Eastern Atlantic Bluefin Tuna Threatened
An analysis of eastern Atlantic bluefin tuna trade data released Oct. 18 shows that harvests of the imperiled tuna are more than double the legal amount. This calls into question the National Marine Fisheries Service’s (NMFS) June decision, responding to a Center for Biological Diversity petition, that found bluefin were not endangered as long as there is a high degree of compliance with total allowable catch levels.
“Illegal fishing is rapidly pushing eastern Atlantic bluefin tuna to the brink of extinction. Rather than turn a blind eye to this ongoing crisis, the fisheries service needs to give this dwindling species the protection it needs to survive,” said Catherine Kilduff, a center staff attorney. “Endangered Species Act protections are necessary to stop U.S. imports from the Mediterranean and begin rebuilding this population, crucial to the health of the Atlantic Ocean and our fisheries.”
The Pew Environment Group report found that in 2010, the amount traded on the global market was 141 percent above allowable catch levels (32,564.9 metric tons). That doesn’t include black market bluefin missing from trade records. Discounting illegal fishing, the NMFS denial of listing for the bluefin determined that a 5 percent probability of extinction in 20 years is a reasonable threshold for endangered status. At catch levels of 30,000 metric tons, there is an 8.5 percent probability that less than 500 adult bluefin tuna will survive in 2030.
Highly migratory, warm-blooded fish, Atlantic bluefin tuna include two genetically distinct populations, one that spawns in the Mediterranean (the eastern Atlantic stock) and a much smaller population that spawns in the Gulf of Mexico (the western Atlantic stock). New analysis of the eastern Atlantic stock has implications for both stocks because of cross-Atlantic mixing. Capable of speeds higher than 55 mph, bluefin tuna from the Mediterranean traverse the ocean in a matter of weeks as early as age one. Overfishing means that fewer Mediterranean tuna reach U.S. waters.
“Skyrocketing consumer demand for bluefin tuna has driven overfishing and lax enforcement of international agreements,” said Kilduff. “After years of recognizing the problem, but not implementing a solution, the international community must ban trade until bluefin tuna populations rebuild.”
In August 2011 the center requested that the U.S. propose Atlantic bluefin tuna for protection under Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), the major international treaty on endangered species. CITES protection would ban cross-border trade in Atlantic bluefin, potentially improving compliance with catch limits. The next CITES meeting will occur in 2013.
In response to the decline of the bluefin, the center last year launched a nationwide boycott of bluefin tuna (visit bluefinboycott.org for more information). More than 25,000 people have joined the center’s campaign and pledged not to eat at restaurants serving bluefin tuna. Dozens of chefs and owners of seafood and sushi restaurants have pledged not to sell bluefin.
According to a McKinsey & Company report released last month, current bluefin harvesting levels are projected to drive the eastern Atlantic fishery to collapse between 2012 and 2015. If illegal and unreported fishing could be 100 percent eliminated, the fishery could recover by 2023. But impressively, if the fishery were to be completely closed, according to the report, it would recover within eight years.

Winter is supposed to be the best season for wind power – the winds are stronger, and since air density increases as the temperature drops, more force is pushing on the blades. But winter also comes with a problem: freezing weather.

Ice buildup changes air flow around the turbine blade, which can slow it down. The top photos show ice forming after 10 minutes at different temperatures in the Wind Research Tunnel.

While traditional investment in the ocean technology sector has been tentative, growth in Israeli maritime innovations has been exponential in the last few years, and environmental concern has come to the forefront.
theDOCK aims to innovate the Israeli maritime sector. Pexels<p>The UN hopes that new investments in ocean science and technology will help turn the tide for the oceans. As such, this year kicked off the <a href="https://www.oceandecade.org/" target="_blank" rel="noopener noreferrer">United Nations Decade of Ocean Science for Sustainable Development (2021-2030)</a> to galvanize massive support for the blue economy.</p><p>According to the World Bank, the blue economy is the "sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem," <a href="https://www.sciencedirect.com/science/article/pii/S0160412019338255#b0245" target="_blank" rel="noopener noreferrer">Science Direct</a> reported. It represents this new sector for investments and innovations that work in tandem with the oceans rather than in exploitation of them.</p><p>As recently as Aug. 2020, <a href="https://www.reutersevents.com/sustainability/esg-investors-slow-make-waves-25tn-ocean-economy" target="_blank" rel="noopener noreferrer">Reuters</a> noted that ESG Investors, those looking to invest in opportunities that have a positive impact in environmental, social and governance (ESG) issues, have been interested in "blue finance" but slow to invest.</p><p>"It is a hugely under-invested economic opportunity that is crucial to the way we have to address living on one planet," Simon Dent, director of blue investments at Mirova Natural Capital, told Reuters.</p><p>Even with slow investment, the blue economy is still expected to expand at twice the rate of the mainstream economy by 2030, Reuters reported. It already contributes $2.5tn a year in economic output, the report noted.</p><p>Current, upward <a href="https://www.ecowatch.com/-innovation-blue-economy-2646147405.html" target="_self">shifts in blue economy investments are being driven by innovation</a>, a trend the UN hopes will continue globally for the benefit of all oceans and people.</p><p>In Israel, this push has successfully translated into investment in and innovation of global ports, shipping, logistics and offshore sectors. The "Startup Nation," as Israel is often called, has seen its maritime tech ecosystem grow "significantly" in recent years and expects that growth to "accelerate dramatically," <a href="https://itrade.gov.il/belgium-english/how-israel-is-becoming-a-port-of-call-for-maritime-innovation/" target="_blank" rel="noopener noreferrer">iTrade</a> reported.</p><p>Driving this wave of momentum has been rising Israeli venture capital hub <a href="https://www.thedockinnovation.com/" target="_blank" rel="noopener noreferrer">theDOCK</a>. Founded by Israeli Navy veterans in 2017, theDOCK works with early-stage companies in the maritime space to bring their solutions to market. The hub's pioneering efforts ignited Israel's maritime technology sector, and now, with their new fund, theDOCK is motivating these high-tech solutions to also address ESG criteria.</p><p>"While ESG has always been on theDOCK's agenda, this theme has become even more of a priority," Nir Gartzman, theDOCK's managing partner, told EcoWatch. "80 percent of the startups in our portfolio (for theDOCK's Navigator II fund) will have a primary or secondary contribution to environmental, social and governance (ESG) criteria."</p><p>In a company presentation, theDOCK called contribution to the ESG agenda a "hot discussion topic" for traditional players in the space and their boards, many of whom are looking to adopt new technologies with a positive impact on the planet. The focus is on reducing carbon emissions and protecting the environment, the presentation outlines. As such, theDOCK also explicitly screens candidate investments by ESG criteria as well.</p><p>Within the maritime space, environmental innovations could include measures like increased fuel and energy efficiency, better monitoring of potential pollution sources, improved waste and air emissions management and processing of marine debris/trash into reusable materials, theDOCK's presentation noted.</p>
theDOCK team includes (left to right) Michal Hendel-Sufa, Head of Alliances, Noa Schuman, CMO, Nir Gartzman, Co-Founder & Managing Partner, and Hannan Carmeli, Co-Founder & Managing Partner. Dudu Koren<p>theDOCK's own portfolio includes companies like Orca AI, which uses an intelligent collision avoidance system to reduce the probability of oil or fuel spills, AiDock, which eliminates the use of paper by automating the customs clearance process, and DockTech, which uses depth "crowdsourcing" data to map riverbeds in real-time and optimize cargo loading, thereby reducing trips and fuel usage while also avoiding groundings.</p><p>"Oceans are a big opportunity primarily because they are just that – big!" theDOCK's Chief Marketing Officer Noa Schuman summarized. "As such, the magnitude of their criticality to the global ecosystem, the magnitude of pollution risk and the steps needed to overcome those challenges – are all huge."</p><p>There is hope that this wave of interest and investment in environmentally-positive maritime technologies will accelerate the blue economy and ESG investing even further, in Israel and beyond.</p>
