[email protected] [email protected] Abstract Echinoderms, exclusively marine animals, present a great diversity and are an important and very ancient phylum. Whether they are predators, vegetarian or scavengers, echinoderms frequently dominate the ecosystems in which they are subservient. Benthic macrofauna and particularly echinoderms acting directly on the functioning of marine ecosystems, represents the fundamental link in the food chain and an essential source of food for many consumers. There has been very little work on the echinoderms found in the western Algerian coast. The objective of this work is to conduct an inventory on the echinological fauna in the intertidal zone, including the description of the morphological and ethoecological characteristics of the echinoderms in their ecosystem. To this end ten stations were surveyed. For each station, a random sampling was performed on hard substrates found in the coast of Oran. The identification of species and faunal analysis permitted to identify six species belonging to this phylum with a presence of 55.17% of Echinoids (Echinoids), 34.8% of sea cucumber (holothurian) and 10.34% of starfish (Asteroidean). Keywords: echinoderms; benthic macrofauna; Macro-invertebrates; marine ecosystems; Coast of Oran; West of Algeria. -

Development of Techniques for Gender Identification in Holothuria Forskali
SPC Beche-de-mer Information Bulletin #37 – March 2017 95 Development of techniques for gender identification in Holothuria forskali (Delle Chiaje, 1823) Daniela Pratas,1* Filipa Santos,1 Simaura Dias,1 Vânia Rodrigues,1 Marina Couto,1 Rita Santos,1, 2 Teresa Baptista1 and Ana Pombo1 Abstract Holothuria forskali is a widely distributed sea cucumber species in the Atlantic Ocean and Mediterranean. Understanding the reproductive biology study of H. forskali is a crucial step towards achieving the sustain- able production of this species in aquaculture facilities. Because echinoderms have no sexual dimorphism, it is not possible to determine their gender externally. This study aims to apply four different techniques for determining the gender of holothurians through the collection of a piece of gonad: biopsy, aspiration without incision, a short incision in the dorsal side, and a short cut in the anterior part. The biopsy method showed the highest percentage of accuracy, with 100% of gender identification compared with the other methods. In the two methods with incision, specimens were fully recovered after 21 days, showing no signs of scars or any evidence of the cut made. Introduction of a piece of gonad using a biopsy needle, aspi- ration of the gonad blunt, cutting the dorsal part Echinoderms show no sexual dimorphism, so with suction, and cutting the anterior part.

Community Structure, Diversity, and Distribution Patterns of Sea Cucumber
Community structure, diversity, and distribution patterns of sea cucumber (Holothuroidea) in the coral reef area of Sapeken Islands, Sumenep Regency, Indonesia 1Abdulkadir Rahardjanto, 2Husamah, 2Samsun Hadi, 1Ainur Rofieq, 2Poncojari Wahyono 1 Biology Education, Postgraduate Directorate, Universitas Muhammadiyah Malang, Malang, East Java, Indonesia; 2 Biology Education, Faculty of Teacher Training and Education, Universitas Muhammadiyah Malang, Malang, Indonesia. Corresponding author: A. Rahardjanto, [email protected] Abstract. Sea cucumbers (Holothuroidea) are one of the high value marine products, with populations under very critical condition due to over exploitation. Data and information related to the condition of sea cucumber communities, especially in remote islands, like the Sapeken Islands, Sumenep Regency, East Java, Indonesia, is still very limited. This study aimed to determine the species, community structure (density, frequency, and important value index), species diversity index, and distribution patterns of sea cucumbers found in the reef area of Sapeken Islands, using a quantitative descriptive study. This research was conducted in low tide during the day using the quadratic transect method. Data was collected by making direct observations of the population under investigation. The results showed that sea cucumbers belonged to 11 species, from 2 orders: Aspidochirotida, with the species Holothuria hilla, Holothuria fuscopunctata, Holothuria impatiens, Holothuria leucospilota, Holothuria scabra, Stichopus horrens, Stichopus variegates, Actinopyga lecanora, and Actinopyga mauritiana and order Apodida, with the species Synapta maculata and Euapta godeffroyi. The density ranged from 0.162 to 1.37 ind m-2, and the relative density was between 0.035 and 0.292 ind m-2. The highest density was found for H. hilla and the lowest for S. -
The Marine Fauna of Lundy Ecidnodermata
Rep. Lundy Fld Soc. 29 (1978) THE MARINE FAUNA OF LUNDY ECIDNODERMATA P. A. TYLER Department of Oceanography, University College, Swansea, S. Wales, U.K. INTRODUCTION The five classes of echinoderms are a conspicuous element of the fauna in truly marine areas. The British echinoderm fauna has been treated in detail by Mortensen (1927). In shelf sea areas they are usually found below LWN tide level with occasional species moving up into the littoral zone. Examples of the dominant extant groups are found in all types of substrates, the ophiuroids and the heart urchins being particularly important in the determination of soft substrate benthic communities (Thorson, 1947). SOURCES OF MATERIAL The collections made by divers during marine surveys of Lundy have pro duced a considerable record particularly of the conspicuous epifaunal asteroids, regular echinoids and holothurians. Observations of the less conspicuous in faunal ophiuroids and irregular echinoids have been obtained by divers and by benthic surveys using R.V. 'Ocean Crest'. THE LUNDY FAUNA- GENERAL CONSIDERATIONS To date, 24 species of echinoderm have been recorded around Lundy. Of these species only 8 were recorded by Harvey (1950, 1951) at Lundy. The most noteable exceptions to the fauna are Acrocnida brachiata and Spatangus purpureus, both of which have been found further up the Bristol Channel and may be supposed to be found round Lundy where a suitable substrate exists for these infaunal species. A number of species appear to be common all round the island. These include Asterias rubens, Marthasterias glacia/is, Luidia ciliaris, Echinus esculentus and Holothuria forskali. The very rare sea cucumber Lepto synapta decaria has been reported as occurring round Lundy (Hoare & Wilson, 1976). -

Received: 3 August 2011; in revised form: 30 August 2011 / Accepted: 8 September 2011 / Published: 10 October 2011 Abstract: Sea cucumbers, belonging to the class Holothuroidea, are marine invertebrates, habitually found in the benthic areas and deep seas across the world. They have high commercial value coupled with increasing global production and trade. Sea cucumbers, informally named as bêche-de-mer, or gamat, have long been used for food and folk medicine in the communities of Asia and Middle East. Nutritionally, sea cucumbers have an impressive profile of valuable nutrients such as Vitamin A, Vitamin B1 (thiamine), Vitamin B2 (riboflavin), Vitamin B3 (niacin), and minerals, especially calcium, magnesium, iron and zinc. A number of unique biological and pharmacological activities including anti-angiogenic, anticancer, anticoagulant, anti-hypertension, anti-inflammatory, antimicrobial, antioxidant, antithrombotic, antitumor and wound healing have been ascribed to various species of sea cucumbers. Therapeutic properties and medicinal benefits of sea cucumbers can be linked to the presence of a wide array of bioactives especially triterpene glycosides (saponins), chondroitin sulfates, glycosaminoglycan (GAGs), sulfated polysaccharides, sterols (glycosides and sulfates), phenolics, cerberosides, lectins, peptides, glycoprotein, glycosphingolipids and essential fatty acids. -

Reproductive Biology of the Sea Cucumber Holothuria Sanctori (Echinodermata: Holothuroidea)
SCIENTIA MARINA 76(4) December 2012, 741-752, Barcelona (Spain) ISSN: 0214-8358 doi: 10.3989/scimar.03543.15B Reproductive biology of the sea cucumber Holothuria sanctori (Echinodermata: Holothuroidea) PABLO G. NAVARRO 1,2, SARA GARCÍA-SANZ 2 and FERNANDO TUYA2 1 Instituto Canario de Ciencias Marinas, Ctra. Taliarte s/n, Telde, 35200, Las Palmas, Spain. E-mail: [email protected] 2 BIOGES, Universidad de Las Palmas de Gran Canaria, 35017, Las Palmas de G.C., Spain. SUMMARY: The reproductive biology of the sea cucumber Holothuria sanctori was studied over 24 months (February 2009 to January 2011) at Gran Canaria through the gonad index and a combination of macro- and microscopic analysis of the gonads. Holothuria sanctori showed a 1:1 sex ratio and a seasonal reproductive cycle with a summer spawning: the mean gonad index showed a maximum (3.99±0.02) in summer (June-July) and a minimum (0.05±0.04) between late autumn (November) and early spring (March). Females had significantly wider gonad tubules than males. First maturity occurred at a size of 201 to 210 mm, a gutted body weight of 101 to 110 g and a total weight of 176 to 200 g. Holothuria sanctori shows a typical temperate species reproduction pattern. These results could be useful for managing current extractions of H. sanctori in the Mediterranean and in case a specific fishery is started in the eastern Atlantic region. Keywords: Holothuria sanctori, sea cucumber, holothurians, reproduction, life-cycle, maturity, Canary Islands.
