Morphological vs. molecular identification of trematode species infecting the e...
Stout, Leslie; Daffe, Guillemine; Chambouvet, Aurélie; Correia, Simão; Culloty, Sarah; Freitas, Rosa; Iglesias, David; Jensen, K. ThomasIdentifying marine trematode parasites in host tissue can be complicated when there is limited morphological differentiation between species infecting the same host species. This poses a challenge for regular surveys of the parasite communities in species of socio-economic and ecological importance. Our study focused on identifying digenean trematode species infecting the marine bivalve Cerastoderma edule acros...
Comparative study on cellular and molecular responses in oyster sperm revealed ...
F RIESCO, MARTA; Félix, Francisca; Matias, Domitilia; Joaquim, Sandra; Suquet, Marc; Cabrita, ElsaThe Portuguese (Crassostrea angulata) and Pacific oyster (Crassostrea gigas), both from the genus Crassostrea, are two important species for production and conservation. Although they have common characteristics, different susceptibilities to rearing conditions have been described in these species. Overall, in the case of C. angulata, only a few remaining populations are present in the south of Portugal and Spa...
First study in cryopreserved Crassostrea angulata sperm
F RIESCO, MARTA; Félix, Francisca; Matias, Domitilia; Joaquim, Sandra; Suquet, Marc; Cabrita, ElsaSperm cryopreservation is a widely employed technique that promotes alternative techniques to contribute to broodstock management or restoration programs for species of commercial interest, endangered species or species with an interesting genotype. The preservation of genetic material from improved stocks or from the original population is extremely important for the oyster aquaculture industry to prevent the ...
New species in aquaculture: are the striped venus clam Chamelea gallina (Linnae...
Joaquim, Sandra; Matias, Domitilia; Matias, Ana Margarete; Gonçalves, Rui; Chicharo, Luis; Gaspar, MiguelThe surf Spisula solida and the striped venus Chamelea gallina clams support important fisheries in Europe. These fisheries have been affected by inter-annual fluctuations in stock abundance and recruitment failures. Aquaculture could contribute to address these problems through the production of larvae or juveniles for stock-enhancement programmes. In the present study, the prerequisites to produce these speci...
Rebuilding viable spawner patches of the overfished Spisula solida (Mollusca : ...
Joaquim, Sandra; Gaspar, Miguel; Matias, Domitilia; Ben-Hamadou, Radhouan; Arnold, William S.Populations of commercially important bivalves along the coast of Portugal are depleted as a consequence of natural and anthropogenic causes. A pilot experiment was designed to determine the feasibility of transplanting individuals from natural clam beds to a closed fishing area in an effort to rebuild relatively high-density patches of Spisula solida. For this purpose, clams were equally partitioned into two g...
