Turtling is the hunting of turtles. Turtling has been a part of human culture since as far back as the middle of the first millennium BC, where sea turtles such as the hawksbill sea turtle (Eretmochelys imbricata) were eaten as delicacies in countries such as China. [1] While consumption and hunting of turtles is less common than it was in the past, this practice is still a part of communities throughout the globe, whether done legally or illegally.

History

In Melanesian societies, it was common during funeral ceremonies, for locals to partake in a feast of turtle meat and other delicacies. The deceased were sealed into a tomb, and several years later it was tradition to reopen the tomb and to indulge once more on turtle meat. Because turtle meat was relatively rare, hunting the turtle for others during this time was considered to be a display of public generosity. While turtle hunting within this culture is not as common as it was decades ago, locals on Murray Island, Australia, continue to hunt green sea turtles (Chelonia mydas) during the turtle mating season. The turtles are pursued by groups of 3-6 hunters, where a leader, around one decade older than the other members of the group, uses a harpoon to kill the 100–150 kg turtle. [2]

Ecological research shows that turtle numbers decline with proximity to human settlements. This can be explained directly due to the hunting of turtles, or also indirectly with the ecology of fear principle, predation. [3]

Species at risk

While there are several turtle species at risk, the loggerhead sea turtle (Caretta caretta), which made the IUCU endangered animals list in 1996, and the leatherback sea turtle (Dermochelys coriacea) which has been experiencing a decline in numbers, are both still being hunted or killed due to human impact. [4] Another turtle species that can be hunted (not commercially) while considered as special concern at the Canadian and Ontarian level is the snapping turtle (Chelydra serpentin). [5] Hawksbill sea turtles have been hunted for their shells primarily to make jewelry. [6] Tourists will often buy items without being informed of the source of the material. Green sea turtles eggs are poached and eaten in many countries; this is also a tourist attraction and taking sea turtle shots, consuming raw turtle egg with whiskey or beer is popular in places like Costa Rica. [7]

Fishing bycatch

Capturing turtles as a byproduct of fishing has been recognized as a severe threat to turtle populations. [8] It has been acknowledged that fishing nets are the most devastating of fishing equipment to turtles, whether turtles are hunted intentionally or not. [9]

By region

Australia

In Australia it is estimated that 326 turtles from 6 different species, including the flatback sea turtle (Narator depressa) accounting for 59% of captures, and the hawksbill sea turtle accounting for 5%, were captured between 1989 and 1990. [8]

Africa

With a coast line of approximately 30,000 km, it is evident that Africa relies greatly on the fishing industry to feed the people and also as a trade product between other countries. [10] It is estimated that in Africa, an average of 180 turtles are caught per year using fishing hooks alone. Capture rate of turtles using a standard fishing hook is approximately 16 in 100,000. A sixteenth of the captured turtles are leatherback sea turtles, a species of turtle in which population numbers are declining. Conservation ecologists have estimated that should fishing efforts increase and fishing distribution remain the same, these numbers will increase to 770 turtles per year, threatening risked species of turtle. [11]

The radiated tortoise (Geochelone radiata) in Madagascar is in serious decline due to over-exploitation. The tortoise is protected under Malagasy law and is part of CITES, however enforcement is low and hunting persists. [12] Guards that are meant to protect the tortoise and prevent hunting are often paid off by the hunters.

Mexico

In Mexico sea turtles have been used for medicine, food and decoration since the 13th century. While hunting turtles is strictly forbidden in Mexico, approximately 35,000 turtles have been poached per year within the last decade around Baja California Sur. An estimated 65% of captured turtles are thought to be green sea turtles, while 10% consist of the endangered loggerhead sea turtle. The most common way poachers capture turtles is using a net designed specifically for turtles, which costs around $660. The majority of the poachers are local fisherman, who earn approximately US$78 per week. The turtles are sold locally, or reach the international black market where they fetch a profit of US$58 per turtle. [13]

The maximum punishment in Mexico for the poaching of turtles is nine years in jail and a fine of US$11,000. Poachers told researchers that the most efficient way of avoiding being caught is to either physically avoid patrols by driving away from them, or by paying a bribe. [13]

North American regulations on turtle hunting

Both the American and Canadian governments regulate the consumption, hunting and destruction of turtles and their eggs. [14]

In Canada, it is illegal to hunt or kill turtles in most provinces. Ontario allowed snapping turtle hunting as recently as 2016, but that was discontinued in 2017. [15] [16]

In the US, some states have imposed bans on collecting turtles from the wild, including for their meat. [17]

Turtle hunting in New York State regulates two species of turtles, the diamondback terrapin and the snapping turtle. Snapping turtles are allowed to be hunted only between July 15 and September 30. A small game hunting license is required to hunt the turtle, and it is mandated that the turtle shell must be 12 inches long, or longer in a straight line. Turtles must be killed with a bow or firearm, and there is a limit of 30 turtles per year. Because of risk of food-borne contaminants, health advisories have been implemented with specific cooking instructions for public health. [18]

Similarly to regulation of snapping turtles, diamondback terrapin turtles are only allowed to be hunted during specific months of the year. The hunting season for diamondback terrapin turtles is from August 1 to April 30. In order to hunt diamondback terrapins, individuals must possess a hunting license specific to the species of turtle. Shells must be between 4 and 7 inches long, and must be released if the shell size is any different. Diamondback terrapin turtles must be captured by dip nets, seine nets, by hand or with a trap that must be checked on a daily basis. [18]

Regulating poaching

One of the most difficult obstacles to overcome with the hunting and poaching of sea turtles is the cultural aspect. Many countries, such as Costa Rica, have been hunting and eating sea turtles and sea turtle eggs for a very long time and consider it to be part of their culture. When scientists and conservationists try to explain to native poachers the detrimental impact their actions have on sea turtle populations, or when walking nightly patrols on the beach, they are met with hostility and sometimes violence. [19] Continuous education and outreach is important to mitigating the issue, in addition to beach patrols to prevent poachers from taking eggs or nesting female turtles. Implementing laws that protect animals, such as the radiated tortoise in Madagascar, can help population levels if proper enforcement is in place. [12]

Turtles are an order of reptiles known as Testudines, characterized by a shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira and Cryptodira, which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other reptiles, birds, and mammals, they breathe air and do not lay eggs underwater, although many species live in or around water.

The hickatee or in Spanish tortuga blanca, also called the Central American river turtle, is the only living species in the family Dermatemydidae. The species is found in the Atlantic drainages of Central America, specifically Belize, Guatemala, southern Mexico and probably Honduras. It is a relatively large-bodied species, with records of 60 cm (24 in) straight carapace length and weights of 22 kg (49 lb); although most individuals are smaller. This is a herbivorous and almost completely aquatic turtle that does not even surface to bask. Bizarrely for reptiles, the eggs can remain viable even after being underwater for weeks -in the recent past, some scientists mistakenly claimed it nests underwater, likely due to visiting Central America during a frequent flood, when nests are often submerged.

This tortoise is a grazing species that favors semiarid, thorny to grassland habitats. In both very hot and very cold weather, it may dwell in abandoned fox, jackal, or aardvark holes. The leopard tortoise does not dig other than to make nests in which to lay eggs. Given its propensity for grassland habitats, it grazes extensively upon mixed grasses. It also favors succulents and thistles.

An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration.

<span class="mw-page-title-main">Threats to sea turtles</span>

Threats to sea turtles are numerous and have caused many sea turtle species to be endangered. Of the seven extant species of sea turtles, six in the family Cheloniidae and one in the family Dermochelyidae, all are listed on the IUCN Red List of Endangered Species. The list classifies six species of sea turtle as "threatened", two of them as "critically endangered", one as "endangered" and three as "vulnerable". The flatback sea turtle is classified as "data deficient" which means that there is insufficient information available for a proper assessment of conservation status. Although sea turtles usually lay around one hundred eggs at a time, on average only one of the eggs from the nest will survive to adulthood. While many of the things that endanger these hatchlings are natural, such as predators including sharks, raccoons, foxes, and seagulls, many new threats to the sea turtle species are anthropogenic.

<span class="mw-page-title-main">Angonoka tortoise</span> Species of tortoise

The angonoka tortoise is a critically endangered species of tortoise severely threatened by poaching for the illegal pet trade. It is endemic to Madagascar. It is also known as the angonoka, ploughshare tortoise, Madagascar tortoise, or Madagascar angulated tortoise. There may be less than 400 of these tortoises left in the wild. It is found only in the dry forests of the Baly Bay area of northwestern Madagascar, near the town of Soalala .A captive-breeding facility was established in 1986 by the Jersey Wildlife Preservation Trust in collaboration with the Water and Forests Department. In 1996, 75 tortoises were stolen, which later appeared for sale in the Netherlands. The project was ultimately successful, achieving 224 captive-bred juveniles out of 17 adults in 2004. Project Angonoka developed conservation plans that involved local communities making firebreaks, along with the creation of a park to protect the tortoise and the forests. Monitoring of the angonoka tortoise in the global pet trade has also continued to be advocated.

<span class="mw-page-title-main">Species affected by poaching</span>

Many species are affected by poaching, including illegal hunting, fishing and capturing of wild animals, and, in a recent usage, the illegal harvesting of wild plant species. The article provides an overview of species currently endangered or impaired by poaching in the Americas, sub-Saharan Africa, and South-East Asia.

Worldwide, hundreds of thousands of sea turtles a year are accidentally caught in shrimp trawl nets, on longline hooks and in fishing gill-nets. Sea turtles need to reach the surface to breathe, and therefore many drown once caught. Loggerhead and hawksbill turtles are particularly vulnerable. Nearly all species of sea turtle are classified as Endangered. They are killed for their eggs, meat, skin and shells. They also face habitat destruction. Climate change has an impact on turtle nesting sites. As fishing activity expands, this threat is more of a problem.
