Catenovulum sp. strain DS-2, isolated from intestines of Haliotis diversicolor, is able to degrade agar and produce agaro-oligosaccharides. Here, we report the draft genome sequence of Catenovulum sp. strain DS-2.

Using a probabilistic risk-based framework, we have developed a simple predictive risk threshold model for protecting the survival of farmed abalone, Haliotis diversicolor supertexta, exposed to waterborne zinc (Zn). Probabilistic techniques using Monte Carlo analysis propagate parameter uncertainty/variability throughout the model, providing decision makers with a credible range of information...

Toxicity of the extracellular products (ECP) and the lethal attribute of serine protease secreted by five pathogenic Vibrio alginolyticus strains from various sources in kuruma prawn Penaeus japonicus were studied. The ECPs of organisms originally isolated from diseased kuruma prawn or small abalone Haliotis diversicolor supertexta were more lethal (LD50 value of 0.48 or 0.41 microg protein/g p...

The lethal concentration for 50% of aquacultural animals (LC50)-based tests determines the external effect concentration (EEC) following certain statistical models, revealing that no biologically based mechanistic information and only statistical interpretations of its model parameters could be made. The purpose of this paper is to determine the survival risk of waterborne metals toward farmed ...

Taiwan abalones, Haliotis diversicolor supertexta, held in 30 parts/per thousand seawater at 28 degrees C, were injected with TSB-grown Vibrio parahaemolyticus (1.6x10(5) cfu abalone(-1)) and then transferred to 20, 24, 28 and 32 degrees C. All abalones transferred to 32 degrees C died by 72 h. The mortality of V. parahaemolyticus-injected abalone held at 20 and 24 degrees C was significantly l...

The analysis of expressed sequence tags (ESTs) is an efficient approach for gene discovery, expression profiling, and the development of resources for functional genomics. To analyze the transcriptome response to tributyltin of small abalone Haliotis diversicolor supertexta, a normalized cDNA library of hepatopancreas after exposure of animals to tributyltin was constructed. Three thousand and ...

This investigation analyzed the Zn-bioaccumulation kinetics in the abalone Haliotis diÕersicolor supertexta and in the red alga Gracilaria tenuistipitata var. liui for assessing bioconcentration and biomagnification in an aquacultural system. Laboratory exposure experiments estimated Ž . uptake and depuration rate constants i.e., k and k , respectively of H. diÕersicolor supertexta 1 2 Ž . via ...
