Genetic diversity and stock identification of small abalone (Haliotis diversicolor) in Taiwan and Japan
Small abalone (Haliotis diversicolor) is a commercially valuable species for both fisheries and aquaculture. The production of annual farmed small abalone in Taiwan, once the highest in the world, has dramatically decreased in the past 15 years, and currently, the industry is close to collapse. Understanding the genetic diversity of small abalone and developing stock identification methods will...
متن کاملLow genetic diversity and genetic differentiation among domesticated stocks of the small abalone Haliotis diversicolor in China
AFLP markers were used to investigate levels of genetic diversity within cultured populations of the small abalone Haliotis diversicolor in China and to compare them with a wild population. A total of 234 fragments, with a size range of 150-500 bp, were identified from 152 individuals by five AFLP primer combinations. High proportion of polymorphic loci (77.65%) and heterozygosity (0.2124) were...

in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Identification and characterization of Vibrio harveyi associated with diseased abalone Haliotis diversicolor.
Mass mortality of farmed small abalone Haliotis diversicolor occurred in Fujian, China, from 2009 to 2011. Among isolates obtained from moribund abalones, the dominant species AP37 exhibited the strongest virulence. After immersion challenge with 106 CFU ml-1 of AP37, abalone mortalities of 0, 53 and 67% were induced at water temperatures of 20°C, 24°C, and 28°C, respectively. Following intramu...
متن کاملInvolvement of Antizyme Characterized from the Small Abalone Haliotis diversicolor in Gonadal Development.
The small abalone Haliotis diversicolor is an economically important mollusk that is widely cultivated in Southern China. Gonad precocity may affect the aquaculture of small abalone. Polyamines, which are small cationic molecules essential for cellular proliferation, may affect gonadal development. Ornithine decarboxylase (ODC) and antizyme (AZ) are essential elements of a feedback circuit that...
