Lohithakshan and Girija smAcross the globe, the need for institutional mechanisms to address risk and uncertainties in the fisheries sector has intensified in the recent times on several counts. First, advancements in technology have resulted in escalation of investments, thereby deepening the economic risks associated with fishing and fisheries; second, climate change and resultant increase in the incidence of extreme weather events pose serious threats to the coastal inhabitants and their livelihood, mainly the fishing community; and third, capture fishing is inherently risky, with over 24,000 fisher folk casualties every year as per the estimates of the International Labour Organization, besides damages to craft and gear. Insurance is one of the widely accepted social safety net tools adopted across the world as an effective instrument for containing and mitigating a wide variety of risks such as asset risks, production and management risks, market risks, personal and health risks. Several variants of insurance products are in vogue in the fisheries sector such as accident insurance to cover the life/disability risks of fishing crew; vessel/ gear (fishing net) insurance to cover the damages incurred to fishing equipment; insurance coverage for coastal assets (houses and other immovable property) of fisher folk; aquaculture insurance to cover damages to crops due to disease incidence or other weather events, and so on. Insurance as a safety net is particularly important in developing coastal economies as they are predominantly small-holder oriented, supporting the livelihoods of a significant number of resource poor coastal inhabitants, for whom shock-absorption mechanisms during difficult times are crucial for survival.

Study area mapA recent study1 we and our colleagues conducted throws light on the level of adoption of various types of insurance by the fisher folk in the coastal belt of India. The study illustrated that risk financing behavior of Indian fishermen is notably low except in a few areas and that a number of constraints contribute to the prevailing state of affairs.

Based on a primary survey conducted across selected maritime states of India in 2016, an assessment of the adoption of various types of personal/group accident insurance schemes revealed interesting insights. On the positive side, adoption of personal/group accident insurance was fairly high in the states of Kerala and Tamil Nadu, with over 80 per cent of fishermen covered in the former. On the other hand, none of the respondent fishermen were insured in Andhra Pradesh, despite it being a state with a high incidence of extreme weather events. The states of Gujarat and Odisha were no better with only large landing centres well served, leaving out the majority of smaller ones.

The level of adoption of vessel insurance was also not found to be better. Except in the case of large landing centres where influential boat owners’ associations operate their own insurance programs using revolving corpus funds collected from fishermen, the coverage of vessel insurance is hardly satisfactory across the maritime states. Insurance coverage of fishing nets is even worse with most of the fishermen having opted out of it irrespective of region. In the same vein, household asset insurance coverage against unforeseen natural disasters, to which most of the coastal families are routinely exposed, is reported to be minimal.

What are main factors that hold back Indian fishermen from accessing insurance coverage for themselves and their assets? The study indicates that the main factors are lack of awareness of risk management solutions, a low resource base making available risk management options nearly unaffordable, and lack of confidence in claim settlement procedures.

On the part of the insurance industry, besides high risk perception, the dissuading factors are profitability concerns, high chance of moral hazards (e.g., greater risk taking behavior by those insured) and lack of adequate data about disaster risks. As enrollment by fishermen is lower due to the above reasons, the insurance companies have limited options to develop products that are affordable. The private insurance industry seems to have stayed back, citing the low interest of fishermen, poor demand for insurance, low profitability, high risk involved and high moral hazards. The study however emphasizes the need for catching up with rest of the sectors, as the investment stakes in fisheries have gathered weight in recent times.

We, however, are optimistic about the scope for reforming fishery insurance in the country through concerted efforts. In our study, we indicate the need for inculcating a risk financing culture in the coastal areas with the help of social campaigns. Ensuring the participation of grass-roots level organizations (fishery cooperatives/NGOs/boat owner associations/producer associations) as intermediaries or partners for insurance administration would be helpful to strengthen grass root level support services. Micro-level enrollment could be catalyzed by deploying a brigade of rural insurance agents/service providers. Bundling micro-credit with asset/disaster insurance programs is another sensible option to enhance coverage of schemes in areas where self-help groups have an active presence. To enhance affordability of fisher folk to insurance products, flexible options such as payment of premium in installments may be introduced. Another alternative is to bring in the provision of compensating for partial damage of fishing vessels. Presently, this is not on offer. New products in hitherto un-serviced areas like cage culture, seaweed farming and mussel culture could be thought of. The government should strive towards developing adequate dispute settlement mechanisms to address grievances, besides taking measures to increase competition in the insurance sector by incentivizing the entry of new players. Some of the existing unhealthy subsidies may be reallocated towards incentivizing greater insurance coverage. A certain degree of legislative coercion in the form of mandatory insurance coverage in selected enterprises may be also considered to enhance adoption.

Flood damage in GothuruthTogether with governance reforms, technology can play a vital role in improving efficiency, bringing transparency and reducing moral hazards in fishery insurance. Innovative products such as weather-index based insurance schemes are already in force in the agriculture sector, wherein, satellite data and inputs from weather stations are being used to trigger insurance payments in case of occurrence of weather related events. These can be extended to the fisheries sector as well, to increase efficiency and simplify procedures. The inputs from such platforms could be used for compensating damages to coastal assets of fisher folk, marine cages, and other fishery-related infrastructure. Similarly, advanced vessel monitoring systems (VMS), which are presently in the pipeline to be introduced in India, could be used to track the fishing vessels and assess incidents such as mid-sea capsizing and collisions. Such data would be valuable for the insurance companies to verify insurance claims by affected beneficiaries. Further, interactive ICT tools and mobile applications could be leveraged for speedy processing of insurance claims as well as for real-time assessment of damages incurred to fishing vessels and mariculture units in case of calamities. Over and above these, long-lasting efforts to improve the socio-economic conditions and living standards of the fishing community through development programs can complement the greater use of insurance.

GA 010 Alita-cropAsiaPacific-FishWatch's Sustainability pages for 6 Western and Central Pacific and Indian Ocean tuna species – covering 12 stocks – have been updated. By current assessments, the outlooks, tempered by management measures being taken, show:

  • Skipjack tuna: outlook remains unchanged since previous reviews. Compared to our update last year which showed 5 skipjack fisheries certified by the Marine Stewardship Council, now 8 fisheries have become certified, including some of the previously certified fisheries achieving re-certification. LINK
  • Yellowfin tuna: The status of both stocks is unchanged with Indian Ocean stocks overfished and overfishing occurring. Although the Western and Central Pacific stock is not overfished, concern is expressed over fishing pressure and bycatch by some fishing gears. The number of certified yellowfin tuna fisheries has risen from 5 last year to 11 presently. LINK
  • Bigeye tuna: Although not yet considered overfished, the latest assessment for the Western and Central Pacific Ocean stock continue to express concern that the stock is in a more depleted state than other stocks in this region, and bycatch is a problem with some gear. No bigeye fishery has been certified, but one combination yellowfin and bigeye tuna longline fishery was certified in late 2018. LINK
  • Albacore tuna: None of the three stocks (Northern Pacific Ocean, Southern Pacific Ocean and Indian Ocean) are considered overfished but concern is expressed at the fishing pressure on the Northern Pacific Ocean and the Indian Ocean stocks. One additional fishery on the Southern Pacific Albacore stock was certified in 2018, bringing the total certified certified fisheries to 9 for all three fish stocks. LINK
  • Longtail tuna: Stock assessments and catch data remain incomplete. Recent Indian Ocean assessments consider the stocks overfished and that overfishing is occurring. This species is within the management mandate of the IOTC but not the WCPFC. LINK
  • Pacific bluefin tuna: This stock is considered overfished and overfishing is occurring. The rebuilding plan will be kept under more constant review from 2019. A slow recovery is underway but the stock is still near an historically low level. LINK

These updates owe a big debt to the stock assessment experts and reviewers associated with regional fisheries management and technical organisations (SPC, WCPFC, IOTC, ISC, IATTC and the national body members of committees) and to the International Seafood Sustainability Foundation for its regularly updated overviews of stock status (see the latest Stock Status Report at: https://iss-foundation.org/about-tuna/status-of-the-stocks/).

We have updated the Sustainability pages in our 6 tuna species profiles in the Western and Central Pacific Ocean and the Indian Ocean. Check out the profile pages to get the current situation.

  • Skipjack tuna: Essentially unchanged status since previous reviews.
  • Yellowfin tuna: Unchanged status, and concerns for the state of the Indian Ocean stock remains; for Western and Central Pacific Ocean stock, fishing pressure is considered heavy and little or no room for greater effort; environmental concerns due to bycatch remain for several fishing gears.
  • Bigeye tuna: The latest assessment for the Western and Central Pacific Ocean stock is that it is not overfished but concern is expressed as the stock is in a more depleted state than other stocks in this region.. Several fishing gears cause bycatch problems. Check out our new pages on bigeye tuna  Production and Supply Chains & Markets.
  • Albacore tuna: None of the three stocks (Northern Pacific Ocean, Southern Pacific Ocean and Indian Ocean) are considered overfished but concern is expressed at the fishing pressure on the Norther Pacific Ocean stock. Check out our new pages on albacore tuna Production and Supply Chains & Markets.
  • Longtail tuna: Stock assessments and catch data are incomplete and concern has been expressed over the status of the stocks . Recent assessments consider the stocks both overfished and that  overfishing is occurring. This species is within the management mandate of the IOTC but not the WCPFC.
  • Pacific bluefin tuna:  This stock is considered overfished and overfishing is occurring. The rebuilding plan will be kept under more constant review from 2019.

Once again, a big debt is owed to the stock assessment experts and reviewers associated with regional fisheries management and technical organisations (SPC, WCPFC, IOTC, ISC, IATTC and the national body members of committees) and to the International Seafood Sustainability Foundation for its regularly updated overviews of stock status (see the latest Stock Status Report at: https://iss-foundation.org/about-tuna/status-of-the-stocks/

In recent years, international meetings on managing the Pacific bluefin tuna (Thunnus orientalis) and seafood auctions for this species have sparked headlines, such as those below, advocating urgent action to reduce overfishing or exclaiming at the astronomical prices for a single large fish.

The fishery for Pacific bluefin tuna is in serious trouble, more so than for any other tuna, even the other bluefin tuna stocks (for a summary, see the ISSF Status of the Stocks Report). The wild population of Pacific bluefin tuna is officially overfished, and overfishing is still going on.

AsiaPacific-FishWatch has produced an authoritative profile of Pacific bluefin tuna that will help you navigate the complex profile of this species. We cover its stock status, how it is produced from fishing, ranching and closed life-cycle aquaculture, what we know about who produces it, and how its eaten, as well as it basic biology and how it is affected by the environment and climate. The profile has been developed and reviewed by experts.

Here are some key facts from our Pacific bluefin tuna profile, although much remains to be understood about this species. Please visit the whole profile on this link:

  • Pacific bluefin tuna is economically and ecologically important due to its high market value and its role as a large predator in pelagic ecosystems. It is highly migratory and very widely distributed in the Pacific Ocean, seasonally inhabiting subarctic, temperate, and tropical waters in the North Pacific Ocean, and temperate waters in the south around Australia and New Zealand. It also undertakes large vertical movements.
  • Pacific bluefin tuna has only one stock and spawning has only been recorded in the north western Pacific Ocean. It is the second largest of all the tunas. Only the Atlantic bluefin tuna (Thunnus thynnus) is larger. Until 1999, Pacific and Atlantic Bluefin tuna were considered the same species.
  • About 14,000 tonnes is caught from the wild per year, most in the Western Pacific Ocean. Many of the smaller Pacific bluefin tuna are caught live in coastal waters, and taken to coastal cages in Japan and Mexico, and grown out, adding weight and value to the wild catch. In 2002 in Japan, the life cycle was closed in captivity and a small amount of production now comes from full aquaculture. Pacific bluefin tuna is caught both as targeted catch and as non-targeted bycatch, by many different fishing methods, including by several types of small-scale Japanese fisheries.
  • Pacific bluefin tuna is managed jointly by two tuna Regional Fisheries Management Organisations (RFMO), namely the Western and Central Pacific Fisheries Commission (WCPFC) and the Inter-American Tropical Tuna Commission (IATTC) and their country members. Given the concerns for the status of the stock and its fisheries, environmental non-government organizations have campaigned for much stronger catch restrictions.
  • The Pacific bluefin tuna stock is assessed as overfished and subject to overfishing. The 2016 stock assessment from the International Scientific Committee for Tuna and Tuna-like Species in the North Pacific Ocean (ISC) estimated that the spawning stock biomass was 2.6% of its estimated unfished level.
  • Pacific bluefin tuna is a most prized commodity in the sashimi market.
  • Under global climate change predictions, the relative abundance, spatial distribution ranges, and predator-prey dynamics in food webs of Pacific bluefin tuna are expected to change in response to altered oceanographic regimes that govern life cycle and seasonal movements.

The profiles have been written by Victoria Jollands and peer reviewed by many experts. Information has been drawn from peer reviewed sources which are given for each page of the profile. See Contributors and Reviewers for details and acknowledgements.
