Abstract: Abstract:Pellet feed loss is a major concern in sea cage culture. Underwater camera connected to a TV recording system for estimating pellet feed loss was employed in the tank experiments of cobia Rachycentron canadum. The results showed that fish in camera-monitored tank gave better control and a lower rate of pellet loss. The average improvement was approximately 10%. It is also concluded that subsurface-feeding activities is a better indicator of satiety in cobia culture.
(中文摘要:餌料殘留是箱網養殖引起環境污染的主要因素之一,我們使用水底攝影機監控海鱺在水槽中的飼養實驗並計算其殘餌量,實驗結果顯示利用水底攝影機進行監控的水槽飼養可有效降低殘餌量,由水底攝影機監控中所得的殘餌量與實際殘餌量數值誤差約為10%。結果顯示出在海鱺水槽飼養實驗中,水面下的覓食活動是顯示其飽食狀態的較佳指標。)
