias malabaricus (Characiformes: Erythrinidae), a Neotropical carnivore, for aquaculture

open access: yesAquaculture and Fisheries, 2019
We describe key production-related traits of trahira (Hoplias malabaricus), an aquaculture candidate species, in a semi-intensive fish farming system. We quantified growth from hatch through grow-out at two stocking densities and evaluated fillet protein, lipids and fatty-acid content.

Development of microsatellite markers for Hoplias malabaricus (Erythrinidae).

open access: yesGenetics and molecular research : GMR, 2010
We identified 14 microsatellite loci for the wolf fish, Hoplias malabaricus (Erythrinidae), from a genomic shotgun library. Twenty-five primers were designed, and 48 individuals of H. malabaricus from four localities of northwest Goiás, in central Brazil, were genotyped to characterize the polymorphism at each locus.
