Rearing temperature induces changes in muscle growth and gene expression in juvenile pacu (Piaractus mesopotamicus)
(Comparative Biochemistry and Physiology B: Biochemistry & Molecular Biology, 2014-03-01) [Artigo]
Pacu (Piaractus mesopotamicus) is a fast-growing fish that is extensively used in Brazilian aquaculture programs and shows a wide range of thermal tolerance. Because temperature is an environmental factor that influences ...
Quantitative expression of myogenic regulatory factors MyoD and myogenin in pacu (Piaractus mesopotamicus) skeletal muscle during growth
(Micron, 2010-12-01) [Editorial]
Skeletal muscle growth is regulated by differential expression of myogenic regulatory factors (MRFs). We evaluated hyperplasia, hypertrophy and quantitative expression of MRFs MyoD and myogenin in 45, 90, 180, and 400 days ...
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, ...
Genetic Identification of F1 and Post-F1 Serrasalmid Juvenile Hybrids in Brazilian Aquaculture
(PLOS ONE, 2014-03-03) [Artigo]
Juvenile fish trade monitoring is an important task on Brazilian fish farms. However, the identification of juvenile fish through morphological analysis is not feasible, particularly between interspecific hybrids and pure ...
Male Gonadal Differentiation and the Paedomorphic Evolution of the Testis in Teleostei
(Anatomical Record-advances In Integrative Anatomy and Evolutionary Biology, 2014-06-01) [Artigo]
Testis differentiation from representatives of the Otophysi (Cyprinus carpio), Percomorpha (Amatitlania nigrofasciata), and Atherinomorpha (Poecilia reticulata) was comparatively described. In the undifferentiated gonad ...
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 ...
