Acuario instalado como base para plans de formación permanente do profesorado e que actualmente é a base de proxectos e traballos do Bacharelato de Excelencia Científica STEM BACH. Empezou no curso 2020. Está instalado no departamento de Bioloxía e Xeoloxía e Colabora o Departamento de Física e Química e Tecnoloxía. Iniciouse o proxecto baixo a tutela do CFR de Ourense e co apoio do Equipo Directivo.

Back to basics: Global shortage of bacteriological agarRicardo Melo
At present laboratory reagent companies are suspending supply of specialised agar products due to low availability of raw material. These bacteriological/technical agars used in laboratories around the world are predominantly obtained from species of a single red algal genus, Gelidium. Harvesting of natural populations is the only source of feedstock as cultivation has never been feasible. Here we analyse historical landings data since the 1920s in all countries where natural Gelidium resources have been harvested. Up to WWII Japan was the only source of agar but then other countries like Spain, Portugal, Morocco, Mexico, and South Africa began to survey and exploit local Gelidium resources. Gelidium landings peaked in the 1960’s, while Japan lost market dominance. A sustained decrease in landings to less than 50% of peak annual values has occurred since. This trend was accompanied by concentration of feedstock production in just one country, Morocco, which contributed over 70% of world supply in the last two decades. A sudden decline in this country’s landings will have a disproportionate effect on world availability of Gelidium. This is actually the present situation when landing and export quotas were recently implemented in Morocco in order to safeguard the natural resources. Thus Gelidium agar is now undersupplied and priced itself out of the food industry but the increasing demand of bacteriological and technical agars will probably create an opportunity for historical producers, where production has declined, to get back into the market. If an interest in Gelidium resource exploitation is renewed adequate scientific management practices should be implemented. For this, simple harvest statistics such as daily harvest yields and harvest effort need to be collected by harvest area. Estimates of both the standing stock and the exploitation rate of the resource can then be calculated, without the need for time and space extensive, high cost sampling assessments.

Social and ecological attributes of marine recreational fisheries in the Euro...Pablo Pita Orduna
Oral presentation at the 8 World Recreational Fishing Conference, Victoria, Canada.
There are growing concerns about the impact of Marine Recreational Fishing (MRF) on ecosystems and its combined effects with other human activities, such as commercial fishing, especially in the higher trophic levels. On the other hand, recreational fishers make a considerable economic contribution by their expenses in materials, boats, licenses and travel costs and accommodation. However, little research has been conducted on MRF in Europe, particularly in the South. In the Euroregion Galicia-Northern Portugal extensive research in basic features of MRF is still needed to support management decisions and to reduce growing conflicts between recreational and commercial fishers and other stakeholders. In this work we have analysed the social, economic and ecological impact of the MRF in this Euroregion by characterizing the types of users, estimating their costs and their catches by species. In particular, we have performed on-site and on-line interviews with fishers of the different mêtiers to gather economic information (costs, disbursements and profitability), social (education, occupation, age, residence, sex, generation of direct and indirect jobs and complementarity with commercial fishing and tourism) and ecological (trends and factors influencing abundances, gears used, species targeted and seasonal and daily effort and catches). Management recommendations have been given to improve socio-ecological sustainability of MRF.
A matter of scales. The management of marine recreational fisheries in the EUPablo Pita Orduna
Oral presentation at the 8 World Recreational Fishing Conference, Victoria, Canada.
There is growing recognition of the importance of inclusion human dimension in models for the assessment of stocks and the development of fisheries management measures. The sustainable management of these complex socio-ecological systems involves integrating different administrative levels or incorporating bottom-up management approaches. The objective of this paper is to present a critical review of the current management of Marine Recreational Fisheries (MRF) in Europe, in the context of increasing demand for marine ecosystem services that is leading to conflicts between groups of stakeholders. In particular, we analyzed how the European regulations on MRF support the Ecosystem Approach to Fisheries (EAF) in different geographic areas. The European Union (EU), national, and regional legislation were analyzed for four countries (Germany, Portugal, Spain and the UK) chosen to represent the full range of conditions across Europe. An Integrated Policy Legal Index (IPLI) for each of the countries was calculated from 57 criteria including biophysical attributes (geographical, ecological and biological aspects), social drivers across a range of stakeholders, and attributes of the governance systems. The IPLI was used to assess if the different legal frameworks follow the principles considered prerequisites for long-term, sustainable management of community-based common pool resources. Scale and institutional issues impacting on the management of MRF in Europe will be discussed including impacts on targets for ecological and socio-economic sustainability.
