The Yellowfin Tuna, Thunnus Albacares

Its body is slim and egg-shaped shaped in cross section. The corner of the mouth spread out past the eye, this is why it’s called the largemouth bass. (Bailey, et al., 2004; Boschung, et al., 2004) Young largemouth basses eats zooplankton and insects that is in the marine.

The estimated relative batch fecundity is more than 90 eggs/g of female’s body weight. Bluefin tuna Aquaculture: The farming of Atlantic bluefin tuna began as early as the 1970s by Canadian fishermen who captured young fish and raised them in pens. The development of tuna farming continued in order to meet the growing demand for tuna in Japanese market.

The biggest sharks eat baby fish, shrimp, plankton, and many tiny animals. Some sharks eat bony fish, squid, and can also be cannibalistic. They usually feed on smaller sharks. Great White sharks eat fish, and as they grow start to eat seals and walrus. Tiger sharks will eat anything and everything, such as dead animals, coal, tires, and clothes.

In some parts of the world, abalone has been considered a luxury food and served in special occasions such as weddings. Depending on cultures and preferences, abalone may be consumed live and raw, used in sushi, or served steamed, salted, boiled, or chopped. Capture fishery: The high value abalone fishery used to be the main production system supporting the livelihood of many fishermen especially in Asia. Because of variety of reasons, abalone world fishery witnessed a considerable decline from 16,800 tons in 1980 to around 7,200 tons in 2015.

Along with this, most large seafood industries manage their own farming organization with aim to produce fresh, frozen, smoked or even canned before selling to local or international markets. (Boziaris, 2014) In the U.S., the packed for fish or shellfish products that have been canned differ each year between 500 million to a billion pound with tuna, salmon and clam as the major products. (Sea Grant,

Anglerfish posess a modified dorsal fin, the illiceum, at the tip of which is a bulb, the esca, which contains symbiotic luminescent bacteria. This esca is used both as a light to guide the fish, but also to lure prey to the anglerfish’s mouth. (Munk, 1998). The Cookiecutter shark’s bioluminescent cells imitate the faint light of the surface above, camouflaging it when viewed from below and so allowing it to approach its prey without being seen. This tecnique is called counterillumination and is used by numerous organisms in the deep sea; both

v. Sukumaran et al. , (2014) use a cast net measuring 2.5 m long, with a mesh size varying from 7 mm at the base and 15 mm at the apex was employed in the collection of fish throughout the period of study and the net was hauled 10 times during every collection at the sampling site. vi. Mwaluma (2010) studied community structure and spatio-temporal variability of ichtyoplankton in Kenyan Coastal waters method use the light trap fabrication and deployment. The traps were deployed per tide during high tide at depth 10-18m for 12 hours.

Many countries like the United States have had over fishing crisis that have been resolved 1. Many countries such as Australia, Chile, Belize, Namibia, Denmark, and the United States, have faced similar problems but the fishing rights they have enforced have helped transform struggling fisheries. Which would be key for the lower status countries. 2.

They are carnivorous, do not eat any plants. Their long and narrow saw-bills are well adopted to catch fishes. Often they appear in pairs or family groups. The male duck at left has dark green head, red bill and black white plumages and the female with a catch at right has brown head and grey plumages. A merganser mommy leads her babies swimming and feeding in the waters.

Once you feel that you have a fish on the line, you can set the hook and bring in the fish. This method is a good way to make sure that overfishing does not happen. Overfishing is when a body of water gets fished so much that the fish population is almost extinct in that body of water. Overfishing happens a lot more often when people use different fishing methods like cast nets. Cast nets and trolling lines are where a fisherman places nets deep in the water, and they extend from ten to one hundred feet.

This graph shows a more stable recording in the movement of this type of orca; the furthest that the whale in graph B dives is about 75 meters. Resident killer whales are also known to only prefer fish, opposed to the transient killer whale, which targets marine mammals. The graph also supports the fact that resident killer whales are exactly what their name says, they are familiar with the territory they inhabit, which allows them to frequent and move about more, where as with the transient orca, they could only go so far because they navigate and dive according to where their food is. Both graphs are very distinct in terms of figuring out which type of killer whale it depicts; the resident killer whale has a very consistent dive and depth pattern, and is very easy to detect because of the obvious background of its kind—what it preys on as well as where it usually migrates to, where as the transient killer whale has a more spaced out graph, due to the fact that unlike the resident killer whale, it stays more to the coastal areas and would only dive deep to seek out other marine mammals to prey

I have swum with Caribbean reef sharks in the Bahamas and have seen how beautiful and strong they truly are first hand. Sharks are a vital part to every ecosystem they are in and currently being killed at a rate that they cannot reproduce at. Alpha predators are a necessary component of eco-systems because they keep the populations of every trophic level below them in check. You can compare an eco-system to a skyscraper; you need every single part so the entire building does not fall apart. Sharks have the task of killing the wounded, old, and sick fish in schools to keep the stocks of fish healthy and plentiful.

In addition to birds, plenty of fish can be found in the basin and fishermen frequent the basin in search of Tilapia (3). Tilapia can be found by the hundreds in the basin along with corvina and an occasional striped bass, mullet, croaker, or sargo (3). The endangered pupfish, though rare, also rely on the basin for survival (10). Pupfish are also the only native species in the Salton Sea, thriving in shallow bodies of water with a high salt and heat

In order to do this, they had to stab the fish while in a canoe and put the fish in the storage section. This proved to be more useful when catching larger fish such as swordfish, or blue tuna. The most effective method of catching salmon was by using large nets shaped like a V to catch hundreds of fish at a time. This was very useful because one thousand fish could easily feed a family for a whole year. Another way fish were caught was by using traps, most commonly a weir was used.

This beautiful looking fish packs a punch: The fish has venomous spines that deliver an extreme pain that can last for days. In extreme cases, the venom can even cause paralysis. The LIonfish is an apex predator on the reefs using its fins to coral small fish and anything it can fit into it’s mouth into a corner before it strikes quickly swallowing it whole. The lionfish feeds on an array of over 50 species including ecologically and economically important species. ("Lionfish Biology Fact
