Graham, I.M., Harris, R.N., Denny, B., Fowden, D., and Pullan, D. ICES Journal of Marine Science [email protected] Trials of acoustic deterrent devices (ADD) were carried out on the River North Esk and River Conon in Scotland to test the effectiveness of deterring seals from a specific area of the river and as a barrier to […]
Fecal glucocorticoids and anthropogenic injury and mortality in North Atlantic right whales Eubalaena glaciallis | Consortium for Wildlife Bycatch Reduction
Rolland, R.M., McLellan, W.A., Moore, M.J., Harms, C.A., Burgess, E.A. and K. Hunt Marine Ecology Progress Series Anderson Cabot Center for Ocean Life, New England Aquarium, Central Wharf, Boston, MA 02110, USA [email protected] The fecal glucocorticoid metabolites (fGC) concentrations from right whales (Eubalaena glacialis) chronically entangled in fishing gears or live stranded were compared to […]
Hydrodredge: Reducing the negative impacts of scallop dredging | Consortium for Wildlife Bycatch Reduction
Shephard, S., C.A. Goudey, A. Read, and M.J. Kaiser A hydrodredge was tested using water pressure created from the hydrodynamics of the gear to lift scallops out of the seabed. The hydrodredge when compared to a more traditional dredge increased catch of surface-dwelling scallops but decreased catch of deeper-dwelling scallops. Bycatch of starfish, crabs and […]
