Introduction
Canned tuna quickly grew into one of the most popular seafood products in the United States due to low cost, and its source of protein; making it number two in the top ten consumed sea food products (Campling et al. 2007). Harvesting of the canned Tuna species has raised significant ecological issues and concerns related with economic and environmental sustainability (WWF n.p).
Types of Canned Tuna Species
There are five main commercial tuna species: Albacore, Yellowfin, Bluefin, Big Eye, and Skipjack. The most commonly canned species though include the Albacore Tuna, the Yellowfin tuna species, and the Skipjack tuna species (Canned Tuna, 2014). The following sections provide information regarding the biological species, habitat, trade name, fishing methods and their related advantages, disadvantages and the sustainability of the various canned tuna species.
Albacore Tuna
The scientific name for the Albacore tuna is the Thunnus Alalunga. It is typically a large fish, ranging at approximately 4 to 5 feet in length and weighs roughly 80-90 pounds. It is metallic, identified by a dark blue color running along its topside and a silvery white strip marking the sides of its belly. The Albacore are found in the tropical and warm temperate oceans. The specific locations of the species include the Atlantic, the Pacific and the Indian Ocean. According to the sustainable canned tuna website, the Albacore Tuna is the most abundant and popular species of the canned fish because of its ability to survive in large populations in the temperate and tropical oceans. The trade name of the canned Albacore is the white meat tuna (Hilderbrand, 1-3).
Skipjack Tuna
Katsuwonus is the scientific name for the Skipjack tuna. It is a streaml...

With a coastline of over 202 000 km and over a fourth of the world’s freshwater resources, it is no wonder why Canada’s fishing industry is a huge part of its economy.1 Canada exports more than 75% of its fish to over 130 countries worldwide. Many of the 7 million people who reside on the coast depend on the ocean’s resources. In total, Canada’s entire fishing industry is worth around 5$ billion dollars a year, being one of the world’s most valuable. However, the coasts have not been treated by respect; overfishing, over consumption, and wasteful practices has deteriorated, not only the industry, but the ecosystems and fish populations. This is a huge global issue; the worldwide collapse of fisheries has been project for 2048. Slowly, as the trends continue, we will inevitably see many fish species start to disappear. In fact, the ill-treatment of species on the Canadian border has already devastated a large specie, the cod.
Earth's oceans make up over 75% of the Earth as a whole. With that being said, it is vital to understand the significance on the contents of the oceans. Since fish and marine products make up a large portion of our diet, fishing practices need to be properly managed. In this essay, overfishing will be defined, its consequences will be revealed, and plans for proper fish distribution will be executed.
Much like the banana industry of the past, there was once an incredible variety to the fish one could find and purchase at market, but recently only a few are easy to find at the local grocery store, due to the demand for a consistent and recognizable product. Cod is an instantly recognizable name in terms of fish breeds. It is a fairly bland fish, however its history is anything but; wars have been fought over Cod and it has been a famous contraband commodity. Consumer demand plagues this fish as well as directly influenced its decline. Unlike the cultural underlying influences found in the banana industry, Cod is remarkably simple. Its found, its wanted, its consumed; repeat. Kurlansky claims the fish “changed the world” and while
There are many impacts that fishing and land animal farming have on the ocean, which are detrimental to ocean ecosystems as well as many other aspects of the environment. Overfishing, killing fish at a much quicker rate than the fish can repopulate, is one major problem. Three-fourths of the world’s fisheries are either fully exploited, overexploited, or depleted (Cowspiracy). Researchers have estimated an end of all viable fisheries by 2018 if the current trends of fishing continue (Mason). According to the Monterey Bay Seafood Watch, hundreds of thousands of animals die every year as bycatch, with one of the worst offenders being shrimp fisheries, catching up to six pounds of bycatch per pound of shrimp. Endangered species are also caught, including predators which are important in keeping the balance in ocean ecosystems (Smith). While many organizations such as the Monterey Bay Aquarium Seafood Watch recommend consumers to eat more “sustainable” fish, this will not stop the massive environmental impacts. Sustainable fishing for one does not account for the natural flux in the population of species of fish; what is considered a sustainable amount of fish to harvest one year may deplete the fishery in another year (Smith). Sustainable fish also are becoming even less sustainable as companies that label sustainable fish must find more For example, after Wal-Mart pledged to selling Marine Stewardship
We were all taught that our Earth is covered by seventy-percent of water. But did you know that there’s only two percent of our food sources come from the ocean? Today, I am standing here to propose the importance of opening up 2 new open-net salmon farms in British Columbia. I am a managing director from an international salmon producing company Marine Harvest. I am going to present you the economic, environmental, and social benefits of new salmon farms.
The availability of saltwater fish products in the market was depend on the coastal fishing vessels operation. One species that is widely consumed around the globe is Tuna (Thunnus sp.). Tuna is widely available both in Pasific and Atlantic ocean. The nutritional content of tuna, both bluefin tuna and yellowfin tuna according to the USDA National Nutrient Database can be seen in Table 1 (1). Fish nutritional composition is varied between species. It is likely the variety of nutritional composition were based on gender, age, season, water temperature, type, and abundance of available food (2). Recent fisheries study indicated that fishing method can impact the freshness of cod flesh (3). Those fishing methods including haul size, haul duration, and direct gutting before storage period. Olsen et al. (2013) also concluded that the fishing method will affect the muscle pH, blood pH, glucose and lactase concentration during rigor period (3). It is likely those factors also responsible for the number of microflora in saltwater fish flesh.
To fish or not to fish is a personal choice. The fact that the oceans are being overfished is a growing concern for individuals, organizations, and governments throughout the world. In this paper I want to discuss the effects of overfishing on the restaurant industry, and possible solutions to solve the problem. Fishing is an ongoing source of food for people around the world. In many countries it is a food staple in their everyday diet. In more modern societies eating fish has become a sensual experience, and not just for the wealthy. It hasn't been until population explosions in the last century that the demand for seafood has led to more effective fishing techniques and technologies. Now the demand for popular fish like the salmon, tuna, sea bass, cod and hoki, which is the key fish in McDonalds filet o' fish, is diving wild populations to dangerously low levels. The methods used to catch the amount of fish demanded by the industry do not leave sustainable populations in the wild. In an attempt to preserve the fish population, governments have set limits on the minimum size that may be harvested and how many of each may be taken. Boundaries have been set up saying which areas can be fished and which ones should be left alone. A number of smaller fisheries have gone out of business because of the limits imposed by the government. This leads to even less fish being harvested and brought to market. Therefore the amount and varieties of fish at markets are smaller and can cause shortages for wholesalers and restaurants. Some restaurants will no longer have the variety on their menus that they used to enjoy. If a restaurant thrives on its seafood menu they may be unable to cope with the shortages and will go out of business. In the ...
Fishing and harvesting of seafood have been a part of our society, and over the last few decades, it has skyrocketed in sales throughout the United States. In fact, in 2006 there were about 30 million people in the United States alone that engaged in recreational fishing. Seafood harvesting includes locally caught, imported, aquaculture knew more commonly as farm raised. In 2013, the amount of fish and shellfish harvested from the wild was about eight times greater than the amount of seafood produced by the domestic aquaculture farms.
Overfishing is a harmful practice, that will eventually lead to the collapse of aquatic ecosystems, if it’s not dealt with promptly. Overfishing emerges from the combination of our over consumptive society mixed with the great profits that come from hauling in a good catch. The consumers demand for fish in Japan seems to be at an increasingly high rate due to the enjoyment and cultural values that arise from sushi and other traditional dishes involving seafood. Approximately 23 percent of Japan’s protein intake comes from the ocean, and as a nation consumes 7.5 million tonnes of seafood annually. CITATION
According to FAO (2008), the world fisheries production by capture and aquaculture has reached 142 million metric tons which this number shows the increasing of about 26 million metric tons from the fish production in 2007. FAO reported that the scale of fish capturing has reached the maximum level and it was counted that about 77% of the fishing region in the world has now classified as fully exploited. As this scenario might cause the decreasing of new fish sources, the fishing industry will face some problems to fulfill the demand of this protein source around the world (Meryl 2007). As a result, the fisheries industry has now actively develop the aquaculture industry to make sure that the production of this protein source will meet the world demand. In contrast to the production rate in 1970 that recorded about 15.5% of fish production, the percentage is now increasing to 32.4% in 2004 and 36.93% in 2008. This show the encouraging of increasing through the year with average 7.1% per year thus show a good potential to be expanded around the world including Malaysia.
Overfishing is the most major problem related to oceans, but it is also the most overlooked. Fishing has been going on for thousands of years, and fish have always been seen as a renewable resource, that would replenish itself forever for our benefit. But around the world there is evidence that fish are not recove...
Fish is a great source of protein and provides people their basic dietary needs on a daily basis. According to the Huffington Post, 1 billion people around the world rely on fish as their man source of protein. But this also comes at a cost. “Due to overfishing, over 70% of the world's fish are either fully exploited or depleted.” Luckily, fish farms have stepped up and have become a major part of how we obtain fish in our diets. They take very little space, they can be controlled, and they provide large numbers of seafood rather than having to deplete natural stocks of fish. With growing concerns of dropping numbers of fish in the wild, solutions like fish farms have given us alternatives to harvesting fish. They allow us to monitor fish throughout their lifetime, allowing us to increase their chances of survival while also creating an abundance of fish to keep up with global demands that continue to rise every day.
The Michigan Aquaculture Association (MAA) represents producers of fish and seafood that are grown in a safe and environmentally delicate manner. The MAA supports and promotes a well-developed and sustainable aquaculture industry in the State of Michigan, through building partnerships between the industry, universities, public agencies, and consumers (Michigan Aquaculture Association, 2009). Current Michigan aquaculture activities focus on raising fish for use as bait, stocking ponds, fee fishing, and food. The major focus used to be on producing sport fish for stocking and fishing pursuits, changing population demographics and greater consumer interest in healthy diets point to future growth in producing fish for human consumption (Michigan Aquaculture Association, 2009).
