Hence, overfishing threatens coastal nations down to the local level, devastating communities whose dominant sources of labor and revenue hinges on healthy, plentiful stocks of fish. Also, marine life imbalance may affect the targeted fishing of top predators such as billfish, sharks and tuna that eventually disturbs marine communities. In fact, it is causing increased abundance of smaller marine animals at the bottom of the food chain. This in turn has impacts on the rest of the marine ecosystem, such as the increased growth of algae and threats to coral reef health.
Other than the negative affect coral bleaching has on jobs and the job industry, and on ecotourism in _ locations, there are many other useful coral _. Corals provide people with food, medicines, resources, and protection. Whether caught or bought, fish and marine animals that live on corals provide humans with a source of food. If corals die, many human ecosystems that rely on fish could hit hunger. Renee Cho of State of the Planet says, “more than half of new cancer drug research is focused on marine organisms,” (# 13) and there are probably thousands more researchers could find by researching healthy corals.
Oxacillin: This antibiotic act to the cell of the bacteria, it block the growth of the cell wall which result in kill the bacteria. Usually it administered by injection. Hypothesis: For mezlocillin I guess it will not work as well as other antibiotics because it has higher chance at gram negative compared to gram positive, which are Micrococcus luteus and Bacillus subtilis. Also penicillin has been used for many year because of it continuously use many bacteria has got resistance to it
Most other alternative methods are very harmful to the environment and the aquatic plants and animals. There are many different types and techniques of fishing that are used all around the world. The most used method is called angling. Angling is the act or art of fishing with a hook and a line. They are usually attached to a fishing rod (Dictionary, Dictionary.com, 2018).
Contamination with pathogenic bacteria from the human/animal reservoir can occur when the landing place is unhygienic or when the fish are washed with contaminated water. Upon the processing of fish, its exposure to water is a critical part as pathogens may be present in the water used which can cause contamination and spoilage (Shoolongela & Schneider, 2012). Contamination of food can occur because of problems in food production, preparation, storage or cooking. The aquatic environment and soft tissue of fishes make it extremely susceptible to microbial contamination. Contamination commonly occurs in the environment in which the seafood (fish) is usually caught, during harvesting, and preparation (Wekell, Manger, Kolburn, Adams & Hill, 1994).
Tests conducted by Geological Survey have shown that tuna is high in mercury which may kill a person. Do you love seafood? If you are great sea food lover than we suggest you to try wild caught food such as salmon or take some medicine such as chlorella tablets in order to help your organism absorb the mercury from the fish. Also herring, sardines and anchovies are great option due to their short life.
Goldfish, Carassius auratus: Superb in Large Unheated Aquariums Goldfish grow. Common goldfish can grow up to approximately 12 inches in length which is larger than some of the containers the juveniles are kept in. They also produce a good deal of waste as they grow. Fancy varieties usually stay smaller than common goldfish, but their fancy fins are inclined to develop finrot in dirty water.
This essay will be investigating the extent to which people must reduce overfishing in order to preserve animal populations. Overfishing can be defined as ‘the catching of too many fish resulting in the deterioration of marine biodiversity and food systems, as fish populations decline.’ This essay will overlay the perspectives of Hong Kong, the perspective of Japan, and finally the significance of overfishing on me and my family.
One of the leading causes for reefs to be endangered is due to the invasive lionfish. The lionfish’s impulsive eating habits are threatening our sea life of the reefs and decreasing our fisheries economically. According to Lionfish Hunters, the green side includes the cleaners that maintain the health of the reef and the health of other fish such as “grazers.” The grazers are the parrotfish, goatfish, wrasses, surgeonfish, and tangs. (The Lionfish Hunters, web.)
The diet of a viperfish consist of shrimp, hermit crabs, anchovies, mackerel, and other small fish they can feast on. They can go days without food because of their very low basal metabolism rate. They also have a large stomach that allows them to store food when it is needed. When they see a prey they want they go straight at it and headbutt it and hopefully it would get disoriented and the first vertebra right behind its head acts as a shock absorber and take all the shock from the impact so they don't get a concussion.
they can reach sizes of upto 10 to 12 inches. they will become ill above 75 degrees (lynn, jennifer).ph should be between 6 to 8 which is the acidity in the water. the goldfish eat worms shrimp vegetables and other things.the oranda goldfish are long lived fish but are delicate fish (jennifer
All About the Grouper The grouper is basically a kind of fish under the family of sea creatures that include the sea bass. They have a sort of scary looking build, which makes them popular for use by artists in some TV cartoon series. So, what does the grouper exactly look like? Picture this: a fat body, a huge mouth, and an overall aura that will basically tell everybody who will see them that they are not worth this grouper 's time and attention.
We should also try our best to prevent it because there are more dangerous diseases that can spread by ticks. Right now, scientists have discovered fifteen different diseases that are caused by ticks. One of them is called Powassan virus. Symptoms of this disease include “fever, headache, vomiting, weakness, confusion, seizures, and memory loss” (“Powassan Virus”). Powassan virus is far more dangerous than Lyme disease not only because of the severe symptoms; there are no specific treatments or any cures for it.
Sea lice are parasites that occur naturally on many different fish but due to the condition of being farm raised they spread faster and even fish in the open ocean passing by the the farms are being infected. This in turn effects other fish in the ocean. The fish are often given pesticides to combat sea
Even though jellyfishes do have tentacles that release nematocysts which injects the animal with toxins, it does not stop animals from eating it because some animals are immune to their sting. Don’t worry the purple striped jellyfish is not endangered. These jellyfish survive anywheres from two to six months but they come from humble beginnings. Death is often caused by rough waters. This type of jellyfish reproduce sexually.
