Estimates of Blacklip Abalone (Haliotis rubra) mortality rates attributed to Southern Rock Lobster (Jasus edwardsii)

Predation mortality rates of blacklip abalone (Haliotis rubra) were estimated under several different conditions using a range of manipulative experiments.Abalone mortality rates were estimated from tethering experiments inside the Maria Island Marine Reserve (MIMR) and at an adjacent site where predators, including southern rocks lobster (Jasus edwardsii) were in low abundance, due to fishing.Estimates of abalone mortality directly attributed to rock lobsters were gained from manipulative experiments inside the MIMR and in an aquarium experiment at the Tasmanian Aquaculture and Fisheries Institute facility at the Marine Research Laboratories.

通过一系列操控实验，在多种不同条件下对黑唇鲍（Haliotis rubra）的捕食死亡率进行了估算。鲍的死亡率通过在玛丽亚岛海洋保护区（Maria Island Marine Reserve，MIMR）内以及邻近的一个因捕捞导致捕食者（包括南方岩龙虾（Jasus edwardsii））数量较低的地点开展的系留实验估算得出。直接归因于岩龙虾的鲍死亡率估算值，来自于MIMR内的操控实验以及塔斯马尼亚水产养殖与渔业研究所（Tasmanian Aquaculture and Fisheries Institute）下属海洋研究实验室进行的水族箱实验。
