Growing knowledge of the host-microbiota vertebrates has shown prevalence sex-specific differences in microbiome. However, there are virtually no studies assessing sex-associated variation microbiome cephalopods. Here we assess common octopus ( Octopus vulgaris ) skin using amplicon sequencing targeting V4 hypervariable region prokaryote 16S rRNA genes. Skin and mantle-associated mucus was collected from wild adult individuals (9 males 7 females similar size). There were significant alpha...
There has been a great interest in common octopus Octopus vulgaris aquaculture over recent years and commercial production is coming within reach. In addition, O. short-lived semelparous species with long spawning period. Therefore, monitoring ovary maturation cultured octopuses can be useful the scheduling of hatchery operations management culture resources. The present work aimed to assess maturity status wild by means noninvasive technique, ultrasonography, anticipate time aquaculture. A...
Coleoid cephalopods such as the common octopus have a complex visual system, with camera-type eye and large optic lobe, that evolved independently from its counterpart in vertebrates. However, molecular neurochemical basis of signalling Octopus circuits is not well understood. Through heterologous expression ligand-gated ion channel genes vulgaris, we identified characterised novel ionotropic receptors for two major lobe neurotransmitters, dopamine acetylcholine. One these, DopC1, defines...
In female sea bream Sparus aurata fed a control diet (C), ovarian levels of neutral lipids (NL) and polar (PL) remained constant between November March, while decrease in NL content was observed liver muscle. the same period, PL increased, no changes were Between March June showed strong decrease, When fish lacking n‐3 highly unsaturated fatty acids, HUFA (D), pattern similar to that found C, with exception NL, which increased June. general, acid content, both groups fish, influenced by...
This study demonstrates the daily deposition of increments in Octopus vulgaris beaks for both lateral wall surfaces (LWS) and rostrum sagittal sections (RSS). Forty-nine marked wild animals kept aquaria (weight range, 158–3,521 g) 24 captive-reared known-age individuals (paralarvae, 0–98 days old; adults, 200–734 old) were studied, encompassing first time full age range species, including older than 1 mo. The beak was validated LWS by injection Calcofluor, RSS environmental marking (thermal,...
Octopus vulgaris has been an iconic cephalopod species for neurobiology research as well aquaculture. It is one of the most intelligent and well-studied invertebrates, possessing both long- short-term memory striking ability to perform complex cognitive tasks. Nevertheless, how common octopus developed these uncommon features remains enigmatic. O. females spawn thousands small eggs remain with their clutch during entire development, cleaning, venting protecting eggs. In fact, incubated...
Abstract The common octopus ( Octopus vulgaris , Cuvier 1797) is a promising species for aquaculture diversification, but the massive mortality during first life stage main bottleneck its commercial production. aim of present study was to compare effects different live preys Artemia and crustacean zoeae) and/or enrichment protocols in paralarval growth by using meta‐analysis approach. A total 26 independent assays were used, including data from bibliography experiments carried out our group....
Abstract Common octopus, Octopus vulgaris , is an economically important cephalopod species. However, its rearing under captivity currently challenged by massive mortalities previous to their juvenile stage due nutritional and environmental factors. Dissecting the genetic basis regulatory mechanism behind this mortality requires genomic background knowledge. A transcriptomic sequencing of 10 dph octopus paralarvae from different experimental conditions was constructed via RNA-seq. total...
In this study, two new alternative preys: Grapsus adscensionis zoeae (as sole prey) and Palaemon elegans (in cofeeding with Artemia sp.), as well as, sp. juveniles were used feed for octopus paralarvae, a way to understand its lipid requirements. Total (TL) content, class (LC) fatty acid (FA) profiles of preys, hatchlings 9-day-old paralarvae analysed. Growth survival the also determined. Regardless prey provided, notable shift in profile was registered after 9 days rearing. The highest...
