Umzimvubu River Port St John’s, with a bit of foam flow this morning, which means inland areas have had some good rainfall. Very good news indeed.
We had around 32mm of rainfall here a few days ago and the foam flow seen this morning in the Umzimvubu River is the result of fairly decent rainfall in the catchment areas inland.
The red float that is seen in the picture is our listening station, which picks up sharks and fish that have satellite tags in them. This gives us a good indication of movement in the river, especially by the Zambezi sharks (Bull sharks) that have been tagged.
We strongly encourage catch & release practice to be done by all fishermen
The Umzimvubu River is a sanctuary for Zambezi Sharks. Each year the females give live birth in the river mouth and their young spend at least 2 years of their young lives in this river system, becoming familiar with moving in and out of fresh and salt water systems. An open river system is vitally important for this and is an incredible event of Nature that has taken place as far back as one can remember.
As river systems are closing up to the ocean due to silting, it reduces the number of available healthy river systems that Zambezi (Bull) sharks can make use of each year.
