Artificial Completion of the Japanese Eel, , Life Cycle: Challenge to Mass

No. 35, 111-117, 2012 111 Artificial Completion of the Japanese Eel, Anguilla japonica, Life Cycle: Challenge to Mass Production *1 *1 *2 *1 Yoshitsugu MASUDA , Hitoshi IMAIZUMI , Kentaro ODA , Hiroshi HASHIMOTO , *3 *4 Hironori USUKI , and Kazuhisa TERUYA Abstract:Current eel culture depends entirely on glass eels captured from the wild. How- ever, in recent decades, eel populations have declined. Thus, establishment of the technol- ogy for producing sustainable supplies of eel seeds is required. To achieve that end, selec- tive breeding and mass production of glass eels is necessary. This year, we were successful in closing the Japanese eel life cycle. However, we have not as yet established techniques for mass production of glass eels because of various technical difficulties. In this paper, we describe the significance of closing the eel life cycle and the challenges that need to be over- come in order to develop a system of glass eel mass production. Key words:ell culture, glass ell production, ell life cycle, Anguilla japonica The mysterious life cycle of eels has attracted maintained the availability of eels to consumers many researchers. For a long time, no one could at reasonable prices. However, current eel culture find eel eggs or larvae in the habitats where the depends entirely on glass eels captured from the adults were found; such as rivers, ponds, coastal wild. A decrease in the availability of glass eels waters. Early in the 20th century, Schmidt (1922) and increase in demand for eels in the marketplace conducted numerous expeditions and discovered will inevitably lead both to increased prices and that the spawning area for both the European eel decreased natural eel stocks. -

A complex life cycle The American eel is the only species in the Gulf of Maine that spends most of its life in fresh water but spawns at sea (a life cycle known as catadromy). American eels are born in the Sargasso Sea, a large area of the Atlantic Ocean south of Bermuda and east of the Bahamas. American eel larvae (known as leptocephali) are transported by ocean currents for nearly a year until they reach the east coast of North America. As they near the coast, leptocephali metamorphose into an early juvenile stage known as a glass eel.

Piscat. 47 (1): 73–79. Abstract. Although tropical anguillid eels account for two-thirds of all species in the genus Anguilla, the information on the species diversity, geographic distribution, and life histories of the tropical eels is very limited. Recent studies suggested that accurate species identification in the tropical anguillid eels needs a validation by molecular genetic analysis after morphological observation. Two anguillid eels found in Sabah, Borneo Island, were firstly identified as Anguilla marmorata Quoy et Gaimard, 1824 using morphological analysis and further analysis of mitochondrial 16S ribosomal RNA (16S rRNA) sequences confirmed the morphological species identification.

True Eels Or Freshwater Eels - Anguillidae
ISSN 0859-290X, Vol. 5, No. 1 – September 1999 [Supplement No. 6] Even if the eels, in the perception of most people, constitute a readily recognizable group of elongated and snakelike fish, the eels do not constitute a taxonomic group. There is considerable confusion related to eels. See the following system used in "Fishes of the Cambodian Mekong" by Walther Rainboth (1996). In the Mekong, two orders (Anguilliformes and Synbranchiformes) including five eel-Iike fish families are represented: The true eels (Anguillidae), the worm eels (Ophichthidae), the dwarf swamp eels (Chaudhuriidae), the swamp eels (Synbranchidae), and the spiny eels (Mastacembelidae). Of these, the swamp eels and spiny eels are by far the most important in the fisheries. True eels or Freshwater eels - Anguillidae The name "freshwater eels", is not a good name to describe the habits of the species in this family. All the anguillid species are catadromous (a catadromous fish is bom in the sea, but lives most of its life in fresh water). The sexually mature fish migrate down to the sea to spawn, and the juveniles ("the elvers") move, sometimes for a considerable distance, up the river to find their nursery areas. The true eels, contrary to most of the other Mekong eels, have two gill openings, which are high on each side of the fish. The body is covered with small scales that are deeply embedded in the skin. Pelvic fins are absent, while pectoral fins are well developed. The long dorsal and anal fins are continuous with the caudal fin, and the fins are not preceded by any spines. -

Introduction Very little was known about the freshwater ecosystems of the Commonwealth of the Northern Marianna Islands (CNMI) or the species that inhabit them prior to this study. Most information was both unpublished and anecdotal (Best 1981). Derek Stinson put a report together nearly twenty years ago, which defines most of the major wetland areas of the CNMI and provides some background information for larger lentic systems like Lake Susupe, but doesn’t mention any of our interstitial stream systems (Stinson 1990). An examination of freshwater fishes in the CNMI using Fishbase, a comprehensive fisheries web resource, lists 13 native and 2 introduced species (Froese 2008). -

Original language: English CoP17 Doc. 51 CONVENTION ON INTERNATIONAL TRADE IN ENDANGERED SPECIES OF WILD FAUNA AND FLORA ____________________ Seventeenth meeting of the Conference of the Parties Johannesburg (South Africa), 24 September – 5 October 2016 Interpretation and implementation matters Species specific matters CONSERVATION OF AND TRADE IN ANGUILLA SPP. 1. This document has been submitted by the European Union.* Background 2. International trade in Anguilla species 1 has existed for decades and includes products related to aquaculture, food and accessories. Harvest of the species for this trade and domestic use, combined with a number of other threats such as barriers to migration, habitat loss, turbine mortality, pollution, disease and parasites, predators have reduced some Anguilla species populations to levels requiring that their trade is controlled in order to avoid utilization incompatible with their survival. However, once collection and/or trade in one Anguilla species is regulated due to population declines, the demand is redirected to other species. There is therefore an urgent need to consolidate data on trade and management of Anguillid eels so they can be sustainably managed as a group. 3. The European eel (Anguilla anguilla) was listed in CITES Appendix II at CoP14 and the listing came into force in 2009. The biological status of the species has notably been monitored for years by the ICES/GFCM/EIFAAC2 Working Group on Eels (WGEEL). Due to its depleted status within Europe, the EU has been unable to make a positive non-detriment finding for the species since December 2010. Currently export and import of this species from and into the EU is not permitted, and all EU Member States have published a zero export quota for European Eel since 2011. -
A Checklist of the Parasites of Eels (Anguilla Spp.) (Anguilliformes: Anguillidae) in Japan (1915-2007)
J. Grad. Sch. Biosp. Sci. Hiroshima Univ. (2007), 46:91~121 REVIEW A Checklist of the Parasites of Eels (Anguilla spp.) (Anguilliformes: Anguillidae) in Japan (1915-2007) 1) 1) 2) Kazuya Nagasawa , Tetsuya Umino and Kouki Mizuno 1)Graduate School of Biosphere Science, Hiroshima University 1-4-4 Kagamiyama, Higashi-Hiroshima, Hiroshima 739-8528, Japan 2)Ehime Prefectural Uwajima Fishery High School 1-2-20 Meirin, Uwajima, Ehime 798-0068, Japan Abstract Information on the protistan and metazoan parasites of three species of eels, the Japanese eel Anguilla japonica, the giant mottled eel A. marmorata and the European eel A. anguilla, in Japan is summarized in the Parasite-Host List and Host-Parasite lists, based on the literature published for 93 years between 1915 and 2007. Both A. japonica and A. marmorata are native to Japan, whereas A. anguilla is an introduced species from Europe. The parasites, including 44 named species and those not identified to species level, are listed by higher taxon as follows: Sarcomastigophora (no named species), Ciliophora (6), Microspora (1), Myxozoa (6), Trematoda (7), Monogenea (7), Cestoda (3), Nematoda (7), Acanthocephala (4), Hirudinida (2), and Copepoda (1). For each taxon of parasite, the following information is given: its currently recognized scientific name, any original combination, synonym(s), or other previous identification used for the parasite occurring in eels; habitat (freshwater, brackish, or marine); site(s) of infection within or on the host; known geographical distribution in Japanese waters; and the published source of each locality record. Of the 44 named species of parasites, 43 are from A.
