Postrelease survival, movements and thermal habitats of pelagic sharks
Postrelease survival, vertical and horizontal movements, and thermal habitats of five species of pelagic sharks in the central Pacific Ocean Musyl et al. ABSTRACT: From 2001 to 2006, 71 pop-up satellite archival tags (PSATs) were deployed on five species of pelagic shark (blue shark ; shortfin mako ; silky shark ; oceanic
A migration mechanism for transfer of sharks from ethanol to aqueous glycerol solutions
Published in September 2011 MacLeod, I.D., and van Dam A.J. ABSTRACT: This paper presents a scoping study on the impregnation of glycerol into formaldehyde-fixed and aqueous-ethanol-preserved sharks. The weight increase and solution density changes were monitored in sequential baths of aqueous glycerol. Positive results included a return of the colour of the specimens, improved flexibility,
