Controversy On Lionfish

The non-indigionous aquatic species are identified as a distinct brown or maroon, and white stripes or bands covering the head and body. Fleshy tentacles above their eyes and below the mouth; fan-like pectoral fins; long, separated dorsal spines; 13 dorsal spines; 10-11 dorsal soft rays; 3 anal spines; and 6-7 anal soft rays. An adult lionfish can grow as large as 18 inches, while juveniles may be as small as 1 inch or less. Lionfish have cycloid

Every Jaws fan knows the shark gets it in the end. What they do not know is that too many sharks have gotten it; and that has caused a rapid decline in the shark population over the past thirty years. Since the 1970's, sharks of the Atlantic and Gulf of Mexico shores have declined eighty-five percent. Sharks are vital animal to our world's ecosystem, and if the decline is not controlled; we could be facing devastating problems in years to come. Information has been obtained from two books: The Shark Almanac by Thomas B. Allen and Sharks, An Introduction for the Amateur Naturalist by Sanford A. Moss. Sources also include a number of online references, among them BBC News, ENS News, The New York Times, and two online scientific

Experts are not quite sure how these fish got to the Atlantic. They hypothesize that people have dumped their unwanted Lion Fish in the Atlantic Ocean for up to 25 years. Since these fish are not native to the Atlantic waters they have very few predators. Lion Fish have a negative effect on native fish populations. The Florida Fish and Wildlife Conservation Commission celebrated a day for the removal of Lion Fish. Over 1,000 Lion Fish were removed this day.

Cetacean bycatch in fishing industries has been a highly debated topic for decades and is still considered an ongoing problem(NOAA 8). However, when it is looked at in comparison, the problem of bycatch has already been solved as much as is possible while still allowing fishing industries to fish at all. Cetaceans are defined as marine mammals. Bycatch is defined as any marine life that is caught and returned to the sea, whether it is dead or alive(Brooke 2). Therefore, many marine animals that are considered bycatch are not harmed in any way. Including these animals, the national bycatch ratio is still low(Brooke 3). Many actions have already been taken since this has become an issue that has reduced bycatch

In the field of Invasion Ecology, understanding the four stages of invasion of a specific invader is imperative to understand the invader. This idea is well documented with the rusty crayfish, Orconectes rusticus. The rusty crayfish is a crustacean native to the Ohio River Basin (Hein et al. 2007). However, the rusty crayfish has invaded not only bordering states such as Wisconsin but also far away areas such as Ontario and Oregon (Hein et al. 2007, Sorenson et al. 2012). The reason that the invasion occurs both in nearby and far away areas is that the rusty crayfish moves to new areas through two different methods (Puth and Allen 2005).The rusty crayfish has invaded multiple places in the US and Canada through human mediated jump dispersal

Florida’s ecosystems are at risk due to the invasive species which inhabit our state. Because of the negative impact of the invasive species of Florida, we should be informed and aware of the effects. There are many non-native, not only animals, but plant species also which are of concern. Three invasive species that are harming Florida are Lionfish, the Burmese Pythons, and the Brazilian Pepper.

They feed during the day and at night on fishes and cephalopods, and they are known to attack smaller dolphins that are involved in the tuna purse-seine fishery in the Pacific Ocean.[4]

The Ministry for Primary Industries maintains that the direct effect of fishing-related mortality on the New Zealand sea lion population is small. In spite of this, research suggests that a plausible hypothesis of the

Although the first three stages of an invasion are important to understanding the invader, the impact stage of invasion is more important because it includes all the effects an invader has on the invaded ecosystem. For the rusty crayfish, Orconectes rusticus, the impacts it has on an invaded area are a result of its natural behavior (McCarthy et al. 2006). Although this behavior is similar to native crayfish, the rusty crayfish is faster and more resilient than any other native crayfish (Kuhlmann 2008). As a result, the rusty crayfish not only outcompete other native crayfish, but also extensively preys on species that are used to the more passive and slower native crayfish (McCarthy et al. 2006). The impacts of the rusty crayfish on new environments include the direct and indirect effects of decreases in local populations, and hybridization with native crayfish species due to its ability to outcompete native crayfish.

Another piece fromscalishic lionfish eat ¾ their weight that means that they eat a ton of fish a day such as snapper REASONING 1 REASONING 2 REASONING 3 This proves that These fish are destroying the ecosystem because they have no natural predators. The only predator that the lionfish have are us humans Based on the evidence one must conclude That lionfish are populationing at a rapide amount. We need to stop the population These facts work together to build a case that show that lionfish just keep eating because they have no predator so they just keep eating.

After reviewing the article, “Camera Catches New Fish Species-as it’s eaten”, one begins to understand the massive effect that invasive species have on native and denizen species. In this specific case, the Pterois volitans (an invasive species commonly known as lionfish) are causing havoc at depths of up to 122 meters (that’s 400 feet). Pterois volitans have been breeding and feeding at these depths for years without any real threats. Human divers are one of the main sources to reduce Pterois volitans population. However, since humans can only dive around 40 meters in depth we are faced with an issue. With the population of Pterois volitans increasing and no substantial means of containing them, more and more fish become eaten. Some of these

The specific species this paper will focus on are the Burmese python (Python bivittate), the Lionfish (Pterois), and the Brazilian pepper tree (schinus terebinthifolius). These specific invasive species have been chosen for their diversity in the animal kingdom and their large impact on the Florida Everglades and Florida’s ecosystem. These species all negatively impacted the host environments. The different types of harm caused by these species include overpopulation from no predator in new location cause for invading rural areas that can either be dangerous, disruptive, or both. The species can consume others species to the point of imbalance in natural species population or out eat species food for survival. This paper will include a detailed description of each species including, previous location, specific new location/environment, population, and specific problem. With this collection of information, it will be discussed that the actions taking place to help fix these devastating problems and will discuss how new solutions can be implemented or discussed to help aid the situation.

Majestic, noble, and brave, this famous iconic wild animal on the planet has captivated the people since the beginning of time. They are most feared by other animals thus, known as the king of the jungle – no other than the lions. Member of the genus Panthera, the lion is one of the big cats in the Felidae family. A lion’s head and body size average about 4.5 to 6.5 feet and tail of about 26 to 40 inches in length. A lion also weighs about 265 up to 420 pounds and a size relative to a 6-foot human. These mammals are also carnivores. Lions have always seen hunting in groups called pride. While lions generally avoid a full-grown elephant, lions still prefer their preys large like the zebras, buffaloes, and giraffes. Poised as the top animal in the ecological pyramid, lions have strong physical qualities, fascinating reputation, and an unfortunate decreasing number of population.

The Pterois volitans, commonly known as Lionfish was primarily found in the tropical and subtropical Indo-Pacific to the islands of the South Pacific. Although, throughout the years was encountered as an invasive threat in the Caribbean Sea. It is believed that such specie was first introduced in the wake of Hurricane Andrew in 1992. However, another suitable theory would be that its introduction relies on ships transporting imported goods. Also, in current days it became popular in personal aquariums, although when the specie reaches its adulthood it is released into the ocean.
