Biological weighting of ultraviolet (280–400 nm) induced mortality in marine zooplankton and fish. I. Atlantic cod (Gadus morhua) eggs
Abstract In the Gulf of St. Lawrence, Canada, productivity-determining biophysical interactions occur in the upper 0 to 30 m of the water column. The eggs and larvae of several commercially importantExpand

Perspectives on ecosystem-based approaches to the management of marine resources
Marine Protected Areas (MPAs) include many subclasses (e.g. marine sanctuaries, marine parks, wildlife refuges, fisheries closures, no-take MPAs, multiple-use MPAs, marine reserves, ecologicalExpand

Penetration of ultraviolet radiation in the waters of the estuary and Gulf of St. Lawrence
Downwelling ultraviolet (UV) irradiance (290-400) nm was measured at 1-nm intervals in the surface waters of the estuary and Gulf of St. Lawrence, Canada, in September 1996 and June and SeptemberExpand

Wrasse (Labridae) as cleaner fish in salmonid aquaculture – The Hardangerfjord as a case study
Abstract Several species of wrasse (Labridae) are used as cleaner fish to remove salmon lice from farmed Atlantic salmon. We estimated the fishery and use of wrasse in Hardangerfjord. The estimatedExpand

Impact of ultraviolet radiation on marine crustacean zooplankton and ichthyoplankton: a synthesis of results from the estuary and Gulf of St. Lawrence, Canada
The objectives of the research program reported upon here were (1) to measure ambient levels of UV radiation and determine whichvariables most strongly affected its attenuation in the waters of theExpand

Effect of solar ultraviolet radiation (280–400 nm) on the eggs and larvae of Atlantic cod (Gadus morhua)
Dans le golfe du Saint-Laurent (Canada), le rayonnement solaire ultraviolet B (UV-B, 280-320 nm) penetre une partie importante de la couche de melange estivale. Les organismes presents dans cetteExpand

Thyroxine induces a precocial loss of ultraviolet photo sensitivity in rainbow trout (Oncorhynchus mykiss, teleostei)
Small (< 30 g) juvenile rainbow trout (Oncorhynchus mykiss) possess retinal photoreceptor mechanisms sensitive to ultraviolet (UV), short (S), middle (M) and long (L) wavelengths. During normalExpand

Correlation between histological and behavioral measures of visual acuity in a zooplanktivorous fish, the white crappie (Pomoxis annularis).
Estimates of visual acuity in a pelagic freshwater zooplanktivorous fish, the white crappie (Pomoxis annularis, Centrarchidae), were made using a behavioral measure, the maximum observed prey pursuitExpand

Exposure to increased ambient ultraviolet B radiation has negative effects on growth, condition and immune function of juvenile Atlantic salmon (Salmo salar).
Atlantic salmon (Salmo salar) parr were exposed in two outdoor experiments, ranging in duration from 52 to 137 days, to spectral treatments: (1) natural sunlight (=present ambient UVB level), (2)Expand

Applying organized scepticism to ocean acidification research
“Ocean acidification” (OA), a change in seawater chemistry driven by increased uptake of atmospheric CO2 by the oceans, has probably been the most-studied single topic in marine science in recentExpand
