I also dont understand why some people get more upset by captive whalesharks than they do about captive dolphins. Why not buy the shark from the Fishermen and then release it ? The situation in Taiwan with the whale sharks was that they are allowed to catch a very limited number of them per year, and in this case the aquarium paid for four of those sharks that had been caught. Okinawa Churaumi Aquarium was the first to have whale sharks in captivity in 1980. If keeping some creatures in captivity helps educate people so that they help save all the endangered places and creatures, then it is a necessary price to pay. The alternative was that they would simply be eaten- in which case they would be dead and not educating the public about sharks. Despite feeding almost exclusively on plankton, the whale shark is one of the most peaceful creatures in the ocean. There has been much proof on top of dolphins in captivity being harmed, distressed and even dying through the trauma of capture and also other problems and consequences that people just do not want to face up to. Saying the best care available isnt tricky. Despite the fact that scientists estimate that whale sharks can live to be 60 years old, the true lifespan of these gentle giants is unknown. I thought he didnt really give an explanation: they had a theory, but he didnt connect it to the autopsies. The other benefit is always financial who would donate enough money to fund all the research that is needed? (Plus, I never would have seen them.) [19][20], The complete and annotated genome of the whale shark was published in 2017. Note: This ethical debate is a heavily modified re-post of an earlier ethical debate on the old site, which can be found here. The animal rights activists like to say these charismatic captives are lonely, swimming in their own urine, cramped swimming in a bathtub, etc. These whale sharks are better off where they are. The sharks are now alive, healthy, and being used to educate the public about sharks. Although there is always the questionable topic of it being safe to hold these animals outside of their natural habitats I do feel it is sometimes necessary to take a few and maintain them in aquariums to allow people the ability to see and understand the purpose of the species in person. As such, the conditions of captivity may be too restrictive for the whale sharks natural behavior, leading to physical and psychological distress. Yes, its sad that two of the whale sharks died, but does that mean it was a terrible idea to have these amazing creatures in captivity in the first place? Under these circumstances, there is little evidence the Georgia Aquarium is at fault for housing these incredible Sharks. But the Atlanta aquarium isn't the first place to struggle with keeping whale sharks alive in captivity. Another thing I would like to address is the money factor. Education is a hard one, as i said i would love to show my daughter the sharks but i can not shake the bad taste in my mouth. What happens to them after, whether they are sold at the fish market or placed in an aquarium, is irrelevant from a fisheries management perspective. Unless evidence was found a la The Cove that whale sharks are so unhappy in captivity or people would stop freaking finning sharks into extinction, I think they should probably stay where they are. How big are whale sharks? Orcas kept in captivity are thought to live shorter lives than those in the wild; however, this is open to scientific debate. When confined, they are prevented from carrying out natural behaviors, which include roaming up to 100 miles per day, hunting live prey, and interacting with their pod mateswho also suffer when pod members are removed. A Whale Shark by Any Other Name", "A note on the whale shark Rhincodon typus Smith, stranded off Mangalore", "Whale Sharks Have Tiny Teeth on Their Eyeballs", "Draft sequencing and assembly of the genome of the world's largest fish, the whale shark: Rhincodon typus Smith 1828", "Wound-healing capabilities of whale sharks (Rhincodon typus) and implications for conservation management", "Asymptotic Growth of Whale Sharks Suggests Sex-Specific Life-History Strategies", "Annual Bands in Vertebrae Validated by Bomb Radiocarbon Assays Provide Estimates of Age and Growth of Whale Sharks", "A review of the biology, fisheries and conservation of the whale shark Rhincodon typus", "Size and maturity status of the whale shark (Rhincodon typus) at Ningaloo Reef in Western Australia", "How large is the world's largest fish? Not to be redundant, but one must consider the small percentage of these creatures that are being put on display for the greater good of the entire species. That would be a bad idea and there is no telling how many whale sharks are dying out in the wild, but they are. [11][51][52] The eggs remain in the body and the females give birth to live young which are 40 to 60cm (16 to 24in) long. Who cares whether a whale shark is gentle?

Having a dive program available at an aquarium is a great learning opportunity, but I think it should be limited to those with scuba diving certification; otherwise, the program would be too risky, both for the shark and the diver. Still, scientists have yet to confirm this behavior. Show all. The mystery of the whale shark and its incredible longevity has fascinated scientists for centuries. Taking a potential breeder from the wild removes not only one whale shark from the population, but also the offspring she could produce in her natural environment. [26][9], In 1934, a ship named the Maunganui came across a whale shark in the southern Pacific Ocean, rammed it, and the shark became stuck on the prow of the ship, supposedly with 15ft (4.6m) on one side and 40ft (12.2m) on the other, suggesting a total length of about 55ft (17m). I dont think a fish, even a big fish such as a whale shark has as much of an intellectual sense as say a monkey. And the sharks were saved from their track to a white platted dinner? It was one of the largest gatherings of whale sharks recorded. Is it actually that powerful, having seen it? Too many sea creatures are being fished from coral reefs and our oceans to fill the growing demand to see wild animals up close, through pet shops, tropical fish collections and aquariums. The whale shark was fed with a tube after it seemed to lose its appetite over a period of months last year, said Robert Hueter, director of the center for shark research at the Mote Marine Laboratory in Sarasota, Fla., who participated in the examination of the shark's body. The tail has a larger upper lobe than the lower lobe (heterocercal). The one thing that I dont agree with about holding animals in captivity is the fact that in most cases we hinder them from their natural instincts. That being said, we must be careful about assigning human emotion to these animals (the same goes for captive killer whales and dolphins). [40] Tracking devices have shown that the whale shark displays dynamic patterns of habitat utilization, likely in response to availability of prey. New research shows there is no difference in life expectancy between killer whales born at SeaWorld and a well-studied population of wild killer whales. The aquarium certainly wouldn't acquire sharks in this way if it effectively encouraged MORE fishing for whale sharks. The more interesting question than how much we need to know about an animal's fundamental needs in order to keep it alive, is whether we should keep it in captivity in the first place. Instead, it swims to force water across its gills. Keeping animals in captivity is a touchy subject. These gentle marine giants roam the oceans around the globe, generally alone. Several of these were already weak from the capture/stranding and some were released,[80] but initial captive survival rates were low. Toggle navigation. I do believe that the whale sharks as a species benefit from the captivity of a few individuals. Holding a whale shark in a highly constraining artificial environment, where it is unable to feed or swim long distances naturally, has been implicated in the early death of every whale shark known to have been held in captivity in other countries. Sightings confirmed that the whale sharks were unable to avoid the oil slick, which was situated on the surface of the sea where the whale sharks feed for several hours at a time. Scientists estimate that the Megalodon would need to consume 98,000 kcal daily to maintain its mass thats 49 times more energy than a human being. NO. My only guess is that they dont know much about the biology of the critters. Leaf-eating monkeys were notoriously short-lived, but animals like the proboscis monkey were such a hit with zoo-goers that replacements for the dying animals were always sought. The Fin whale has an average lifespan of 60 - 100 years. [83] This is unusual because of the comparatively long transport time and complex logistics required to bring the sharks to the aquarium, ranging between 28 and 36 hours. As for calling them "gentle" or calling white sharks "vicious," this is neither here nor there. On the topic of the deaths of the two sharks, I fail to see how a parasite treatment would cause peritonitis, as Im unfamiliar with whale shark medicine (crazy, huh?). I believe that it is acceptable for whale sharks to be held in captivity, as long as they are well taken care of and not showing any signs of distress; especially if keeping sharks in captivity allows people to study them and help the population in the wild. Whale sharks eat microscopic plankton. Whale sharks in captivity face numerous challenges that make it difficult to acclimate and survive.

Furthermore, the aquarium has specialized feeding requirements and has a large tank, making it possible for whale sharks to swim around in the water. 3. Ideally, the animals would rotate back to the wild (not Taiwan!). [33][34], Scott A. Eckert & Brent S. Stewart reported on satellite tracking of whale sharks from between 1994 and 1996. From Tilapia to Barramundi, these ocean-dwelling delicacies will tantalize your taste buds with unique flavors and textures. As humans, we have to make the decision for this animal. WWF and 1986 Panda Symbol are owned by WWF. Money generated by ticket sales goes towards whale shark research and conservation in the wild, and the aquarium itself is full of excellent signage and enthusiastic volunteers who educate people about sharks. Seeing animals in captivity makes me sad sometimes, however I know that the animals are actually better off in an aquarium where their health and diet is closely monitored. It is very much acceptable for whale sharks to be held in captivity, especially in an environment that takes their best upbringing into great consideration.

By sparking the awareness, fascination (funds) for these creatures they are given a greater opportunity for survival in the big picture. The media and animal activists love to dwell in the seeming I told you so stories (such as the death of the two whale sharks) however, seeing how they WERE destined to die before they were even brought to live in the seemingly ample conditions in the first place, it is not as if their lives were extended somewhat anyways.

It is a great learning experience that does not need to go away! [79], The whale shark is popular in the few public aquariums that keep it, but its large size means that a very large tank is required and it has specialized feeding requirements. [36][37] A female individual with a standard length of 15m (49.2ft) (and an estimated total length at 18.8m (61.7ft)) was reported from the Arabian Sea in 2001. They would also be less exposed to danger if they are not released back into the wild. [2] In June 2018 the New Zealand Department of Conservation classified the whale shark as "Migrant" with the qualifier "Secure Overseas" under the New Zealand Threat Classification System. The program that the Georgia Aquarium offers is pretty cool. There's something very uplifting about such an enormous animal being so gentle. Well, we sure will if we keep catching them and they keep dying. She seems to have some, I've got a new article in the latest Wired on the science of stress, as seen through the prism of Robert Sapolsky. Visitors can get up close and personal with these gentle giants thanks to the 11 million gallon tank at the Georgia Aquarium, which is the only zoo in the Western World that houses whale sharks.

Demand for their meat, fins and oil remains a threat to the species, particularly by unregulated fisheries. To me the main point that I was able to gather from the article was the Georgia Aquarium bought the whale sharks to benefit their business first, with the animals concern next. Even if there is no concrete way of actually measuring this. They feed almost exclusively on plankton and small fishes, and pose no threat to humans. [62], The BBC program Planet Earth filmed a whale shark feeding on a school of small fish. [58] The many rows of vestigial teeth play no role in feeding.

This is also called passive feeding, which usually occurs when prey is present at low density. I guess that could be too much trauma for the shark once it has adapted to a more domesticated lifestyle. The history of keeping animals in captivity has often been one of a series of failures sometimes culminating in an eventual ability to maintain them for some period of time as new foods, etc. My point on this is that the aquarium is now funding the hunting for and wild capture of whale sharks as well as other exotic animals and thus threatening whale shark population numbers. "We don't know enough about whale sharks to say we can keep them alive for long periods of time in a captive environment," said Jason A. Holmberg, a scientist with the Earthwatch Institute who is studying whale sharks in the Ningaloo Reef in Australia. It seems that the Georgia Aquarium is promoting whale sharks in a positive way by allowing the public to see these huge, magical fish up close.

Im satisfied with Dr. Carlesons explanation of Ralph and Nortons death. As is the complete butchering of entire wild populations. The whales ate only the sharks' livers and left . But thats probably a different discussion . [2], Seasonal feeding aggregations occur at several coastal sites such as the Persian Gulf and Gulf of Oman, Ningaloo Reef in Western Australia, Darwin Island in the Galpagos, Quintana Roo in Mexico, Mafia Island of Pwani Region in Tanzania, Inhambane province in Mozambique, the Philippines, around Mahe in the Seychelles,[40] the Gujarat[40] and Kerala coasts of India,[44][45] Taiwan, southern China[40] and Qatar. While the whale shark is the largest fish in the world today, an extinct species known as Megalodon was once the largest predator on Earth. Both, i am against fishing for sharks and profiting on either their death or capture. The whale shark is the biggest fish and shark in the world.
