Histamine (Scombroid) Fish Poisoning: a Comprehensive Review
Clinical Reviews in Allergy & Immunology, 2016Co-Authors: Charles Feng, Suzanne Teuber, M. Eric GershwinAbstract:Histamine fish poisoning, also known as scombroid poisoning, is the most common cause of ichythyotoxicosis worldwide and results from the ingestion of histamine-contaminated fish in the Scombroidae and Scomberesocidae families, including mackerel, bonito, albacore, and skipjack. This disease was first described in 1799 in Britain and re-emerged in the medical literature in the 1950s when outbreaks were reported in Japan. The symptoms associated with histamine fish poisoning are similar to that of an allergic reaction. In fact, such histamine-induced reactions are often misdiagnosed as IgE-mediated fish allergy. Indeed, histamine fish poisoning is still an underrecognized disease. In this review, we discuss the epidemiology, pathophysiology, evaluation, and treatment of scombroid disease. Because more than 80 % of fish consumed in the USA is now imported from other countries, the disease is intimately linked with the global fish trade (National Marine Fisheries Service, 2012 ). Preventing future scombroid outbreaks will require that fishermen, public health officials, restaurant workers, and medical professionals work together to devise international safety standards and increase awareness of the disease. The implications of scombroid poisoning go far beyond that of fish and have broader implications for the important issues of food safety.

Geographical Distribution and Abundance of Pacific Saury, Cololabis saira (Brevoort) (Scomberesocidae), Fishing Stocks in the Northwestern Pacific in Relation to Sea Temperatures
2007Co-Authors: Wen-bin Huang, Tai-sheng Chiu, Chih-shin ChenAbstract:Geographical distribution and abundance of Pacific saury, Cololabis saira (Brevoort) (Scomberesocidae), fishing stocks in the northwestern Pacific in relation to sea temperatures. Zoological Studies 46(6): xxx-xxx. We compared geographical distributions of Pacific saury, Cololabis saira (Brevoort) (Scomberesocidae), fishing stocks in the Northwest Pacific (NWP) for 3 yearly groups of high, average, and low abundances, using the Taiwanese fishery catch per unit effort (CPUE) data from 1994 to 2002. Two migratory groups, inshore and offshore, were found in average- and low-abundance years, while an additional oceanic migratory group, which spread eastward to around 178°E in Oct., was found in the year of high abundance. Most of the saury groups were distributed in areas where the sea surface temperature (SST) ranged between 10 and 20°C with a high aggregation around 15°C, implying that 15°C is the preferred temperature for saury to aggregate intensively for the commencement of the spawning migration, and to move southward to spawning grounds where SSTs of around 20°C are favorable to their offspring. The timing, abundance, and geographical distributions of fish aggregations of migratory saur

Geographical Distribution and Abundance of Pacific Saury, Cololabis saira (Brevoort) (Scomberesocidae), Fishing Stocks in the Northwestern Pacific in Relation to Sea Temperatures
Zoological Studies, 2007Co-Authors: Wen-bin Huang, Tai-sheng Chiu, Chih-shin ChenAbstract:Wen-Bin Huang, Nancy C.H. Lo, Tai-Sheng Chiu, and Chih-Shin Chen (2007) Geographical distribution and abundance of Pacific saury, Cololabis saira (Brevoort) (Scomberesocidae), fishing stocks in the northwestern Pacific in relation to sea temperatures. Zoological Studies 46(6): 705-716. We compared geographical distributions of Pacific saury, Cololabis saira (Brevoort) (Scomberesocidae), fishing stocks in the Northwest Pacific (NWP) for 3 yearly groups of high, average, and low abundances, using the Taiwanese fishery catch per unit effort (CPUE) data from 1994 to 2002. Two migratory groups, inshore and offshore, were found in averageand low-abundance years, while an additional oceanic migratory group, which spread eastward to around 178 ° E in Oct., was found in the year of high abundance. Most of the saury groups were distributed in areas where the sea surface temperature (SST) ranged between 10 and 20 ° C with a high aggregation around 15 ° C, implying that 15 ° C is the preferred temperature for saury to aggregate intensively for the commencement of the spawning migration, and to move southward to spawning grounds where SSTs of around 20 ° C are favorable to their offspring. The timing, abundance, and geographical distributions of fish aggregations of migratory saury were associated with SSTs. In the early stages of the fishing season, apparent warming caused by the intrusion of Kuroshio Current waters in the southern NWP was closely related to delayed aggregation and low abundances of the saury stock; in contrast, cooling of the waters affected by Oyashio waters was related to eastward aggregation and high abundances of saury. High saury abundances occurred in low-temperature areas. Specifically, in years of low CPUE values, sea water temperatures (SWTs) of the fishing grounds were higher than 15 ° C, while in years of average and high CPUE values, the SWTs of the fishing grounds were < 15 ° C. Therefore, fishing ground SWTs higher than 15 ° C (around 16 ° C SST) is an indicator of low stock abundances of saury in the NWP. http://zoolstud.sinica.edu.tw/Journals/46.6/705.pdf

Infection of the Pacific saury Cololabis saira (Brevoort, 1856) (Teleostei: Beloniformes: Scomberesocidae) by Pennella sp. (Copepoda: Siphonostomatoida: Pennellidae) south of the Subarctic Front
Journal of Crustacean Biology, 2020Co-Authors: Satoshi Suyama, Takashi Yanagimoto, Shigeho Kakehi, Seinen ChowAbstract:Abstract The Pacific saury (Cololabis saira) is a fish of commercial importance subject to unpredictable epidemics of infection by Pennella sp., a parasitic copepod. We analyzed the distribution of fish presenting with newly attached Pennella to determine the region and season in which Pennella first infect the fish. Pacific sauries migrate northward in the spring to spend the summer in the subarctic region, successively crossing the Subarctic Boundary (SAB) and the Subarctic Front (SAF). The fish then return to subtropical waters in the fall and overwinter there. Pacific sauries infected with Pennella were observed on both the north and south sides of the SAF from May to December. Newly attached Pennella, however, were observed mainly to the south of the SAF during the northward migration of the fish in May and June, and only to the south of the SAB during the southward migration in November and December. These results indicate that the intermediate host or hosts of Pennella inhabit the region south of the SAF, with infection of Pacific saury occurring during late fall and spring. Such information may assist in identifying the intermediate host(s).

Genetic and morphological variation in Pennella sp. (Copepoda: Siphonostomatoida) collected from Pacific saury, Cololabis saira
Marine Biodiversity, 2019Co-Authors: Satoshi Suyama, Yoshio Masuda, Takashi Yanagimoto, Seinen ChowAbstract:In this paper, we describe three morphotypes of large parasitic copepods identified as Pennella Oken, 1815 (Siphonostomatoida, Pennellidae), which are found on the commercial fish Pacific saury Cololabis saira (Brevoort, 1856) (Beloniformes, Scomberesocidae). Of three morphotypes ( Pennella sp. (PSP), parasite A (PA), and indeterminate individuals (IDI)), PSP had feather-like abdominal brushes and egg sacs which were characters typical of Pennella , PA lacked abdominal brushes and egg sacs, and IDI had few abdominal brushes but no egg sacs. Nucleotide sequence differences of mitochondrial cytochrome oxidase subunit I (COI) and nuclear ribosomal internal transcribed spacer 1 (ITS1) regions between types were small and comparable with differences within a type, indicating that the three types were conspecific. Mean body length of PSP was significantly larger than those of PA and IDI, suggesting types PA and IDI were immature morphs of PSP or individuals that had ceased development prior to maturation.

Little population structuring and recent evolution of the Pacific saury (Cololabis saira) as indicated by mitochondrial and nuclear DNA sequence data
Journal of Experimental Marine Biology and Ecology, 2009Co-Authors: Seinen Chow, Nobuaki Suzuki, Richard D. Brodeur, Yasuhiro UenoAbstract:Abstract Genetic population structure of the Pacific saury (Cololabis saira) was investigated using nucleotide sequence analysis on the mitochondrial DNA control region (355-361 bp). Although the left domain of the control region is known to be highly variable in many species, extremely low nucleotide and haplotype diversities (π = 0.17% and h = 0.418, respectively) were observed in a total of 141 individuals collected from five distant locales (East China Sea, Sea of Okhotsk, northwest Pacific, central North Pacific and northeast Pacific). No significant haplotype frequency differences were detected among widely separated samples, therefore we were unable to reject the null hypothesis of no genetic structuring in the Pacific saury population. Moderate levels of nucleotide substitution (p-distance) were observed between the Pacific saury and its Atlantic counterpart (Scomberesox saurus) in the control region (7.44%), cytochrome b gene (4.64%), and internal transcribed spacer (ITS1) (11.49%), indicating that the low sequence diversity of the control region in the Pacific saury is not due to the slow mutation rate. The molecular data suggest the Pacific saury may be a relatively recent offshoot among the extant members in the family Scomberesocidae.

Phylogeny and Jaw Ontogeny of Beloniform Fishes
Integrative and Comparative Biology, 2004Co-Authors: Nathan R Lovejoy, Mahmood Iranpour, Bruce B. ColletteAbstract:Abstract To investigate jaw evolution in beloniform fishes, we reconstructed the phylogeny of 54 species using fragments of two nuclear (RAG2 and Tmo-4C4) and two mitochondrial (cytochrome b and 16S rRNA) genes. Our total molecular evidence topology refutes the monophyly of needlefishes (Belonidae) and halfbeaks (Hemiramphidae), but supports the monophyly of flyingfishes (Exocoetidae) and sauries (Scomberesocidae). Flyingfishes are nested within halfbeaks, and sauries are nested within needlefishes. Optimization of jaw characters on the tree reveals a diverse array of evolutionary changes in ontogeny. During their development, needlefishes pass through a “halfbeak” stage that closely resembles the adult condition in the hemiramphid halfbeaks. The reconstruction of jaw transitions falsifies the hypothesis that halfbeaks are paedomorphic derivatives of needlefishes. Instead, halfbeaks make up a basal paraphyletic grade within beloniforms, and the needlefish jaw morphology is relatively derived. The parallel...

Reinterpreting recapitulation: systematics of needlefishes and their allies (Teleostei: Beloniformes).
Evolution, 2000Co-Authors: Nathan R LovejoyAbstract:Abstract As needlefishes (Belonidae) grow, their jaws pass through a “halfbeak” stage that resembles the adult jaw condition of the closely related family of halfbeaks (Hemiramphidae). Based on this pattern, some authors have suggested that halfbeaks are “developmentally arrested” or paedomorphic needlefish derivatives, whereas others have supported the notion that needlefishes are descended from halfbeak-like ancestors and that needlefish ontogeny thereby recapitulates phylogeny. To test these ideas and to better understand evolutionary changes in jaw ontogeny, phylogenetic relationships among genera of needlefishes, sauries (Scomberesocidae), halfbeaks, and flyingfishes (Exocoetidae) were assessed using mitochondrial (cytochrome b and 16S), nuclear (Tmo-4C4), and morphological characters. The resultant tree provides several novel taxonomic findings: (1) flyingfishes appear to be nested within halfbeaks; (2) sauries appear to be nested within needlefishes; and (3) the Indo-West Pacific freshwater halfbea...
