Poole Harbour oil spill could have serious consequences for threatened migratory fish, say GWCT experts
[ad_1]

UK wide conservation organisation the Game & Wildlife Conservation Trust (GWCT), has today highlighted it’s serious concerns over the impact of the 200-barrel fluid leak into Poole Harbour on protected migratory fish. The GWCT operates the Salmon & Trout Research Centre on the River Frome at East Stoke, Dorset which has been monitoring the salmon population in depth for 50 years.
A major incident was declared on Sunday 26 March 2023, when a leak occurred at a pipeline operated by gas company Perenco.
The leak coincides with the start of the sea-bound migration of vulnerable young Atlantic salmon (Salmo salar) and sea trout (Salmo trutta), known as smolts, from the Rivers Frome and Piddle which flow directly through Poole Harbour. The young salmon and trout hatch from eggs laid by adults in the river, where they spend between 1 – 3 years before migrating to sea from March to mid-May. Here they will feed and grow for a further 1 – 3 years before returning to the river of their birth to reproduce.
Every Spring GWCT scientists trap smolts to quantify how many are leaving the river and to scan them for a PIT-tag (a microchip which enables them to identify individuals) and record biometric information, before releasing them.
“This is the worst possible time for migratory salmonids. We are currently catching them in numbers through our smolt trap so we know that they are passing through Poole harbour at the moment,” said GWCT Head of Fisheries Research, Dr Rasmus Lauridsen.
Dylan Roberts Head of Fisheries at GWCT, which is a member of the Missing Salmon Alliance, said “During their migration through estuaries, they are at a crucial and highly sensitive stage of their life cycle as their bodies adjust to transferring from living in rivers to sea water. We are extremely concerned that these increasingly rare young fish, may perish in the polluted waters.”
When exposed to oil, adult fish may experience reduced growth, enlarged livers, changes in heart and respiration rates, fin erosion, and reproduction impairment. Fish eggs and larvae can be especially sensitive to lethal and sublethal impacts. Even when lethal impacts are not observed, oil can make fish and shellfish unsafe for humans to eat.[1]
The River Frome is recognised for its environmental importance. It is a designated Site of Special Scientific Interest (SSSI) for its ecology and geomorphology including salmon and sea trout, and a Special Protection Area (SPA) for Birds. Poole Harbour designated as a Site of Special Scientific Interest, a Special Protected Area and a Ramsar site.
Some areas of the British Isles have seen over a 70% decline in wild Atlantic salmon in the past 25 years. Most wild salmon populations in England’s rivers are below sustainable levels and classified as ‘At Risk’ by the Environment Agency which is tasked with their protection.
Atlantic salmon are listed as vulnerable on the European IUCN Red List of Threatened Species. It is also a species of international concern and is listed under the Bern convention, and listed to be protected under the Water Framework Directive. The Rivers Frome and Piddle, which flow into Poole Harbour, are home to other migratory species which migrate from rivers to the marine environment for part of their life cycle. These include the European Eel (Anguilla Anguilla) which is listed as critically endangered on the IUCN Red List, and the Sea lamprey (Petromyzon marinus), which are migrating through Poole Harbour at this time of year.
The River Frome is one of twelve Index Rivers for Atlantic salmon around the North Atlantic which are used to report the condition of wild salmon populations by the International Council for the Exploration of the Seas (ICES), and are used to set international exploitation rates for salmon fisheries across the Atlantic.

Scotland’s Rewilding Revolution: Ecological Benefits and Global Influence
Scotland’s rewilding initiatives are transforming landscapes and ecosystems, offering ecological benefits and inspiring global conservation efforts. Explore the impact and future prospects of this bold environmental strategy.
In the misty highlands of Scotland, a quiet revolution is taking place. Rewilding, a concept that aims to restore ecosystems to their natural state, has been gaining momentum, transforming vast areas into thriving habitats. This ambitious movement is not only reshaping the Scottish landscape but also providing significant ecological benefits that echo far beyond its borders.
Central to the rewilding efforts are projects like the Cairngorms Connect and Trees for Life, which focus on restoring native forests and reintroducing keystone species such as the Eurasian lynx and beavers. These initiatives aim to enhance biodiversity, improve ecosystem services, and combat climate change by sequestering carbon in regenerating woodlands.
The ecological benefits are manifold. By reintroducing native species, these projects help restore natural processes and food webs, leading to healthier and more resilient ecosystems. The return of beavers, for instance, has been transformative; their dam-building activities create wetlands that support a myriad of plant and animal species, increase water retention, and reduce flood risks.
Moreover, rewilding contributes to soil restoration and enhances carbon capture. As diverse plant communities establish themselves, they improve soil structure and fertility, which in turn supports a broader range of wildlife. This natural regeneration process not only bolsters biodiversity but also plays a critical role in mitigating climate change.
However, the journey is not without its challenges. Critics argue that rewilding can conflict with traditional land uses, such as farming and grouse shooting, which are economically important to local communities. Balancing these interests requires careful negotiation and collaboration between stakeholders to ensure that rewilding projects are both ecologically and socially sustainable.
Looking ahead, Scotland’s rewilding initiatives hold immense potential to inspire similar efforts globally. By demonstrating the ecological and economic viability of rewilding, Scotland could galvanize international conservation strategies and contribute to global biodiversity targets.
As these wild landscapes continue to evolve, they offer a glimpse into a future where humans and nature coexist in harmony, each thriving in a supportively interconnected world. Scotland’s rewilding efforts may well be the blueprint for ecological restoration worldwide, as nations grapple with the twin crises of biodiversity loss and climate change.
