Age and growth of Hypophthalmus edentatus (Spix), (Siluriformes, Hypophthalmidae) in the Itaipu Reservoir, Paraná, Brazil [PDF]

Revista Brasileira de Zoologia, 2003
Age and growth of Hypophthalmus edentatus (Spix, 1829) (Siluriformes, Hypophthalmidae) was determined. Data were collected from December 1983 to November 1984 and from April 1997 to March 1998 in the Itaipu Reservoir. To evaluate reading consistency, it was analyzed the coefficient of variation of the total length for each annulus observed in the ...

Otimização da desidratação osmótica de filés de mapará (Hypophthalmus edentatus) através da metodologia de superfície de resposta [PDF]

Ciência e Tecnologia de Alimentos, 2008
A desidratacao osmotica de files de mapara tem sido utilizada como pre-tratamento antes da secagem e refrigeracao de alimentos como um meio de reduzir a umidade dos produtos. O objetivo do trabalho foi otimizar a transferencia de massa ocorrida durante a desidratacao osmotica de mapara atraves da metodologia de superficie de resposta.

Morphological description of larvae of the Mapará Hypophthalmus edentatus (Spix) (Osteichthyes, Hypophthalmidae) in the Itaipu reservoir (Parana River, Brazil) [PDF]

Revista Brasileira de Zoologia, 1998
The ontogenetic aspects of larvae of Hypophthalmus edentatus (Spix, 1829) from the ichthyoplankton samples collected in the Itaipu reservoir between March 1988 and April 1990 were analysed. Sample were caught by 0.5 mm mesh conic-cylindrical plankton net. Larvae of H.

Ontogenetic changes in the food items assimilated byPlagioscion squamosissimus(Perciformes: Sciaenidae) andHypophthalmus edentatus(Siluriformes: Pimelodidae) [PDF]

Journal of Freshwater Ecology, 2011
In order to identify the ontogenetic changes in the food items assimilated by the larvae of Plagioscion squamosissimus and Hypophthalmus edentatus, we analyzed the stomach content and the nitrogen isotopic value (δ 15N) from the larvae. Samplings were performed monthly, from October 2002 to March 2003, and October 2003 to March 2004 in the subbasin of ...

Effects of light-dark cycle on the spatial distribution and feeding activity of fish larvae of two co-occurring species (Pisces: Hypophthalmidae and Sciaenidae) in a Neotropical floodplain lake

Brazilian Journal of Biology, 2018
Most studies on mechanisms regulating fish larvae processes have focused on assessing the isolated effects of food distribution and feeding behavior. However, in natural ecosystems, fish larvae may strongly interact with zooplankton organisms in an array

Endoparásitos con potencial zoonótico en cinco especies de peces de consumo comercializados en el puerto "Don José" - Iquitos [PDF]

, 2022
The objective of the present study was to identify the species of endoparasites with zoonotic potential in five species of commercialized fish in the “Don José” port: Plagioscion squamosissimus (Heckel, 1840), Pseudoplatystoma punctifer (Castelnau, 1855);
