Healthy Oceans And Sustainable Fishing

By Buddhika Ranadheera –

Oceans cover two thirds of world’s surface, and over 7.6 billion people directly or indirectly benefit from oceans around the world. Global fishery production is ever expanding, and according to the Food and Agriculture Organization (FAO), fisheries and aquaculture assure the livelihoods of 10-12 percent of the world’s population. Ocean resources can boost the growth of a country’s economy, but human activity also takes a toll on ocean health. Therefore, fishing needs to be carried out at sustainable levels, or fish stocks will deteriorate from overfishing and collapse. According to the World Wildlife Federation, if the world keeps fishing at its current pace, there will be no more fish left to eat by 2048.

Sri Lanka is no exception to these statistics. One third of the population is living in the coastal belt, and many livelihoods are dependent on fishing. According to the Sri Lanka Export Board, the fisheries sector has generated approximately 2.4 million direct or indirect jobs for Sri Lankans. As per the Centre for Environmental Justice, fish is the source of protein for 2.5 million people living in coastal communities, and it provides more than 50% of the country’s animal protein requirement. According to the 2016 central bank report, the fishing industry generates 1.6% of the Gross National Income. With a dependence on fish products for protein and a growing population, demand for fish is great in Sri Lanka as well. But even though it is necessary to expand the country’s fishing industry, it needs to be carried out at sustainable levels and with healthy practices.

Sri Lanka and its Bodies of Water

Sri Lanka is an island nation in the Indian ocean, and the surrounding waters provide it with ample access to a vast variety of ocean resources. Many landlocked nations depend on countries like Sri Lanka for marine resources including fish, ornamental fish, and seaweeds. With the lifting of the European Union ban on Sri Lankan fish exports, seafood exports to the EU have expanded significantly. According to the Central Bank report, fish exports to the EU increased by 23.1 percent to a total of 2,540 metric tons in 2016. There is a great demand for Sri Lankan seafood and Tuna in the US, Japan, and the EU. Apart from fish for consumption purposes, global demand for Sri Lankan ornamental fish is also high in the US, Japan, and EU markets.

According to the United Nations Convention on the Law of the Sea (UNCLOS), Sri Lanka has territorial waters extending 12 nautical miles (nm) beyond the coastline, covering an area of about 21,500 sq km. Additionally, Sri Lanka controls another band of water called the contiguous zone, which extends up to 24 nm from the the end of the territorial. In addition, the country enjoys rights to an ‘Exclusive Economic Zone’ (EEZ) that extends up to 200 nm from Sri Lanka’s shores and encompasses an area of about 510,000 sq km. Therefore, Sri Lanka has right to a body of water and its resources that is approximately seven times as large as the island’s landmass. Apart from those external water bodies, Sri Lanka also has 2905 km2of inland water bodies. Given the enormity of both internal and external water resources, Sri Lanka is a country with high potential to be self-sufficient in seafood as well as to expand its export market.

Threats to Sri Lanka’s Fishing Industry

On one hand, Sri Lanka is not taking  full advantage of its territorial waters to boost the economy; on the other hand, the current fishing industry is full of malpractices that destroy its own future. Fish stocks are affected by illicit fishing and illegal fishing methods, including banned nets, pair trawling, spear fishing, and dynamite fishing. Pair trawling or bottom trawling sweeps the entire ocean bed, thereby destroying the ecosystems, eggs, and breeding grounds of fish. This method catches not only the expected fish but also corals and marine life inhabiting the corals. The resulting bycatch is often wasted, resulting in imbalances in the ecosystem and rendering the entire industry unsustainable.

In addition, spearfishing in Sri Lanka targets the grown coral fish and has thus become a major threat to the existence of some of the endangered coral fish. The existence of these grown coral fish is vital to the survival of the coral reefs, as the coral fish devour fish that eat corals. Therefore, the biological imbalance generated by spearfishing will deplete the corals.

Moreover, small scale fishermen also use traditional illegal fishing gear called Hambili, Laila, and Surukku which affect the livelihood of fishermen and have contributed significantly to reduce the fish catch. All these fishing nets destroy the rich marine resources while also posing a threat to the mangrove environment. As the eye of these nets are smaller, tiny fish are also getting caught, which deprives bigger fish of food and thereby posing a threat to the sustainability.

Dynamite fishing is another menace to the sustainability of the fishing industry. Dynamite is thrown at an identified fish school, resulting in stunned and dead fish floating to the top where they can easily be caught. This dynamite fish is not good for consumption, as it contains explosives and has been in contaminated water for a considerable time, and instead poses a threat to corals and other marine species.

Besides these unsustainable fishing methods, poor fisheries management and large scale post-harvest losses due to poor handling are the major barriers on the way forward for Sri Lanka. Approximately 25% of the catch is wasted in the storage process of Sri Lanka due to unavailability of proper storage facilities in the fishing fleets as well as the ports.

Solutions for a Healthy Catch in Sri Lanka

For Sri Lanka, the proper handling of the catch as well as adequate storage facilities are vital in harnessing the full potential of the industry. The Fisheries Ministry should provide proper facilities to the fishermen, including harbour and storage facilities. Improved roads and infrastructure also ensure the transportation of fresh fish with minimum wastage. Technical know-how on proper fish packing procedures will also improve the quality of the fish and make them feasible for the export market.

The Fisheries Ministry should introduce new regulatory mechanisms for fishing methods and gear and enforce new regulations when issuing licenses to fishermen. Moreover, the government should ban bottom trawling and patrol Indian fishermen entering the waters of Sri Lanka, as their method of pair trawling destroys the sea bed. The Fisheries Ministry along with the National Aquatic Resources Research and Development Agency banned the Laila and Surukku nets in 2016. Providing fishermen with environmental-friendly nets with larger rings would be a bold step towards protecting the oceans. However, there is still a regulation under the Fisheries and Aquatic Resources Act that allows bottom trawling. Even though an amendment to the fisheries and aquatic resources bill was tabled in Parliament to ban bottom trawling and dynamite fishing, it has not been implemented so far. The government needs to ban bottom trawling immediately to save the diminishing ocean resources.

Moreover, the government should also introduce methods to reduce the bycatch or the catch of untargeted fish caught in the nets and dragged along for miles, as most of the fish simply die before reaching the shore. In addition, the Government should close certain areas for fishing to allow the damaged marine resources to recover.

Hence, for a sustainable fishing industry, several factors are essential, including a conducive environment, the availability of coral reefs, sand bars, and unpolluted internal and external water bodies to provide breeding grounds for marine species. It is the responsibility of everyone, not only fishermen, to protect ocean habitats and marine life to ensure that marine resources will still be available for future generations.

    Indian OCen is still relatively clean eventhough China to Europe sea rout is very busy with respect to eh North America to Europe route which is not much active now. Sri lanka’s probem is foreign trawlers catching fish. Tamilnadu Trawlers evend oing bottom cleaning. Even the fish linces that the govt gave I heard are catching even the small fish making young fish stockes dwindling. then the next probem is Portugal, French sishing trawlers cleaning the oceans. that doe snot need expensvie war ships. Instead the Existing anvy shipa can guard our areas. Sri lanka also can start ship building as there is some activity there. Even NAvy caninvolve in that.

    Hi, Wonderful work educating us all on a critical subject that should help the country recover well. Kindly consider the following please to complete your article…
    SL/India map showing territorial water, contiguous zone and the Exclusive Economic zone. Please also show the Indian zones and any overlaps, a paragraph on how SL and Indian navy protect each others interests in these zones, also capture the definitions of each zones regard to exclusive rights and shared rights etc, show on the map where most of the Indian fishermen are caught by SL Navy porching, is there any articles/observations regard to how much of illegal fishing pre/post war scenarios by the foreign fisherman undetected because it is not only the TN fisherman but extensively from the Eastern coastal regions of India further up north too may have been poaching for a long time, what was SL capacity to protect (not defence) poaching issues since Independence to date?, your difficulties resourcing information regards to SL historical records from the libraries, fisheries departments etc, referencing data/facts should always a good way to present a case as it will also list a good info for the readers and helps to build up your article more as required so it can become more useful referencing material in the future, is there any research and special case studies carried out by our universities on any of the issues you discussed in your good article?? what are the knowledge base of the respective local governments covering coastal areas on their capacity to support the industry or is it the scope of central government only?, What are the technologies available that can avoid any infighting within the coastal fishing communities specially when they feel even their fellow countrymen from different parts are steeling there share of the sea? Thank you.

    Sri Lanka is the worst polluter of the indian Ocean, see Groundviews 08/22/2012 Protecting Sri Lanka’s Ocean by Ranil Senanayake. Policy will not help unless enacted.

    What do you think about Glyphoste now 35 40 years flowing into the sea and aquatic warter resources. Reesidues can be absorbed into sifh. It is proven even human fetus can be killed by that. Maithripala srisiean govt think only about acute toxicity which can happen right away. What about the chronic toxicity which happen over the time. These are artificial chemicals that the nature is not evolved to break down.
