Project ID : 24-2011-2633
Description of the technology
Enables hormonal manipulation of the reproductive cycle
Agriculture, Aquaculture, Fish Culture, Animal Sciences, Mariculture
Preliminary proof of concept; ongoing research
United States patent application filed.
The endocrine regulation of vertebrate reproduction is achieved by the coordinated actions of several peptide neurohormones.
With fish being an important food source, there is a need to better understand how to increase their reproductive capabilities.
However, in fish, it was found that the same genes did not appear to be directly involved in the initiation of the reproductive cycle as was shown for mammals.
Following the identification of Neurokinin B (NKB) genes in fish, we developed analogs that enable manipulation of hormonal activity and reproductive cycles. Antagonists will enable the inhibition of reproduction of farmed fish.
The new analogs will help to obtain successful spawning and improved egg quality in farmed fish, especially of fish species that are late-maturing.
The new antagonists will help to prevent early sexual maturation of farmed fish that ends up in small size cultured fish.
Simple and low cost method
Unlike other agents that are in the market, the new agent will enable the control of different stages of fish reproduction.
The novel agents will be appropriate for both males and females.
These analogs will fit different species of fish.
Seeking an industrial partner to commercial this technology and further funding of research.
The method (inject fish with hormones) been used today is expensive.
This novel agent will be able to either facilitate or halt fish reproduction.
Can fit many fish species, at different stages.
