The project aims to deepen the knowledge of reproductive biology and hatchery production of various species of bivalves to implement restocking programs and improve productivity of the aquaculture sector. Knowledge of reproductive strategy of the species will allow to answer to the requires of the expanding bivalve hatcheries in Portugal, contributing with more information on the optimization of production protocols, through the assessment of nutritional needs, making profitable and revitalizing the production and commercialization of species with market potential.
The assessment of the environmental factors effects and their changes on fertilization and larval viability provides insight into the influence of climate change on the recruitment of commercially important bivalve species. The knowledge of environmental phenomena consequences on aquaculture will allow for more sustainable resource management measures, including restocking with hatchery produced specimens, to mitigate adverse effects.
Restocking with hatchery produced larvae / juveniles can be an asset to the fishing industry and to address fluctuations that occur in Algarve coast in certain years. Similarly, the introduction of new species into aquaculture, particularly from other invertebrate groups, can be of great relevance both in terms of resource recovery and in the introduction of new consumer-friendly products or obtaining other products.
The techniques used for European clam hatchery production cannot yet provide an established protocol that allows the continued production of juveniles throughout all year, so it is necessary to invest in their improvement. This project aims to test new sustainable production methods that will improve the production protocols of this species without neglecting animal welfare.
Oyster and European clam production in Algarve lagoon systems is based on rudimentary techniques, often using materials that have both a negative environmental and visual impact. It is therefore urgent to find alternative oyster production systems more eco-friendly in order to reduce the impact of this activity on environment. On the other hand, the oyster production in Ria Formosa has been increasing significantly, reaching a density that is a concern for producers. It is therefore important to know the load limits of co-production of these species in this lagoon system. This project aims to generate knowledge that will contribute to improve the production processes of these species, including the energy needs of individuals.
The project also intends to promote the exchange of experiences and good practices between IPMA and professionals; develop training and dissemination actions for aquaculture producers, administration and the scientific community.
