Today on international women's day 2018 we collectively acknowledge and celebrate women's achievements throughout history and across nations. It is also known as the United Nations (UN) Day for Women's Rights and International Peace. Absolutely a day for shared and international celebration.
Throughout history and across the world women have fought and continue to fight for equality. We are the individuals, mothers, grandmothers, great grandmothers, sisters, aunties and wives who support ourselves, our families, our friends, our countries and our planet for the most part with quiet affection and definitely not for reasons of recognition or wider acknowledgement.
But it is important to recognise and acknowledge the role and achievements of all women, particularly those who are the silent backbone of their communities, where neither support nor recognition is widely offered. I could choose any number of amazing women to focus on here but would like to, very briefly, just draw attention to the women who play a significant yet quiet role in the world's fisheries.
Women play a significant role in fisheries across the globe
Women (and children) are key providers for their families and communities across the globe though the work they do gathering seafood for food and for income. The fisheries involving women and children are generally low tech with minimal or no gear often where seagrass and reef flats are 'gleaned' by hand at low tide to collect valuable invertebrates (and sometimes fish) for food and for sale. These women and these fisheries remain ill acknowledged and unsupported by local, regional or international efforts to manage and maintain the sense of food security that they convey. But they make up a significant proportion of the small-scale artisanal fisheries that collectively contribute up to one quarter of the total global catch. These women work tirelessly to maintain a way of life or simply to provide protein and nutrition for their families. These are voices that need to be heard and have a significant role to play in the management and maintenance of local scale fisheries.

These often ignored fishers can teach us all a lot about a lot of things, their ecological knowledge, dedication and hard work is something we could all learn from.
So this year I would like to celebrate and acknowledge these women on this important day.
I would also like to acknowledge and celebrate the amazing women who have always worked hard, led by example, encouraged (without question) and helped shape my own life ('no matter what'). I am privileged to have and to have had these women in my life.
Happy International Women's Day!

At least 7.3m tons of fish (usually dead or dying) are thought to be discarded each year from marine fisheries around the world. But these estimates come mostly from observations of large-scale industrial fisheries. Limited attention has been paid to small-scale fisheries, which are assumed to have low discard rates – some estimate as little as 3.7% total catch, compared to more than 60% for some large-scale shrimp trawlers.
Small-scale or artisanal fisheries – for which there is no universal definition – are generally considered more sustainable than their large-scale industrial counterparts, but there is increasing evidence that shows this is not always the case. They employ more than 99% of the world’s 51m fishers and likely account for more than half of the total global fisheries catches.

One of the biggest problems for both large and small-scale fisheries around the globe is bycatch – fish and other marine organisms caught when the fishers are targeting something else. Powerful images of turtles and dolphins caught in fishing gear have caught the sympathy of the general public, but unintentional landings of fish aren’t as evocative. The truth is, however, that fish bycatch is a big issue.
Progress is being made in Europe within large-scale fisheries thanks to campaigns such as the Fish Fight. But small-scale fisheries – though there is increasing recognition outside that they are “too big to ignore” – are only just beginning to recognise the fish bycatch and discard problem.
Catch and bycatch.
Our newly published research has found that artisanal fisheries in Sri Lanka are throwing away more marine species than they keep. For every fishing trip in one of Sri Lanka’s largest lagoons, Puttalam Lagoon, fishermen could be throwing away more than 50 fish. What’s more, of the 62 species recorded in the survey, more than 80% were routinely discarded. The reasons for this practice are unclear but sometimes it is because the individual fish are too small – or they are species without a high market value.
We found that fishers targeting shrimp in particular caught more non-target species and had higher discards than those targeting fish. This is particularly worrying at a time when Sri Lankan shrimp exports are increasing, after the EU granted the country improved access to its market.
Fishers in Puttalam Lagoon discard non-target catch onshore.
Potentially 90% of the world’s fish stocks are threatened by over-fishing – when more fish are caught than the population can replace. And the “tell-tale” signs of over-fishing are now being observed in Sri Lanka and across other research sites in the Indo-Pacific region. Fishers in these locations have told us and other researchers that they are catching much less fish than they were five years ago.
But this is not just an ecological issue, it is a social one too. In this era of increasing food insecurity, our findings highlight a serious concern for Sri Lanka. This unwanted seafood could be used to provide protein for the poorest in society. Instead, we found that fish with high nutritional value is being eaten by feral dogs and birds.
Unwanted fish end up as quick and easy meals for animals.
Billions of people worldwide rely daily on fish for protein, while 50m people also rely on catching fish for work. But, if the levels of bycatch and discard continue, the livelihoods and food security of the people that depend on these fisheries will be under threat. If the problem is not managed, there won’t be any fish left in the waters.
There is one ray of hope for Sri Lanka, however. There are some small-scale fishery cooperatives which maximise long-term community benefits by dealing with the threats of fisheries mismanagement, livelihood insecurity and poverty. Communities with successful and inclusive cooperatives are better off than those without. Cooperatives have the potential to empower small-scale fishers against environmental and socioeconomic shocks, but the problem in Puttalam Lagoon is that these cooperatives are not operating across all levels of society.
Fishing cooperatives do exist, but there could be more.
If the bycatch and discards issue is going to be solved over the long-term, we need to look at combining sustainable management practices with community schemes to reduce unnecessary seafood waste all over the world. Together the millions of small-scale fishers all over the world have an immense amount of power, they just need to realise it.

Britain’s seagrass is a refuge for numerous species of fish, stabilises sandy beaches, and helps to lock away the carbon which humans produce. The meadows that surround the country’s coast have been called the “canaries of the sea”, due to their sensitivity to a changing environment. And like a canary in a coal mine, their health can be used as an indicator of the condition of coastal areas.
We know that the seagrass meadows surrounding the UK are in a perilous state of decline, and our recently published research has now uncovered one of the biggest causes. Our study suggests that a major driver of seagrass decline is nutrient pollution from sewage and livestock waste.
Though a new finding, it sadly comes as no surprise, given that about 40% of rivers in England and Wales are polluted with sewage.
This nutrient pollution puts the long term viability of seagrass meadows in doubt. Over-enrichment results in the suffocation of seagrass. The nutrients cause microscopic algae – called epiphytes – to smother the seagrass leaves, decreasing their ability to capture light, ultimately killing them, and destroying the habitat for fish and other marine animals.
The seagrass, Zostera marina, covered in epiphytes.
In addition to this environmental impact, we found that several areas, including the Thames waterway seagrass, and a meadow in Studland Bay, Dorset – which are popular with swimmers and boaters – were considerably enriched in nutrients from sewage, livestock effluent and/or human waste. Despite this, neither location, nor any other we identified with the same problem, were classed as unsuitable for swimmers.
Clearly, we have a massive problem at hand – but water companies, farmers and the government have not done and are still not doing enough to prevent it.
Though efforts have been made to develop a British marine protected area network, and EU legislation has improved water quality in the last few decades, we have found these initiatives to be insufficient. Ten of the 11 sites we studied were in areas with designated EU protection, but most of these seagrass meadows were still polluted with nutrients derived from urban sewage and livestock waste.
So how has this happened? Analysis of the seagrass tissues points to constant sewage exposure. Old and outdated water treatment facilities are one of the likely culprits, resulting in discharges of untreated sewage during times of heavy rainfall. These are legal, but evidently the capacity of these facilities is insufficient to handle the country’s needs, and waterways are suffering because of it.
There is also the problem of livestock waste. Farming is now one of the UK’s leading causes of water pollution, and inefficiencies in storage and disposal of slurry mean that it ends up in rivers and coastal waters.
Evidently, in addition to national and international initiatives, we need to start quickly identifying and understanding all local threats to seagrass. Especially if we are going to harmonise conservation goals with sustainable economic development. Only by finding out specifically where the nutrients affecting seagrass areas have come from can we really start to think about a targeted solution for each meadow.
Unfortunately, to date, the conservation of specific seagrass meadows is rarely based on the explicit consideration of local threats and drivers. Instead, projects focus on conserving seagrass as part of a broader plan, incorporating other specific habitats or species. While this may be effective at dealing with problems such as fisheries impacts, and is certainly a step forward for the marine environment, it doesn’t deal with the persistent and chronic problem of pollution – which can go largely unnoticed.
Poor water quality isn’t just a problem for seagrass in the British Isles, it’s a global concern. But if we want to solve it, we must look beyond “protecting” seagrasses with legislation, and challenge the way we think about marine protection overall. Serious infrastructure changes and better management of river catchments – for example, restoration of riverbanks – are vital if we are going to develop long term waste water management plans that span both land and sea.

Hello Team Seagrass!
I am Rufus, a volunteer with Project Seagrass and a marine biology graduate from the University of St Andrews. Since graduating in June 2017, I have begun working for the Scottish Chamber Orchestra's Connect team and the University of St Andrews' Music Centre. In this split position, I get to enjoy the benefits of working with extraordinary artists and musicians across the country to inspire babies, toddlers, children, students and adults to get more involved with the music in the community around them.
There are so many educational opportunities provided by both the Scottish Chamber Orchestra and the University of St Andrews. Through its Connect programme, the Scottish Chamber Orchestra interacts with over 10,000 people each year through a vast array of activities. Both the staff and the musicians of the orchestra are extremely driven to reach new audiences all the time, not only to encourage interaction with music in the future but also, in some cases, to improve quality of life.

The Music Centre at the University St Andrews has also led some fantastic workshops throughout local schools in Fife with some of the excellent artists that come to the town to perform. One of the University's initiatives that I have been involved in is Music Planet. This is a platform that promotes the combination of the arts with global environmental issues to enhance the power of the message that is conveyed, and also to engage new audiences.
Music is a fundamental part of human culture, irrespective of where you come from or what your background is. There aren't many people who don't enjoy listening to some form of music, either when they are travelling, working, cooking, cleaning or as any other part of their day. I believe that because of this, music has the most potential in interdisciplinary education. Using music, and getting an audience to be involved with music and music making, will help to engage them with any subject.

One of the easiest combinations that can be made is music and nature because, in nature, music is all around anyway. The natural soundscape has endless capabilities that can be tapped into to expand the possibilities of what you are teaching. In March, I will be co-leading a SCO workshop, with SCO violin Aisling O'Dea, for primary schools in Fife in conjunction with Project Seagrass and Music Planet from the University of St Andrews. A team of musicians from the orchestra and volunteers from Project Seagrass will provide a day workshop for pupils at primary schools centered around the children's story, "The Snail and the Whale" by Julia Donaldson. This excellent book tells the story of a snail that seeks to see the world and journeys across the oceans on the tail of a humpback whale. In the end, it is an endearing story of community and self-worth.

The day will be centered around this story's characters and the music that was written to accompany the story. Various activities throughout the day will involve the children in the scientific background behind important environmental issues whilst providing them the opportunity to get involved with the music making themselves.
At this important tipping point, the future of the planet as we know it relies on the engagement of the public all over the world. Music can help to broaden the prospects of domestic and international education campaigns to make that change.
If you would like to follow more of my activity, I have recently started a personal challenge and campaign to reduce my impact on the environment - #Green18. In my attempt to complete this challenge, I will write regular blog posts to document my success and any obstacles I have encountered along the way.

Happy New Year Team Seagrass!
I can’t believe it’s 2018 already, and I’m sure that is a sentiment we all share!
2017 was an unbelievable year for all kinds of reasons, yet despite the crazy world we now seem to live in, for a few of us it has been largely a case of business as usual, and for the four of us as Project Seagrass, that consistency has been only been a good thing!
Now I’m not going to spend this New Year’s blog recapping on what we got up to in 2017, I’ll just point you to our previous ‘4th Year’ blog post and save the rest for future reminiscing this summer, as we celebrate the BIG ‘5th Year’ as an NGO.
We are certainly looking forward to this July!
In 2018 we have BIG aspirations, we hope to release a GLOBAL version of our SeagrassSpotter application which will make it possible to record your seagrass sightings anywhere on this precious Blue Planet.
Blue Planet. Green Seas. In 2018, we are taking Seagrass Spotter to the world.
Since its initial launch in late 2015, we’ve been tinkering with the SeagrassSpotter app, expanding its sphere of use from just our local waters, to now encompass the North Atlantic Ocean, Caribbean Sea and Mediterranean Sea. With help from various end users, we've co-created a new version of the application that brings in elements that we, as scientists, had overlooked. Over the last 12 months the real challenge has been in developing the app for the regions around the Coral Triangle with its exceptional levels of biodiversity!
In 2018, we are also looking forward to the 13th International Seagrass Biology Workshop in Singapore. The International Seagrass Biology Workshops are official World Seagrass Association events. World Seagrass Association members facilitate the organisation of these biennial meetings and the World Seagrass Association usually provides some financial support where possible. The International Seagrass Biology Workshop series have taken place around the world since Japan in 1993 (when I was just 9 years old!) and have evolved out of recognition of the global focus of seagrass issues.
Just from looking at the locations of previous meetings it is clear that these workshops are truly international events!
ISBW12: Nant Gwrtheyrn, Wales. 17 - 23 October 2016.
ISBW11: Sanya, China. 7 - 10 November 2014.
ISBW10: Rio de Janeiro, Brazil. 25 - 30 November 2012.
ISBW9: Phuket–Trang, Thailand. 21 - 30 November 2010.
ISBW8: Bamfield, Canada. 31 August - 5 September 2008.
ISBW7: Zanzibar, Tanzania. 10 - 16 September 2006.
ISBW6: Townsville, Australia. 24 September - 1 October 2004.
ISBW5: Ensenada, México. 7–11 October 2002.
ISBW4: Corsica, France. 25 September - 1 October 2000.
ISBW3: Pangasinan, Philippines. 19 - 26 April 1998.
ISBW2: Rottnest Island, Australia. 25 - 29 January 1996.
ISBW1: Kominato, Japan. 24 - 26 August, 1993
Of course, the other big global event for Team Seagrass in 2018 is The 5th International Marine Conservation Congress in Kuching, Sarawak. Which is being held this summer between the 24th - 29th June. As a gentle reminder, the Call For Abstracts for this OPENS ON THE 5TH JANUARY 2018 (i.e. tomorrow!) so get submitting!
We hope we will be able to catch up with many of our colleagues at these events this year and we are always on the lookout for collaborations which will help catalyse positive change for our oceans. We've got a few innovative collaborations already pipelined (which I can't reveal at this point!) but we will do as soon as they are all confirmed! So please get in touch with your ideas at [email protected]
Despite all the adversity of the past 12 months I feel genuinely optimistic that this year will be a BIG ONE on the journey to put our “Green Seas” on the map.
So keep up that Ocean Optimism, galvanise yourself for the year ahead, and remember what we are fighting for…
In the words of David Attenborough;
“It's our green seas, not the blue, that bring life to our oceans.”
Happy New Year!
