Reports
Fluorescent bulbs are widely used for algal culture stocks and production in aquaculture operations. Metal halide lamps are also used for production tanks with significant electricity demand and heat production. LED technology promises lower operational costs with less energy waste as heat for equivalent light energy production. Re-tooling algal production facilities with new LED fixtures incurs significant expense that must be recaptured in savings over time. The initial cost, added to concerns over the unknown response of algae to LED light sources may both be factors inhibiting incorporation of this new technology. LED replacement tubes are available to retrofit fluorescent …

The identification of bivalve larvae and early postlarvae in plankton and benthic samples has long been a challenge, hampering both basic and applied research efforts in marine, estuarine, and freshwater environments. The usefulness of published optical micrographs of the early life-history stages of bivalves is limited because of the great morphological similarity of the imaged articulated shells, particularly at the early (straight-hinge) developmental stages. While a number of techniques have been refined in recent years and show promise for use in routine identifications of larval and post-larval bivalves (e.g., single-step nested multiplex polymerase chain reaction; in situ hybridization protocols through …
