The Lagocephalus invasion


Lagocephalus sceleratus
is the worst invasive species in the Mediterranean Sea with a significant impact on the surrounding ecosystem and on the fisheries sector (Zenetos et al., 2005; Peristeraki 2006; Streftaris & Zenetos 2006; Ozturk 2010). More importantly, L. sceleratus is considered to be a serious hazard to consumers since it contains a strong marine toxin called tetrodotoxin (TTX), which can be lethal to humans. In addition, L. sceleratus has been recorded to destroy fishing nets and lines leading to economic losses for fishers. The purpose of this project is to study the relative abundance distribution of Lagocephalus sceleratus in Aegean Sea with a focus on the potential commercial use of this species. If left unchecked this species will result in serious environmental and economic damage to Mediterranean’s already degraded fisheries.

Programme Objectives
Video and photographic documentation of the presence of L. sceleratus
in the waters of the islands of Aegean Sea.
Through the Internet, local media, Coast guard inform the public and fishermen about the dangers of this toxic fish, not edible. In collaboration with Greek Authority spreading of guidelines and protocol for first aid in case of ingestion of this fish.
Creation of an internet data bank and map through sightings, pictures and gps position helping also by supporters and all those people will follow the project.

Goals and Benefits
The benefits of being involved with the L. sceleratus
programme include:
Educate fishermen on this invasive alien species.
 A greater understanding of our fisheries
 Training on safe handling of the L. sceleratus
Prevention of accidental injury, poisoned from the ingestion.
 The conservation, preservation and protection of Mediterranean’s ecosystem.

: OCEANUS onlus

is a neurotoxin that occurs in select species of the family Tetraodontidae (pufferfish or fugu). It is an amino hydroxy quinazoline compound. In marine pufferfish species, toxicity is generally high in the liver and ovary, whereas in freshwater species, toxicity is higher in the skin. TTX is produced primarily by marine bacteria, and pufferfish accumulate TTX via the food chain that begins with these bacteria. It is one of the most potent, nonprotein poisons known to man.
