Dr Carl Meyer from Hawaii Institute of Marine Biology stated that mass levels of shark culling “runs the risk of ecosystem-level cascade effects where a general lack of sharks results in boom or bust in populations of species further down the food chain”. Furthermore when nets are used to trap sharks, often animals such as dolphins, turtles, whales and dugongs become trapped in them. Turtles are one of the most endangered species as a whole and are just innocent bystanders in this war between humans and sharks. We need to be careful of not affecting other animals in this quest to reduce shark numbers in the name of nothing. Sharks can already be caught legally by commercial and recreational fishers so any cull would be largely
The juvenile Rainbow Parrotfish generally spends its time in "mangrove sanctuaries", areas where the roots of a mangrove tree grow into the ocean and serve as a safe haven for small fish. Unfortunately, due to human interference and other factors, these mangrove populations are waning as well. This is opening these sanctuaries to predators and not allowing the juvenile fish that called them home to survive. The solution essentially narrows itself down to one goal, save the mangroves and, as a result, save the Rainbow Parrotfish. The question that I am asking is: "How much, in detail, does saving the mangroves help the Rainbow Parrotfish?
Many groups are working to make people aware of orcas in captivity and avoid future reoccurring problems like this. Wanda, the first orca captured in 1961, was found off of the coast of california. (orcaaware.org) This large predatory marine mammal soon became
“Apparently the mass of the plastic particles is six times more than the mass of the natural plankton in the area.” This large expanse of ocean has become unhealthy for the animals that feed around the Gyre. “The plastic is found at depths of up to 30 meters. It is literally creating a landmass.” Because not all the plastic’s as it breaks down, and releases large amounts of toxic substances into the water of the Pacific Ocean. Not to mention that the Sea birds and other marine animals mistake these sand like plastics as food, and aren’t able to digest the plastics resulting in a large number of deaths of these animals. We all can contribute in helping the slow the growth of “trash Island” so some call it.
With over 1m wild alligators in Florida versus a human population of 17m humans, there’s lots of opportunity for conflict. The beasts can grow to 12ft and their lethargic appearance has misled many a startled holidaymaker, within a flash they can snap their jaws and even run up to 30m.p.h. There are actually Gator Hunters operating in Florida to deal with the problematic reptiles. Obviously the animals know no boundaries but they do not seek human attacks and they usually try to avoid us, however sometimes things go wrong. Pestering, tormenting and throwing food to gators is usually the root cause.
Alligators and they get trapped within the hydrilla. Limpkins, because their primary food source, apple snails, are dying out in the Wakulla Springs ecosystem. Apple Snails and they are being battled because the hydrilla halts the snails as they ascend to the surface, so they drown. Some of the methods that have been used and that have failed are using dip nets, booms, hand pulling and mechanical harvesters The method that is being used now is putting herbicide within the spring. “Hydrilla was imported
Red is the endangered areas In image 2, the most endangered reefs are in areas that are considered “Third World”, where populations have limited access to education. The people here are concerned mostly with putting food on the table now, later can wait for another day. There is a problem with reef systems today that directly comes from people who probably did not know that they were causing it. Runoff from sewers, especially untreated sewage kills corals by: * Suffocating corals and zooxantheallae by covering them with sludge and cutting off
Shark Cull POV Shark Cull POV Good afternoon everybody I’m here to talk about how shark culling is effecting the environment and how it is affecting other species in the marine life. Shark culling not only endangers other marine species, but it also targets endangered shark species and the number of sharks are continuously reducing. Netting for example is an unreliable source of culling sharks as it not only affects sharks, but also affects other species which is not healthy for the marine economy. By culling sharks they are preventing sharks from producing in numbers and increase endangered species. Not only does culling affect the sharks it also strikes the eco system of coral and reefs.
Africa and Florida’s environment both have issues and damages. The damages of the environment affect the animals that live in the area. Florida is known for its pollution in certain areas and this is what hurts the animals, from ranches and farms polluting the watered area where animals live they die off because of what is thrown in the water. In 1990, Florida Legislature banned drilling. This drilling happened on the coast-line with this happening most drilling comes with oil and with oil in the way of an animal they’ll get covered in it and soon die.
It feeds on ectoparasites or dead tissue that it picks from the body and oral cavities/gills of these fish (e.g. ; Tangs or Groupers) in the wild or in the aquarium. This also helps to protect the fish from contracting diseases and infections. Many fish value its services so highly that they will allow it to clean the inside of their mouths, and not harm it. Some fish, though, such as Hawkfish, Lionfish, and some predatory shrimp and crabs may eat the Scarlet Skunk Cleaner Shrimp.
