Asian Tiger Shrimp Invading the Gulf Coast Waters
A non-native species, Asian tiger shrimp have starting showing up along the Gulf Coast. The concern is that they will eat our shrimp (which are much, much smaller) and that they will eat the food that our shrimp eat, causing our local shrimp to die of starvation. Either way, it would hurt our local shrimp populations. State officials are also concerned that the tiger shrimp will endanger native shrimp species by spreading sickness and depleting food and habitat resources.
It is unclear how the shrimp first ended up in state waters or why their numbers seem to be increasing (one theory is that they came in a ship’s ballast water or escaped from Caribbean aqua farms). The shellfish are native to the West Pacific and are widely farmed in Asia. In other coastal locations fisherman aren’t reporting catching any small tiger shrimp, which makes it unlikely that they’re breeding.
Asian Tiger Shrimp are GIANTS!
The giant tiger prawn is more than just a jumbo shrimp. It’s a huge, hungry and highly invasive species that could pose a jumbo problem for the already embattled Gulf of Mexico ecosystem. A tiger shrimp can grow to the length of a man’s forearm. They are voracious eaters and predators (most native shrimp are scavengers) and are known to eat other shrimp and crabs.
With ever increasing numbers along the gulf coast, scientists are concerned, not just because of the ecological impacts but also due to the fact that tiger shrimp are known to carry at 16 different viruses that can kill other shrimp populations, and even the crab and oysters populations.
We recently discovered a tiger shrimp that we had pulled up with a number of other creatures on one of our recent tour boat excursions aboard The Duke.
It’s too soon to know the scope of the problem, but a reproducing population of tiger prawn in the Gulf could easily be disastrous. The region is already home to a menagerie of invasive species — from tilapia and lionfish to zebra mussels and nutria — and parts of it remain wrecked by the 2010 BP oil spill. An alien predator as big and prolific as the tiger prawn is the last thing such a fragile ecosystem needs.

Injured Kemp’s Ridley Sea Turtle Rescued by the Duke Adventure boat
While on a recent tour, the Duke adventure boat rescued an injured Kemp’s Ridley sea turtle in our drag net. It was discovered that the seat turtle had a hook caught in it’s throat. The Duke Capt. Ray brought the sea turtle on board and contacted the “Share the Beach”, sea turtle rescue volunteer group.Their volunteers met the Duke adventure boat at the Dauphin Island Marina dock to take this injured turtle to the vet. What a great group of volunteers!
It’s such a good feeling when everyone works together! We wish this little sea turtle a speedy recovery!
Capt. Ray said that we very rarely catch any turtles in the net- because of the TED.
What is a TED. TED is a Turtle Excluder Device. Bycatch in shrimp trawls has been a major threat to sea turtles world wide. Shrimp are caught using an otter trawl, a cone-shaped net towed behind a boat that can scoop up everything in its path, including unwanted fish and sea turtles. Sea turtles will likely drown if they are caught in the net.
To reduce this threat, the U.S. required all shrimp trawlers to install turtle excluder devices (TEDs) in their nets starting in 1987. The TED is attached to a shrimp trawling net and is a grid of metal bars that has an opening at the top or bottom, creating a hatch that allows sea turtles and larger fish to escape. Small animals such as shrimp go between the bars and are caught in the end of the trawl. http://marinelife.about.com/od/conservation/g/turtleexcluderdevices.htm
This little guy was big enough to escape, but I think his injury had slowed him down enough that he couldn’t find his way out. If he was a healthy guy this same size, he would almost definitely not have been caught in our net.
This lucky turtle spent the night under the watch of Dauphin Island Sea Lab scientists and went this morning to have surgery at the Institute of Marine Mammal Studies. Thanks to the responsible boat captain of the Duke Adventure boat and the Dauphin Island Sea Lab scientists, this critically endangered sea turtle will be able to go back to the Gulf of Mexico and swim a happy turtle life. Good work DISL! Thanks for all you do! https://www.facebook.com/SouthMobileCountyTourismAuthority
