IN BRIEF - Talk on fast disappearing tuna fishing culture
Thursday, June 14, 2018
Tuna fish and Malta and Sicily’s fast disappearing ‘tonnaroti’ (fishers of tuna), together with their stories, songs and handicrafts, is the theme of a talk that Gaetano Malandrino will deliver this evening as part of the Magic Box series.
His talk, entitled ‘Di tonni e tonnare. Tra Sicilia e Malta’, revolves around this fish species, which is coveted for its delicious meat, and lives along the coasts of the Mediterranean in an eternal struggle with ‘tonnaroti’, as well as about the hard life of Sicilian and Maltese traditional tuna fishermen.
Malandrino, an architect, writer and lecturer of History of Art in Florence, is originally from Noto, Sicily, and considers Malta his second home. He will animate his presentation with photos of coves and hidden bays, as well as songs and interesting tuna recipes.
Over 300 researchers, practitioners, small-scale fishers, civil society organizations, environmental organizations, and government representatives will gather next week to discuss transdisciplinary strategies to sustain small-scale fisheries as a global food production system, as part of the 3rd World Small-Scale Fisheries Congress.
Taking place on 22–26 October 2018 in Chiang Mai, Thailand, under the theme ‘Transdisciplinary and Transformation for the Future of Small-Scale Fisheries’, the congress aims to facilitate information exchange, knowledge sharing, and discussion among participants who come from more than 50 countries for the viability and sustainability of small-scale fisheries worldwide.
Small-scale fisheries provide food for billions of people and livelihoods for millions. Yet these services are being affected by factors such as ineffective governance, inequitable fishing rights, climate change and competition for space and resources with large-scale industrial fisheries and other sectors. In many instances, social, policy and governance transformations have taken place in response, but these are not always favorable to small-scale fisheries. Careful considerations are therefore needed to promote positive outcomes and avoid harmful ones.
Northern anchovies are no ordinary fish. Found off the coast of California, these small, nutrient-rich fish have been identified by scientists as the most important prey for dozens of other marine wildlife species—from albacore tuna and chinook salmon to least terns and humpback whales. When it comes to the Pacific Ocean food web, anchovies truly are one of a kind.
Beyond their vital role in West Coast marine ecosystems, anchovies stand out for another reason. They are one of just a handful of Pacific Ocean species that are managed with fixed catch limits based on decades-old information. This means fishery managers essentially “set it and forget it” when it comes to anchovy fishing limits, and that can put the species and its predators at risk. So even if the anchovy population rises or falls dramatically over just a couple of years—which is precisely what this species does naturally—the amount of fish that can be caught by commercial boats remains unchanged.
For example, the current catch limit for California’s anchovy population has been on the books for two decades and is based on information collected between 1964 and 1990—data that have no bearing whatsoever on today’s population. This approach can work when anchovy numbers are high. But when the population collapses, as it did between 2009 and 2016, failing to lower the catch limit can put anchovies and the wildlife that depend on them for food at risk.
KOTA KINABALU - There will be no more mangrove lands approved for shrimp farming in Sabah, says Datuk Junz Wong. The Sabah Agriculture and Food Industries Minister said mangrove destruction for whatever purposes must be stopped for conservation.
“The destruction of valuable natural environment assets are irreversible, therefore instead of destroying the environment for wealth, we should promote and encourage agricultural economic development,” he said during a visit to the Pitas Shrimp Farm at Sungai Telaga in Pitas.
Wong urged prawn farmers to go upstream to create hatcheries, as well as downstream for prawn export.
A database of larval fish collected over the last three decades and analysed by UNSW researchers will help scientists assess the effects of climate change on the health of Australian fisheries.
In a paper published today in Nature’s Scientific Data journal, researchers show how the database provides the seasonal dynamics of larval fish in temperate and subtropical Australian waters since the 1980s.
Larval fishes are a pragmatic way of measuring marine ecosystem state and change, as well as species-specific patterns in seasonality. The high level of taxonomic expertise required to identify larval fishes to species level, and the considerable effort required to collect them, make these data extremely valuable.
The INvertebrateIT project is pleased to announce an open call to all stakeholders in aquaculture to collaborate with three forward-thinking small to medium-sized enterprises (SMEs) on several promising invertebrate-based feed solutions.
The SMEs were selected to receive support from INvertebrateIT as they showed high potential for addressing the sustainability of feed, a key challenge facing aquaculture. Through partnerships with leading industry stakeholders, it is hoped these innovative ideas can be transformed into market-ready products and offer a viable solution to these challenges.
Typical fish-based feeds are the single highest cost in aquaculture farming, and increasing demand, price volatility and impact on natural resources are limiting the industry’s growth and sustainability. For a growing global population eating more seafood than ever, other resources must be exploited. Increasingly, invertebrates such as flies, worms and small crustaceans are providing a sustainable and plentiful alternative to the resource-hungry raw materials that are otherwise commonly used. These invertebrates provide a rich source of essential proteins and oils that can provide the nutrients required for farmed fish.
There’s a difference between living a long life and living a long healthy life — not just surviving, but thriving in old age without any major illness or disability.
New research suggests eating more seafood could play a role in making that happen. Among older people, having a higher blood level of omega-3 fatty acids found in fish was associated with a lower risk of unhealthy aging, a study published Wednesday in The BMJ found.
“We should think about how to increase that level in our body,” lead author Heidi TM Lai, a postdoctoral fellow at the Friedman School of Nutrition Science and Policy at Tufts University, told TODAY.
“We’re living longer burdened with disease so as researchers, we want to start to focus on the quality of life and not just longevity.”
ELLSWORTH - Shrimp fishermen - the few that are left, anyway - will be able to weigh in on a proposed change to the rules governing the fishery tentatively approved by the Atlantic States Marine Fisheries Commission.
Meeting in Portland earlier this month, the ASMFC’s Northern Shrimp Section approved, subject to public comment, an “addendum” to the current version of the Northern Shrimp Fishery Management Plan.
The addendum would allow each of the three states that have shrimp landings - primarily Maine but also New Hampshire and Massachusetts - to allocate their annual catch quotas between the types of gear used in the fishery.
In the last years that there was a commercial fishery - there has been a moratorium on fishing since 2013 - trawlers caught about 90 percent of shrimp landed but there was a growing trap fishery.
Dolphin deterrents, turtle excluders and bird bafflers are all at work in the nation’s fisheries in an effort to protect many sea species.
The latest report on Australia’s 95 fishing species noted good progress in protecting species such as sea birds, turtles, seals and sea lions during commercial fishing of wild stocks.
“All vessels in the … fisheries must use sprayers, bird bafflers or pinkies - large floats attached in front of trawl warps to scare birds away, combined with zero discharge of fish waste,” the Australian Bureau of Agricultural and Resource Economics and Sciences Fishery Status Report 2018 said.
Scientists at the University of Stirling have challenged concerns around the consumption of imported farmed shrimp – with new research indicating that it is as safe as any other seafood product.
Experts observed the findings after using European Union (EU) data to perform a risk assessment on shrimp imports, which have a reputation among some consumer groups as being of low quality.
Professor Dave Little and Dr. Richard Newton, of Stirling's Institute of Aquaculture, working with colleagues at Shanghai Ocean University, also found that shrimp imports have become much safer to consume in recent years. The findings of the research are published in the Aquaculture journal.
