Rainbow Trout Lifecycle – It Starts With a Tiny Egg

Rainbow Trout Lifecycle - It Starts With a Tiny Egg

The Lifecycle of Goatsbridge Rainbow Trout

 

Brood Stock

We buy our eggs from a specialised hatchery in the USA and the Isle of Man. We kept our own brood stock up to a number of years ago but found it much more convenient to buy them in 6-8 times a year as learnt that it’s better for our farm management. We could only strip eggs once a year and our brood stock took up lots of pond space and lost condition after the process . We buy our eggs from Trout Lodge who are very active in research and development of the best quality eggs possible in terms of disease resistance etc.

We don’t buy the cheapest but we do buy the best.

Rainbow Trout Lifecycle

The eggs arrive by plane into Heathrow airport and are transported by road to Dublin. Unfortunately we can no longer clear these eggs in Dublin which is a pain!

The eggs are striped from the hens(females) and mixed with the milt of the cocks (males) where they fertilise.

They hatch at 300º days i.e. 30 days at 10º Celsius.

They usually arrive at 240º days and will generally hatch 4-5 days later depending on the water temperature here.

The eggs photographed arrived on the 21st of December and they’re shown above just before they hatched 25th January. They’re called ‘eyed ova’ at this stage. Notice one egg has hatched.

Isn’t it fascinating?! Living nature.
