Background

Carp represent 40% of the world aquaculture production of fish, crustaceans and mollusks.

In 2015, global culture carp production reached 28.8 million tones, with more than 20 million tonnes were produced in China (link)

According to FAO projections, it is estimated that in order to maintain the current level of per capita consumption, global aquaculture production of carp will need to reach 80 million tonnes by 2050.

Induced spawning in carp fish has traditionally been carried out by a combination of Gonadotropin Releasing Hormone (GnRH) analog, and a non FDA approved dopamine receptor inhibitor, or alternatively by a calibrated carp pituitary extract (CCPE).

Our Innovation

We developed ZAGIN2, a novel spawning agent which utilizes FDA approved materials and is used by intraperitoneal or intramuscular injections.

As such, it has an advantage over commercial spawning agents such as ZAGIN 1 (Drori et al. 1994), Ovaprim, Ovatide which include a non FDA approved component for veterinary use.

Technology

We found a substance that is approved by the FDA for veterinary use and that together with a known compound was found to be a very efficient and spawning induction agent. We named this novel fish feed additive -ZAGIN2.

 

 

The ZAGIN2 is more efficient than ZAGIN1 in terms of increasing the spawning-induction- hormone (LH) levels in female carp.

In comparison to commercially available Zagin 1, hatching was significantly improved using ZAGIN2.

 

Opportunity

We are looking for sponsored research funding in order to test Zagin2 in the lab and at spawning facilities. The Zagin2 will be eligible to receive FDA approval and can be used on fish intended for human or animal consumption - unlike ZAGIN1, Ovaprim and Ovatide which are allowed to be used only on ornamental finfish brood stock.
