Ontogeny of the digestive system and the profile of proteases in larvae of cachara (Pseudoplatystoma reticulatum Siluriformes: Pimelodidae) and its hybrid (Pseudoplatystoma corruscans × Pseudoplatystoma reticulatum)
(2021-09-01)
The development of the digestive system and digestive proteases was studied in cachara (Pseudoplatystoma reticulatum) and its hybrid (P. reticulatum × Pseudoplatystoma corruscans) during the first 25 days after fertilization. ...
Fertilização e desenvolvimento embrionário: Morfometria e análise estereomicroscópica dos ovos dos híbridos de surubins (pintado, Pseudoplatystoma corruscans x cachara, Pseudoplatystoma fasciatum)
(2007-01-01)
This study aimed to analyze the morphometry of hybrids' eggs under stereomicroscopy. The induced reproduction was carried out in specimens of pintado's females (P. corruscans) and cachara's males (P. fasciatum) from Cepta ...
Cytogenetic characterization of F1, F2 and backcross hybrids of the Neotropical catfish species Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum (Pimelodidae, Siluriformes)
(Sociedade Brasileira de Genética, 2012-01-01)
The cytogenetic characteristics of Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum and their F1, F2 and backcross hybrids were assessed by using chromosome banding techniques. The diploid number of 56 chromosomes ...
COMPARISON BETWEEN TWO FEEDING RATES AND THREE FEEDING FREQUENCIES FOR HYBRID SURUBIMS REARED IN CAGES
(Univ Fed Rural Semi-arido-ufersa, 2018-07-01)
This study evaluated the effects of feeding frequency and feeding rate on productive performance of hybrid surubims reared in cages with automatic feeding. Three feeding frequencies (6, 12 and 24 meals day(-1)), and two ...
Abundância natural do isótopo estável de carbono (13C) de alguns itens alimentares e sua contribuição no crescimento de juvenis de pintado, Pseudoplatystoma corruscans (Agassiz, 1829) (Osteichthyes, Pimelodidae)
(2002-12-01)
The aim of this study is to determine the natural abundance of carbon stable isotope (13C) of some food components and determine its contribution to the pintado juvenile growth, in laboratory conditions. 150 fishes were ...
Comparación del Desarrollo Embrionario de Piaractus brachypomus (Serrasalmidae) y Pseudoplatystoma sp. (Pimelodidae)
(Sociedad Chilena de Anatomía, 2010)
Fatty acids as a tool to compare cachara (Pseudoplatystoma reticulatum) (Siluriformes: Pimelodidae) and hybrid (Pseudoplatystoma corruscans x Pseudoplatystoma reticulatum) larvae during early development
(SPRINGERDORDRECHT, 2012)
In this study, we investigated the physiological alterations during ontogeny for cachara (Pseudoplatystoma reticulatum) and their hybrid larvae (Pseudoplatystoma corruscans x P. reticulatum) using lipids and fatty acids ...
Brazilian catfish parasitized by Epistylis sp. (Ciliophora, Epistylididae), with description of parasite intensity score
(2013-01-01)
The determination of mean intensity of parasitism for colony-forming sessile protozoan such as Epistylis has been a great problem in parasitological studies. Some alternatives have been proposed by researchers for laboratory ...
Isolation and characterization of microsatellite loci in Pseudoplatystoma corruscans (Siluriformes : Pimelodidae) and cross-species amplification
(Blackwell Publishing, 2005-09-01)
A total of five polymorphic microsatellites loci from Pseudoplatystoma corruscans were isolated and characterized. A population survey involving 43 specimens resolved a large number of alleles (range seven to eight among ...
