“…muelleri (long setae), T. lutea and P. lutheri provided the best results registered in monoalgal experiment of this study (at least in growth and survival). Similar acceptance reports are found when those flagellates are included in the diet in experiments with Crassostrea gigas (Rico‐Villa et al., 2006; Wang, Li, Zhang, & Yu, 2018), C. virginica (Babinchak & Ukeles, 1979), Pecten maximus (Le Pennec & Rangel‐Dávalos, 1985), Argopecten ventricosus (Lora‐Vilchis & Maeda‐Martínez, 1997), Pteria sterna (Martínez‐Fernández et al., 2004), Ruditapes decussatus (Aranda‐Burgos et al., 2014), Placopecten magellanicus (Gouda, Kenchington, Hatcher, & Vercaemer, 2006), Pinctada margaritifera (Martínez‐Fernández, Acosta‐Salmón, & Southgate, 2006) and Ostrea edulis (González‐Araya & Robert, 2018).…”

Monoalgal and bialgal diet were tried in 2 stages of larval development of Striostrea prismatica: phase I from mixotrofic to early umbonated veliger larva and phase II until eyespot larvae. The monoalgal diets in phase I were Tisochrysis lutea, Pavlova lutheri and Nannochloropsis sp. In phase II, Tetraselmis suecica, T. chuii, Chaetoceros gracilis and Ch. muelleri were incorporated. The bialgal diets (combination of P. lutheri + Ch. gracilis in proportions 1:3, 1:1 and 3:1) were chosen according to the results of the monoalgal trials and were evaluated against the classic diet = control (T. lutea + Ch. gracilis). The microalgae size and their fatty acid composition were determined. We recommend the combination T. lutea + Ch. gracilis, initially using T. lutea for mixotrophic larvae (6 days Post Fertilization‐PF), then incorporating Ch. gracilis in a ratio of 1:1 until completing phase I (8–10 PF). In phase II, the ratio should change to 1:3 until larvae with eyespot are obtained (18–20 PF). Suggestions were based on the higher demand for DHA in initial larvae and the need for EPA from the early umbonated phase. Finally, as a third experiment, microsubstrates (pieces of shells, sandpaper, polycarbonate and ground rubber) were evaluated to promote the settlement of pediveliger larvae. A settlement of 20% was obtained in pieces of shells of the same species. We consider that the settlement technology has not been optimized; therefore, evaluations directed at the behaviour of the species are recommended.

“…lutea in proportions of 6.29%. Despite this, survival rates were relatively low, a condition contrary to that reported in other research related to high levels of DHA, for example, in the ostreids C. gigas(Rico-Villa et al, 2006;Wang et al, 2018), C. virginica(Babinchak & Ukeles, 1979) and O. edulis(González-Araya & Robert, 2018).…”

The rock oyster Striostrea prismatica (Gray, 1825) is a mollusc of great socioeconomic importance for the inhabitants of the Eastern Pacific coastline from Baja California in Mexico to Máncora in Peru (Coan & Valentich-Scott, 2012). Despite its cultural importance and consumption, research efforts to foster its production in captivity are scarce. However, it was possible to find a few works in Mexico

“…Early development of oyster is a process that involves gradual and successive changes from pelagic larvae to sessile postlarvae, and the production of healthy seeds in hatcheries depends on the normal metamorphosis of fertilized eggs to larval (i.e., trochophore, D-stage, veliger, and pediveliger) and post-larval (spat) stages (Wallace et al, 2008 ). It is believed that deleterious environmental factors and lack of proper nutrition constitute the most important causes of larval mortalities (Xu et al, 2011 ; Wang et al, 2018 ; Flores-Higuera et al, 2020 ). However, studies continue to confirm the essential roles of commensal microbiota in the survival of the larvae of aquatic animals (Boettcher et al, 2000 ; Xiong et al, 2017 ; Tarnecki et al, 2019 ).…”

Increasing evidence indicates that microbes colonized in early life stages have a long-term effect on animal wellbeing in later life stages. Related research is still limited in aquatic animals, particularly in bivalve mollusks. In this study, we analyzed the dynamics of the bacterial composition of the pelagic larval stages (fertilized egg, trochophore, D-stage, veliger, and pediveliger) and the sessile postlarval stage (spat) of Kumamoto oyster (Crassostrea sikamea) and their relationships with the rearing water bacterioplankton in a hatchery by using Illumina sequencing of bacterial 16S rRNA gene. Both bacterioplankton and larval bacterial communities changed greatly over larval development, and the two communities remarkably differed (r = 0.956, P < 0.001), as highlighted by the differences in the dominant taxa and bacterial diversity. Ecological processes of larval bacterial communities were measured by abundance-unweighted and abundance-weighted standardized effect sizes of the mean nearest taxon distance (ses.MNTD). The unweighted ses.MNTD analysis revealed that the deterministic process constrained the larval bacterial assembly, whereas the weighted ses.MNTD analysis showed that larval bacterial composition was initially governed by stochasticity and then gradually by determinism in the later stages. SourceTracker analysis revealed that the larval bacteria were primarily derived from an internal source, mainly from larvae at the present stage. Additionally, the abundances of larval bacterial-mediated functional pathways that were involved in the amino acid, energy, lipid and carbohydrate metabolisms significantly altered with the larval development. These findings suggest that bacteria assemble into distinct communities in larvae and rearing water in the hatchery system, and the dynamics of bacterial community composition in larvae is likely associated with larval developmental stages.
