Short periods of food restriction do not affect growth, survival or muscle development on pacu larvae
(Aquaculture, 2015-01-20) [Artigo]
The present study evaluated the effects of different fasting periods on survival rate, growth, muscle development and compensatory growth in pacu (Piaractus mesopotamicus) larvae. In Phase I, larvae (5 days post hatching, ...
The basement membrane and the sex establishment in the juvenile hermaphroditism during gonadal differentiation of the Gymnocorymbus ternetzi (Teleostei: Characiformes: Characidae)
(Anatomical Record (hoboken, N.j. : 2007), 2015-09-19) [Artigo]
Although there are several studies on morphogenesis in Teleostei, until now there is no research describing the role of the basement membrane in the establishment of the germinal epithelium during gonadal differentiation ...
Effects of re-stripping on the seminal characteristics of pacu (Piaractus mesopotamicus) during the breeding season
(General And Comparative Endocrinology, 2015) [Artigo]
Seminal characteristics in teleost fish with an annual reproductive period, such as pacu (Piaractus mesopotamicus), may vary during the breeding season. The sperm formed before the beginning of the spawning period may be ...
New Insights into Karyotypic Relationships Among Populations of Astyanax bockmanni (Teleostei, Characiformes) of Different Watersheds
(Zebrafish, 2015-04-01) [Artigo]
The fish constitute about 50% of all vertebrates, including a wide morphological and biological diversity, where the genus Astyanax is the most common and diverse, as described in virtually all freshwater environments. By ...
Aloe vera bathing improved physical and humoral protection in breeding stock after induced spawning in matrinxa (Brycon amazonicus)
(Fish & Shellfish Immunology, 2015-07-01) [Artigo]
In this study, we show that induced spawning causes stress, an intense loss of epithelia and immunosuppression, decreasing physical and humoral protection in fish, effects that were prevented or improved in fish bathed ...
Steelhead trout Oncorhynchus mykiss metabolic rate is affected by dietary Aloe vera inclusion but not by mounting an immune response against formalin-killed Aeromonas salmonicida
(Journal Of Fish Biology, 2015-07-01) [Artigo]
The oxygen consumption (MO2) of two groups of 10 degrees C acclimated steelhead trout Oncorhynchus mykiss was measured for 72 h after they were given a 100 mu l kg(-1) intraperitoneal injection of formalin-killed Aeromonas ...
