IPM Group Boosts Research on Invasive Species in Port Environments

The project involves the installation of tiles submerged at an approximate depth of three meters, attached to bollards or other static points in the harbor, using ropes.

This simple system acts as an artificial substrate, facilitating the attachment of marine organisms and allowing for subsequent analysis of biological colonization in port environments.

In this study, the main objective is to assess the presence and degree of invasion of Branchiomma, a tropical marine worm that has been recorded as an invasive species in the Mediterranean.

Due to its numerous reproductive strategies, Branchiomma has a high capacity for dispersion and colonization in new areas, establishing itself in port environments and other coastal habitats.

Sergi Guasch, a student in the Master's program in Marine Ecology at the Universitat de les Illes Balears (UIB), explained, "The goal of the project is to evaluate the degree of invasion of this genus in different ports of the Balearic Islands using a simple and minimally impactful methodology. For this purpose, small submerged tiles are installed, fixed to bollards or other structural points in the harbor, for an approximate period of three months. These structures act as new substrates, allowing the attachment of Branchiomma and facilitating the analysis of its presence and abundance. It is a totally passive method that does not alter the environment or interfere with port activities. The study aims to provide key information to improve the knowledge and management of invasive species in port environments."

In addition to the participation of Sergi Guasch, the initiative has also involved collaboration from Ana González, from the Environmental Technical Assistance of the Balearic Port Authority (APB), who has contributed to the supervision and development of the initiative.

From a technical viewpoint, this type of study provides relevant data on the adaptability of invasive species in new environments, their impact on native biodiversity, and possible mitigation strategies.

Moreover, it provides key information for the implementation of environmental management plans in port areas, helping administrations and companies to make decisions based on scientific evidence.
