The team took skin samples from 10 blues and hope this will help them to track their genetic diversity and lineage. According to Oestreich, understanding their season movements is key to protecting blue whale populations. Some of the biggest individuals may eat up to 6 tons of krill in 1 day. The information gathered from this fieldwork is used as the basis for population modelling which produces an abundance estimate. In total, 41 blue whales have been photo-identified from South Georgia between 2011 and 2020, although none of these matched the 517 whales in the current Antarctic blue whale … Oregon State University researchers who recently discovered a population of blue whales in New Zealand are learning more about the links between the whales… Blue whales are the largest animals ever to live on our planet. Blue whales were nearly hunted to extinction in the 19th and 20th centuries by commercial whalers until the International Whaling Commission banned the taking of blue whales in 1967. In total, 41 blue whales have been photo-identified from South Georgia between 2011 and 2020, although none of these matched the 517 whales in the current Antarctic blue whale photographic catalog. The two main objectives for blue whales are to 1) increase blue whale resiliency and ensure geographic and ecological representation by achieving sufficient and viable populations in all ocean basins and in each recognized subspecies, and 2) increase blue whale resiliency by managing or eliminating significant anthropogenic threats. Vessel-based and aerial sighting surveys, acoustic monitoring, and analysis of individual animal markings are techniques used independently or in conjunction with each other to count whales. Blue whale, (Balaenoptera musculus), also called sulfur-bottom whale, the most massive animal ever to have lived, a species of baleen whale that weighs approximately 150 tons and may attain a length of more than 30 metres (98 feet).
