Researchers believe that California blue whales have recovered in numbers and the population has returned to sustainable levels. Scientists say this is the only population of blue whales to have rebounded from the ravages of whaling. The research team estimate that there are now 2,200 of these giant creatures on the eastern side of the Pacific Ocean. But concerns remain about their vulnerability to being struck by ships. At up to 33m in length and weighing in at up to 190 tonnes, blue whales are the largest animals on the planet. The California variety is often seen feeding close to the coast of the state, but they are found all the way from the Gulf of Alaska down to Costa Rica…..
WHALE ALERT WEST COAST
Endangered whales are needlessly being hit and killed by ship strikes each year along the West Coast of the United States. Prime collision areas are concentrated around busy shipping lanes in the San Francisco and Channel Islands regions. The Whale Alert – West Coast program wants to invite you – nature lovers, fishers, and mariners – to help reduce ship strikes to whales: The success of Whale Alert – West Coast depends on your increased participation and willingness to contribute observations taken while whale watching from land and at sea along the coast. Whale Alert – West Coast was formed by The Office of the National Marine Sanctuaries, Conserve.IO and Point Blue Conservation Science, working in coordination with the International Fund for Animal Welfare (IFAW), to help reduce the number of ship collisions with whales.
