A case involving 25 protected sea urchins allegedly harvested from Maltese waters in Marsaskala has brought renewed attention to the recovery of one of Malta's depleted coastal species.
The Environment and Resources Authority says Malta Police and ERA enforcement officers apprehended a person on 30 August 2026 who had allegedly collected 25 protected sea urchins. The animals had already died and could not be returned to the sea. ERA says the case will be brought before the Court.
Why collection remains prohibited
Malta introduced a moratorium on collecting the stony or purple sea urchin, Paracentrotus lividus, in 2023 after research recorded very low abundance in Maltese coastal waters.
The prohibition has since been extended until 7 July 2027. Monitoring at 10 sites found increases in sea-urchin numbers at about 60% of the surveyed locations, while recovery at other sites remained weaker.
This does not mean Malta's entire population increased by 60%. It means improvement was detected at roughly six out of every 10 monitored locations, illustrating how uneven recovery can be.
Recovery takes time
Government monitoring found particularly encouraging numbers among smaller specimens measuring between two and four centimetres. Because sea urchins grow slowly, rebuilding depleted populations is a long-term process.
Sea urchins are grazing animals and form part of the ecological balance of Mediterranean rocky coastal habitats. Removing large numbers from already depleted areas can therefore affect more than the animals being collected.
Protection still depends on enforcement
The moratorium prohibits the collection, transport, sale and distribution of wild sea urchins from Maltese waters. Imported sea urchins may still be sold, but businesses must retain documentation demonstrating their origin.
The Marsaskala case shows why enforcement remains important even when monitoring begins to show signs of recovery. Slow-growing populations can lose hard-won gains quickly if illegal harvesting continues.
Suspected environmental illegality can be reported to ERA on 2292 3500.
