Branched ?-1,4-glucan from the gastropod mollusk Strombus gigas

Chemistry of Natural Compounds, 1988
From the mantle of the Caribbean Sea gastropod molluskStrombus gigas a bioglycan containing carbohydrates (73%), protein (22%), and lipid (about 5%) components has been isolated. It has been shown by hydrolysis, periodate oxidation, and methylation that the bioglycan is a D-glucan constructed of α-1,4-bound D-glucose residues and has side chains of D ...

Aspects of the reproductive biology of Strombus gigas

2010
Shell morphology changes relating to sexual maturity and the reproductive cycle of Strombus gigas were studied at a single site within the Barrier Reef lagoon of Belize, Central America. Monthly samples, from July 1981 to June 1983, of transverse tissue sections, through the digestive gland and gonad, were fixed for examination by light microscopy ...

The shell organic matrix of the crossed lamellar queen conch shell (Strombus gigas)

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2014
In molluscs, the shell organic matrix comprises a large set of biomineral-occluded proteins, glycoproteins and polysaccharides that are secreted by the calcifying mantle epithelium, and are supposed to display several functions related to the synthesis of the shell.

Attenuated reproduction of Strombus gigas by an Apicomplexa: Emeriidae-like parasite in the digestive gland

Journal of Invertebrate Pathology, 2012
An intense and generalized sporozoan infection was detected in every population of the queen conch, Strombus gigas through the Caribbean. In this contribution we establish the relationship between occurrences of an Apicomplexa: Emeriidae-like organism and reproductive activity at San Andres archipelago, Colombia.

Occurrence of Apicomplexa-like structures in the digestive gland of Strombus gigas throughout the Caribbean

Journal of Invertebrate Pathology, 2011
The queen conch, Strombus gigas, is a marine resource of ecological and economical importance in the Caribbean region. Given its importance in this region, and the critical status of most populations, the reproductive biology of this species has been studied to support management decisions.

Overview of diets used in larviculture of three Caribbean Conchs: Queen Conch Strombus gigas, Milk Conch Strombus costatus and Fighting Conch Strombus pugilis

Aquaculture, 1998
Abstract The genus Strombus is widely distributed in the Caribbean. Six species are of commercial importance: S. gigas, S. raninus, S. costatus, S. alatus, S. gallus and S. pugilis. Economically, the Queen conch, S. gigas is the most important and consequently the most widely studied. However, since 1970 a decline of S.

Mechanical properties and structure of Strombus gigas, Tridacna gigas, and Haliotis rufescens sea shells: A comparative study

Materials Science and Engineering: C, 2006
Sea shells are composed of calcium carbonate crystals interleaved with layers of viscoelastic proteins, having dense, tailored structures that yield excellent mechanical properties. Shells such as conch (Strombus gigas), giant clam (Tridacna gigas), and red abalone (Haliotis rufescens) have hierarchical architectures that differ depending on growth ...

Growth of the queen conch Strombus gigas, with a discussion of the practicality of its mariculture

Marine Biology, 1976
Data on the growth of the large marine snail Strombus gigas was obtained from specimens collected as veligers in the plankton and reared through metamorphosis, from larger individuals (5.5 cm) reared in a mariculture system, and from field tagrecapture experiments. Using the von Bertalanffy growth equation, I estimate that 1, 2, and 3 year-old juvenile

The Status of Queen Conch, Strombus gigas, Research in the Caribbean

1997
Today there are approximately 230 published scientific papers on queen conch, Strombus gigas. Publication on this species began in the 1960's and increased rapidly during the 1980's and 1990's (Fig. 1). The increase in publication after 1980 was associated with three particular areas ofendeavor. First, many articles were published to document the rapid
