Halt the March of the Sea Urchin
Marine ecosystems on Tasmania’s east coast are under threat from the Centrostephanus sea urchin. Over-fishing of its key predator, the large Rock Lobster, and increasingly warmer waters caused by climate change have allowed this species to proliferate and spread further south.
If left uncontrolled Centrostephanus will remove all of the kelp from a rocky reef. It does not come back and the impact may be permanent. This destroys the habitat of juvenile Rock Lobsters and Abalone and virtually all other native species.
We are at risk of losing 32% of Tasmania's coastal reefs in the next four years unless we can stop the march of centrostephanus.
This would be a massive blow to Tasmania's Marine Biodiversity and economy. The Rock Lobster, Abalone and fishing industries all depend on this habitat for the continued survival of their businesses.
It's not to late to act, help us protect Tasmania's Oceans!
Rock lobster crisis
Destroying rocky reef habitats is causing a crisis for the rock lobster fishery as well as being an environmental disaster. The Rock Lobster fishery is the most valuable of Tasmania’s wild fisheries and it is a species highly prized by many Tasmanian recreational fishers. But across most of Tasmania’s east coast it has become virtually impossible to catch. Biomass levels are now down to less than 10% of their original numbers, meaning that fishery and species is on the verge of collapse.
With your help we can stop the spread of the sea urchin and prevent further decline in rocky reef habitat. We can ensure Rock Lobster exist for future generations.
Better management of Tasmania's fish farms
Tasmania has a large number of inshore fish farms that produce Atlantic Salmon and Ocean Trout. Faecal waste drifts out of the fish farms, along with excess nutrient feed. This causes a range of issues including de-oxygenation of the water and local environmental pollution. This pollutes areas of Tasmania's coastline, damaging valuable habitat and introducing disease into native fish stocks.
Stop the seal slaughter
Fish farm pens attract seals, Fish farmers can acquire permits to kill these seals. We are calling for an immediate ban on killing and relocating seals, and for farmers to install seal exclusion devices.
Impacts on recreational fishing and boating
Fish farms currently occupy waterways that are prime locations for recreational fishing and boating. The farms impact Tasmania's naturally beautiful waterways, that are an important part of local communities and tourist experiences.
