Females swim gently near the surface with their dorsal fin almost out of the water. One or more males will accompany her and spawn near the surface. The females release up to 4 million eggs at once (Susie 2009).
Feeding Habits Sailfish feed on Cephalopods and bony fishes mostly (Júnior, et al., 2004) Squid, octopus, mackerels, tunas, jacks, halfbeaks, and needlefish are the most commonly eaten prey. This indicates feeding occurs near the surface, in midwater, and along reef edges (Júnior, et al., 2004).
Endangered Species Status The National Marine Fisheries Service (NMFS) manages the sailfish under the authority of the Magnuson-Stevens Fishery Conservation and Management Act to insure the long-term sustainability of fishery stocks. Commercial vessels U.S. flagged are prohibited from selling, retaining, or purchasing sailfish. Recreational fishers must obtain a permit from NOAA fisheries for fishing in federal waters and state regulations may also apply (Susie 2009). Sailfish populations have been depleted, and don’t look like they are getting any better. However, populations appear to have remained relatively stable since the 1980s based on the observations of the International Commission for the Conservation of Atlantic Tunas (ICCAT) (ARKive
GEOG 304 Research Paper: Shark Finning
953 Words | 4 PagesAndy Dehart, Discovery Channel Shark Advisor, spoke about the North Carolina shark over fishing problem. The shark populations on the East Coast were extremely over-fished which lead to the over population of sting rays, a main food-stock for sharks. The stingrays in turn decimated the shellfish populations on the East Coast, leading to calm and shellfish shortages. This shows that sharks are necessary for every eco-system and their destruction affects us in more ways then we can imagine. Sharks are very at-risk for over-fishing because they take a long time to reach the stage where they can reproduce and in general only have a few pups when they give birth.
Shark Population Lab Report
492 Words | 2 PagesMelissa Ramessar TA: John August 20th 2015 Lab section M 13 The effect on decreasing numbers in the shark population Summary There is a rapid increase of rays, skates and numerous small pieces as a result of the decrease of sharks along the eastern seaboard. As a result of intense fishing of sharks in the northwest Atlantic over the past few decades, the shellfish populations such as scallops and Chesapeake bay oysters are decreasing. One of the contributions to the 73 million sharks killed each year is due to the supply of fins need to make the Chinese delicacy shark fin soup.

Pacific Viperfish Conclusion

They are a bioluminescent creature which mean that they have lights on their body that they can activate.

When it's daylight they hunt at depths of 1500 meters or 5000 feet and when it starts to turn night time they go to shallow waters of about 600 meters or 2000 feet where it is more active and alive with creatures that they can feed on.

Whale Sharks Research Paper
1099 Words | 5 PagesWhale Sharks the largest fish in the world and are found throughout the warmer areas of the oceans. Whale sharks can reach to 18 – 40 feet long and weighing from 12 - 20.6 tons (Bradford A. 2016). As filter feeders, whale sharks eat mostly plankton and other small organism such as zooplankton, copepods, shrimp, phytoplankton, mollusks, and sardines. Whale sharks capture their food by swimming towards it with their mouth open which can get up to 4.9 feet wide and engulfing their prey that enters their mouth (Rafferty J. Young G. 2017). Whale sharks play important part of by clarifying water as filter feeders which is important to the marine ecosystem.
Persuasive Essay On Overfishing
716 Words | 3 PagesFirst, I would like you to understand the scale of this problem. A report from the United Nations (UN) estimates that nearly 52% of the world’s fish population is endanger of being exploited, overfished and eventually even depleted [1].

First, it has a tremendous negative impact on the marine ecosystem.

Marine Conservation Society: Skipjack Tuna
314 Words | 2 PagesThe marine conservation society (2015) states that: Tuna belong to the family called Scombridae. Skipjack tuna (scientific name: Katsuwonus pelamis) are medium sized of the tuna family, are oceanic fish and seasonally migrate from time to time, some making trans-oceanic journeys. Skipjack tuna are found throughout the world's tropical and temperate waters. During the day they school on the surface (often with birds, drifting objects, sharks, whales etc.) however at nights are able to descend to depths of 260m. Skipjack tuna are a very fast growing species, maturing at 2 to 3 years old (40cm in length) and live for up to 12 years. They can grow up to more than 100cm and 34kg in weight but are rarely found larger than 80cm and 10kg.

In 2004, lionfish became established in Bermuda, the Bahamas in 2005, Turks and Caicos in 2008, and the Cayman Islands in 2009. Lionfish were established in all islands of the Greater Antilles by 2007-2009, and some sightings have been reported throughout the Lesser Antilles. The Caribbean coast, all the way from Mexico through to Venezuela, has also seen the establishment of lionfish. Further expansion is probable, as lionfish tend to thrive in the warm waters of the western Atlantic (Schofield
Dolphinfish
640 Words | 3 PagesDolphinfish are in the class Actinopterygii while Dolphin and Porpoises are in the class Mammalia. Dolphinfish are named that way because they make similar sounds or maybe because they are around the same size. Either way, no one really knows for sure. Male and female Dolphinfish are differentiated dramatically by their sexual dimorphism. Examples of sexual dimorphism displayed in Dolphinfish are shown in the following ways; Males have vibrant colorings and much larger than the females.
Summary: The Biotope Aquarium
2541 Words | 11 PagesWithin the first group, Haplochrominae, there are two subgroups. Both subgroups require different environments which is something that you should consider when setting up the tank. The first one, known as Haps, consists of open water and sand dwelling species. The second subgroup is known as mbuna, which means “rockdwellers”. The Mbuna fish are smaller, and both sexes are often brightly colored, though in some species the females may be brownish overall.
