Biology Faculty and Staff Publications

A novel method of isolating digestive gland cells in abalone was used to provide information on the metabolic activity of this gland in Haliotis kamtschatkana. Activity, expressed as percent ·change in Vo₂ of isolated cells before and after the addi­tion of glucose and amino acid substrates, was studied in relation to sex and to seasonal changes in gonad and digestive gland indices. At 3- to 4-mo intervals between May 1995 and July 1996, five collections of 10 adult abalone (equal sexes) were made from the West Coast of Vancouver Island, British Columbia. Each animal's live mass (without shell) was …
