Antilisterial Activity of a Carnobacterium piscicola Isolated from Brazilian Smoked Fish (Surubim [Pseudoplatystoma sp.]) and Its Activity against a Persistent Strain of Listeria monocytogenes Isolated from Surubim

Journal of Food Protection, 2005
Data on the prevalence and growth of Listeria monocytogenes in lightly preserved fish products from subtropical and tropical regions are very scarce. Our research describes L. monocytogenes that was detected in 5% of the packages of cold-smoked surubim, a native Brazilian freshwater fish that we analyzed, and shows that the strains isolated were of the

Effect of dietary lipid level on nutritional performance of the surubim, Pseudoplatystoma coruscans

Aquaculture, 2002
Abstract Four diets were formulated to contain a constant protein level (46%) and four different lipid levels (6%, 10%, 14% and 18%). The diets were fed to surubim, a Brazilian native carnivorous freshwater fish. Gross energy of the diets were 4440, 4650, 4840, and 5140 (kcal/kg).

Pharmacokinetic of levamisole in speckled surubimPseudoplatystoma corruscans

Journal of Veterinary Pharmacology and Therapeutics, 2012
Intensification of production systems exposes fish to stress agents, such as poor water quality and crowding, affecting physiological condition of cultured fish, negatively influencing their immune system and increasing susceptibility to microorganism infections (Gopalakannan & Arul, 2006; Sado et al., 2010).

Metabolic and Behavior Changes in Surubim Acutely Exposed to a Glyphosate-Based Herbicide

Archives of Environmental Contamination and Toxicology, 2014
This study examined the effect of glyphosate-based herbicide (Roundup Original), the major herbicide used in soybean crops in Mato Grosso state, at concentrations of 0, 2.25, 4.5, 7.5, and 15 mg L(-1) on metabolic and behavior parameters of the hybrid fish surubim in an acute exposure lasting 96 h. Glycogen content, glucose, lactate, and protein levels

First record of the mating behaviour of the spotted surubim Pseudoplatystoma corruscans in the Uruguay River

Journal of Fish Biology, 2020
AbstractThe spotted surubim Pseudoplatystoma corruscans is a large migratory catfish native to the La Plata and San Francisco basins. Nonetheless, its reproductive dynamics and behaviour remain poorly understood. This brief note provides the first record of the mating behaviour of P. corruscans in natural conditions.

Testicular differentiation and development in South American catfish, surubim, Pseudoplatystoma fasciatum

Journal of Applied Ichthyology, 2019
In the species Pseudoplatystoma fasciatum the males are smaller than females. Thus, the objective of this study was to describe the process of testicular differentiation and provide tools for sex manipulation techniques aimed at improving the productivity of farming of sexually‐reversed females.

Migration and spawning of female surubim (Pseudoplatystoma corruscans, Pimelodidae) in the São Francisco river, Brazil

Environmental Biology of Fishes, 2006
Surubim, Pseudoplatystoma corruscans, is the most valuable commercial and recreational fish in the Sao Francisco River, but little is known about adult migration and spawning. Movements of 24 females (9.5–29.0 kg), which were radio-tagged just downstream of Tres Marias Dam (TMD) at river kilometer 2,109 and at Pirapora Rapids (PR) 129 km downstream of ...

Oocytes of The Endangered Gray Catfish (Surubim-Do-Paraiba) Submitted to Different Conservation Protocols.

Cryo letters, 2021
The gray catfish known as Surubim-do-Paraíba (Steindachneridion parahybae), which is endemic to the Paraíba do Sul river basin, is on the red list of Brazilian fauna threatened with extinction and the cryopreservation of germ cells of this fish is needed in support of conservation.We aimed to assess the effect of storage temperature on S.
