Pelagic fish Essays

1. 90-100 million tons are killed and wiped off the planet each year. Consisting of some of the most beautiful creatures on the planet. Fish are a primary food source to 3.5 billion people worldwide and the depletion of the species is leaving millions of people hungry. Over fishing is a huge problem that needs to be stopped. 2. I will explain what overfishing is doing to families, what we can do to help the situation, and how to repopulate the fisheries. 1. Millions of people rely on fishing for

inhabitants, but we also don’t know enough. There is more in the ocean than the things we’ve seen and studied. There’s things deep down in the ocean so deep that light from the sun doesn’t even reach it. In this deep abyss, there lives fish we have come to call the Chimaera. These fish are found in the deep water where they hunt with their tooth plates which they use to grid into hard bodied prey. Today I will be giving you some information on Chimaeras to increase your knowledge on them and to understand

Atlantic Bluefin tuna (Thunnus thynnus) Introduction: The Atlantic bluefin tuna (Thunnus thynnus) is a pelagic and schooling fish that is also known as the northern bluefin tuna, giant bluefin tuna. The species is the largest member of the Scombridae family and one of the largest bony fishes. Bluefin tunas are known to swim long distances and usually at high speed of up to about 1.5 knots and can also dive as deep as about 900 meters. The average lifespan of bluefin tunas is 15-30 years with up to

speculation about possible causes including climate change, eutrophication, over fishing and invasions (Jennifer E, 2007). The moon jellyfish has become a bit of a nuisance to many different fishing companies, they diminish the size of commercially important fish larvae by either direct predation or due to the result of food competition (Dawson and Jacobs 2001). Reports of human problems with jellyfish have increased and have captured public attention. Jellyfish and jelly-like sea creatures come in an immensely

Research Question: What is the relationship between shark feeding behavior and shark humans attacks, and what are the effect of overexploitation in shark populations? Hypotheses: If sharks have low visibility, they can confound for a fish a man’s foot or calf. If fishing behavior increase, it will be a decline in shark population. There is a significant difference between cruising swimming and filter feeding speeds of basking sharks. Experimental design: • Cruising swimming speeds and filter-feeding

extraordinarily shrewd marine warm blooded creatures and are a bit of the gathering of toothed whales that fuses orcas and pilot whales. They are found far and wide, generally in shallow seas of the territory resigns, and are carnivores, by and large eating fish and squid. The bottlenose dolphin is a champion among the most clearly comprehended sorts of marine very much developed animals. They have an intense body and a short, thick bill. Their tint ranges from light dull to dim with lighter tinge on the waist

to aggregate in schools especially with fish of the same size as well as with various species of dolphins or porpoises. Yellowfin tuna, travel long distances. They have a life expectancy of about 8 years. Distribution and habitats: The yellowfin tuna (Thunnus albacares) is found in pelagic waters of tropical and subtropical oceans worldwide except for the Mediterranean Sea. They are mostly found in the top 100 m of the water column while

Family: Scombridae - Wahoo Description: The wahoo has an elongated scaled body which that looks slightly compressed. It is a bluish green towards the dorsal of the body and silvery towards the bottom. There are

time comes. The idea behind sustainable fishing is that the future generation can fish all they want, without having to compromise the ability of the future generations to fish and enjoy the water’s bounty. Unfortunately, this is now a problem in different parts of the world including Canada. So

The term juvenile is used to describe turtles in the pelagic rafting life stage. In juvenile loggerhead turtles, the center of the dorsal scutes is elevated to form a sharp spine. Juveniles are approximately 40 centimeters in length (Dodd 1988). The oceanic juvenile stage begins when turtles enter the oceanic zone. As juveniles, loggerhead turtles reside in costal areas and migrate seasonally between summer and winter habitats (Lohmann and Lohmann 2003). In this stage, turtles spend 75% of their

kingfish, black salmon, lemonfish, and sergeant fish as well as cobie and bonito (in Spanish) and mafou (in French). Cobias are a popular recreational and commercial species. They reach lengths of 50-120 cm, with a maximum of 200 cm. While cobias are more common at weights of up to 20s kg, there could be few heavier specimens which could reach up to 60 kg. Cobias grow quickly and have a moderately long life span. Cobias are intensely curious fish and show no fear of boats. Both cobia sexes have

Hawaii is a real bliss as it includes all the finest ingredients – stellar beaches, ideal weather, crystal clear turquoise waters and the pelagic world you can’t forget. The Best Hawaiian Island For Snorkeling The best snorkeling in Hawaii is at Maui & Big Island. These 2 islands possess much more snorkeling sites, the coral reefs here are healthier and the pelagic life is richer if to compare with Kauai or Oahu. For those who adore floating over vast coral fields the prime place to snorkel in Hawaii

Whereas many mainland U.S. fisheries are "in­dustrial-strength" with poor reputations for quality, low fresh fish prices, and poor incomes for fishermen, in Hawaii the combination of auctions and direct purchases from outside sources has meant a consistently high-quality prod­uct. However, fresh fish prices have risen considerably since 1970, even adjusted for the general rate of con­sumer price inflation. This has been prompted by the explosion of restaurant

exploited the cod and used different fishing types to catch them more. For example, they were used for fish and chips and it was used all over Europe such as Iceland. While reading, I thought it was interesting that all the things we learned about fishing and endangered species came up in the book. For example, we learned about longline fishing which allowed for the fish to be caught easier, especially in fish farming. In the book, the longline fishing allowed for the cod to

Industrial fishing is the act of catching fish for a commercial profit. The fishing industry can be divided into sub groups of the different methods of fishing such as longlining, bottom trawling, dredging, and gillnetting. The list goes on as for the methods of fishing, but these are the main tactics. Longlining is a serious operation that is one of the top methods of industrial fishing. Known as “The Curtain of Death,” longlining consists of a main line that can run all the way up to fifty miles

help maintain the health of ocean ecosystems and help regulate and maintain the balance of the marine environment (Griffin et al., 2008). These sharks have slow growth rates and reach sexual maturity at a relatively late age compared to other marine fish, which leaves their population vulnerable to any outside sources (Musick and Musick, 2011). Sharks have been apex predators in the ocean for millions of years, however, the populations of sharks have been at risk for years as a result of many different

approximately 100 eggs several times during a nesting season, typically at 8-12 day intervals. Life Cycle Juvenile leatherbacks may remain in tropical waters warmer than 26°C, near the coast, until they exceed 100cm in curved carapace length. Adults are pelagic and live in the open ocean, sometimes

caudal fin of the species is behind several of the common names. This fish has a distinctive golden brown stripe running laterally from the snout to the tail. While it is common to find fish of about 12 years, there are specimens of about 30 years of age. Yellowtail is a highly prized game fish. Description: The species are long with streamlined bodies of greenly blue color on the dorsal surface shading to silvery white beneath. Fish fins are yellowish. The Yellowtail Kingfish can grow up to 2.5 m as

Swift, strong, stealthy, and fascinating, sharks are marvelous fish. They are well known for their incredible sharp teeth, and vicious behavior. Sharks are extremely unique and an essential part of the ocean and sea ecosystem. There are over five hundred different types of sharks living in the world. Sharks can be divided into two main groups, large and small. The large sharks hunt for food so they are fast and agile. The small sharks usually hide in the ocean floor to catch prey and hide from

In the documentary Blackfish, two women recount the story of a Sealand trainer, Keltie Byrne, falling into a pool of orcas and ultimately paying the cost of her own life. These women and an entire crowd of people watched in horror as Tilikum, one of the orcas, pulled her to the bottom of the pool and all three of the orcas took turns tossing her around until she drowned. Since then, orcas have been viewed as dangerous and lethal. However, this is just not the case. These majestic animals are gentle
