“…Since harpacticoid copepods are able to cling very tightly to algae (Monk 1941cited in Yeatman 1962) they seem to be well equipped for rafting on macroalgae. The same behaviour has been described for nauplii of Tisbe furcata by Johnson & Olson (1948). This species produces benthic larvae that use their prehensile hooks and second antennae to cling tightly to detritus particles.…”

Rafting of marine and terrestrial organisms has been reported from a variety of substrata and from all major oceans of the world. Herein we present information on common rafting organisms and on ecological interactions during rafting voyages. An extensive literature review revealed a total of 1205 species, for which rafting was confirmed or inferred based on distributional or genetic evidence. Rafting organisms comprised cyanobacteria, algae, protists, invertebrates from most marine but also terrestrial phyla, and even a few terrestrial vertebrates. Marine hydrozoans, bryozoans, crustaceans and gastropods were the most common taxa that had been observed rafting. All major feeding types were represented among rafters, being dominated by grazing/boring and suspension-feeding organisms, which occurred on all floating substrata. Besides these principal trophic groups, predators/scavengers and detritus feeders were also reported. Motility of rafting organisms was highest on macroalgae and lowest on abiotic substrata such as plastics and volcanic pumice. Important trends were revealed for the reproductive biology of rafting organisms. A high proportion of clonal organisms (Cnidaria and Bryozoa) featured asexual reproduction, often in combination with sexual reproduction. Almost all rafting organisms have internal fertilisation, which may be due to the fact that gamete concentrations in the rafting environment are too low for successful fertilisation of external fertilisers. Following fertilisation, many rafting organisms incubate their offspring in/on their body or deposit embryos in egg masses on rafts. Local recruitment, where offspring settle in the immediate vicinity of parents, is considered an important advantage for establishing persistent local populations on a raft, or in new habitats. Some organisms are obligate rafters, spending their entire life cycle on a raft, but the large majority of reported rafters are considered facultative rafters. These organisms typically live in benthic (or terrestrial) habitats, but may become dispersed while being confined to a floating item. Substratum characteristics (complexity, surface, size) have important effects on the composition of the rafting community. While at sea, ecological interactions (facilitation, competition, predation) contribute to the community succession on rafts. Organisms capable to compete for and exploit resources on a raft (space and food) will be able to persist throughout community succession. The duration of rafting voyages is closely related to rafting distances, which may cover various geographical scales. In chronological order, three features of an organism gain in importance during rafting, these being ability to (1) hold onto floating items, (2) establish and compete successfully and (3) develop persistent local MARTIN THIEL & LARS GUTOW 280 populations during a long voyage. Small organisms that do not feed on their floating substratum and, with asexual reproduction or direct development, combine all these features appear to be mos...

“…Lang (1948) Tisbe elongata (A. Scott, 1896) Occurrence. All stages from the' Nauplius V' (that is, a stage corresponding to the one described as Nauplius V for T.jurcata by Johnson & Olson, 1948) to adults were found among the gills of the common lobster (Homarus vulgaris M. Edwards) at Plymouth. The copepods were very abundant, averaging nearly fifty per host; and each lobster examined over a period of about a year was infected.…”

The adults of three new cyclopoid copepods are described and figured, namelyMicropontius ovoides, gen. et sp.nov., occurring on spatangid echinoids;Lichomolgus leptodermatus, sp.nov., andConchyliurus cardii, sp.nov., both associated with pelecypod molluscs.Micropontiusis made the type of a new family, the Micropontiidae.Some other copepods,Asterocheres violaceus(Claus),Scottomyzon gibberum(T. & A. Scott),Pseudanthessius liber(Brady & Robertson),Bomolochus confususStock,Euryte longicaudaPhilippi var.minorT. Scott andPeniculus fistulaNordmann, are recorded for the first time from the Plymouth region; and mention is also made ofTisbe elongata(A. Scott).Points of interest in the biology, morphology, systematics and distribution of all these are discussed.

“…The most prevalent copepods, T. furcata and H. uniremis, are commonly associated with macrophytes (Johnson and Olson 1948;Jewett and Feder 1977;Webb and Parsons 1992). These species were also found attached to the body and gills of the great spider crab Hyas araneus in Dalnezelenetskaya Bay.…”

“…This was probably due to differences in the biotic requirements of this species. T. furcata and H. uniremis usually inhabit a water layer far from the bottom and are frequently found in zooplankton samples (Johnson and Olson 1948;Jewett and Feder 1977;Dvoretsky and Dvoretsky 2010b); thus, they may infest crabs as a result of being drawn into the gills during host respiration activity. D. vulgaris, in contrast, is a more benthic species (Kornev and Chertoprud 2008) and more often infests the host when P. camtschaticus moves along the sea floor.…”

Background: There are no data on copepod occurrence, infestation indices, and localization on red king crabs in the Russian part of the Barents Sea. For this reason, we examined the species composition, infestation indices, and localization patterns of copepods colonizing the red king crab Paralithodes camtschaticus in Dalnezelenetskaya Bay, a small gulf in the Barents Sea. Results: In total, nine species of Copepoda were found on hosts in July of 2009~2011. Typical planktonic copepods (Calanus, Microsetella, and Microcalanus) and some benthopelagic and benthic species (Ectinosoma, Cyclopina, and Zaus) were found in low occurrences; their prevalences did not exceed 5%, and these copepods should be considered incidental visitors. The benthopelagic harpacticoid copepods Tisbe, Harpacticus, and Dactylopusia were the most abundant, with high prevalences and mean intensities of infestation, and should be classified as commensals. Infestation indices were correlated with the host size and shell condition. The majority of copepods were found on host gills (90%~100%). We suggest that the recorded absence of symbiotic copepods from crab branchial chambers in our previous studies in August of 2004~2008 may be explained by predation or competition with the symbiotic amphipod Ischyrocerus commensalis, which was confirmed by analysis of amphipod gut contents. Conclusions: This report expands our knowledge on the colonization of different fouling and symbiotic species on red king crabs. Our study has management and aquaculture implications as it sheds light on possible interactions between copepods and their crab hosts. Colonization of crabs in general may be beneficial for the copepod species because it enhances food acquisition, increases their mobility, and affords them a degree of protection from predators. Conversely, this association may have negative effects on the crab host due to a decrease in respiratory function.
