Around 99% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with over 95% belonging to the teleost subgrouping. Scientists agree that at current exploitation rates many important fish stocks will be removed from the system within 25 years. A typical marine conservation project can increase biodiversity by more than one-fifth and raise fish catches four-fold, the study showed. An estimated 70 percent of fish populations are fully used, overused, or in crisis as a result of overfishing and warmer waters. World per capita fish supply reached a new record high of 20 kg in 2014, thanks to vigorous growth in aquaculture, which now provides half of all fish for human consumption, and to a slight improvement in the state of certain fish stocks due to improved fisheries management. The End of the Line is a powerful film about one of the world's most disturbing problems: overfishing. Currently, less than 1% of the ocean is protected, although by 2020, the international community has agreed to raise this to 10%.

In 2017, fish provided more than 3.3 billion people with 20 percent of their average intake of animal protein. The effect is to make the oceans more hostile to life, with fish stocks likely to fall. The global share of marine fish stocks that are within biologically sustainable levels declined from 90 per cent in 1974 to 69 per cent in 2013.

Willie Mackenzie, of Greenpeace, said: "This report confirms the scale of the crisis our oceans are facing. Though nothing in the article surprises me, I Data from 4,713 fisheries worldwide, representing 78% of global reported fish catch, are analyzed to estimate the status, trends, and benefits of alternative approaches to recovering depleted fisheries. Stock assessments measure the impact of fishing on fish and shellfish stocks. The study is the biggest and most all-embracing effort yet to understand the productivity of the oceans and predict their future. This United Nations report examines the current state of knowledge of the world's oceans, for policymakers, and provides a reference for marine science courses. While – just as for the exact size of fish stocks – the precise extent of overfishing is by its very nature hard to determine, and different estimates exists, experts agree that it is a serious issue. ... to advocate for stricter management plans to help recover depleted stocks of tuna species. Overfishing is the removal of a species of fish from a body of water at a rate that the species cannot replenish, resulting in those species becoming underpopulated in that area.

Rather than having a system in which the EU members each hustle for the biggest quotas – which are already set far beyond what is sustainable – fisheries experts suggest individual governments should set quotas based on stock levels in their surrounding waters. All seafood will run out in 2050, say scientists. But there are fewer such healthy systems each year. A picture of food consumption (availability) trends and projections to 2050, both globally and for different regions of the world, along with the drivers largely responsible for these observed consumption trends are the subject of this review. Research shows that managing fisheries in this way means they are twice as likely to avoid collapse as open-access fisheries. Overfishing can occur in water bodies of any sizes, such as ponds, rivers, lakes or oceans, and can result in resource depletion, reduced biological growth rates and low biomass levels. Population dynamics describes the ways in which a given population grows and shrinks over time, as controlled by birth, death, and migration. Around 85% of global fish stocks are over-exploited, depleted, fully exploited or in … It's clear that fish and chips will be off the menu within our lifetimes if we don't act now.

Farms are stocked with wild fish, which must then be fed – larger fish like salmon and tuna eat as much as 20 times their weight in smaller fish like anchovies and herring. * According to the Food and Agriculture Organization of the United Nations, we must produce 70 percent more food to meet impending world hunger needs. It has been some time since most humans lived as hunter-gatherers – with one important exception. “Unless we fundamentally change the way we manage all the ocean species together, as working eco-systems, then this century is the last century of wild food,” says Steve Palumbi at Stanford University in California, US, who carried out the four-year investigation with colleagues. Preserving our pristine seas will boost biodiversity, replenish fishing stocks, and store carbon. As wild fish stocks decline, farmed fish is expected to take over. In Spain, for example, one in three fish landed is paid for by subsidy. Global fish populations are currently subject to severe stress from multiple causes including overfishing.

As a result, there are campaigns to ban aquaculture from coastal areas. It is 2050 1and the Ocean is thriving and abundant. Warmer waters are pushing species into different habitats, causing some to die off and others to adapt by creating entirely new hybrid species. But useful as they are, marine reserves – often around points like coral reefs or rock islands – are only effective if governments have the resources to patrol and protect them.

Also, many marine creatures, from whale sharks to whales, are migratory – they don’t stay in the protected areas, making them easy prey for fishermen. And the pace is accelerating.
