6. Horizontal and vertical distribution and demography of euphausiids in the Ross Sea and its adjacent waters in 2004/2005

   Abstract:  The horizontal and vertical distribution and population structure of euphausiids in the Ross Sea and its adjacent waters were investigated during the summers of 2004/2005 using stratified towed samples. Nine species of euphausiids occurred in the survey area. Among them, Euphausia

7. The impact of the hake Merluccus spp. longline fishery off South Africa on Procellariiform seabirds

   Abstract:  In 1994, an experimental longline fisheri for hake Merluccius spp. commenced in the shelf water of South Africa. Participants were required to record any birds caught, and these data were supplemented by ship-based observers on several vessels. Longlines are set at night, and the white
