Le stock de Lambi (Strombus gigas, L.) en Martinique : analyse de la situation 1986-1987, modélisation de l'exploitation, options d'aménagement ArchiMer
Rathier, I.
The stock of Lambi, Strombus gigas (gastropod: strombidae), coastal benthic resource, has been exploited artisanally since the prehistoric period in Martinique. Nowadays, three lines of work exploit the species: free diving, nets (since the middle of the century) and scuba diving since 1985. This report presents the activity of each line of work, surveyed directly from 1986 to 1987: fishing zones and resource allocation, production, effort and performance, detail of catches (by length). The socio economic characteristics of the lambi fishermen are studied. The significant production of leisure fishing is also estimated. The decrease in the production and performance, as well as the lowering of the size of the first catch for about thirty years show that...

IDENTIFICACIÓN MOLECULAR DE POBLACIONES BACTERIANAS ASOCIADAS AL CARACOL PALA (Strombus gigas) DEL CARIBE COLOMBIANO Acta biol.Colomb.
ACOSTA,EDINSON ANDRÉS; GÓMEZ,ELIANA; ROMERO TABAREZ,MAGALLY; CADAVID RESTREPO,GLORIA ESTER; MORENO HERRERA,CLAUDIA XIMENA.
El caracol Pala, Strombus gigas (Strombidae), es de gran importancia ecológica y socioeconómica en el área caribeña colombiana. Sin embargo, es una especie catalogada como "vulnerable" y existe muy poca información referente a las especies bacterianas asociadas al caracol que puedan ser importantes para el desarrollo, manejo productivo y de seguridad acuícola de estos gastrópodos. En este trabajo, nosotros empleamos un estudio microbiológico y molecular de la región intergénica entre los genes 16S y 23S rDNA, análisis del gen rDNA 16S y secuenciación, para analizar las bacterias asociadas al caracol Pala (S. gigas). La composición de bacterias cultivables asociadas fue evaluada por su capacidad para crecer en agar marino y en medios de cultivos selectivos....

SIZE AT SEXUAL MATURITY IN THE QUEEN CONCH STROMBUS GIGAS FROM COLOMBIA Boletín de Investigaciones
Avila-Poveda,Omar Hernando; Baqueiro-Cárdenas,Erick Raúl.
Size at sexual maturity was investigated in 346 queen conch, Strombus gigas, collected from the Archipelago of San Andres, Providencia and Santa Catalina (SAI), Colombia. Size at sexual maturity is defined as the size (based on total shell length and lip thickness) at which 50% of the population of queen conch sampled had mature and emission gonad developmental stages, based on microscopic examination (samples of gonads were processed by standardized histological methods). Only 12.14% of whole samples had mature and emission gonad developmental stages. The size at sexual maturity based on total shell length (STmat) was estimated to be STmat=249 mm for females (n=14), STmat=234 mm for males (n=28) and STmat=241 mm for both sexes (n=42). Lip thickness...
