The biggest dependency of which one you like more is where you live. If you live on the outskirts of a state that is next to the ocean, you have the ability to go fishing in the sea or in freshwater. For people who are landlocked, they are forced to only fish for freshwater fish. Some people also get sea sick when deep sea fishing, so that makes them not like it as much as other people (K, Jay n.p.). The size of the fish
Nevertheless, the orator impugns this assertion by stating that animals who apply this style of living tend to move slow and they usually stay in a certain location. However, fossils of these species indicate that they were speard in enormous expanses of the ocean and they were able to move rapidly which contradicts with the fact that species in the seafloor occupy a certain geography. Therefore, this theory is unable to explain their style of
Orcas with different backgrounds and dialects are placed together without much thought about how this could affect them. A killer whale named Tilikum was placed in Sealand and he was expected to perform tricks that he had never done, and if he performed them incorrectly all of the whales were withheld food. “This annoyed the others, so they would rake him with their teeth, causing him to bleed” (Lewis). In the wild, when a dominant orca begins showing aggression the other orca has thousands of miles to swim away and flee the scene. However, these animals are in pools where they do not have that option.
Fishery Management: RBM and Fishery Subsidy Over fishing around the globe has lead to a dire need in effective fishery management as it has led to fisheries depleting worldwide. Seafood is one of the more popular delicacies around the world and is also the source of income for millions of fishers globally. Lack of and poor fishery management has led to an exhaust of the fish stock in the ocean, which in turn has had a negative impact on biodiversity. Poor management has also been a factor economically as it leads to a loss of about $50 billion annually for fisheries around the world. If proper steps are taken the problem can be managed, Fishery Solutions Center believes that if management is improved then abundance of fish can increase by
Sharks, dolphins, turtles, seals and seabirds all get tangled in these nets, as by-catch, with no way to get out. Some of the animals that are caught die, either while they’re being dragged along the bottom of the ocean or when the fishermen bring them on deck and don’t put them back fast enough. FAO experts assessment concluded that there are roughly 27 million tonnes of global by-catch for every 77 million tonne catch. This statistic means almost 1/3 of every catch is by-catch. Fish populations are on the decline, no thanks to carless fishermen and their pollution.
Adaptation to live in the habitat lack of oxygen A. Crayfish: Crayfish lives in fresh water stream, which is an aquatic environment. The oxygen level in fresh water upper stream is higher than the lower stream, but the oxygen concentration is still low. The gills of crayfish are much bigger than the size at first glance. They occupied under the cephalothorax carapace in branched-shape and provided a large surface area to volume ratio to carry out gas exchange. Fresh water will be pulled into the cavity by the movement of the “gill bailers”.
People have been fishing since the beginning of time, and right know that is being threatend because of over fishing. I am a big fan of seafood and so are millions upon millions of other people. The problem is that people fail to realize the problems caused by over fishing because they only have to drive a short distance to a store, buy their fish, and go about their daily lives. They are unaware of the damage that fishermen are causing to the oceans around the world. Especially the Atlantic ocean The Atlantic ocean is struggling right now in terms of it's wild life.
I believe keeping orcas in captivities is not humane .To keep orcas in a zoo for display is acceptable, but it is morally unacceptable to use them for entertainment at SeaWorld. I saw the film Blackfish and now, I resent SeaWorld. They care more about profit than animal welfare. Keeping these sentient animals in captivity for an extended period of time causes them severe psychological damage, as evidenced by several killer whale attacks on trainers. SeaWorld Entertainment has had a rough year in the wake of Blackfish, the explosive 2013 documentary about its killer whales, most notably Tilikum, a 12,500-pound male who has fatally attacked two trainers.
However, I caught a 42 inch shark in Florida (saltwater) which took me 20 minutes to reel in, and that is considered a small fish. They both have unique characteristics that make them completely different things. I’m going to prove that all fishing is not the same, saltwater and freshwater fishing are different sports based on dangerousness, cost, species, bait, and boat type. Most people assume fishing is a safe and easy hobby, however, fishing can actually be a dangerous activity. Saltwater fish have the potential to pull you into the water, bite you, or even sting you.
Ocean acidification is killing off the oyster population, which is also affecting the jobs in Washington. Initially, ocean acidification is when acidic gases are emitted into the air and absorbed into the ocean. According to the video Ocean Acidification by NOAA, ¼ of all the carbon dioxide release into the air is absorbed into the oceans. Some major contributors to carbon emissions are automobile gas and factory emissions. This is a problem in the Pacific Northwest because acid sinks to the bottom, but Pacific winds bring acidic water up from the bottom near the shore by the shellfish.
In the wild, orcas spend up to 95 percent of their time submerged and would find shade in the depths of the ocean, but at SeaWorld, their tanks are far too shallow. Their deepest tank is 40 feet deep—not nearly deep enough to give them a reprieve from the harsh elements. Because of this, orcas have perpetual sunburns, which are shielded from the public eye with the help of black zinc oxide, which matches their skin. Although zinc oxide is also used as a sunblock, orcas almost always have sunburn before it is applied. When I read this I was appalled.
