Freshwater Ichthyology

Sandelia bainsii Sandelia bainsii

The department houses important historical collections of southern African freshwater fishes. Coverage is excellent especially from the Eastern and Western Cape Provinces and Kwazulu-Natal. The collections incorporate theholdings of the Natal Museum, which date from 1905, and the South African Museum, which date from 1875. The first major collection of freshwater fishes was made by Dr Rex Jubb in 1931. He and his wife worked at the Museum between 1959 - 1980 and produced the first book on the freshwater fishes of southern Africa.

 The collection comprises 14 200 accessions which total some 250 000 specimens, mostly stored in alcohol. Type specimens are housed separately.There is a growing collection of early life history stages of fishes whichincludes eggs, embryos and larval fish. These are all well documented withdrawings and photographs, an essential prerequisite, in view of the dynamic nature of development. To supplement the wet collections there are skeletal,x-ray and colour slide collections. Copies of original collection sheets are also maintained and the entire collection database is computerised.

 The collections are accessed by both national and international ichthyologists as well as by post-graduate students, and have recently been used by consultants involved in ecological impact assessments. The early life history data play an important role in evolutionary and conservation research and have been used to assess the status of Red Data Book species, of alien introductions and for establishing where the "hotspots" of endemism and species diversity occur in South Africa.

The computerised database is regularly accessed by the Natal Parks Board, Nature Conservation Departments in both the Eastern and Western Cape Provinces, University of Cape Town Freshwater Research Unit researchers and by consultants. Sections of the collection are also available for use by the Museum's Education and Display Departments.

Mazda Wildlife Fund has donated a Mazda 4x4 for the "Save the Sandelia" campaign which involves the local community, research and environmental education. WWF-SA are supporting the project. TOTAL SA have provided funds for a biodiversity poster.

Present research focuses on Sandelia bainsii (factsheet) and Galaxias zebratus (factsheet).

  The Curator has been involved in what is hoped to be a constructive controversy concerning the introduction of alien aquatic species into river systems. To effectively get this message through to as many people as possible it was first aired in the Mail & Guardian's Cutting Edge section, May 9-15, 1997, and later appeared in African Wildlife in their September/October 1997 edition. It has also been put on the internet Albany Museum, M&G and Rhodes University Flyfishing Society (RUFFS) and is linked to an excellent American web site on Desert Fishes. There have been some very heated letters sent to the Curatoron his stance and these are either available at the above sites or searchfor trout in the electronic Mail &Guardian . With 30% (3000 species) of the world's freshwater fish possibly going extinct within the next 20-30 years we must reduce the pressure on them where ever possible. Limiting introductions of aliens is one way.

The Albany Museum's close association with Rhodes University's Institute for Water Research, the Department of Ichthyology and Fisheries Science and the South African Institute for Aquatic Biodiversity make the collections important for study in a number of related research fields. Additional information on fishes maybe gleaned from the Ichthyology Web Resources site.
