At times, 80-90% of the whole catch may be non-commercial fish, that are killed and thrown back into the ocean, mainly dead. This happens because some fishermen are careless, and do not know where the fish they are meant to catch, causing them to catch fish that are not commercial. Others may think that if the fish is not a “food fish” then it is released back into the ocean, and it will live. This is not true because by the time the fishermen get around to collecting the fish they want, most of the fish are already dead. They may throw back a few fish, but those will most likely die, or become quick food for a predator.
After destroying one ecosystem, the fishermen would typically move to the next disregarding the impact they are leaving behind. Some species would go to remote areas to rejuvenate. However, now in modern times no place on Earth is now too remote for today’s industrial fishery fleets. Without giving stocks the proper time to recover from that, the stocks will continue to deplete and it heightens the possibility of losing the marine life that many people are so dependent on. Ever since Native Americans have settled in the Pacific Northwest, sSalmon have been a big part of their culture.
This has caused the majority of sea turtles to be endangered. As you can clearly see, this has put a huge effect on sea turtle’s lives. Although many of them have been killed, they aren’t the only ones affected by this. Many other fish spices have been hit. Salmon sales have gone down because they’ve been dying.
The collapse of the marine ecosystem would result in the a massive amount of loss in fish stocks, resulting in the loss of business and the starvation of many people around the world that rely on fish as their major supply of food. (The main cause of overfishing is large fishing companies
Holding the boats just days before the season starts, and the accumulating cost of sitting at the docks, has frustrated many boat owners. Keith Colburn, the owner of The Wizard, told fox reporters that the government shutdown really cut down on the profits of these fishers. He says that the main buyers of the crabs are the Japanese markets during the holiday seasons. And that they have to get the crabs to Japan by November, or they risk missing out on the main portion of their sales (Deadliest Catch's' Keith, 1). If the Japanese do not get their crabs by that time, then they will gladly go to the Russian market, which has been clouded by questionable practices.
There are many reasons for this problem which include environmental degradation, evolving fishing technologies and its associated increased capacity, overfishing and etc.In the coastal parts of Southeast Asia the fishing stocks have already exhausted to an alarming levelranging from 5 % to 30% of unexploited levels. The significant increase in the shipping vessels has also greatly impacted the local catch. However during the years 1993 to 2007 a number of fishing boats/ trawlers were added by the fishermen of both Sindh & Baluchistan, but were not able to yield the expected return even though the catch included the Exclusive Economic Zone (EEZ), extends to approximately 200 miles deep from the coast. Another major reason for the drop in our fishing catch is the increase of Int’l fishing vessels which the govt. of Pakistan fails to address todate.
The reason for this is that The decline of the fish wealth that caused by illegal fishing is affecting badly million of people in the world who are depending on the fish and sea creatures and benefiting from them to survive . For example people who are living in the developing countries and in the costs especially in south Africa are depending on the fish and the sea to feed them self are suffering from the illegal fishing, because they are getting important micronutrients from the fish such as vitamins , calcium , zinc , fatty acids and it protect their bodies from the diseases but with the decline of the fish wealth their health has been affected , because they are not getting enough micronutrients and energy ( Golden & Allison , 2015 ). Moreover the bad storing of the fish is one of the most important reasons that can affect the human health. the fishers who are practicing illegal fishing are covering the surplus of fish in places that are inappropriate to save fish in it to hide their crime against the marine environment ( Beke & Blomeyer , 2014 ) . Consequently this thing causes a lot of diseases between the fish that can transfer to the human and affect their health’s such as Heterophyiasis disease that affect the human stomach, salmonella and candida fungus that causes severe infections in some parts of the body (Golden & Allison , 2015
For several years now, Illegal fishing has been a major problem in the growth of marine sector in Indonesia. Furthermore, the majority of the malpractices are done by neighboring countries such as Thailand, Vietnam, Malaysia, RRC, Filipina, etc. In addition, the numbers of illegal fishing is quite massive. According to FAO (2008), approximately there are 1 million ton of fish fished illegally by 3000 ships annually. Due to IUU, Indonesia suffers Rp 30 trillion annually based on FAO and Indonesia suspected higher number then that which is Rp 300
Shrimp farming is one of the aquaculture practices that cause huge losses of mangrove habitats. Recently the worst cases recorded in Ecuador, Indonesia, and the Philippines compared to the other several countries (Bandaranayake, 1999). Naito & Traesupap, (2006) identified that for the destruction of mangrove forest in Thailand shrimp farming is the main causes. And also they identify the development of extensive and semi-intensive shrimp farming techniques quickens mangrove deforestation than the intensive shrimp farming. Harkes et al (2015), indicated that losses of mangrove forests are increasing the coastal vulnerability to climate
They are caught in nets through trawl and long-line fishing. Dynamite fishing blows up their food sources. They are deprived of nesting sites when sandy areas are converted into beachside condominiums, and their eggs are harvested indiscriminately, leaving few to hatch and replace the current population. The decrease in egg production of green turtles has ranged from 65% to 90% in different parts of Southeast Asia between 1930 and 1993. The region, in fact, is considered the world’s greatest consumer of turtle eggs.
