American Tuna Research Paper

In a recent assessment done by the International Scientific Committee for bluefin tuna, released in January 2013, found that bluefin spawning stocks, the key measure of adults that can reproduce, have plummeted by about three-quarters over the past 15 years. It’s estimated that the bluefin tuna has dwindled to just 3.6 percent of its original population once found in the fifties. More than 90 percent of blue fin tuna being fished out from the sea today are juveniles between the ages of 0 and 3. (Walsh) The major problem with juvenile

The United States market for the Anchoveta is primarily canned fish sold as anchovies. The rest comes in the form of fish meal for producing animal feed.

Is it really unethical to catch carp in this manner?....I guess we can only judge

Hatcheries seem like a plausible alternative because, instead of going out and fishing up all the tuna in the ocean, you're just gathering up a bunch of tuna that were in a very controlled enviornment, thus leaving the wild tuna to swim free and multiply while we continue to enjoy the wonderful taste of Bluefin. It also seems quite easy because all they would need to to is mate two fish together to get started.

Examples of by-catches include marine animals such as sea turtles and sharks. Longline fishing has one of the highest by-catch rates of any gear used to fish for tunas and that the average rate is 28%, more than a quarter of the total catch (World Wildlife Fund). There is a possibility for longline fishing to catch more than 80 species of non-target wild marine life per harvest, and many of the creatures are discarded or left for dead (Gulf of Mexico Ocean Conservation

When fishing sometimes you will hang into a log or some under water brush most fishermen will not just cut there line instantly, they will usually try to pull or try different methods for getting the chosen bait out of the snag. Most of the time the line will stretch or break, and

Throughout the day we enjoyed catching countless fish with our petite, freshwater lures, yet the surrounding fishermen never modified their methods of fishing so they also could experience the same enjoyment. They patiently waited while a rod, as thick as a broomstick and as long as a car, sat in front of them, bobbing with the current. Somewhere out in the ocean was their rig, a huge, crippled baitfish swimming around in little circles, struggling, just calling for some hungry beast to engulf it. Those fishermen never caught much, but when they did it was always a monstrosity, twenty pounds or more. Word had it that just a week earlier a man had even caught a one

Thunnus Thynnus, or the Atlantic Bluefin Tuna, is one of the largest species of tuna, weighing in at over 600 kilograms and four meters in length. It is known for its speed and takes the shape of a torpedo. In its environment, the Atlantic Bluefin Tuna acts as one of the top predators. It preys on smaller fish, such as herring, mackerel and eels. The Atlantic Bluefin Tuna is separated into two main populations, Eastern and Western. Although located in different geographical areas they are not isolated and individuals migrate between the two populations allowing gene flow. The Atlantic Bluefin Tuna’s population ranges all through the pelagic zone of the Atlantic. The Western Atlantic population spawns in the Gulf of Mexico, and the Eastern Atlantic population spawns in the Mediterranean Sea. In the fishing industry it is highly coveted for sports fishing, especially in the United States and Canada, and in the sashimi market for high-end sushi. As a result of the high demands for the Tuna it is being heavily overfished causing the population to decline dramatically. The low supply and high demand for the Tuna has made them extremely valuable; a single fish in Tokyo 's Tsukiji fish market sold for 1.76 million dollar (Bluefin, 2013). This high value of the Atlantic Bluefin Tuna has resulted in illegal pirate fishing causing more harm to the population. If the illegal pirate fishing and overfishing of the Atlantic Bluefin Tuna continues, the species will become extinct resulting

Japan’s new industries while mass exporting Japanese made products began to look for products abroad that were suitable for domestic use and consumption (Aoki, 2010). Coinciding with the popularity of sport fishing of the Atlantic bluefin tuna in Europe, Japanese businesses found importing the Atlantic bluefin tuna catches were more profitable then not at all. (Aoki, 2010). This began the market for Atlantic bluefin tuna in Japan and its status as a highly desired fish. The 1970s passed with increasing demand leading to the beginning of overfishing rates have diminished the Atlantic bluefin tuna population today (Aoki, 2010). The expansion of the Japanese sushi/sashimi market into the international domain in the 1980s created a higher demand of sushi grade fish (Fromentin and Powers, 2005). Atlantic bluefin tuna already in sushi menus became the target of the record breaking catch rates. This turned what was once sport fishing of the Atlantic bluefin tuna into a rewarding profession. For instance, one Atlantic bluefin tuna in Japan at the weight of 342 kg was sold for $396,000 in 2011(marinebio.org, 2013). Numerous other record breaking auction prices have made the news as the Atlantic bluefin tuna population continues to decrease. However, damage to the western Atlantic bluefin tuna population may soon be irreversible.

Some of these ways are the texas rig, drop shot rig, wacky rig, and the carolina rig. All of these bring a different look the the fish. First let’s talk about the texas rig, it is the most common of them all, it is also the most basic. The texas rig requires a bullet weight that slips on your line and then you tie your hook on. After that you hook the plastic worm through the head and come back out after about two centimeters, you then hook the worm again in the body, but make sure your hook does not come all the way through because you want it to be weedless and not get snagged up (Neporadny, 102). The drop shot rig most people think is a very difficult way to fish but it is actually very easy. It has a few more steps than other rigging techniques but it is a very good way to catch more fish. It starts out opposite of the texas rig, because you are tying on your hook first and not your weight. While tying on your hook you want to leave anywhere from twelve to thirty inches of line after the hook is tied on. The amount of extra line is based on how high you want your worm to be in the water. The extra line is where you tie on your weight and it makes it so the worm is suspended in the water off of the bottom. The plastic worm is hooked the same way as a texas rig (Neporadny, 110). The wacky rig is a very simple and effective way to catch fish. You can use any type of weight in this technique.

Fishing has been around a long time and has been evolving over the years. In fact, the first known fishermen were from the Stone Age. They used materials that were available to them to catch fish and put food on the table for their families. Succeeding the Stone Age however, fishing has slowly begun to transform into more of a sport than a method of providing food. National Geographic states, “It wasn't until the 15th century that fishing began its evolution into a sport. Previously, fishing was simply a means for survival.” Fishing has changed so immensely that it has become a competitive sport. Fishermen all over the world angle competitively against each other in huge tournaments for a living. These professional fishermen are awarded millions of dollars to angle out of expensive boats that their sponsors pays for.

A comfortable silence lies between my dad and I while we drive to our current fishing spot.  I let my thoughts wander to fantasies of hooking a nice sized Papio or anything actually above a pound. When the car pulls up to the water, I jump out and take out the various equipment.  My dad begins meticulously setting up the rods and reels as I grab one of the longer hand poles, attach a piece of bait, and plunk it down in the water.

The Marine Mammal Protection Act put dolphins under protection standards for the domestic American fishing fleet and for countries whose fishing boats catch yellow fin tuna. It states explicitly, “if a country exporting Tuna to the United States cannot prove to United States authorities that it meets the dolphin protection standards set out in U.S law, the U.S government must embargo all imports of the fish from that

Many breeds of fish are being captured at a faster rate than they can reproduce. Some species such as orange roughy fishing became popular in New Zealand in the 1970’s. Over time, it spread to many countries around the world. In the last 20 years, there has been a decline in catch up to 75%. It is no longer common to see in grocery stores as well as restaurants. The amounts of fish that are captured and distributed around the world are alarming opposed to the rate the fish can multiply.

In the Eastern Tropical Pacific Ocean (ETP), tuna schools are identified by tracking dolphins, the species are commonly known to swim above tunas, and harvested by using large "purse seine" nets which leads to dolphins mortality accidentally trapped with tunas . The US Marine Mammal Protection Act (MMPA) of 1972 forbade the importation of yellowfin tuna harvested with large purse-seine nets (primary nation embargo) in the ETP except when the harvesting country was recognized by the competent US authorities to have an equivalent programme of taking tuna to that of the US
