摘要:Abstract(#br)In recent years, black-spot shell disease has appeared on the shells of Akoya pearl oysters, Pinctada fucata , causing serious problems in cultured pearl production. This disease was believed to be caused by boring of Polydora ciliata into calcareous substrate, and a...

摘要:... Recently, observations of black-spot syndrome (BSS) in Caribbean fishes, especially ocean surgeonfishes, Acanthurus tractus (Poey, 1860), have been reported, although its cause(s) has remained conjectural. We investigated the etiology of BSS and whether the pathology was...

摘要:... We performed laboratory experiments to investigate whether acclimation to shelters affects the post-release survival of hatchery-reared black-spot tuskfish Choerodon schoenleinii in the presence of a reef-resident predator, the white-streaked grouper Epinephelus ongus . Tuskf...

摘要:... Total lengths and numbers of externally-visible black-spot cysts were recorded for infected fish. Mean cyst densities, variance-to-mean ratios, and prevalence rates were consistently higher in Blackburn Fork than in Spring Creek. Peaks in prevalence and variance-to-mean ratio...

摘要:... The resulting black-spot damage was examined by electron microscopy. From stereomicrographs of foils decorated on one surface it was possible to measure the distance of certain defects from that surface. The direction of black-white streaking of the same defects was observe...

摘要:Abstract(#br)In this study, the effect of shelter acclimation on the post-release movement and putative predation mortality of hatchery-reared black-spot tuskfish Choerodon schoenleinii was examined using acoustic telemetry. We acclimated four 1-year-old fish to shelters in cages...

摘要:O objetivo deste trabalho foi avaliar a resistência de Guignardia citricarpa aos fungicidas carbendazim e piraclostrobina, por meio de avaliação do crescimento em meio de cultura, decomposição de tecido foliar e produção de corpos de frutificação. Para isso, o fungo G. ...

摘要:Abstract(#br)At the end of July 2004, a “black-spot” appeared in the western portion of Lake Garda, an oligomictic lake classified as meso-oligotrophic. A few days later, this phenomenon spread throughout the lake. A first analysis by optical microscopy revealed that the...
