Dietary and nondietary accumulation of waterborne zinc (Zn) by shell of abalone Haliotis diversicolor supertexta was studied to determine if abalone shell can accumulate and eliminate Zn biokinetically. Shell of H. diversicolor supertexta rapidly accumulated Zn at microgram per gram concentrations during a 7-d uptake period for dietary and nondietary exposure to 1 microgml(-1) Zn seawater. Depu...

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...

Prospective elasticity analyses have been used to aid in the management of fished species and the conservation of endangered species. Elasticities were examined for deterministic size-based matrix models of red abalone, Haliotis rufescens, and white abalone, H. sorenseni, to evaluate which size classes influenced population growth (lambda) the most. In the red abalone matrix, growth transitions...

On Australian aquaculture farms, early life stages of abalone are reared under controlled abiotic and biotic conditions in an attempt to optimize individual growth and reduce potential stressors. Yet, physiological responses to the rearing conditions are largely unknown. This study tests if commercial stocking densities, light conditions, and oxygen levels influence the oxygen consumption rate ...

Over the past three decades, the black abalone, Haliotis cracherodii, has experienced precipitous declines in abundance over portions of its range in southern and central California. The potential for recovery of these populations is dependent in part on dispersal processes; that is, can distant populations serve as sources of recruits to locales that no longer harbor H. cracherodii? Here we us...

The study was carried out between the years 2019-2020 in order to determine Chrysomelidae species and their host plants vegetable fields of greenhouses, gardens, open located central district Burdur province. As a result 366 samples examined; 18 belonging 5 genera from Galerucinae subfamily, 2 Chrysomelinae 1 Criocerinae subfamily were identified. Information about local distributions added for...

Assessing patterns of fisheries activity at a scale related to resource exploitation has received particular attention in recent times. However, acquiring data about the distribution and spatiotemporal allocation of catch and fishing effort in small scale benthic fisheries remains challenging. Here, we used GIS-based spatio-statistical models to investigate the footprint of commercial diving ev...

Flammeovirga sp. SJP92 is a Gram-negative, aerobic, rod-shaped, non-motile and non-flagellated strain that belongs to the family Flammeovirgaceae of the class Cytophagia. The strain was isolated from the intestine of abalone, which produces many extracellular agarases and exhibits efficient degradation activities on various polysaccharides, especially agarose. Here we present the high-quality d...
