Die W\u00eareldnatuurfonds (WWF) en die Universiteit van Pretoria se walviseenheid van die Soogdiernavorsinginstituut werk nou saam om die gevare wat die suidelike walvisse in die gesig staar teen te werk.<\/p>\n\n\n\n
Nie net is die warmer water \u2018n bedreiging vir die walvisse nie, maar die voedselvoorraad word ook as \u2018n probleem gesien.<\/p>\n\n\n\n
Die walviseenheid van die UP doen al sedert 1969 navorsing op die suidelike walvisse en maak gebruik van foto-identifikasie en ander opnames om hul datastelsel op datum te hou. Di\u00e9 datastelsel word as van die beste ter w\u00eareld beskou.<\/p>\n\n\n\n
Die getalle van die suidelike walvisse het 10 jaar gelede toegeneem, veral nadat kommersi\u00eble walvisjag verbied is. Maar nou, met die warmer oseane en veranderinge seeprosesse, staar die suidelike walvisse weer uitsterwing in die gesig. Volgens navorsing speel die klimaatsveranderinge \u2018n merkwaardige rol in die aantal walvisse wat Suid-Afrika besoek.<\/p>\n\n\n\n
Met die ondersteuning van die WWF hoop die UP dat sy walviseenheid nou meer navorsing oor die walvisse kan doen, wat nie net toeriste na Hermanus en die res van die Overberg lok nie, maar wat ook geld in die streke inbring.<\/p>\n\n\n\n
\u201cSedert kommersi\u00eble walvisjag gestaak is, was die toename in getalle van die walvisse baie suksesvol,\u201d het dr. Els Vermeulen, navorsingbestuurder van die walviseenheid ges\u00ea. \u201cMaar nuwe navorsing wys dat klimaatsverandering weer hernieude druk op die walvisse plaas, hulle is byvoorbeeld maerder, kalf minder en verlaat hul broeiplekke vroe\u00ebr.\u201d<\/p>\n\n\n\n
Navorsing het gewys dat in Oktober verlede jaar daar 414 walvisse tussen Nature\u2019s Valley en Muizenberg getel is. Daar was 191 koeie met kalfies wat veral tussen die De Hoop-natuurreservaat en Walker Bay gesien is. \u201cDie getal is wel meer as in 2019 en 2020, maar is steeds minder as wat die normaal is,\u201d het Els ges\u00ea.<\/p>\n\n\n\n
Wat die navorsing ook wys en wat \u2018n bekommernis vir menige is, is die feit dat die koeie hul broeiplekke vroe\u00ebr verlaat wat weer die lewe van die kalfies bedreig.<\/p>\n\n\n\n
Om aan te gaan met hierdie merkwaardige navorsing het die walvisinstituut jou hulp nodig. Jy kan byvoorbeeld \u2018n walvis \u201caanneem\u201d en so bydrae tot die wonderlike navorsing. Al die geld wat ingesamel word, gaan om navorsing om die walvisse. Vir meer inligting besoek https:\/\/donate.wwf.org.za\/adoption\/adopt-a-whale <\/p>\n","protected":false},"excerpt":{"rendered":"
