Co-occurrence of viral and bacterial pathogens in disease outbreaks affecting newly cultured sparid fish.
Several microbial disease outbreaks in farm stocks of newly cultured sparid fish species, such as common seabream, redbanded seabream, and white seabream, were recorded from 2004 to 2006. This study describes the isolation and characterization of the potential causative agents, either bacteria or viruses, of these outbreaks. The isolated bacterial strains were characterized according to traditi...
متن کاملHalfway up the trophic chain: development of parasite communities in the sparid fish Boops boops.
We examined the patterns of composition and structure of parasite communities in the Mediterranean sparid fish Boops boops along a gradient of fish sizes, using a large sample from a single population. We tested the hypothesis that species forming the core of the bogue parasite fauna (i.e. species which have a wide geographical range and are responsible for recognizable community structure) app...
متن کاملAge and growth of the estuarine-dependent sparid Acanthopagrus berda in northern KwaZulu-Natal, South Africa
INTRODUCTION The riverbream or perch, Acanthopagrus berda (family Sparidae), is widespread in the tropical Indo-Pacific region, occurring from South Africa to India, northern Australia and Japan (Smith & Heemstra 1986; Garratt 1993). In South Africa it is found along the east coast, where its range extends southwards to Port Elizabeth (33°58’S, 25°36’E). It is one of 22 species of fishes found ...
متن کاملCross-Validation Estimates IMSE
Integrated Mean Squared Error (IMSE) is a version of the usual mean squared error criterion, averaged over all possible training sets of a given size. If it could be observed, it could be used to determine optimal network complexity or optimal data subsets for efficient training. We show that two common methods of cross-validating average squared error deliver unbiased estimates of IMSE, conver...
