Nine species of copepods in the family Lernaeopodidae were collected as parasites of teleost or elasmobranch fishes common to coastal waters of British Columbia. One species (Schistobrachia tertia) has not been previously described. Two species (Dendrapta cameroni longiclavata and Lernaeopodina pacifica) are new records for the Canadian fauna. The remaining six include Pseudocharopinus dentatus, Clavella adunca, and detailed descriptions of Clavella parva, Clavella perfida, Nectobranchia indivisa, and Brachiella robusta, the last-named displaying a range of morphological variability hitherto unknown in Lernaeopodidae.

Identification of the Mallomonadaceae of selected lakes in British Columbia reveals 20 species of the genera Chromophysomonas, Chrysosphaerella, Mallomonas, Mallomonopsis, Paraphysomonas, and Synura. The following eight taxa in the family are new records for British Columbia (* indicates those new to North America): Mallomonas asmundiae, M. doignonii var. tenuicostis, M. papillosa, M. transsylvanica, Mallomonopsis ouradion*, Paraphysomonas vestita, Synura glabra, S. splendida*. Thirteen additional Chrysophyceae were also present, with the most diversity observed being in the three lakes studied extensively (Whonock, Como, Munday).

Background. The Gracilariaceae is one of the most diverse and abundant families of marine red algae. Most species in this family exhibit high morphological variability and overlapping of characters. In the Yucatan Peninsula 30 species have been historically recorded, but the phylogenetic identity for many of them is still unknown. Questions: Is the current diversity of the family in the area overestimated? Studied species: Crassiphycus caudatus, C. corneus, C. usneoides, Gracilaria flabelliformis, G. hayi, G. cf isabellana, G. microcarpa, G. occidentalis, G. suzanneae, Gracilariopsis tenuifrons. Study site and dates: Campeche: km 33 carretera Champotón, Bahía Tortuga, Puente Xen Kan III, Punta Xen, Sabancuy, 2017, 2018; Yucatan: Puerto Sisal, Puerto Progreso, Puerto Chicxulub, Puerto Telchac, 2018; Quintana Roo: Playa 88, Xcalacoco, Punta Esmeralda, 2019. Methods. Phylogenetic analysis (with COI-5P and rbcL sequences), supported by DNA species delimitation methods, genetic distances and morphological comparisons, allowed us to molecularly identify the specimens collected. Results. The phylogenetic identity of 10 species of Gracilariaceae was confirmed, two of which are new records for the Mexican Atlantic: G. hayi and G. suzanneae. Conclusion. The study demonstrated that the molecular assessment has proved to be very useful for the diversity evaluation, thus, the future phylogenetic identifies for the rest of morphospecies recorded in the area will allow a better approximation of Gracilariaceae diversity species.

Floristic Treatment

This is a floristic treatment of benthic marine red algae (Rhodophyta) in the order Palmariales that occur in British Columbia and northern Washington. Seven species (including one new species of Palmaria) in four genera are recorded as follows: Halosacciocolax kjellmanii Lund, Halosaccion glandiforme (S. G. Gmelin) Ruprecht, Palmaria callophylloides Hawkes et Scagel, sp. nov., P. hecatensis Hawkes, P. mollis (Setchell et Gardner) van der Meer et Bird, Rhodophysema elegans (P. L. et H. M. Crouan ex J. Agardh) P. S. Dixon, and R. georgii Batters. Rhodophysema minus Hollenberg et Abbott is treated as a taxonomic synonym of R. elegans. An historical background of the Palmariales is provided. Also provided are revised circumscriptions of the family Palmariaceae and genera Palmaria, Halosaccion, and Rhodophysema based on recent life-history studies by other workers that demonstrate the presence of sexual reproduction in several palmarialean taxa. Keys to and descriptions of taxa (at the ordinal, familial, generic, and specific levels), as well as information on synonyms, location of type specimens, type localities, and what is known about the life histories, distribution, seasonality, and habitats of all taxa, are provided. References are given, and representative specimens are cited that document our concept of the taxa and their morphological variability, seasonality, and geographical distributions.

ABSTRACT Viruses infecting the harmful bloom-causing alga Phaeocystis globosa (Prymnesiophyceae) were readily isolated from Dutch coastal waters (southern North Sea) in 2000 and 2001. Our data show a large increase in the abundance of putative P. globosa viruses during blooms of P. globosa, suggesting that viruses are an important source of mortality for this alga. In order to examine genetic relatedness among viruses infecting P. globosa and other phytoplankton, DNA polymerase gene (pol) fragments were amplified and the inferred amino acid sequences were phylogenetically analyzed. The results demonstrated that viruses infecting P. globosa formed a closely related monophyletic group within the family Phycodnaviridae, with at least 96.9% similarity to each other. The sequences grouped most closely with others from viruses that infect the prymnesiophyte algae Chrysochromulina brevifilum and Chrysochromulina strobilus. Whether the P. globosa viruses belong to the genus Prymnesiovirus or form a separate group needs further study. Our data suggest that, like their phytoplankton hosts, the Chrysochromulina and Phaeocystis viruses share a common ancestor and that these prymnesioviruses and their algal host have coevolved.

Finfish Aquaculture

Parasitic copepods of the family Caligidae, the so-called sea lice, may be deleterious to marine or brackish finfish aquaculture. To date, biological and ecological studies of sea lice have been mostly restricted to species from cold or temperate regions. In Mexico there are some records of sea lice species on marine fishes; however, the research regarding their biology and ecology has been scarce. It is possible that a high biodiversity of sea lice is distributed in coastal waters of Mexico; therefore, their significance as pathogenic parasites should increase. The purpose of this review is to outline the current knowledge of the life cycle, host location, ecology, effect on fish health, and control strategies of sea lice in order to establish supportive basis for natural resource management and control of parasites and diseases of marine fish cultured in Mexico.

This paper reports on mites of the family Pachylaelapidae collected in Bayburt Province, Turkey, during 2013–2015. Nine species were recorded in the genera Pachyseius, Olopachys, Pachylaelaps, and Onchodellus. Pachylaelaps (Longipachylaelaps) bayburtensis sp. nov., Onchodellus turcicus sp. nov. and O. montanus sp. nov. are described to new, and Pachylaelaps (Longipachylaelaps) vicarus is a new record for the Turkish mite fauna. New records extend the geographic range of Pachyseius masani, Olopachys hallidayi, and O. elongatus in Turkey.
