  • (Australia) Ecological Risk Management Report for The
    CCSBT-ERS/1203/Info18 Ecological Risk Management REPORT FOR THE EASTERN TUNA AND BILLFISH FISHERY May 2009 CCSBT-ERS/1203/Info18 Summary of priority issues for managing the ecological effects of fishing in the ETBF The Ecological Risk Assessment (ERA) process was designed to assess and rank the ecological effects of fishing in Commonwealth fisheries. The process provided a list of species, habitats and ecological communities that are at risk of ecological damage from the effects of fishing. This Ecological Risk Management (ERM) report provides how AFMA will respond to these high risk environmental components. The ecological effects of fishing in the Eastern Tuna and Billfish Fishery (ETBF) are largely due to the incidental capture of non-target species (including the capture of protected species). The methods of fishing employed in the ETBF (pelagic longline, handline, trolling, polling and rod and reel) were found to have little to no direct impact on the physical marine environment. The ETBF is a fishery which targets tuna and tuna-like species; however historical observer and logbook data show that around 103 species are taken, many in small amounts, each year. AFMA aims to implement measures which ensure that the take of commercial species is sustainable and minimises the interactions and mortality of species that are not commercially utilised. The ERA process analysed the effect of commercial fishing in the ETBF, based on the effects on all organisms (protected species, bycatch, byproduct and target species), habitats and ecological communities that occur in the area of the fishery. The highest level of assessment conducted on the ETBF was a quantitative Level 3 assessment.

  • Movement, Home Range and Site Fidelity of the Weedy Seadragon
    Environmental Biology of Fishes 70: 31–41, 2004. © 2004 Kluwer Academic Publishers. Printed in the Netherlands. Movement, home range and site fidelity of the weedy seadragon Phyllopteryx taeniolatus (Teleostei: Syngnathidae) Jaime Sanchez-Camaraa & David J. Boothb aDepartment of Animal Biology (Invertebrates), Faculty of Biology, University of Barcelona 645 Diagonal Ave, Barcelona 08028, Spain (e-mail: [email protected]) bDepartment of Environmental Sciences, University of Technology, Sydney, Westbourne Street, Gore Hill, NSW 2065, Australia Received 20 November 2002 Accepted 4 August 2003 Key words: common seadragon, conservation management, elastomer tagging, persistence, reproduction-related movement Synopsis We measured for the first time movement, home range and site fidelity of the protected and endemic Australian fish weedy seadragon Phyllopteryx taeniolatus. Ninety-two individuals were identified using visual implant fluorescent elastomer and studied over a one-year period. Identified animals remained at the same site over the year within limited home ranges. These home ranges and the movement patterns recorded were independent of sex although movement to shallow sheltered waters to hatch the young was observed at the end of the breeding season for some pregnant males. The site fidelity and restricted home range of the weedy seadragon, as well as the reproduction-related movement have implications for effective management of this protected species. Introduction of captive seahorses (e.g. Payne & Rippingale 2000, Woods 2000). The common or weedy seadragon Phyllopteryx One of the limitations of studying syngnathids in the taeniolatus is the only member of the genus field is that their unusual morphology of body plates Phyllopteryx (Family Syngnathidae) and, along with makes the use of long-term reliable tagging techniques the leafy seadragon Phycodurus eques, are the only difficult (Woods & Martin-Smith in press).

  • P. 1 Doc. 11.36 CONVENTION on INTERNATIONAL TRADE
    Doc. 11.36 CONVENTION ON INTERNATIONAL TRADE IN ENDANGERED SPECIES OF WILD FAUNA AND FLORA ____________________ Eleventh meeting of the Conference of the Parties Gigiri (Kenya), 10-20 April 2000 Interpretation and implementation of the Convention TRADE IN SEAHORSES AND OTHER MEMBERS OF THE FAMILY SYNGNATHIDAE 1. This document has been submitted by the United States of America and Australia. The Secretariat is grateful to the United States of America for providing the Spanish translation and to Australia for providing the French translation. Purpose 2. The intent of the United States and Australia in requesting that this issue be discussed by the Conference of the Parties is to: a) establish dialogue between Party members, concerned scientists, interested industry members, and communities; b) further encourage continued research to clarify taxonomic discrepancies and compile species distribution and demographic data; and c) further encourage the collection of data quantifying international trade, documenting catches by species, as well as data that will provide the best information about the current status of these species and impact trade has on syngnathid populations and their environments. Introduction 3. At the present time, there is no international organization or body responsible for management of seahorses and other syngnathids, including recommendations on catch quotas, gear restrictions, minimum sizes, or temporal and spatial closures of near-shore fishing environments. Significant work is being conducted with some local communities, scientists and industry by Project Seahorse, led by Dr. Amanda Vincent of McGill University, Canada. The United States and Australia believe that discussion of actions that are necessary to collect trade data and determine the impacts of trade on seahorse and other syngnathid populations is essential at this time, in an effort to determine the validity of anecdotal information that populations are being harmed by excessive harvest and trade.

  • First Live Records of the Ruby Seadragon (Phyllopteryx Dewysea, Syngnathidae) Greg W
    Rouse et al. Marine Biodiversity Records (2017) 10:2 DOI 10.1186/s41200-016-0102-x MARINE RECORD Open Access First live records of the ruby seadragon (Phyllopteryx dewysea, Syngnathidae) Greg W. Rouse1* , Josefin Stiller1 and Nerida G. Wilson1,2,3 Abstract Until recently, only two species of seadragon were known, Phycodurus eques (the leafy seadragon) and Phyllopteryx taeniolatus (the common seadragon), both from Australia. In 2015, we described a new species of seadragon, Phyllopteryx dewysea (the ruby seadragon). Although the leafy and common seadragons are well known and commonly seen in aquarium exhibits world-wide, the ruby seadragon was known only from four preserved specimens, leaving many aspects of its biology unknown. Based on specimen records, it was speculated that the ruby seadragon normally lives at depths beyond recreational SCUBA diving limits, which may also explain why it went undiscovered for so long. The rubyseadragonalsobearsasuperficialresemblancetothecommonseadragon,withanumberofspecimens misidentified in museum collections. The only recent live-collected specimen was trawled from the Recherche Archipelago, a cluster of over 100 islands in Western Australia. We took a small remotely operated vehicle (miniROV) to this locality to obtain the first images of live ruby seadragons. We made observations on the seadragon habitat and behavior, including feeding. We also provide new key observations on their morphology, notably that they lack dermal appendages and have a prehensile tail. We recommend that the ruby seadragon be protected as soon as practicable. Keywords: Australia, Biodiversity, Marine, Syngnathid, Seadragon Background (Kuiter 2000). Although the museum specimens of Theoriginaldescriptionoftherubyseadragon(Phyllopteryx ruby seadragons possessed the enlarged bony spines dewysea, Stiller, Wilson and Rouse 2015) was based on four to which these appendages attach in the other spe- specimens, three from near Perth in Western Australia.
