Did Scientists Find The Key To Restoring The Snook Population?
By: Joseph Simonds on May 1, 2019
If you’ve ever heard your reel scream…
Or felt your rod double over when a snook hits your bait…
There’s a very high chance that snook is your favorite species to target.
They’re big, strong, and acrobatic.
It’s no wonder they have a cult-like following.
But they’re also sensitive.
In 2010 the snook population was decimated by a cold snap.
And last year they got hit badly with red tide.
But scientists may have made a big breakthrough in restocking the snook population.
Are Probiotics The Key To Restoring Snook?
Since up to 99% of larvae die in some marine fish species, larval mortality is a huge bottleneck in rearing fish.
To try to increase the larval survival rate, here’s what they did…
They studied three groups:
- Control group that received no probiotics
- Test group that received probiotics in the water and their food
- Test group that received probiotics in the water alone
What they discovered was huge.
Snook that received probiotics in their water and food had a 2.5 times greater chance of survival on average!
And this wasn’t a small test.
They tested hundreds of thousands of snook larvae.
What’s more, the snook that received the probiotic had an increased survival rate of 20% a week after they went through a simulated transport.
So not only are more snook babies surviving in the lab, but after going for a little car ride (to simulate them getting dropped off in your honey hole), more snook are surviving.
Science for the double win!

What does this mean?
When snook die from cold snaps or bouts of red tide, facilities like the Mote Marine Laboratory have more snook babies to replenish the stock.
And not only do they have more snook babies to replenish the stock, but these babies have a 20% higher chance of surviving.
This is very encouraging for future snook populations.
Although we are still struggling with red tide, and the occasional cold snap can hurt our snook stock any given winter…
The good news is that scientists may have found a way to better replenish the snook population.
With a 2.5x increased larval survival rate and 20% higher chance of surviving after transport, probiotics are making snook’s future look just a little brighter in these tough times for the environment.
