Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 49:939-944

Outdoor experimental streams were used to determine the effects of effluent on histopathology of rainbow trout (Oncorhynchus mykiss). Studies were conducted for 10–11 mo using biologically treated bleached kraft mill effluent at concentrations rang

The occurrence of cartilage canals in shark vertebrae

Autor: Alexander H. Walsh, John M. Hoenig

Publikováno v: Canadian Journal of Zoology. 60:483-485

Cartilage canals were found in the vertebrae of 16 species of sharks from five families. The canals variously contain blood vessels, lymph-like material, clumps of immature chondrocytes, unidentified amorphous material, or appear empty. Of 10 species

Skeletal lesions and deformities in large sharks

Autor: Alexander H. Walsh, John M. Hoenig

Publikováno v: Journal of wildlife diseases. 19(1)

Four blunt-snouted sandbar sharks (Carcharhinus plumbeus) were noted among 555 examined over a 13-yr period. Radiographs of one specimen revealed that the three rostral cartilage rods were abnormally short and failed to join at the anterior tip. The
