ADDITIONAL RECENT DISCOVERIES

RARE FISHES:

  • The rare sandy filefish, Thamnaconus arenaceus, was caught by novice diver and Rhodes Student Ntobeko Bacela on a fish collection dive at Aliwal Shoal. Ntobeko’s fish is only the fourth known specimen of this rare species, and the 2nd specimen to be found in South African waters. The live colours of the sandy filefish were previously unknown.
  • Whitespotted electric ray, Narcine sp., this electric ray appears to be new (undescribed); it was recently photographed north of Durban by Dennis King. It was first recorded from South Africa by Stefania Lamberti’s photo of a specimen on Protea Banks.
  • The blackcap wrasse, Thalassoma genivittatum (Valenciennes, 1839), was previously known only from Aliwal and the Mascarene Islands (Mauritius & Réunion), but Piet Strauss recently gave us a photo that he took at Ponta do Ouro, Mozambique.
  • The grass klipfish, Pavoclinus graminis is usually found in weed in tidepools; we collected it at 27 m on Deep Cracker Reef at Aliwal.
NEW (IMPROVED) WORKSHEETS

The financial support provided by Sappi to the Project was greatly increased this year, and this essential funding allows us to develop the fish survey work and enables the East Coast Fish-Watch Project to produce more benefits to the members. The Fish-Watch method of using waterproof worksheets with colour paintings of South African fishes to identify the species in our area is proving very effective as a teaching and learning strategy to help divers identify the various species of our diverse fish fauna. Once they can put a name on a fish, they can then talk about it, learn more about it, and get to know its habits. This increased knowledge provides a greater awareness and appreciation of our fascinating fish diversity, makes SCUBA diving more interesting, and is essential to the understanding and wise use of our fish resources. Unlike our first three Worksheets, which were printed on paper and then laminated; our latest Worksheets (Nos. 4, 5, 6 & 7) have been printed directly on pvc plastic by Cardtronic, and this should provide a more durable Worksheet that will hold up better in the rough and tumble environment of dive boats, equipment bags and under the sea.
