The dingy waters of Cow Bayou wind through the southernmost reaches of the Pinewoods and empty into the coastal marsh near the mouth of Sabine Lake.
The upper reaches north of FM 105 are lined with hulking cypress trees and are a favorite destination of locals running trotlines for channel cats and the occasional bass fishermen
Yet somehow in 2014, a pair of bottlenose dolphins found their way into this area.
One was tragically killed by poachers and the other, a younger male, got disillusioned and found itself unable to find its way back to more saline waters. Eventually too much exposure to fresh water will kill dolphins.
A crew from the Texas Marine Mammal Stranding Network, Sea World San Antonio, Texas Parks & Wildlife Department, Louisiana Department of Wildlife and Fisheries, the Orange County Sheriff’s Department and NOAA rescued that dolphin.
After deemed releasable, the dolphin was brought to Sea Rim State Park and put into the surf.
“It’s an incredible feeling to get to release a dolphin like that. Once the designation is given to us that an animal can be released we are always relieved because that is certainly the option we desire,” said Chris Bellows former VP of Zoological Operations at Sea World San Antonio who served at the time of this release.
But some dolphins are not able to be released.
“When a dolphin or any marine mammal has been rescued by a federally authorized organization the first goal is to get that animal back out to the wild. Sometimes that can’t happen. NOAA receives information from veterinarians and care givers and if the recommendation is to provide long term care NOAA makes that decision,” Bellows said.
“Once the decision has been made to care for an animal for the rest of its life the goal is to place it at a facility with like species. NOAA sends out a questionnaire to these facilities asking if they would be willing to care for the animal. They also check to make sure certain criteria is met. At SeaWorld San Antonio we currently have five dolphins that were placed with us by NOAA. Our goal is always to get the animals back out to the wild but we will provide a home for those that can’t be returned.”
Me and my wife Lisa got to meet several of these amazing animals and were blown away by the level of care and attention given them.
While visiting Sea World San Antonio we also learned of a manatee that ended up in a power plant canal in Trinity Bay. Coastal fishermen frequently see dolphins but very few have seen manatees on the Texas coast although they seem to be moving into the state with greater frequency.
The truth is Gulf waters are rich in marine mammals and although many of them are rarely seen by the public their conservation is important to the overall health of the Gulf ecosystem.
According to NOAA there are 28 different species of marine mammals known to occur in the Gulf of Mexico. All 28 species are protected under the Marine Mammal Protection Act (MMPA) and six are also listed as endangered under the Endangered Species Act (ESA) (sperm, sei, fin, blue, humpback and North Atlantic right whales).
Of the six ESA-listed whales, only endangered sperm whales are considered to commonly occur. There according to NOAA a resident population of female sperm whales in the Gulf of Mexico, and whales with calves are sighted frequently.
Cuvier’s beaked whales are elusive and rarely seen at the surface, which is why their population status is unknown. These whales vary in coloration from rusty-brown, dark gray, or tan. They prefer deep water, avoid shallow coastal areas, and are known to travel in groups of two to seven.
Bottlenose dolphins inhabit the Gulf of Mexico year- round. They are blue-gray with lighter sides and bellies and have a robust body and head. This species is the most commonly observed dolphin in nearshore waters, and travel alone or in groups up to 20. These are the dolphins seen around ferries and in our bay systems.
Atlantic spotted dolphins prefer tropical to warm-temperate waters over the continental shelf, edge, and upper reaches of the slope. These dolphins have variable spotting. They are very active at the surface and often breach while feeding. Group size is usually between 5-15.
Risso’s dolphins are typically found around the continental shelf edge and steep upper sections of the slope. They are light gray and often exhibit extensive scarring. These dolphins travel alone or in groups of up to 100 and may be observed with other species.
No one enters these animals domain more than fishermen and in many cases anglers have helped locate and monitor injured marine mammals.
Anglers have been at the forefront of the conservation world with groups like the Coastal Conservation Association working heavy with sport fish and habitat but have also been very interested in aiding all aquatic species.
Marine mammals are some of the most interesting creatures in the world and if we open our eyes and pay just a little more attention we might just come across a rarity or get a big surprise.
I will never forget the first time I saw a pink albino dolphin near Lake Calctsieu in Louisiana and saw a beaked whale while fishing 80 miles offshore in a party boat out of Galveston. It’s our duty to makes sure these creatures can thrive in the waters that we know and love.
