“My home is the open sea, where stars shine brighter & my souls is free”
Once or twice a year a remarkable thing happens right here in the Bay. The Bayworld team work hand in hand with the Stampede crew, clearly a match made in heaven and they have allowed us to be the stars! The Bayworld team; Mike, Akhona and Ruth have not only dedicated their lives to the cause but work tirelessly to rehabilitate injured sea turtles. If you weren’t aware, turtles are endangered, which makes their work all the more important! Robbie, and his crew Mike and Jamie who man Stampede, a luxury 38ft Supercat, have volunteered their time and catamaran to transport these magnificent turtles back to freedom.
April 17thwas bitter sweet, Oliver a 10-year-old Loggerhead turtle and Aloe, a 4-year-old female Green Turtle were ready for release. Oliver had been rescued from the East London Zoo and Aloe washed up in the Jeffrey’s Bay surf, unable to dive. Both had done their time at Bayworld, fighting for survival with the assistance of their rehabilitation team. Akhona will tell you that Oliver had a lot of fight left in him and he wasn’t scared to show off his sharp beak and extremely strong jaw – that boy could bite, dictating that he was ready for open seas. Aloe on the other hand suffered a large air bubble under the skin which wasn’t allowing her to dive or submerge himself under water…As sea turtles are air breathing reptiles, they need to surface to breathe. Sea turtles can hold their breath for several hours, depending upon the level of activity. A resting or sleeping turtle can remain underwater for 4-7 hours. However, a stressed turtle, entangled in fishing gear for instance, quickly uses up oxygen stored within its body and may drown within minutes. They do however forage (feed) under water, and if they can’t submerge themselves, they will starve. The team had worked with Aloe for 4 months, aiding in her recovering and today was release day...Any animal lover understands the emotional attachment when caring for an injured creature. You are delighted in their rehabilitation but saddened by the goodbye…
Researchers track sea turtles through using satellite telemetry. A small transmitter is attached to the turtle’s carapace (on hard shelled species). The transmitter emits signals of information to an orbiting satellite when the turtle surfaces to breathe or bask. The information in the signals is sent to receiving stations on Earth, and is then sent to the researcher’s computer as a dataset. This data provides information on the turtle’s location, number of dives during the last day, length of the most recent dive, water temperature, etc. Data, received over a period of time, allows for tracking a turtles movement, patterns and swimming speed. Tracking has provided important information on migration routes between breeding and foraging (feeding) habitats. The time length of tracking depends upon how long the device remains on the turtle and on battery life. Tracking usually continues for 6-10 months, although cases have been reported exceeding 2 years. After about two years, the transmitters fall safely off the turtles. Oliver received a transmitter to allow researchers to keep track of him for a little while.
After loading the turtles, we set off for St Croix Island. The turtles were stressed, contained in boxed crates with damp towels, anxiously awaiting their fate. Knowing they could smell freedom made the journey that much longer. The saving grace is that Stampede is built with slim hulls which enable comparatively high speeds with relatively low power, extraordinary comfort and stability when compared with other boat configurations. These turtles couldn’t have asked for a smoother ride! On route we were greeted by a 3km stretch of Bottle Nose Dolphin, frolicking in the waves. A serenading of sorts, like these sentient beings were aware of the freedom about to be bestowed on their two long lost friends…a remarkable experience.
Sea turtles are part of two ecosystems, the coastal system and the marine system. If sea turtles became extinct, both the marine and coastal ecosystems would be negatively affected. And because humans utilize the marine ecosystem as a natural resource for food and use the coastal system for a variety of activities, a negative impact to these ecosystems would negatively affect humans. Sea turtles, especially green sea turtles, are one of the very few animals to eat sea grass. Like normal lawn grass, sea grass needs to be constantly cut short to be healthy and help it grow across the sea floor. Sea turtles act as grazing animals that cut the grass short and help maintain the health of the sea grass beds. Sea grass beds are important because they provide breeding and developmental grounds for many species of fish, shellfish and crustaceans. Over the past decades, there has been a decline in sea grass beds. This decline may be linked to fewer numbers of sea turtles grazing. Without sea grass habitats, many of marine species would be lost. All parts of an ecosystem are important. If you lose one, the rest will eventually follow.
Keep in mind that Turtles are opportunistic feeders, meaning they will eat just about anything, sort of like a billy goat. Unfortunately, it is nearly impossible for a turtle to break-down synthetic material once it is ingested, and very often it will cause an intestinal blockage, called an impaction. Of course, a turtle has little chance of eliminating the impaction on its own in the wild and this condition will usually lead to starvation. This is one reason why we need to keep track of our trash and make sure it is properly disposed of.
We found a safe spot just off the island, each person on board had their own moment of silence as the process of release was started. It’s not an easy thing to lift a 35kg turtle over board. Surprisingly, neither turtle put up a fight! It was one of the most liberating experiences to watch. Robbie and Akhona balanced themselves at the edge of the boat, handling each turtle carefully, until they could reach the water. Watching them approach the water, becoming submerged and swimming to freedom felt like a wave crashing over you, cleansing the depths of your soul. We did it, they were free! Today we were privileged enough to walk with two turtles, even if just for a little while – and we were made aware that this experience will forever change us!
