After the Introduction of Yabbyponics, in this article we look further into the reproduction of Yabby (Cherax destructor).
For a better understanding of the behavioral and the biological dynamics involved in this phase of the Yabby life cycle, I split it into stages.
In such a way to clearly frame the ritual the female and male undertake within the mating. As well as the spawning and the following development of the eggs.
In fact, being aware of what it’s occurring in your tanks is the best guarantee of a successful production. In other words, the key information, displayed in the infographics below, will allow you to keep track of the reproductive performance of your stocked Yabbies.
So that you’ll condition your mating tank and farming facility to maximize the reproduction rate of your Yabbies.
Exactly, how we have done since May when we found the first female Yabby carrying eggs. Then, after a week she lost them because of the exceptional low temperature experienced that month.
So that the first clue in possible reproduction issues of the Common Yabby is always water temperature.
Indeed, in the second infographic of the previous article, I mentioned that the optimal water temperature range for mating is 20-25°C (68-77°F).
Moreover, also the amount of hours (≥ 14 hours) of light exposure plays a relevant role in the reproduction of Yabby. Particularly for what concerns spawning induction.
Then, further crucial factors are the age and the size of the female. Since, they are directly correlated with the reach of maturity and the number of eggs produced.
THE GREAT ACCOMPLISHMENTS OF THIS JUNE
As a matter of fact, these latter are affecting the production rate of our Yabbies. Considered that some female Yabbies will start to reproduce next year.
Anyway, yesterday the first two egg batches hatched, while another two females are carrying some eggs at two different stages. Furthermore, we noticed the distinctive behavior of other fertilized female Yabbies.
We’ll real-time witness the development of the larvae produced at My Rivendell Aquaponics Farm. Then, we’ll look into the most complete diet to provide for rearing the juvenile Yabbies.
