O presente trabalho teve como objetivo elaborar um hidrolisado proteico de carne de palometa (Serrasalmus spilopleura) por via enzimática utilizando a enzima Alcalase, bem como realizar a caracterização físico-química e avaliar suas propriedades tecno-funcionais. O grau de hidrólise (GH) do hidrolisado proteico de palometa foi 17,4% e conteúdo proteico

Double cone mosaic pattern in the retina of larval and adult piranha,Serrasalmus spilopleura
Experientia, 1992The mosaic pattern of double cones of retinas in larval and adult piranha,Serrasalmus spilopleura, was examined. Samples from two habitats in the same reservoir, characterized by different light conditions, were examined. The same square pattern was found in all sampled retinas indicating that, for this species, there is no apparent relation between ...

The water hyacinth, Eichhornia crassipes, plays an important role in the early life of the piranha, Serrasalmus spilopleura in southeastern Brazil. Larvae and early juveniles are found by both day and night among the roots of this free floating waterweed, thus gaining shelter, a rich foraging place, and potential rafting dispersal. Piranha larvae up to

Reproduction in female Serrasalmus spilopleura (Characiformes, Characidae) from the Itumbiara reservoir (18°28′ S, 48°36′ W), Paranaiba River, Brazil, was examined with emphasis on the relationship between condition factors and coelomic fat, the annual reproductive cycle and the unusual dynamics of its sexual maturity. The condition factor and coelomic

The morphophysiological changes that occur during oocyte primary growth in Serrasalmus spilopleura were studied using ultrastructural cytochemical techniques. In the previtellogenic oocytes endoplasmic reticulum components, Golgi complex cisternae and vesicles, lysosomes, multivesicular bodies and some electron-dense vesicles react to acid phosphatase (

The freshwater fish Serrasalmus spilopleura (piranha) has a continuous type of reproduction; gametes are constantly produced and released during the reproductive cycle. The testes do not undergo seasonal morphological changes but exhibit two constant regions throughout the year: the medullar region (involved with spermatogenesis) and the cortical ...

AbstractThe follicular epithelium and theca of oocytes in Serrasalmus spilopleura differentiates during the initial primary growth phase. The follicular cells are squamous and the thecal cells are disposed in two layers. During the secondary growth phase, follicular cells become cuboidal, acquire characteristics typical of protein‐ or glycoprotein ...

Regression analysis of log10 upper and lower caudal lobe area (whole ‘uncropped’ caudals) against log10 standard length for ten prey species of the piranha showed significant differences in both slope and intercept for only one species (Astyanax fasciatus) although intercepts alone were significantly different for two others (A.
