Mass stranding of pilot whales puzzles conservationists

  • Pilot whales are social animals and partly because of their being so- they are oftentimes involved in mass strandings.
  • Per record as many as several hundreds of pilot whales have been involved at one time in mass strandings.
  • Up to now nobody could give the real reasons why whale beachings happened.
  • Reasons like persistence to keep the group together, mis-navigation while pursuing prey, sonar defects and parasitic infections are mere guesswork.

Concerned people try to save 42 stranded pilot whales

Let's listen to this more vivid account of whale beachings and how and what the people did in the area to save them from total annihilation:.

Lots of whales got stranded on New Zealand's beaches

Department of Conservation Steve Bolten expressed satisfaction over the rescue efforts by saying: " Some 63 pilot whales stranded ... but it looks pretty good. We've got 43 live ones ". Bolten said a whale may have been sick or their sonars may have led them to shallow water and they lost their way out.

  • Earlier on that Saturday- December 26, 2009 in South Island- New Zealand - 105 also stranded long-finned pilot whales died, conservation officials said.
  • They were discovered late by a tourist plane pilot. Conservation workers who responded to the site found 2/3 of them already dead. They were in bad shape for they have been out of the water for a long time.
  • So Golden Bay Biodiversity Program Manager Hans Stoffregen ordered that the remaining 30 which were already half-alive be euthanized to spare them from further pain and agony.
  • The total pilot whales to die on New Zealand beaches that particular weekened was brought to 126.
  • During summers on their way to their breeding grounds from the antarctic waters- a big number of whales got stranded on New Zealand's beaches as they passed by.

Contrary to rescue efforts, whales are herded to beaches and slaughtered in other places

  • Laurels to Australian conservationists for your rescue efforts. May I raise a substance of irony here. While conservation officials and workers, Australians and other well-meaning individuals are deeply involved in the conservation, preservation and protection of this species and other marine life- the reverse is true in other parts of the globe.
  • Listen. The American Cetacean Society Fact Sheet states that in what is called 'Drive Fisheries" group of whales are herded to the beach for slaughter. This activity has taken place on Cape Cod, Newfoundland, the Faroe, Shetland and Orkney Islands, Iceland and Norway.
  • The whales are killed for meat, bone, fertilizer and oil.
  • The same source states that in one drive fishery alone in Newfoundland killed over 50,000 whales between 1951 and 1961.
  • The kill continues in places such as the Faroe Islands despite obvious decrease in whale population.
