CoP13 Doc. 37.2 CONVENTION ON INTERNATIONAL TRADE IN ENDANGERED SPECIES OF WILD FAUNA AND FLORA ____________________ Thirteenth meeting of the Conference of the Parties Bangkok (Thailand), 2-14 October 2004 Interpretation and implementation of the Convention Species trade and conservation issues Sea cucumbers IMPLEMENTATION OF DECISION 12.60 1. This document has been submitted by Ecuador. Introduction 2. The international trade in sea cucumbers remains a significant conservation issue, and Ecuador has listed one of its native – and heavily exploited – species (Isostichopus fuscus) in Appendix III to control illegal exports and ensure sustainable harvest in the Galapagos Islands. 3. At the 12th meeting of the Conference of the Parties (Santiago, 2002), the United States of America submitted document CoP12 Doc. 45 on the Trade in sea cucumbers in the families Holothuriidae and Stichopodidae. That document described the extensive global trade in various species of sea cucumbers and led to the adoption of Decisions 12.60 and 12.61. 4. Decision 12.61 directs the Secretariat, in part, to the following: b) contingent on the availability of external funding, cooperate with other relevant bodies, including the fisheries sector, to convene a technical workshop to consider and review biological and trade information that would assist in establishing conservation priorities and actions to secure the conservation status of sea cucumbers in these families; and c) contract the preparation of a document for discussion at the technical workshop. This document should contain all relevant available information concerning the status, catches and bycatches of, and trade in specimens of species in the families Holothuriidae and Stichopodidae and on any domestic measures for their conservation and protection, and a review of the adequacy of such measures. -
SPC Beche-De-Mer Infomation Bulletin
SPC Beche-de-mer Information Bulletin #23 – February 2006 39 AbstractsAbstracts && publicationspublications beche-de-merbeche-de-mer SPC translates two chapters of Chantal Conand’s 1989 thesis1:“Aspidochirote holothurians of the New Caledonia lagoon: Biology, ecology and exploitation” SPC's Reef Fisheries Observatory has organised the translation of two chapters of Chantal Conand's semi- nal thesis on the ecology and biology of sea cucumbers. Although this thesis was published in French in 1989, a long time ago, many results were never made available to the wider audience of non-French speak- ers. Since the initial publication of this work, interest on holothurian resources and their management has only increased, and SPC hopes this translation will be of use to fishers, researchers and managers alike. Chantal Conand is now Professor Emeritus at La Reunion University. Her PhD was undertaken at the ORSTOM (now IRD) Center in New Caledonia, and the Laboratory Océanographie Biologique of the University of Bretagne Occidentale in France. She is still involved in sea cucumber research, as the sci- entific editor of this Beche-de-mer Bulletin published by SPC and several programmes of regional and international interest. The translated parts of the PhD thesis are listed below: Part of Chapter two: Ecology of the aspidochirote holothurians 4.

Res., 46(2): 416-423Density, 2018 and population parameters of sea cucumber at Sisal, Yucatan 416 1 DOI: 10.3856/vol46-issue2-fulltext-17 Research Article Density and population parameters of sea cucumber Isostichopus badionotus (Echinodermata: Stichopodidae) at Sisal, Yucatan Alberto de Jesús-Navarrete1, María Nallely May Poot2 & Alejandro Medina-Quej2 1Departamento de Sistemática y Ecología Acuática, Estructura y Función del Bentos El Colegio de la Frontera Sur, Quintana Roo, México 2Instituto Tecnológico de Chetumal, Licenciatura en Biología, Chetumal, Quintana Roo, México Corresponding author: Alberto de Jesús-Navarrete ([email protected]) ABSTRACT. The density and population parameters of the sea cucumber Isostichopus badionotus from Sisal, Yucatan, Mexico were determined during the fishing season. Belt transects of 200 m2 were set in 10 sampling sites at two fishing areas. All organisms within the belt were counted and collected. In the harbor, 7,618 sea cucumbers were measured and weighed: the population parameters were determined using FISAT II. Mean densities of I. badionotus in April 2011, September 2011 and February 2012 were 0.84 ± 0.40, 0.51 ± 0.46, and 0.32 ± 0.17 ind m-2, respectively. Sea cucumber total length varied from 90 to 420 mm, with a uni-modal distribution. The growth parameters were: L∞ = 403 mm, K = 0.25, and to = -0.18, with an allometric growth (W = 2.81L1.781). The total mortality was 0.88, whereas natural mortality was 0.38, fish mortality was 0.50 and the exploitation rate 0.54. Even when sea cucumbers fishery in Sisal is recent and in development with a high density (5570 ind ha-1), it is necessary to establish management strategies to protect the resource, such as an annual catch quota, catching size (>280 mm length), monitoring of population density, and reproduction and larval distribution. -
Wildlife and Ecosystems the Ecuador Project Winter 2017 January 18 – March 3
WILDLIFE AND ECOSYSTEMS THE ECUADOR PROJECT WINTER 2017 JANUARY 18 – MARCH 3 ACADEMIC SYLLABUS Lead instructor: Geoff Gallice, Ph.D. Office hours: We will all be in close contact, meeting every day throughout the course. There will be a number of ‘check-in days’ where we will schedule student-instructor meetings. If you would like to have a meeting outside of those times, you can certainly make an appointment, or find an appropriate available time, and I am happy to oblige. Class meetings: The Wildlands Studies Ecuador Project involves seven days per week of instruction and field research during the program. Faculty and staff work directly with students 6-10+ hours a day and are available for tutorials and coursework discussion before and after scheduled activities. Scheduled activities each day begin as early as 6 am, with breaks for meals. Most evenings include scheduled activities, as well as reading discussions, guest lectures, structured study time, and night time field activities. When in the backcountry or at a field site, our activities may start as early as 4 am or end as late as 10 pm (e.g., for wildlife observation). It is necessary to be flexible and able to accommodate a variety of class and activity times. Course credit: Wildlands Studies Project students receive credit for three undergraduate courses. These three courses have distinct objectives and descriptions, and we integrate teaching and learning through both formal learning situations (i.e., lectures and seminars) and field surveys. Academic credit is provided by Western Washington University. Extended descriptions follow in the course description section of this syllabus. -
Tuna Be, Or Not Tuna Be: Using Catch Data to Observe the Ecological Impacts of Commercial Tuna Fisheries in the Pacific Ocean at Varying Spatial Scales
TUNA BE, OR NOT TUNA BE: USING CATCH DATA TO OBSERVE THE ECOLOGICAL IMPACTS OF COMMERCIAL TUNA FISHERIES IN THE PACIFIC OCEAN AT VARYING SPATIAL SCALES by Laurenne Louise Schiller B.Sc. (Hons.), University of Guelph, 2010 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE in The Faculty of Graduate and Postdoctoral Studies (Zoology) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) August 2014 © Laurenne Louise Schiller, 2014 ABSTRACT Tuna are arguably the world’s most valuable, versatile, yet vulnerable fishes. With current landings over 4 million tonnes annually, all species of tuna from all three major ocean basins are caught, traded, and consumed at various intensities around the globe. Understanding the implications of such an extensive industry is paramount to protecting the long-term health and sustainability of both the tuna fisheries as well as the ecosystems in which they operate. Given that the Pacific Ocean accounts for roughly two-thirds of the global commercial tuna catch, this thesis assesses the trends and ecological impacts of commercial tuna fishing at both the artisanal and industrial scale in this ocean. To observe the importance of tuna fisheries at a local scale, a case study of the Galápagos Islands is presented. In this context, it was observed that over-fishing and the subsequent depletion of large, low fecund serranids has resulted in a high level of ‘fishing down’ within the near- shore ecosystem. Consequently, as fishers are forced to expand to regions off-shore, tuna and coastal scombrids are becoming increasingly targeted. With regard to industrial fishing, tuna vessels (especially distant-water longliners) are known to generate a substantial amount of associated bycatch and discards. -

Population status, fisheries and trade of sea cucumbers in Latin America and the Caribbean. In V. Toral-Granda, A. Lovatelli and M. Vasconcellos (eds). Sea cucumbers. A global review of fisheries and trade. FAO Fisheries and Aquaculture Technical Paper. No. 516. Rome, FAO. 2008. pp. 213–229. SUMMARY The region under study comprises a total of 25 countries where, although there are some sea cucumber fisheries, scant information exists about them. There are eleven species of sea cucumbers currently harvested for commercial use in the region, with legal and illegal fisheries currently occurring in Mexico, Panama, Colombia, Ecuador, Nicaragua, Peru, Venezuela and Chile. In most of the countries where a fishery exists, there is hardly any biological or ecological information as well as little knowledge on the population status and even, in some cases, the taxonomy of the species under commercial exploitation. In most countries with ongoing fisheries, no management measures are in place and new species are normally being incorporated to the fishing activities. Although sea cucumber fishing it is not a traditional activity, some households have become highly dependent on this fishery, with increasing pressure towards decision makers to allow such activity. -

Abstract: The brown sea cucumber fishery is active in the Galapagos Islands since the year 1991 after its col- lapse in mainland Ecuador. This paper analyzes the Galapagos Sea cucumber fishery over the past decade and the reasons for its management pitfalls and chronic over fishing, and proposes an improved strategy for estimating stock size and harvest potential. Based on the historical distribution of the fishing fleet and past fishery surveys, 15 macrozones were defined; their areas were estimated from the coastline to the 30m isobaths and the numbers of sample replicates per macrozone were calculated for a density estimate precision of ±25%. -

Contamination by Cruise Ships
CONTAMINATION BY CRUISE SHIPS June 2004 CONTAMINATION BY CRUISE SHIPS Introduction Cruise ship tourism has experienced massive growth in the last thirty years. During these three decades, the number of people opting to spend their vacation on board one of these vessels has multiplied by 25 and so, as a result, have any associated problems. More than 50 companies control almost 300 cruise ships that carry millions of passengers from one point of the planet to another. Some of the most popular tourist destinations are those which, at the same time, are the most sensitive to environmental disturbance. The Caribbean, Alaska, the Mediterranean, the Nordic fiords and the coasts of many small islands are subjected to visits from these giant vessels. Their natural beauty is the attraction, but also their Achilles heel, as these spots are very vulnerable. Big cruise liners can carry up to 5,000 people, including a crew of more than 1,000, which makes them genuine floating cities. With lengths that exceed 300 metres and gross tonnage of more than 100,000 GRT, onboard facilities include swimming pools, theatres, cinemas, restaurants, shops, saunas, tennis courts, photo processing shops, laundries, dry cleaning and everything a passenger could possibly require during his stay in his floating hotel. But all these activities generate hundreds of tons of waste of every kind, part of which is thrown into the seas and oceans plied by these ships. International legislation on the processing and dumping of this waste barely regulates the activities of cruise ships, so tonnes of waste end up in the ocean waters, having hardly been treated.
