“…Given their small size, Dorvilleids have never been an important commercial group. However, a recent study suggested the beneficial use of Ophryotrocha species in pisciculture by feeding on fish feces and in turn being fed to the fish [117]. In addition, because they have a short generation time and are easily kept in laboratory conditions, Ophryotrocha species may be suitable candidates as test model organisms for various kinds of studies [70,79,87,118].…”

The Current State of Eunicida (Annelida) Systematics and Biodiversity

In this study, we analyze the current state of knowledge on extant Eunicida systematics, morphology, feeding, life history, habitat, ecology, distribution patterns, local diversity and exploitation. Eunicida is an order of Errantia annelids characterized by the presence of ventral mandibles and dorsal maxillae in a ventral muscularized pharynx. The origin of Eunicida dates back to the late Cambrian, and the peaks of jaw morphology diversity and number of families are in the Ordovician. Species richness is heterogeneous among the seven recent families, with more than half of the valid species belonging to the Eunicidae + Onuphidae clade, one of the latest clades to diverge. Eunicidans inhabit soft and hard substrates from intertidal to deep waters in all oceans. The few freshwater species are restricted to Histriobdellidae, a family exclusively commensal/parasite of crustaceans. The reproductive biology, development and ecology of most families are poorly known and the information available suggests low dispersal ability. However, all families have records of widely distributed species. Scrutiny of these wide distributions has often revealed the presence of exotic species or more than one species. The exploration of the deep-sea and of new habitats has led to recent descriptions of new species. Furthermore, the revision of type specimens, the examination of new morphological features and the use of molecular data have revealed hidden biodiversity under unjustified synonyms, poor understanding of morphological features and incomplete descriptions. Molecular studies are still very few or nonexistent for the families Histriobdellidae, Hartmaniellidae, Lumbrineridae and Oenonidae. The integration of new methodologies for morphological and molecular study, along with information on biological and ecological traits appears to be the path to improve the knowledge on the diversity of Eunicida.

“…Trays were placed (a) on the south side of each of the 8 salmon cages, and (b) additional trays were placed on the north side below cages 1, 2, 4 and 8. The quality of video recordings of Tray 1a, 2b and 5a was not sufficient for categorizing the tray coverage and they were therefore omitted and thereby in waste decomposition (Salvo et al 2015, Nederlof et al 2019. Either way, Eikje (2013) re ported a significant increase in population size throughout a salmon production cycle but also a steep decrease after the fish were harvested and orga nic loading disappeared.…”

“…cultured under a shallow fish farm in Japan (Kinoshita et al 2008). Furthermore, the body composition of O. craigsmithi seems interesting as an alternative high-quality marine resource (Nederlof et al 2019). The deployment of benthic trays has been shown to attract dense Ophryotrocha communities, indicating that the alternative IMTA concept of enhancing indigenous species may be a promising approach for benthic cultivation in integrated open water systems.…”

“…Marine polychaetes have been often pinpointed as holding great potential to recover wasted nutrients from POM with species such as Hediste diversicolor 9 , 20 – 25 , Perinereis aibuhitensis 26 , Alitta virens 26 , 27 , Perinereis nuntia 28 , 29 , Perinereis helleri 29 , 30 , Arenicola marina 26 , Abarenicola pusilla 31 , 32 , Capitella sp. and Ophryotrocha craigsmithi 33 already being tested under IMTA designs. These marine worms have already been successfully combined with organisms that may retain dissolved inorganic nutrients efficiently, such as macro and microalgae 22 , 23 , as well as halophytes 9 .…”

Polychaete assisted sand filters (PASFs) allow to combine a highly efficient retention of particulate organic matter (POM) present in aquaculture effluent water and turn otherwise wasted nutrients into valuable worm biomass, following an integrated multi-trophic aquaculture (IMTA) approach. This study evaluated the bioremediation and biomass production performances of three sets of PASFs stocked with ragworms (Hediste diversicolor) placed in three different locations of an open marine land-based IMTA system. The higher organic matter (OM) recorded in the substrate of the systems which received higher POM content (Raw and Df PASFs – filtered raw and screened by drum filter effluent, respectively) likely prompted a superior reproductive success of stocked polychaetes (final densities 2–7 times higher than initial stock; ≈1000–3000 ind. m−2). Bioremediation efficiencies of ≈70% of supplied POM (≈1.5–1.8 mg L−1) were reported in these systems. The PASFs with lower content of OM in the substrate (Df + Alg PASFs – filtered effluent previously screened by drum filter and macroalgae biofilter) differed significantly from the other two, with stocked polychaetes displaying a poorer reproductive success. The PASFs were naturally colonized with marine invertebrates, with the polychaetes Diopatra neapolitana, Terebella lapidaria and Sabella cf. pavonina being some of the species identified with potential for IMTA.
