Effects of macroalgal type and water temperature on macroalgal consumption rates of the abalone Haliotis diversicolor Reeve.

From: Journal of Shellfish Research | Date: December 1, 2005| Author: | Copyright information

ABSTRACT The Japanese abalone "tokobushi" (Haliotis diversicolor Reeve) supports a valuable fishery off Tanegashima Island, southern Japan. However, catches have been declining, probably caused by over harvesting and other factors. Understanding the effects of macroalgal type and water temperature on the consumption rates of tokobushi has applications for the management of its population such as to identify sites with appropriate quality and quantity of macroalgae and the favorable water temperature during stock enhancement. Under controlled conditions, the effects of macroalgal ...
