Reproduction in Osteichthyes - Reference Module in Life Sciences

Currently, >33,000 fish species are recognized. This is close to 50% of all known vertebrate species. Osteichthyes is a taxonomic group of fishes that includes the ray-finned fish (Actinopterygii) and lobe-finned fish (Sarcopterygii). Of these, the Teleostei, or the modern bony fishes in the class Actinopterygii are the majority and are represented by ~27,000 species.

Growth hormone overexpression disrupts reproductive status through actions on leptin

Growth and reproduction are closely related. Growth hormone (GH)-transgenic common carp exhibit accelerated growth and delayed reproductive development, which provides an amenable model to study hormone cross-talk between the growth and reproductive axes. We analyzed the energy status and reproductive development in GH-transgenic common carp by using multi-tissue RNA sequencing, real-time-PCR, western blotting, ELISA, immunofluorescence and in vitro incubation.


The long-term objective of the TEAMENDO research program is to understand how the brain and pituitary transduce environmental and physiological signals into changes in reproductive function.
