Moreover, numerous unwanted fish and sea animals die unnecessarily in the course of the fishing process annually. Thus, it is worth reiterating that unsustainable fishing is one of the biggest threats to sea animals and its continuation could possibly drive these species to near extinction. Notably, the extinction of sea animals could have a destroying effect on the food security, income, and even livelihood of many people who depend entirely on oceanic resources. Thus, humanity ought to embrace sustainable fishing practices. In addition, shark finning and whale hunting also
Hence, overfishing threatens coastal nations down to the local level, devastating communities whose dominant sources of labor and revenue hinges on healthy, plentiful stocks of fish. Also, marine life imbalance may affect the targeted fishing of top predators such as billfish, sharks and tuna that eventually disturbs marine communities. In fact, it is causing increased abundance of smaller marine animals at the bottom of the food chain. This in turn has impacts on the rest of the marine ecosystem, such as the increased growth of algae and threats to coral reef health. Overfishing is also closely tied to by catch, another serious marine threat that causes the needless loss of billions of fish, along with marine turtles and
They grow slowly and take a long time to mature. They also have relatively low rates of reproduction. This means that their populations can’t recover quickly if they are being killed often enough. Over-fishing, never mind culling has now become a worldwide problem. If the sharks are removed it would cause the prey population to grow and eventually die out due to starvation.
The definition of over fishing is to deplete the number of fish in a body of water by too much fishing. Overfishing is very harmful to the ecosystem, taking a species close to extinction or completely extinct. As a species gets close to extinction it can be very hard to restore them back to sustainability. Even closing the fishing game for that species is not enough for a species to comeback from overfishing. Both recreational and commercial fishing have a huge impact on overfishing, by keeping under sized fish and other aquatic life.
The Cultural Effects of Coral Bleaching Located in warm, shallow waters, one species is near it’s extinction. Scientific studies has anticipated this for years, but many people do not understand the _damage this obsolescence would have on the environment. An essential animal in the ocean, coral, is, “home to 25% of all marine fish species,” according to The Reef Resilience Network, which specializes in helping save coral. Corals have very special tolerances to things like temperatures, salinity levels, and pollution, which causes coral stress, or bleaching. When bleaching occurs because of the unsuitable conditions, the corals expel the algae living in them, turns white, and dies, When corals die, thousands of sea creatures living around reefs
Therefore they make a circle to protect their young. The Male Sperm Whale could easily kill an orca and has no other enemy then humans. Sperm Whales are big creatures and big creatures have to eat. The Sperm Whale feeds himself with Giant Squids, octopus, fish (The Sperm Whale eats 3% of his body weight every day). They are real squid killers however if they encounter colossal squids who can weigh up to 500 kg they need to struggle.
Sea turtles often eat plastic bags instead of jellies. This cost for turtle a life, as plastic causes a blockage within digestive system. But this is only the beginning. Spots made of plastic cover for Sunlight cannot penetrate through plastic garbage into the water, algae and plankton, which is the bottom of the food chain, may simply die out. The situation can quickly turn into a global crisis.
This hawksbill turtle is migratory animal and they are found in more than 60 countries, and also seen in the beaches of the UAE. About 80 per cent of the world wide population of this turtle decreased in the past century. According to the World Wide Fund for Animals (WWF), their study shows now day in the world almost 8,000 adult nesting females are left. The reasons of their decrease are lots of. Hawksbill turtles are much desired after during the whole of the torrid zones for their yellow and brown shells that are made into items of tortoiseshell items like ornaments and jewellery.
Whitfield). Lionfish act as predators and when they enter new locations there are not many predators that can control the lionfish population. As a result, fisherman in multiple areas in the Gulf of Mexico have used their motivation to help conserve the biodiversity of various populations of fish in the ocean. The fisherman uses their scuba diving gear and spear to capture and killing of lionfish (de Leon R et al.). If the market for lionfish grows exponentially, there can be a rise in popularity of consumption of lionfish.
The plastic industry is growing each year; the Global Plastics Market sees the industry to be worth 654.38 billion by 2020. Already 300 million tons of plastic is produced each year of which only 10% recycled. Due to the exorbitant amount of non-biodegradable plastics much of it ends up or is dumped in the oceans. Many types of these plastics will hold their shape for a thousand or so years, while others will break up into smaller pieces which often end up looking white and spherical which many oceanic creatures recognize as fish eggs. An estimate of 100,000 marine animals die each year from entanglement in plastic, not including death through digestion of plastic materials.
