The OCN rescue team has returned from our first excursion up the Namibian Coast! We had the privilege to be invited by the Namibian Ministry of Fisheries and Marine Resources to join six government officials on an expedition up the Skeleton Coast National Park to assist with drone surveys, scat collection and pup sampling at four major colonies North of Walvis Bay, and to show our seal disentanglement work. Scat collections are a smelly affair, but a lot of valuable information can be gathered regarding their diets, and the movements of seals, based on what they are eating.
We travelled for six days and set up wild camps in different spots each night, as there is no proper infrastructure close by. No running water, no electricity, no facilities, no cell coverage. We started at Cape Cross and rescued a seal pup from a packaging strap, but we did not find any other seals in need for the rest of the morning. We took it as a good sign, as Cape Cross is usually a hotspot for entanglements. It could be that the Corona crisis has lead to less commercial fishing and less recreational beach goers, which could have had a positive effect on the well-being of our seal population.
We moved on to Mowe Bay, about 500 km away from home. The resident seal colony at Mowe Bay is similar in size to the one at Cape Cross. We found a big female seal with a very deep cut around her neck. We removed a very strong, perfectly spliced loop of white rope stuck from her neck, the same kind of rope we found on two additional seals that day.
Entanglements were only a small part of our mission. Together with the ministry team we put our three new "pup nets" to the test. Little pups are strong and fast, and it is quite a tiring process getting 50 of them caught at each colony, then into nets, then onto the scale and finally released into the sea. In our "off" time, we quickly rescued a few more seals from entanglement. It was a bittersweet moment - the excitement about being able to help those remote seal colonies was overshadowed by the realisation that our animals will never be safe from plastic pollution and ocean rubbish, even 500km away from the closest harbour town.
