During 2008, the bacterium Photobacterium damselae subsp. piscicida was identified in meagre (Argyrosomus regius) culture during three disease outbreaks which occurred in Tenerife, Canary Islands, with mortalities reaching 50%. Typical disease signs were observed, including the characteristic spleen nodules, and bacterial identity was confirmed by biochemical and serological tests. This is the first reported isolation of Photobacterium damselae subspecies piscicida associated with mortalities in meagre. See details: Costa, J.Z., U. McCarthy, O. Pérez, E. Ramos, M. Rodríguez, Ó. Monterroso & R. Riera (2017). Occurrence of Photobacterium damselae subsp. piscicida in sea-cage farmed meagre (Argyrosomus regius) in Tenerife, Canary Islands, Spain. Thalassas.

The hydrozoan Macrorhynchia philippina is considered a circumtropical and subtropical species. In the last years, its distribution has been spread at higher latitudes because of global warming, facilitated by its invasive character. Macrorhynchia philippina develops prominent colonies that have the potential to colonize rapidly new substrates, showing invasive potential. See details Riera, R., F. Espino & L. Moro. 2016. Progressing the invasion of the hydrozoan Macrorhynchia philippina (Kirchenpauer, 1872) in Atlantic archipelagos. Vieraea, 44: 117-120.

The common octopus (Octopus vulgaris, Cuvier 1797) is a promising species for aquaculture diversification, but the massive mortality during the first life stage is the main bottleneck for its commercial production. A total of 26 independent assays were used, including data from the bibliography and from experiments carried out by our group. Three comparisons were established: (i) crustacean zoeae vs Artemia, (ii) different crustacean zoeae species and (iii) Artemia enriched with marine lecithin (rich in polar lipids-PL and docosahexaenoic acid-DHA) vs previously used Artemia enrichments. The meta-analysis approach allowed a quantitatively review of independent studies with reliable conclusions, avoiding the subjectivity inherent to classical reviews. Check out!!. Garrido, D., V.M.
