Evidence supporting the occurrence and the ecological implication of giant mottled eel, Anguilla marmorata (Actinopterygii: Anguilliformes: Anguillidae), from Sabah, Borneo Island. Acta Ichthyol. 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. The presently reported study represents the first description of A. marmorata in Sabah, Borneo Island. One-year survey suggests that representatives of A. marmorata found in the region might belong to the North Pacific population in the westernmost distribution.

The identification of eels at the species level using solely visual observation is suggested to be difficult South China because of the similarities and overlapping morphological Sea characteristics in eels, particularly tropical anguillids (Arai et al. 2015, Arai 2016, Arai and Wong 2016). Furthermore, such information about the geographical distribution, species composition, and life history is available in the limited area and little information is still available for Papar River many tropical eels across the Indo-Pacific region. In the presently reported study, we surveyed and collected two anguillid eels during a one-year sampling in Sabah, Borneo Island. These eels were subjected to identification using both morphological analyses and mitochondrial 16S ribosomal RNA (16S rRNA) sequence analyses.

A total of nine local authorities were studied. Data was mainly obtained from interviews, observations and written sources. The variation in the Campaign implementation progress can be explained in term of campaign internalization among local authority top leadership. Internalization is reflected in the understanding of the campaign and priority of local government top leaderships observed in their actions, choice of words and activities. In addition, the structure of the local authority also influenced implementation progress. © 2013 The Authors.

  • 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).

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.

They are good source of animal protein and bear high food values. Dwindling population of eels has meanwhile led certain species to IUCN threatened categories. In spite of these, scientifi c investigations on the only species of this genus, Anguilla bengalensis, in this region have not been reported much. Many biological questions of the catadromous fi sh are still unanswered. Quick but authentic identifi cation of threatened species is vital to unveil such query and frame out conservation and management strategies. DNA barcodes utilising partial mitochondrial cytochrome c oxidase I gene and nuclear rhodopsin gene were developed in this current study. Conventional taxonomic information has also been included contemplating inevitable role of it in unambiguous species level discrimination. The study has generated novel barcode of the species from this region to decipher implications on congeneric and conspecifi c divergence.
