1. Interim protocol for fish/fish larvae by-catch observation in krill fishery

   fish identification can also be verified by the CCAMLR fish experts by using systematically archived ... images. It is also designed so that the data can be validated later by using randomly kept samples by the ... flag states. This protocol will be used only for Fish and Larval fish by-catch observation, and ... therefore the rest of the observation must be undertaken using the usual CCAMLR observer manual. This manual ...

6. Variation in echosounder calibration with temperature and some possible implications for acoustic surveys of krill biomass

   calibration parameters were to be employed on survey around South Georgia, and no account were taken of the ... differences in gain settings, then integrated 120 kHz echo signals would be under-reported by 2.8 dB, leading ... in turn to an under-estimation of krill biomass by 52.5 %. Every effort should therefore be made to ... are to be conducted. In addition, the implications of temperature variation across a survey area for ...
