A combination of different factors has the immune system of Dolphin calves weakened. Recorded via the mother’s milk toxins such as DDT and PCBs, made them vulnerable to diseases. In addition an additional weakening of the population by inbreeding. Porpoise mutilated by fishermen; Photo: C.J.CamphuysenAuch off the coasts of Germany fights a small species largely unnoticed for survival: after the IUCN Red list is the inventory of “our” porpoise (Phocoena phocoena) as endangered. Of the Eastern subspecies of the Baltic harbour porpoise that has settled as a separate population in the Central Baltic Sea on the so-called Darsser threshold, there are only 200 to 600 animals. Thus, it belongs to the small whale populations are most at risk in Europe. Main risk factor is that – as so often – fishing, in this case with reason gill nets, where the small whales regularly drown. Aid projects set bailout for a stray DelfinNaturschutzorganisationen such as the society for the rescue of dolphins for the “forgotten whales” because even less on the IWC or semi-State or State solutions, but take the initiative against the unnoticed disappearance of “forgotten whales” as in the coastal waters of Croatia together with local partners.
Lives there (yet) a small population of about 220 bottlenose. They are the last survivors of an once numerous – and species-rich holdings in this part of the Mediterranean. Pollution, overfishing and direct killing are responsible for the drastic shrinkage of the charismatic sea mammals. The successful german Croatian project “Rescue the last Adriatic Dolphin” was founded to stabilize the stock several years ago. Try local dolphin protection with German support and funding in the South of Peru, in the area of the Paracas peninsula, insert for the survival of the local dolphin populations in the region. With targeted projects a threat cocktail is consisting of direct hunting, illegal dynamite fishing, use of dolphin meat as bait to catch sharks, Combat marine pollution and industrial fishing. World’s work in this way in particular small conservation organisations with targeted and very effective protection projects for the small whales and put critical counterpoints against forgetting and the failure of IWC, CITES and other verburokratisierter species protection instruments.
