Non‒visualisations of the fetal bladder: aetiology and management

Failure to detect a normally filled fetal bladder on ultrasound scanning can imply the presence of a serious urogenital abnormality. Detailed scanning may elicit the underlying pathology, but there may be complex anomalies present, the full extent of which often has to await the results of postnatal investigations. Management in a combined paediatric urology:fetal medicine clinic is recommended. Copyright © 2001 John Wiley & Sons, Ltd.     

Toward a sustainable Iceland scallop fishery in Gilbert Bay,a marine protected area in the eastern Canada coastal zone

Iceland scallop (Chlamys islandica) stocks in the North Atlantic are usually pulse harvested, resulting in boom and bust local landings. We describe an adaptive management strategy for a sustainable harvest of Iceland scallops in Gilbert Bay, a Marine Protected Area (MPA) of coastal Labrador. The current management plan for the MPA closes pristine scallop habitat, a practice that under favourable ocean conditions may lead to local reseeding. The community-based co-management structure for the MPA utilizes the local ecological knowledge of fishermen. Scallop harvesters are participating in research on the present state of the resource. Currently scallops are smaller near the mouth of the bay where fishing effort has been concentrated historically. The cooperation of fishers in enforcing area closures and in monitoring the scallop harvest may lead to a sustainable scallop fishery.
