Title
Abstract Background The Nile tilapia (Oreochromis niloticus) is the second most farmed fish species worldwide. It is also an important model for studies of fish physiology, particularly because of its broad tolerance to an array of environments. It i...
In the tilapia species group, the major sex determining factors have been located on Linkage Group 1 (LG1), on a small chromosome (Chr) pair in Oreochromis niloticus, on LG3 (the largest Chr pair) in O. aureus or on both, depending on populations/str...
The present study aimed to develop nondestructive methods to accurately follow the growth of fish larvae and post-larvae. European sea bass (Dicentrarchus labrax) aged 71-100 days post fertilization (dpf; 20-419 mg) and Nile tilapia (Oreochromis nilo...
Nile tilapia has primarily a XX/XY sex determining system but minor genetic factors as well as temperature can override the major factors. Female XX progenies can be sex-reversed into functional males by rearing at high temperatures (>34 °C) from 10 ...
Background: The Nile tilapia (Oreochromis niloticus) is the second most farmed fish species worldwide. It is also an important model for studies of fish physiology, particularly because of its broad tolerance to an array of environments. It is a good...
Anti-müllerian hormone (AMH) is expressed in male embryos and represses development of müllerian ducts during testis differentiation in mammals, birds and reptiles. Amh orthologues have been identified in teleosts despite them lacking müllerian ducts...
Sex in the Nile tilapia, Oreochromis niloticus, is governed by the interactions between a complex genetic sex determination system and the influence of temperature. High temperatures applied during a critical period of sex differentiation can induce ...
Within the tilapia group, the sex determining locus has been located on linkage group 1 (LG1) in Oreochromis niloticus, whereas in O. aureus both LG1 and LG3 are sex-linked. Using specific BAC clones as probes for FISH, LG3 and LG1 have been located ...
Cichlid fish of the Tilapia group are an ideal model for studying sex determination. Sequencing of the Tilapia (Oreochromis niloticus) genome has started in USA and France and genetic and physical linkage maps based on high resolution fingerprints of...
Sarotherodon melanotheron is one of the most euryhaline teleosts able to withstand variations in environmental salinity ranging from freshwater (FW) to 130%0 hyper-saline waters (HSW). Although significant progress has been made in exploring the cell...
