“…According to feeding experiments, in which no negative effects were detected [ 77 ], a total absence of oxylipins was found in C. scutellum [ 22 ]. This result supports those by Zupo et al [ 81 ] that post-larval feeding with C. scutellum induces only positive effects such as post-larvae settlement (about 63%) and survival.…”

The chemical ecology of marine diatoms has been the subject of several studies in the last decades, due to the discovery of oxylipins with multiple simultaneous functions including roles in chemical defence (antipredator, allelopathic and antibacterial compounds) and/or cell-to-cell signalling. Diatoms represent a fundamental compartment of marine ecosystems because they contribute to about 45% of global primary production even if they represent only 1% of the Earth’s photosynthetic biomass. The discovery that they produce several toxic metabolites deriving from the oxidation of polyunsaturated fatty acids, known as oxylipins, has changed our perspectives about secondary metabolites shaping plant–plant and plant–animal interactions in the oceans. More recently, their possible biotechnological potential has been evaluated, with promising results on their potential as anticancer compounds. Here, we focus on some recent findings in this field obtained in the last decade, investigating the role of diatom oxylipins in cell-to-cell communication and their negative impact on marine biota. Moreover, we also explore and discuss the possible biotechnological applications of diatom oxylipins.

“…The higher metamorphosis rates obtained when algae were in contact with larvae could also be linked to the presence of microbial biofilms on the algae surface (Dworjanyn and Pirozzi 2008;Orvain et al 2015). Indeed, natural biofilms are also widely used in P. lividus metamorphosis induction (Gosselin and Jangoux 1996;Liu et al 2007;De la Uz et al 2013;Brundu et al 2016) as well as diatom-based biofilms (Rial et al 2018;Zupo et al 2018). Further research could also be done in this way.…”

“…In the last years, several microalgae species have been tested in order to optimize the larvae culture, such as the genus Isochrisis, Dunaliella, Rhodomonas, Chaetoceros, Tetraselmis and Nannochloropis (Ahmed, Elmasry, El-Sayed, & Razek, 2016;Carboni, Vignier, Chinatore, Tocher, & Migaud, 2012;Castilla-Gavilán, Buzin, et al (2018a); Castilla-Gavilan, Turpin, Buzin, Cognie, and Decottignies (2018b)). Some benthic diatoms such as Cocconeis, Diploneis, Navicula, Cylindrotheca and Nanofrustulum were also tested in order to improve settlement success (Zupo, Glaviano, Caramiello, & Mutalipassi, 2018).…”

The quality of the microalgae provided on Paracentrotus lividus larvae rearing is a primordial factor having a direct (nutritional properties) and indirect (water quality) impact on growth, competence and survival. Skeletonema costatum is a diatom commonly used in the bivalve cultivation. However, the use of this diatom in P. lividus larval cultivations is poorly known. The Rhodomonas spp. is a microalgae commonly used in sea urchin larvae culture. Three different diets were tested on P. lividus larvae and post-larvae cultivation (D1-Rhodomonas marina, D2-S. costatum, D3-mixture of both algae). Larvae fed with the D2 diet (55.8%) and D3 (39.9%) had a survival at 15 DAH higher than D1 (5.5%). The low survival in D1 could be due to the higher microbiological load on microalgae (Vibrio alginolyticus and V. pectenicide). Larvae fed with S. costatum (D2) showed a lower development than other diets. The competency index was lower for larvae fed with the D2.These results show that microalgae diversified diets contribute to a better development of P. lividus larvae. During the settlement and post-settlement phase, there was also a lower growth of the sea urchin fed with the D2 and a higher survival for D3.
