On 12 June Dr. Lluís Sala Genoher, member of the Costa Brava Water Consortium, gave a lecture titled “New trends and challenges of water reuse. The case of Costa Brava” at the Aula Magna of the University of Girona’s Faculty of Science. The event, organized by the research group LEQUIA and International Excellence Campus e-MTA had over 60 attendees from the academic environment of the University of Girona as well as several companies and entities related with water management and treatment.  Ampliar +

The thesis of Montserrat Josep Coll assesses the validity of tools for fishery management in the Balearic coast

Información actualizada el 11 June 2013

The thesis of Montserrat Josep Coll, defended at the University of the Balearic Islands, has assessed the validity of tools for fishery management in the Balearic coast. The work Evaluation of artificial reefs and marine reserves as tools for managing ichthyological coastal resources in the Balearic Islands was directed by Dr. Antonio Garcia Rubio, Center for Advanced Studies of Blanes.

The research has focused on the use of artificial reefs to enhance small commercial-scale fishing, and has shown that artificial reefs have generated a community of fish which is rich and comparable to that in natural seabed. However, the effect of artificial reefs on fishery is low. The total volume of artificial reefs did not exceed 600 m3 in any case, a low figure that is unlikely to significantly increase fish biomass compared to that found on natural seabed. Ampliar +

 

IMEDEA (CSIC-UIB) researchers warn about the negative impact of anchorages on fan mussel populations

Anchoring of recreational boats affects the conservation of the endangered largest species of bivalve mollusk in the Mediterranean

 A team of researchers at the Mediterranean Institute for Advanced Studies (IMEDEA, CSIC-UIB) has recently published a paper in the scientific journal Biological Conservation. This work highlights that the pressure from anchoring in waters of Mallorca and Cabrera has a negative impact on fan mussel. This species is the largest mollusk in the Mediterranean and is currently threatened.

 The fan mussel, also known as noble pen shell, (Pinna nobilis) is a bivalve mollusk  – that is, it has two shells -. This mollusk is endemic in the Mediterranean. It may reach up to one meter long and lives in posidonia seagrass meadows. At present, the decline in coastal habitats of seagrass due to the pressure of human activity has endangered the species.

The study assessed the population density of fan mussel in six different coastal locations placed in shallow water (between 5 and 6 meter deep) in Majorca and Cabrera. The goal was to identify the factors that may interfere with the presence of this endangered species.

The researchers have obtained a reliable estimate of the fan mussel populations in the six evaluated areas, and found quite different population densities, ranging from 1.4 to 10 individuals per 100 square meters. According to the IMEDEA (CSIC-UIB) researchers, these differences cannot be explained by factors related to habitat, such as bundle density and coverage of seagrass meadows, or by eviction caused by storms (which was evaluated by the maximum wind speed at each location).

However, the study noted that the density of fan mussel relates to the anchoring of recreational boats. The analysis of data obtained in this research has determined that in places where anchoring is banned the average density was 7.9 individuals per 100 square meters, while in places where boats could anchor density was reduced to an average of only 1.7 individuals per 100 square meters.

From this study, the researchers at IMEDEA (CSIC-UIB) highlight the importance of reducing the pressure of anchoring in seagrass meadows as a measure to promote the conservation of fan mussel, a protected and endangered species. Thus, they proposed the installation of permanent mooring buoys to reduce the impact of boats on seagrass meadows and, consequently, on fan mussel.
