The Aquaculture Research Group is part of the Centre of Marine Sciences (CCMAR), a non-profit organization located on the Gambelas campus of the University of Algarve and dedicated to R&D in the Marine Sciences. On the basis of international evaluation and excellence ranking CCMAR was awarded the status of Associate Laboratory together with CIIMAR (Interdisciplinary Centre for Marine and Environmental Research). It has 205 people on its staff, 88 and 114 of which hold a PhD and college degree, respectively.
The centre counts with laboratories and fish facilities for larval, juvenile and broodstock.
The aim of the Aquaculture Research Group is the generation of scientific knowledge, through basic and applied research, for the promotion of the sustainable development of the aquaculture industry. The group is comprised by 10 researchers with a PhD degree, in addition to a fluctuating number of guest researchers and students.
The group has expertise in several marine and fresh water fish species (gilthead sea bream, European sea bass, trout, dusky grouper, Senegalese sole and meagre).
Senegalese sole Epinephelus marginatus Sparus aurata
The main skills of the group include fish gametes quality evaluation and cryopreservation; phyto- and zooplankton production; tracer studies for study of nutrient utilization; larval rearing, feeding and nutrition of several marine fish species. These activities have been developed in the framework of several research projects over the last ten years, at both national and international level (e.g., PRAXIS XII, POCTI, INTERREG, STRIDE, AIR, FAIR, CRAFT and QLM programs).
The group also has a long collaboration on joint supervision of PhD theses with European institutions, participation in European research networks (COST, EATIP) and as partner in projects involving an industrial collaboration.

The group of Molecular Biology of Marine Organisms (EDGE) belongs to the Centre of Marine Sciences (CCMAR), located at the Campus de Gambelas of the University of Algarve in Faro, Portugal. Our group consists of 1 full Professor, 2 associated Researchers, 3 post-docs, 12 PhD students and several technicians, MSc students and undergraduate students. Most of the lab members are working in different aspects of skeletal biology of vertebrates and on the gene expression and regulation, either using model animals (zebrafish, marine teleosts, mouse and rat) or in vitro tools like the fish derived osteo-chondroblastic cell lines or the blastema and embryonic stem-like cell cells developed in our laboratory. Different lines of research are currently being followed by researchers in EDGE group, supported also by an excellent collaborative network involving companies and researchers from several institutions belonging to countries in Europe (11), Americas (3), Oceania (1) and Asia (1).
Main lines of research
Molecular determinants of extracellular matrix calcification. Research focus is primarily on understanding molecular pathways of tissue mineralization and its regulation in adult life and during development, using teleost, cartilaginous fish and amphibians as model organisms; additional goals include studies on (1) the molecular adaptations of mechanisms that control extracellular matrix mineralization, (2) the evolution of mineralization-related gene structure and protein function and (3) the mechanisms of mineralization in mollusc bivalves. Goals include (1) the use of integrated multidisciplinary approaches for in vivo / in vitro functional analysis of bone- and cartilage-related genes through techniques of overexpression and RNA interference, cell line and transgenic zebrafish development, (2) evolutionary studies on specific gene function and environmental adaptations affecting bone biology and (3) function of mineralization-related proteins from mollusc bivalves.
Zebrafish development and nutrition. Research is focused on the effects of nutritional factors on the mechanisms regulating zebrafish development, reproduction, osteogenesis and osteotoxicity. The main goal is to establish nutritional requirements at different life stages in order to develop a standardized diet for zebrafish and to test different micronutrients and molecules in order to maximize reproductive success and improve gamete quality, larval survival, early development and osteogenesis. An ongoing collaboration with the Aquagroup from the same research centre aims at developing novel strategies and procedures for zebrafish germ cell cryopreservation and development of molecular tools for sperm quality evaluation.
