Growth hormone secretion is classically modulated by two hypothalamic hormones, growth hormone-releasing hormone and somatostatin. A third pathway was proposed in the last decade, which involves the growth hormone ...

This review concerns the phenomenon of heterogeneous growth (Het-G) in fish. Het-G is characterized by different growth rates between conspecifics. Although genetic determination on Het-G is recognized, grouping increases ...

Background/Aims: There are many controversies regarding side effects on craniofacial and extremity growth due to growth hormone ( GH) treatment. Our aim was to estimate GH action on craniofacial development and extremity ...

Seasonal growth of G. maculatus in Tierra del Fuego, at the southern limit of its distribution, would be explained by the variation of extrinsic factors, and experiments of fasting under summer conditions would allow ...

Increase in heterogeneous growth as a result of grouping in the Nile tilapia, Oreochromis niloticus (L.), is presumed to be partially promoted by the social stress imposed by the dominant fish on the subordinates. Such ...
