  • Studies of Age and Growth of the Gastropod Turbo Marmoratus Determined from Daily Ring Density B
    i I Proc 8th Int Coral Reef Sym 2:1351-1356. 1997 STUDIES OF AGE AND GROWTH OF THE GASTROPOD TURBO MARMORATUS DETERMINED FROM DAILY RING DENSITY B. Bourgeois1, C.E. Payril and P. Bach2 1 Laboratoire d'Ecologie Marine, Universite Française du Pacifique, BP 6570 FaaalAéroport, Tahiti, French Polynesia * ORSTOM, BP 529, Papeete, Tahiti, French Polynesia . ABSTRACT This is a study of the age and growth of the gastropod Turbo marmoratus using a sclerochronological method. The shells of an introduced population on Tahiti (pench Polynesia) are examined. The confirmation of age, based on a novel marking technique using a lead pencil, xgveals a daily rate of deposition within the growth rings..*:A new method of estimation of the growth parameters of the Von Bertalanffy model from the daily ring density (DRD) is described. The fit to the model allows the estimation of K = 0.32 year': and D, = 30.3 cm (D = diameter). INTRODUCTION The green snail, Turbo marmoratus, was introduced in w w Tahiti (French Polynesia) waters in 1967. It has thrived 15òo 14i" in the Polynesian archipelago, constituting a new 1 I resource whose stocks are exploited without particular knowledge of its biology. It has a current natural western Indo-Pacific distribution. A renewed interest in natural products has made it a luxury item, whose price has not ceased to rise over the last decade, while the world-wide stock is decreasing (Yamaguchi 1988a, 1991). Despite the economic value of this species, no growth studies have been undertaken in natura. To our knowledge, only the works of Yamaguchi (198823) deal with the biology and the ecology of Turbo marmoratus, and are based on observations in pools and aquaria in sub-tropical conditions.

Belgium. SUMMARY: The gastropod family Hipponicidae comprises widely distributed but poorly known sedentary species. On the beach-rock of the coral reefs of Laing Island (Papua New Guinea) live rich populations of several gastropod Turbo species of which many specimens have attached to their shell a hipponicid gastropod attributed to a new species, Antisabia juliae. This new species, described in this paper, appears to have adapted its mode of life on live turbinids in several ways result- ing in morphological changes (thin basal plate loosely adherent to the supporting shell, functional eyes, very long snout, functional radula, small osphradium) and ethological changes (foraging behaviour: it appears to feed on the epiphytic com- munity growing on the host, in the vicinity of the “host” shell). Except for these characteristics, the mode of life appears quite similar to that of other hipponicid species with few big females surrounded by several much smaller males. Development occurs within the egg mass inside the female shell and a few young snails escape at the crawling stage. Key words: Mollusca, Gastropoda, ecology, Hipponicidae, Papua New Guinea, Indopacific. RESUMEN: BIOLOGÍA Y DESCRIPCIÓN DE ANTISABIA JULIAE SP.

For this purpose, the material collected from the area between the years 2005 and 2009, within the framework of different projects, was investigated. The investigation of the material taken from various biotopes ranging at depths between 0 and 100 m resulted in identification of 286 mollusc species and 27542 specimens belonging to them. Among the encountered species, Vitreolina cf. perminima (Jeffreys, 1883) is new record for the Turkish molluscan fauna and 18 species are being new records for the Turkish Levantine coast. A checklist of Iskenderun mollusc fauna is given based on the present study and the studies carried out beforehand, and a total of 424 moluscan species are known to be distributed in Iskenderun Bay.
