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 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%. -

Mexico's Ten Most Iconic Endangered Species
Alejandro Olivera Center for Biological Diversity, April 2018 Executive summary exico is one of the world’s most biologically rich nations, with diverse landscapes that are home to a treasure trove of wildlife, including plant and animal species found nowhere else. Sadly, in Mexico and Maround the world, species are becoming extinct because of human activities at rates never seen before. In this report we highlight the threats facing Mexico’s 10 most iconic endangered species to help illustrate the broader risks confronting the country’s imperiled plants and animals. These 10 species — which in most cases are protected only on paper — were chosen to reflect Mexico’s diversity of wildlife and ecosystems and the wide range of threats to the country’s biodiversity. New awareness of these unique animals and plants is critical to inspiring a nationwide demand to protect these critical components of Mexico’s natural heritage. Although the Mexican government began officially listing and protecting species as extinct, threatened, endangered, and “under special protection” in 1994 — more than 20 years ago — few species have actually recovered, and many critical threats continue unabated. In many cases, officials are failing to enforce crucial laws and regulations that would protect these species. Additionally, the Mexican government has not updated its official list of imperiled species, referred to as NOM059, since 2010, despite new and growing risks from climate change, habitat destruction, the wildlife trade and in some cases direct killing. This failure obscures the true plight of the nation’s endangered wildlife. The following 10 iconic endangered species are not adequately protected by the Mexican government: 1. -
